Description

Technical Field

[0001] This utility model relates to the field of equipment manufacturing technology, and in particular to an automatic door and a constant temperature and humidity machine. Background Technology

[0002] A constant temperature and humidity chamber is a device that can precisely control and maintain the stable temperature and humidity within a specific space. It is widely used in environmental testing, industrial production, warehousing, and scientific research. The stability of the internal environment of a constant temperature and humidity chamber directly affects experimental accuracy, product storage quality, and production process effectiveness.

[0003] Currently, most temperature and humidity control machines use manual opening and closing doors. During frequent operation, the manual opening and closing of the door causes rapid air exchange between the inside and outside of the equipment, which can easily lead to drastic fluctuations in internal temperature and humidity. This not only requires the equipment to spend more time readjusting to the set parameters, affecting work efficiency, but may also adversely affect the items stored inside or the experiments being conducted due to unstable temperature and humidity. Manual operation relies on human judgment and execution, which can lead to problems such as untimely operation and inconsistent door opening and closing angles. This increases the risk of human error interfering with the equipment's operating environment. Furthermore, in scenarios where frequent door opening and closing is required, continuous manual operation also consumes a lot of manpower, increases the labor intensity of workers, and reduces the overall convenience of the work.

[0004] Therefore, there is an urgent need for an automatic door that can solve the problems of large temperature and humidity fluctuations, significant external interference, and high labor intensity for workers caused by manual door opening and closing. Utility Model Content

[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] This embodiment discloses an automatic door for sealing a constant temperature and humidity chamber, such as... Figure 1As shown, in this embodiment, the automatic door includes a door body unit 1, a drive unit 2, an environmental recognition unit, and a position recognition unit. The door body unit 1 includes a door frame 12 and two door bodies 11, which are slidably mounted on the door frame 12. The drive unit 2 is mounted on the door frame 12 and is connected to the two door bodies 11 via a transmission mechanism. The drive unit 2 drives the two door bodies 11 to open and close. The environmental recognition unit is electrically connected to the drive unit 2 and is used to identify the temperature and humidity inside the equipment. The position recognition unit is mounted on the door frame 12 and is used to identify and provide feedback on the current position of the door bodies 11 in real time. The automatic door can monitor the temperature and humidity inside the equipment in real time using the environmental recognition unit and accurately grasp the door's status using the position recognition unit. The drive unit 2 automatically completes the opening and closing of the door without manual operation. This reduces temperature and humidity fluctuations caused by manual opening and closing, ensuring a stable environment inside the equipment. It also saves manpower, reduces labor intensity, improves operational convenience and work efficiency, and avoids interference with the equipment's operating environment caused by improper human operation.

[0050] Specifically, such as Figure 1 As shown, in this embodiment, the drive unit 2 includes a first drive component 21, a transmission component 22, and a linkage component 23. The first drive component 21 is electrically connected to both the environment recognition unit and the position recognition unit. The transmission component 22 is installed on the top beam of the door frame 12, and the first drive component 21 is connected to the transmission component 22. The first drive component 21 is used to drive the transmission component 22 to work. The linkage component 23 is installed on the door frame 12, and the transmission component 22 is connected to the linkage component 23. The linkage component 23 is connected to the door body 11. The operation of the transmission component 22 drives the door body 11 installed on the linkage component 23 to slide relative to the door frame 12, which can accurately drive the door to complete the opening and closing action. In conjunction with the environment recognition unit and the position recognition unit, it can ensure the timeliness and accuracy of the door opening and closing, further reduce the fluctuation of temperature and humidity inside the equipment caused by improper door action, ensure environmental stability, improve the reliability of automatic door operation, better save manpower, reduce labor intensity, improve operation convenience and work efficiency, and avoid human operation interference.

[0051] Preferably, such as Figure 1As shown, in this embodiment, the first driving component 21 is a servo motor, which, with its high-precision speed and position control characteristics, accurately drives the transmission component 22 to work, and then drives the door body 11 to slide precisely through the linkage component 23, realizing precise control of the door's opening and closing actions. The servo motor can also better cooperate with the environmental recognition unit to monitor the temperature and humidity inside the equipment and the position recognition unit to provide real-time feedback on the door's position, ensuring that the door responds promptly and accurately when it needs to open and close, minimizing temperature and humidity fluctuations inside the equipment caused by improper door movements, further ensuring the stability of the internal environment, improving the reliability of the automatic door's operation, more effectively saving manpower, reducing labor intensity, improving operational convenience and work efficiency, and avoiding human interference. In other embodiments, the first driving component 21 can also be a stepper motor or a DC geared motor, etc.

