Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection instruments, in particular to a door structure for a detection instrument and a control method thereof. BACKGROUND

[0002] The sample door of common detection instruments on the market, especially small detection instruments such as portable spectrometers, blood glucose meters, and intelligent nucleic acid detection instruments, is usually manually opened and closed, such as a flip cover, a sliding cover, or a plug-in cover. These traditional door opening methods require the user to directly contact the door, thereby bringing hand dander, grease, microorganisms, and other pollutants into the sensitive sample chamber or optical components, affecting the detection accuracy and instrument life. Especially in the laboratory batch detection scenario, manual operation is inefficient and it is difficult to ensure that the sealing force is consistent each time, which may cause environmental light leakage, dust intrusion, or unstable atmosphere, affecting the internal environment of the instrument. SUMMARY

[0003] Therefore, it is necessary to provide a door structure for a detection instrument and a control method thereof to solve the problem of inconvenient use of the door of the detection instrument. The door is automatically opened by a driving member, which facilitates sample entry and exit, reduces sample pollution, and improves detection accuracy and efficiency.

[0004] To solve the above technical problems, the present application provides the following technical solutions.

[0005] In a first aspect, the present application provides a door structure for a detection instrument, comprising a main frame, a door body, a driving member, a first connecting rod, and a second connecting rod. The main frame has a door opening, and the main frame has a U-shaped connecting piece. One arm of the U-shaped connecting piece is rotationally connected to the main frame, and the other arm is connected to the door body, so that the door body has an open door state and a closed door state. In the open door state, the door body is arranged at an angle with the main frame, and in the closed door state, the door body can close the door opening. One end of the first connecting rod is connected to the output shaft of the driving member, the other end of the first connecting rod is rotationally connected to one end of the second connecting rod, the other end of the second connecting rod is rotationally connected to the bottom of the U-shaped connecting piece, and the driving member is rotated to drive the U-shaped connecting piece to rotate relative to the main frame.

[0006] In one embodiment, in the open door state, the door body is arranged at a right angle with the main frame, and in the closed door state, the door body is arranged parallel to the main frame.

[0007] In one embodiment, the driving member is rotated by 180 degrees to switch between the open door state and the closed door state of the door body.

[0008] In one of the embodiments, the output shaft of the driving member, the rotation shaft of the first connecting rod relative to the second connecting rod, the rotation shaft of the second connecting rod relative to the U-shaped connecting member, and the rotation shaft of the U-shaped connecting member relative to the main frame are arranged in parallel.

[0009] In one of the embodiments, the main frame is rotationally connected with a door shaft, the U-shaped connecting member is provided with two U-shaped connecting members along the height direction of the door, the two U-shaped connecting members are connected with the door shaft, and the second connecting rod is rotationally connected with one of the U-shaped connecting members.

[0010] In one of the embodiments, the door structure further comprises a door state detector, the U-shaped connecting member is provided with an open door indicator, the door state detector is used to detect the open door indicator when the door body is in the open door state, and the door state detector is used to detect the first connecting rod when the door body is in the closed door state.

[0011] In one of the embodiments, the door structure further comprises a controller, the controller is electrically connected with the door state detector and the driving member, and is used to control the driving member according to the detection result of the door state detector.

[0012] In one of the embodiments, the door structure further comprises a current detector, the current detector is electrically connected with the driving member and is used to detect the current of the driving member, and the controller is electrically connected with the current detector and is used to control the driving member according to the detection result of the current detector.

[0013] In the second aspect, a control method for detecting an instrument door structure is provided, which is applied to the door structure described above and comprises the following steps: S10: receiving an opening or closing instruction by using a controller; S20: detecting the state of a door body by using a door state detector to obtain a detection result; S30: obtaining the detection result of the door state detector by using a controller; S40: when the door body is in a closed door state or an open door state, controlling the driving member to stop moving; otherwise, controlling the driving member to execute the opening or closing instruction.

[0014] In one of the embodiments, the door structure comprises a current detector, and the control method comprises the following steps: S50: setting an overload threshold in the controller; S60: detecting the current of the driving member by using the current detector during the movement of the driving member; S70: obtaining the detection current of the current detector. S80: When the detected current exceeds the overload threshold, control the drive component to stop moving.