[0052] Preferably, such as Figure 1 As shown, in this embodiment, the drive unit 2 also includes a handwheel 24, which is detachably connected to the transmission component 22. When the automatic control mode fails, the transmission component 22 can be driven to work by manually rotating the handwheel 24, thereby driving the linkage component 23 and the door body 11 to complete the opening and closing action. This ensures that the door can still operate normally when the automatic system is abnormal. The handwheel 24 drive can serve as a backup solution for the automatic drive mode, improving the emergency response capability and reliability of the automatic door. It avoids the door from being unable to operate due to the failure of the automatic control of the drive unit 2, which would affect the stability of the internal environment or normal operation of the equipment. At the same time, the detachable design will not interfere with the automatic operation of the transmission component 22 when the automatic mode is running normally, thus taking into account both the convenience of automatic control and the practicality of emergency manual operation.

[0053] Preferably, such as Figure 1As shown, in this embodiment, the transmission assembly 22 includes a driving wheel 221, a driven wheel set 222, and a timing belt 223. The driving wheel 221 is mounted on the top beam of the door frame 12, and the driven wheel set 222 is mounted on the left-right ends of the top beam of the door frame 12. The driven wheel set 222 is connected to the linkage assembly 23. The timing belt 223 is simultaneously sleeved on both the driving wheel 221 and the driven wheel set 222. The first driving member 21 drives the driving wheel 221 on the top beam of the door frame 12 to rotate. The driving wheel 221 drives the driven wheel set 222 mounted on the left-right ends of the top beam of the door frame 12 to rotate through the timing belt 223 sleeved on it. Since the driven wheel assembly 222 is connected to the linkage component 23, the rotation of the driven wheel assembly 222 will drive the linkage component 23 to move, thereby driving the door body 11 connected to the linkage component 23 to slide along the door frame 12, completing the opening and closing action of the door. The synchronous belt 223 transmission has the characteristics of precise transmission and smooth operation, which can ensure the consistency and accuracy of the door opening and closing process, reduce the shaking or jamming when the door slides, and thus, in conjunction with the environmental recognition unit and the position recognition unit, more effectively maintain the stability of temperature and humidity inside the equipment, improve the reliability and smoothness of the overall operation of the automatic door, and better play the role of saving manpower and improving efficiency. In other embodiments, the transmission component 22 can also be a gear and rack structure or a sprocket and chain structure, etc.

[0054] Preferably, such as Figure 1 As shown, in this embodiment, two sets of driven wheel sets 222 and two sets of linkage components 23 are provided. The driven wheel sets 222 are located at both ends of the top beam of the door frame 12 along the left and right directions. The two linkage components 23 are respectively installed on the two vertical frames of the door frame 12. The two linkage components 23 are respectively connected to the left and right sides of the door body 11, which can ensure that the left and right sides of the door body are subjected to balanced forces, so that the two linkage components 23 drive the two sides of the door body 11 to slide synchronously, realize the smooth opening and closing of the door, avoid tilting or jamming during sliding, improve the stability and accuracy of the door operation, further reduce the fluctuation of temperature and humidity inside the equipment caused by unstable door movement, and enhance the overall reliability of automatic door operation.

[0055] Optionally, such as Figure 1 As shown, in this embodiment, the driven wheel assembly 222 includes a first driven wheel 2221 and a second driven wheel 2222. The first driven wheel 2221 and the driving wheel 221 are on the same straight line in the left-right direction, and the first driven wheel 2221 and the second driven wheel 2222 are on the same straight line in the front-back direction. The second driven wheel 2222 is connected to the linkage component 23, which enables the driving wheel 221 to drive the first driven wheel 2221 to rotate through the synchronous belt 223. With the front-back collinear arrangement of the first driven wheel 2221 and the second driven wheel 2222, the power is stably transmitted to the second driven wheel 2222, thereby driving the linkage component 23 and the door body 11 to slide precisely.

[0056] Optionally, such as Figure 1 As shown, in this embodiment, the transmission assembly 22 further includes a tensioning wheel 224, which is installed on at least one side of the driving wheel 221, and / or on at least one side of the driven wheel assembly 222. The tensioning wheel 224 can adjust the tension of the synchronous belt 223, preventing the synchronous belt 223 from slipping due to slack or increasing wear due to excessive tightness. This ensures the stability and accuracy of power transmission in the transmission assembly 22, making the door opening and closing action smoother and reducing shaking or jamming during operation. Furthermore, it works with the environmental recognition unit and the position recognition unit to maintain stable temperature and humidity inside the equipment, improving the reliability and service life of the automatic door operation, and better playing the role of saving manpower and improving efficiency.

[0057] Specifically, such as Figure 1 As shown, in this embodiment, the tensioning wheel 224 is installed on the left and right sides of the driving wheel 221, and the tensioning wheel 224 is installed on the left and right sides of the driven wheel assembly 222.

[0058] Preferably, such as Figures 1-2 As shown, in this embodiment, the linkage component 23 includes a forward-rotating lead screw 231, a reverse-rotating lead screw 232, a first connecting member 233, a forward-rotating nut 234, and a reverse-rotating nut 235. The forward-rotating lead screw 231 is mounted on the door frame 12 and is connected to the output end of the transmission component 22. The reverse-rotating lead screw 232 is mounted on the door frame 12. The first connecting member 233 is connected to the tail end of the forward-rotating lead screw 231 and also to the head end of the reverse-rotating lead screw 232. The forward-rotating nut 234 is sleeved on the forward-rotating lead screw 231 and cooperates with it. One of the two door bodies 11 is connected to the forward-rotating nut 234. The reverse-rotating nut 235... 35 is mounted on and cooperates with the counter-rotating screw 232. The opposite of the two door bodies 11 is connected to the counter-rotating nut 235. Driven by the transmission component 22, the forward rotating screw 231 and the counter-rotating screw 232 rotate synchronously. Because they rotate in opposite directions, the forward rotating nut 234 and the counter-rotating nut 235 drive the two door bodies 11 to close towards each other or open away from each other. This ensures the synchronicity and symmetry of the movement of the two door bodies 11, making the door opening and closing smoother and more precise, reducing jamming or offset caused by uneven force. Furthermore, it works with the environmental recognition and position recognition units to maintain the stability of the internal environment of the equipment, improving the reliability and efficiency of the automatic door operation. In other embodiments, the linkage component 23 can also be a double rack and pinion structure or a gear set and slider guide rail structure, etc.

[0059] Preferably, such as Figures 1-2As shown, in this embodiment, the linkage component 23 further includes a second connector 236 and a guide plate 237. The second connector 236 is installed on the forward-rotating nut 234 or the reverse-rotating nut 235, and is also connected to the door body 11. The guide plate 237 is installed on the door frame 12, and is disposed inside the vertical frame of the door frame 12 and spaced apart from the vertical frame. The guide plate 237 extends along the extension direction of the vertical frame of the door frame 12, and a guide groove is provided on the guide plate 237. The guide groove extends along the extension direction of the guide plate 237, and the second connector 236 is disposed in the guide groove, which can move along the door body 11 with the forward-rotating screw 231 or the reverse-rotating screw. During the movement of 232, the guide groove limits and guides the second connector 236, guiding the door body 11 to slide stably along the extension direction of the guide plate 237. This effectively prevents the door body 11 from deviating, tilting, or shaking during the sliding process, further ensuring the synchronicity and symmetry of the movement of the two door bodies 11. This makes the opening and closing action of the door smoother and more precise, reduces the fluctuation of temperature and humidity inside the equipment caused by unstable door sliding, enhances the reliability of automatic door operation, reduces frictional wear between the door body and the door frame 12, extends the service life of the equipment, and better cooperates with the environmental recognition unit and the position recognition unit to maintain the stability of the internal environment of the equipment, improving the ease of operation and work efficiency.

[0060] Preferably, in this embodiment, the linkage component 23 further includes four second connectors 236. The four second connectors 236 are respectively installed on two forward-rotating nuts 234 and two reverse-rotating nuts 235. The second connectors 236 are also connected to the door body 11. Under the drive of the forward-rotating screw 231 and the reverse-rotating screw 232, the two door bodies 11 achieve more stable and synchronous closing towards each other or opening away from each other through the second connectors 236. This avoids the door bodies 11 from shaking, tilting, or jamming due to unstable connection during sliding, ensuring the accuracy and smoothness of the door opening and closing action. This better coordinates with the environmental recognition unit and the position recognition unit, reducing temperature and humidity fluctuations inside the equipment caused by improper door movement, further ensuring the stability of the internal environment, improving the reliability and safety of the automatic door operation, extending the equipment's service life, and more effectively saving manpower, reducing labor intensity, and improving operational convenience and work efficiency. In other embodiments, the number of second connectors 236 may also be six, eight, or ten.