[0015] The present invention has the following advantages: 1. The aforementioned door structure can be installed in portable spectrometers, blood glucose meters, intelligent nucleic acid detectors, and other testing instruments. The door structure comprises a main frame, a door body, a drive mechanism, a first connecting rod, and a second connecting rod. The main frame and door body are rotatably connected via a U-shaped connector. The drive mechanism, through the first and second connecting rods, drives the U-shaped connector to rotate, thereby driving the door body relative to the main frame, achieving the opening and closing of the door body. The first and second connecting rods and the U-shaped connector achieve the transmission output of the drive mechanism through a simple transmission structure, saving space and reducing costs. Simultaneously, the drive mechanism enables automated opening and closing of the door, facilitating sample entry and exit, reducing sample contamination, and improving detection accuracy and efficiency.

[0016] 2. The main frame is equipped with two U-shaped connectors, which are connected by the door pivot. Therefore, the drive unit only needs to drive one of the U-shaped connectors to drive the other door pivot to rotate, which not only simplifies the structure but also improves the stability and reliability of the door body rotation.

[0017] 3. The door structure is equipped with a door status detector, which can detect the status of the door body at any time. Therefore, the controller can accurately obtain the open and closed status of the door body through the door status detector, thereby accurately controlling the drive component to stop rotating, improving the intelligence level of the door structure, avoiding the drive component from spinning idly, and extending the service life of the drive component.

[0018] 4. The door structure is equipped with a current detector, which is used to detect the current of the drive component. During the rotation of the drive component, that is, during the rotation of the door body to close or open, if there is an obstacle between the door body and the main frame, it will cause the drive component to spin freely, resulting in current overload of the drive component. Therefore, when the controller obtains the detection result of the current detector and determines that the current is abnormal, it can control the drive component to stop rotating, which improves the automation level of the door structure and avoids damage to the drive component and damage to the door structure caused by abnormal closing.

Detailed Implementation

[0029] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] The following describes in detail the door structure and its control method in some embodiments with reference to the accompanying drawings.

[0031] like Figures 1 to 9As shown, in one embodiment, a door structure 100 for a testing instrument is disclosed, including a main frame 10, a door body 20, a driving component 40, a first connecting rod 41, and a second connecting rod 42; wherein, the main frame 10 has a door opening 15, and the main frame 10 has a U-shaped connector 30, one arm of the U-shaped connector 30 is rotatably connected to the main frame 10, and the other arm is connected to the door body 20, so that the door body 20 has an open state and a closed state; as Figure 1 and Figure 2 As shown, when the door is open, the door body 20 is set at an angle to the main frame 10, and when the door is closed, the door body 20 can close the door opening 15.

[0032] And, as Figure 5 As shown, one end of the first connecting rod 41 is connected to the output shaft of the drive member 40, the other end of the first connecting rod 41 is rotatably connected to one end of the second connecting rod 42, and the other end of the second connecting rod 42 is rotatably connected to the bottom of the U-shaped connector 30. The drive member 40 rotates to drive the U-shaped connector 30 to rotate relative to the main frame 10.

[0033] The aforementioned door structure 100 can be installed in testing instruments such as portable spectrometers, blood glucose meters, and intelligent nucleic acid detectors. The door structure 100 comprises a main frame 10, a door body 20, a drive component 40, a first connecting rod 41, and a second connecting rod 42. The main frame 10 and the door body 20 are rotatably connected by a U-shaped connector 30. The drive component 40 drives the U-shaped connector 30 to rotate via the first connecting rod 41 and the second connecting rod 42, thereby driving the door body 20 relative to the main frame 10, achieving the opening and closing of the door body 20. The first connecting rod 41, the second connecting rod 42, and the U-shaped connector 30 achieve the transmission output of the drive component 40 through a simple transmission structure, saving space and reducing costs. Simultaneously, the drive component 40 enables automated opening and closing of the door, facilitating sample entry and exit, reducing sample contamination, and improving detection accuracy and efficiency.

[0034] Specifically, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment, the driving component 40 is a driving motor, the first connecting rod 41 is sleeved on the output shaft of the driving motor, and a one-way bearing 43 is provided between the output shaft and the first connecting rod 41. The one-way bearing 43 can be a one-way needle roller bearing to prevent the first connecting rod 41 from rotating or shaking when the driving component 40 is running or stopping.