[0061] Preferably, in this embodiment, the environmental identification unit includes a temperature sensor and a humidity sensor. The temperature sensor is installed on the door body 11 and electrically connected to the drive unit 2. The temperature sensor is used to sense the temperature inside the device. The humidity sensor is also installed on the door body 11 and electrically connected to the drive unit 2. The humidity sensor is used to sense the humidity inside the device. It can sense the temperature and humidity information inside the device in real time and transmit it to the drive unit 2, thereby achieving real-time monitoring of the environmental parameters inside the device. In other embodiments, the environmental identification unit can also be an integrated temperature and humidity sensing structure or an intelligent environmental monitoring module with data transmission capabilities.

[0062] Preferably, in this embodiment, the position recognition unit includes three sets of infrared sensors, which are installed on the vertical frame of the door frame 12. One set of infrared sensors is located at the closing point of the two door bodies 11 to detect whether the two door bodies 11 are fully closed. The remaining two sets of infrared sensors are respectively located at the end of the travel of the two door bodies 11 to detect whether the door bodies 11 are fully open. This provides accurate position feedback to the drive unit 2, ensuring that the door opening and closing actions are in place, avoiding temperature and humidity fluctuations inside the equipment due to incomplete door closure or over-opening, while improving the reliability and accuracy of the automatic door operation. It also better cooperates with the environmental recognition unit to maintain a stable internal environment, further saving manpower and improving work efficiency. In other embodiments, the position recognition unit can also be a combination of a magnetic ruler and a magnetic head structure or an encoder and a synchronous shaft structure, etc.

[0063] Preferably, in this embodiment, the door body 11 includes a door shell and an insulation filler. The door shell is slidably mounted on the door frame 12 and is made of stainless steel. The insulation filler is filled inside the door shell and is made of polyurethane foam. The door body 11 achieves stable sliding assembly with the door frame 12 through the stainless steel door shell. Its robust and corrosion-resistant properties ensure long-term smooth operation of the door. The internal polyurethane foam insulation effectively blocks the exchange of heat and humidity between the inside and outside of the equipment, enhancing the sealing and insulation performance of the door. The door body 11, in conjunction with the environmental recognition unit and the position recognition unit, further reduces the temperature and humidity fluctuations inside the equipment caused by the insufficient performance of the door body 11 itself, and maintains the internal environment of the equipment more stably. Furthermore, the durability of the stainless steel shell reduces the maintenance frequency and cost, improving the overall service life and practical reliability of the automatic door.

[0064] Specifically, in this embodiment, the door shell is made of SUS304 stainless steel. This material not only has excellent corrosion resistance and oxidation resistance, but also can adapt to the complex temperature and humidity environment that may exist inside the equipment, ensuring the long-term stable operation of the door shell and reducing maintenance needs. Its good mechanical properties can also ensure that the sliding assembly between the door and the door frame 12 is more stable, avoiding problems such as poor sliding caused by material deterioration. Preferably, in this embodiment, the automatic door also includes a controller, which is installed on the door frame 12. The controller is electrically connected to the drive unit 2, the environmental recognition unit, and the position recognition unit, respectively. It can receive temperature and humidity data monitored by the environmental recognition unit and door position information fed back by the position recognition unit. By analyzing and processing this information, it can accurately control the operation of the drive unit 2, thereby achieving more intelligent and coordinated overall control of the automatic door. This allows for closer cooperation and more timely response between the units, further improving the accuracy and timeliness of door opening and closing, reducing temperature and humidity fluctuations caused by cooperation deviations that may occur due to the independent operation of each unit, and more effectively ensuring the stability of the internal environment of the equipment. At the same time, it enhances the automation and intelligence level of the automatic door operation, further saving manpower, reducing labor intensity, and improving operational convenience and work efficiency.

[0065] It should be noted that the controller is an existing structure, and setting up a controller in an automatic door is a common practice in this field. In this embodiment, any device in the prior art can be used, and any electrical connection method in the prior art can be used to connect the controller to the drive unit 2, the environment recognition unit, and the position recognition unit respectively. As long as the control system has the function of controlling the drive unit 2, it is sufficient, and will not be described in detail.

[0066] In summary, the automatic door disclosed in this embodiment uses a sliding assembly method where the two door bodies 11 are mounted on the door frame 12. Compared to the traditional outward or inward opening method of swing doors, it eliminates the need for additional space for door rotation, greatly reducing the external space occupied by the door during operation. The door bodies 11 slide precisely along the track of the door frame 12, with a fixed and compact movement trajectory, avoiding space waste caused by door swaying or offset. Simultaneously, the transmission component 22 of the drive unit 2 is mounted on the top beam of the door frame 12, and the linkage component 23 is mounted on the vertical frame of the door frame 12. All core drive components are integrated within the structure of the door frame 12, eliminating the need for additional external or internal space, achieving a compact design where structure equals space. This compact sliding structure and integrated drive layout reduce its own space occupation and allow for flexible adaptation to the size and functional requirements of various models of constant temperature and humidity machines.

[0067] Preferably, such as Figure 1As shown, in this embodiment, the automatic door also includes a support base 3, which is located at the bottom of the door frame 12. The support base 3 provides a stable bottom support for the door frame 12, enhances the stability and load-bearing capacity of the overall structure of the door frame 12, and prevents the door frame 12 from shaking or shifting due to the force generated when the door body 11 slides. This ensures the accuracy of the sliding track of the door body 11, thereby ensuring the smoothness and accuracy of the door opening and closing action. Furthermore, in conjunction with the drive unit 2 components such as the transmission component 22 and the linkage component 23, as well as the environmental recognition unit and the position recognition unit, it reduces the deviation of the door action caused by the instability of the door frame 12, thereby reducing the possibility of temperature and humidity fluctuations inside the equipment, ensuring the stability of the internal environment of the equipment, and improving the durability and safety of the overall structure of the automatic door, extending the service life of the equipment, and better playing the role of saving manpower and improving efficiency.

[0068] Optionally, in this embodiment, four support seats 3 are provided, which are respectively located at the four vertices of the bottom of the door frame 12. The two adjacent support seats 3 are spaced apart, which can form a balanced and stable support structure from the key stress points at the bottom of the door frame 12. By dispersing the pressure and force generated when the door frame 12 and the door body 11 slide, the overall stability of the door frame 12 is further enhanced, effectively preventing the door frame 12 from tilting, shaking or displacing due to uneven force, ensuring the accuracy of the sliding track of the door body 11, and ensuring the smoothness and accuracy of the door opening and closing action. The spaced arrangement can reduce the contact interference between the support seats 3 and the ground, adapt to different ground environments, improve the stability and adaptability of automatic door installation, and better maintain the stability of temperature and humidity inside the equipment in conjunction with other components, extend the service life of the equipment, and enhance operational reliability.

[0069] This embodiment also discloses a constant temperature and humidity machine. In this embodiment, the constant temperature and humidity machine includes a device body and an automatic door. The automatic door is installed on the opening side of the device body. The automatic door monitors the temperature and humidity inside the device body in real time through an environmental recognition unit and accurately grasps the door status in combination with a position recognition unit. The drive unit 2 automatically completes the opening and closing of the door without manual operation, thereby reducing temperature and humidity fluctuations caused by manual opening and closing of the door, ensuring the stability of the environment inside the device body, saving manpower, reducing labor intensity, improving ease of operation and work efficiency, and avoiding interference to the operating environment of the equipment caused by improper human operation. In this way, the constant temperature and humidity machine can stably maintain a constant temperature and humidity environment inside the device body, providing stable and reliable environmental conditions for items or experiments inside the equipment.

[0070] Preferably, in this embodiment, a double-layer high-temperature resistant and highly elastic sealing strip is provided between the automatic door and the equipment body. This can further enhance the sealing performance at the connection between the two. Its high-temperature resistance adapts to the high temperature environment that may exist inside the equipment body, while its high elasticity ensures that the sealing strip fits tightly with the automatic door and the equipment body, effectively blocking the exchange of heat and humidity between the inside and outside of the equipment. Combined with the automatic door's function of reducing temperature and humidity fluctuations, it can significantly reduce the changes in environmental parameters caused by door gaps, further ensuring the stability of the constant temperature and humidity environment inside the equipment body. The double-layer design ensures that even if one sealing strip ages or is damaged, the other layer can still play a sealing role, improving the reliability and durability of the sealing structure, reducing maintenance frequency, and thus better supporting the stable operation of the constant temperature and humidity machine, providing a more continuous and reliable environmental protection for items or experiments inside the equipment.