[0035] In this specific embodiment, the drive unit 40 can be a miniature DC planetary geared motor, which can ensure that the output torque of the drive unit 40 and the opening and closing speed of the compartment door are moderate.

[0036] The drive unit 40 can be a 16mm diameter DC planetary geared motor with a total reduction ratio of 1:500 and an actual motor speed of 15 r / min. The transmission mechanism consists of a crank-rocker mechanism composed of a first connecting rod 41, a second connecting rod 42, and a U-shaped connector 30. This mechanism converts the continuous rotational motion of the motor into the opening and closing swing of the door, thus transforming the high-speed rotation of the low-torque, high-speed DC motor into a high-torque, low-speed reciprocating rotational motion. This provides sufficient closing torque to ensure sealing while maintaining a compact design.

[0037] Specifically, such as Figure 5 and Figure 9 As shown, in one embodiment, the U-shaped connector 30 has a door connecting part 33 on one arm near the door body 20. The door connecting part 33 is arranged parallel to the bottom of the U-shaped connector 30. The door body 20 has a connecting protrusion and a connecting groove. The door connecting part 33 can be inserted into the connecting groove to realize the detachable connection of the U-shaped connector 30 and realize the convenience of installing and disassembling the door body 20.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, when the door is open, the door body 20 is set at a right angle to the main frame 10, and when the door is closed, the door body 20 is set parallel to the main frame 10.

[0039] Specifically, such as Figure 7 and Figure 8 As shown, in one embodiment, the drive member 40 rotates 180 degrees, causing the door body 20 to switch between an open state and a closed state.

[0040] Specifically, such as Figure 7 and Figure 8 As shown, in one embodiment, the output shaft of the drive member 40, the rotation axis of the first link 41 relative to the second link 42, and the rotation axis of the second link 42 relative to the U-shaped connector 30 are all arranged parallel to the rotation axis of the U-shaped connector 30 relative to the main frame 10.

[0041] Specifically, such as Figure 5 and Figure 9 As shown, in one embodiment, a door pivot 31 is rotatably connected to the main frame 10, and two U-shaped connectors 30 are provided along the height direction of the door. Both U-shaped connectors 30 are connected to the door pivot 31, and the second connecting rod 42 is rotatably connected to one of the U-shaped connectors 30.

[0042] The main frame 10 is provided with two U-shaped connectors 30, which are connected by the door pivot 31. Therefore, the drive unit 40 only needs to drive one of the U-shaped connectors 30 to drive the other door pivot 31 to rotate through the door pivot 31. This not only simplifies the structure but also improves the stability and reliability of the door body 20 rotation.

[0043] Furthermore, such as Figure 9 As shown, in one embodiment, the main frame 10 is provided with a first fixing member 11 and a second fixing member 12. The door pivot 31 passes through the first fixing member 11 and the second fixing member 12 in sequence and is rotatably connected to them. At the same time, the drive member 40 is fixed on the second fixing member 12, providing a good mounting structure for the drive member 40 and realizing stable driving of the first connecting rod 41 to rotate.

[0044] Specifically, such as Figure 6 and Figure 9 As shown, in one embodiment, the door structure 100 further includes a door status detector 50. The U-shaped connector 30 is provided with an opening indicator 32. When the door body 20 is in the open state, the door status detector 50 is used to detect the opening indicator 32. When the door body 20 is in the closed state, the door status detector 50 is used to detect the first connecting rod 41.

[0045] The door structure 100 is equipped with a door status detector 50, which can detect the status of the door body 20 at any time. Therefore, the controller 60 can accurately obtain the open and closed status of the door body 20 through the door status detector 50, thereby accurately controlling the drive component 40 to stop rotating, improving the intelligence level of the door structure 100, avoiding the drive component 40 from spinning idly, and extending the service life of the drive component 40.

[0046] Furthermore, such as Figure 9 As shown, in one embodiment, the door status detector 50 includes a first proximity switch 51 and a second proximity switch 52. The first proximity switch 51 is used to detect the door opening indicator 32, and the second proximity switch 52 is used to detect the first link 41. Therefore, when the door body 20 is in the open state, the first proximity switch 51 can detect the door opening indicator 32, and the controller 60 obtains the detection result of the first proximity switch 51. When the door body 20 is in the closed state, the second proximity switch 52 can detect the first link 41, and the controller 60 obtains the detection result of the second proximity switch 52.

[0047] In this specific embodiment, the first proximity switch 51 can be set on the first fixing member 11, and the door opening indicator 32 is set on the door pivot 31. When the door pivot 31 rotates with the U-shaped connector 30, the door opening indicator 32 also rotates, so that when the door is open, the first proximity switch 51 can detect the door opening indicator 32, and when the door is not open, the first proximity switch 51 has no detection signal.

[0048] Furthermore, the second proximity switch 52 and the drive unit 40 are mounted together on the second fixing member 12. Therefore, when the door body 20 is in the closed state, the second proximity switch 52 can detect the first linkage 41, while when it is not in the closed state, the second proximity switch 52 has no detection signal.

[0049] Furthermore, such as Figure 4 and Figure 6 As shown, in one embodiment, the main frame 10 is further provided with a light-shielding plate 13, which is connected to the first fixing member 11 and the second fixing member 12. The light-shielding plate 13 is used to block the light source from the door opening 15, improving the detection accuracy of the first proximity switch 51 and the second proximity switch 52. The light-shielding plate 13 can be set perpendicular to the main frame 10 to achieve a better light-shielding effect. An avoidance groove can also be provided on the light-shielding plate 13 to allow the U-shaped connector 30 to pass through, avoiding interference with the rotation of the U-shaped connector 30.

[0050] Specifically, such as Figure 9 As shown, in one embodiment, the door structure 100 further includes a controller 60, which is electrically connected to the door status detector 50 and the drive unit 40, and is used to control the drive unit 40 according to the detection result of the door status detector 50.

[0051] Furthermore, in one embodiment, the controller 60 is mounted on the first fixing member 11 to facilitate electrical connection with the door status detector 50 and the drive member 40, thereby reducing the wiring length.

[0052] Specifically, such as Figure 1 As shown, in one embodiment, a button 14 is provided on the outside of the main frame 10. The button 14 is electrically connected to the controller 60 and is used to send an on or off command of the drive unit 40 to the controller 60.

[0053] Specifically, such as Figure 3 As shown, in one embodiment, the door structure 100 further includes a current detector 70, which is electrically connected to the drive unit 40 and is used to detect the current of the drive unit 40. The controller 60 is electrically connected to the current detector 70 and is used to control the drive unit 40 according to the detection result of the current detector 70.

[0054] The door structure 100 is equipped with a current detector 70, which is used to detect the current of the drive component 40. During the rotation of the drive component 40, that is, during the rotation of the door body 20 to close or open, if there is an obstacle between the door body 20 and the main frame 10, the drive component 40 will spin freely, resulting in an overload of the current of the drive component 40. Therefore, when the controller 60 obtains the detection result of the current detector 70 and determines that the current is abnormal, it can control the drive component 40 to stop rotating, thereby improving the automation level of the door structure 100 and avoiding damage to the drive component 40 and damage to the door structure 100 caused by abnormal closing.

[0055] In one embodiment, a control method for a detection instrument door structure 100 is provided, applied to the aforementioned door structure 100, comprising the following method: S10: The controller 60 receives an on or off command; S20: The state of the door body 20 is detected by the door status detector 50, and the detection result is obtained; S30: The controller 60 acquires the detection results of the door status detector 50; S40: When the door body 20 is in the closed or open state, the controller 60 controls the drive component 40 to stop moving; otherwise, the controller 60 controls the drive component 40 to execute the open or close command.

[0056] This control method is applied to the aforementioned door structure 100. The door status detector 50 can detect the status of the door body 20 at any time. Therefore, the controller 60 can accurately obtain the opening and closing status of the door body 20 through the door status detector 50, thereby accurately controlling the drive component 40 to stop rotating, improving the intelligence level of the door structure 100, avoiding the drive component 40 from spinning idly, and improving the service life of the drive component 40.

[0057] In one embodiment, the door structure 100 includes a current detector 70, comprising the following method: S50: Set the overload threshold in controller 60; S60: During the movement of the driving component 40, the current of the driving component 40 is detected by the current detector 70; S70: Acquire the detection current of the current detector 70; S80: When the detected current exceeds the overload threshold, the control drive 40 stops moving.
