Description

Technical Field

[0001] This application relates to the field of biological detection equipment technology, and in particular to an analyzer. Background Technology

[0002] An analyzer is a high-precision analytical instrument used to detect and analyze biomolecules. Since analyzers typically require the placement or removal of samples before and after analysis, designing an analyzer with a door that is easy to open, close, and lock is a problem that needs to be solved. Utility Model Content

[0003] This application provides an analyzer, which is used to at least solve the problem of inconvenient door opening, closing and locking.

[0004] This application provides an analyzer, which includes a housing, an opening and closing device, and a locking device, wherein:

[0005] The shell has a support space for placing analytical samples, and an opening is formed on one side of the shell;

[0006] The opening and closing device includes a door panel assembly and a connecting assembly. The door panel assembly is movably connected to the housing via the connecting assembly. The door panel assembly is used to cover the opening when it is moved to a first position relative to the housing, and to open the opening when it is moved to a second position relative to the housing.

[0007] A locking device is disposed on the housing and is configured to engage with the door panel assembly to lock the door panel assembly when the door panel assembly is moved to a first position, and to unlock the door panel assembly under the action of a force, so that the door panel assembly can move relative to the housing.

[0008] In the analyzer of this application embodiment, the door panel assembly is movably connected to the housing via a connecting assembly. When the door panel assembly covers the opening of the housing, the locking device is fixedly connected to the door panel assembly, restricting the position of the door panel assembly relative to the housing. When the door panel assembly needs to be opened, a certain force is applied to the locking device to unlock the door panel assembly, allowing the door panel assembly to move to a second position relative to the housing via the connecting assembly, thereby opening the opening of the housing. This design enables one-click opening of the housing opening and facilitates door panel closure, improving ease of use.

[0009] In some embodiments, the connecting assembly includes a fixing part and a connecting part connected to the fixing part. The fixing part is fixedly connected to the housing, and the door panel assembly is fixedly connected to the end of the connecting part away from the fixing part. The connecting part is elastic and is used to drive the door panel assembly to move relative to the housing during the generation and recovery of elastic deformation.

[0010] In this way, one end of the connecting part is fixedly connected to the housing by the fixing part, and the door panel assembly is fixedly connected to the end of the connecting part away from the fixing part. Thus, the elasticity of the connecting part allows the door panel assembly to move relative to the housing. The structure is simple and easy to implement.

[0011] In some embodiments, the connecting portion is flexibly disposed on the fixing portion, and the connecting portion is configured to be wound in a relaxed state and to elastically deform and unfold under external force.

[0012] In this way, the connecting part can move the door panel assembly away from the fixed part when it generates elastic deformation, and move the door panel assembly relatively closer to the fixed part when it recovers elastic deformation, thereby making the movement of the door panel assembly relative to the housing highly reliable and easy to implement.

[0013] In some embodiments, the fixing part is located at the top of the housing, and the end of the connecting part that connects to the door panel assembly has a height difference with the fixing part in the vertical direction.

[0014] Thus, by fixing the part at the top of the housing, and connecting the end of the door panel assembly to the fixed part having a height difference in the vertical direction, the connecting part can drive the door panel assembly to move up and down, or the door panel assembly can move up and down to drive the connecting part to extend or roll, thereby opening or closing the opening when the door panel assembly moves up and down.

[0015] In some embodiments, the fixing part includes a bracket and a reel, the bracket is fixedly connected to the housing, the reel is rotatably connected to the bracket, and one end of the connecting part is fixedly connected to the reel so that the connecting part is wound or extended around the reel as an axis.

[0016] In this way, the bracket is fixedly connected to the housing, and the spool is rotatably connected to the bracket. The connecting part is wound or extended around the spool as the axis, which simplifies the structure of the connecting assembly and at the same time ensures the reliability of the winding and extension of the connecting part.

[0017] In some implementations, the connecting part is a coil spring.

[0018] In this way, the connecting part can provide good elastic support and restoring force for the door panel assembly, enabling the door panel assembly to open and close normally.

[0019] In some embodiments, the door panel assembly includes a door panel and a fastener, the fastener being disposed on the side of the door panel facing the load-bearing space and fixedly connected to one end of the connecting portion.

[0020] In this way, by setting the fastener on the side of the door panel facing the load-bearing space, and fixing the fastener to one end of the connecting part, the fastener and the connecting part can be covered by the door panel, which can improve the aesthetics and also improve the space utilization.

[0021] In some embodiments, the fastener has a first mounting hole, and the end of the connecting portion has a second mounting hole. The first mounting hole and the second mounting hole are opposite to and communicate with each other along the thickness direction of the fastener. The door panel assembly also includes a first fastener, which passes through the first mounting hole and the second mounting hole to fix the fastener and the connecting portion.

[0022] Thus, by connecting the first mounting hole and the second mounting hole along the thickness direction of the fastener, and by inserting the first fastener through the first mounting hole and the second mounting hole, the fastener and the connecting part are fixedly connected, thereby improving the connection strength of the fastener and the connecting part, and thus improving the structural reliability.

[0023] In some embodiments, there are multiple first mounting holes, and the lines connecting any two of the first mounting holes form a first included angle with each other; there are multiple second mounting holes, and the lines connecting any two of the second mounting holes form a second included angle with each other.

[0024] Thus, with multiple first and second mounting holes, the lines connecting the two first mounting holes form a first angle with each other, and the lines connecting the two second mounting holes also form a first angle with each other. This allows the lines connecting the first fastener passing through the connecting part and the fastener's position to also form an angle with each other, thereby enabling the connecting part to rebound more smoothly and avoiding excessive curling.

[0025] In some embodiments, the analyzer further includes a guiding device that extends in a direction from a first position to a second position. The guiding device includes a first guide member connected to the housing and a second guide member connected to a door panel assembly. The second guide member is movably connected to the first guide member in the direction of extension of the guiding device.

[0026] Thus, by extending the guide device directionally from the first position to the second position, the first guide member is connected to the housing, the second guide member is connected to the door panel assembly, and the second guide member is movably connected to the first guide member along the extension direction of the guide device, thereby restricting the movement of the door panel assembly relative to the housing in the direction from the first position to the second position, and keeping the opening and closing of the door panel assembly stable.

[0027] In some embodiments, the analyzer includes a mounting frame for supporting a guide device, the mounting frame being erected in the bearing space and fixedly connected to at least one side wall of the housing, and a first guide member being fixedly mounted on the side surface of the mounting frame facing the door panel assembly.

[0028] Thus, by fixing the frame in the bearing space and fixing it to at least one side wall of the housing, the first guide is fixedly installed on the side surface of the frame facing the door panel assembly, thereby stably supporting the first guide and the second guide, which is beneficial to the stability of the first guide and the second guide in relative movement.

[0029] In some embodiments, the door panel assembly includes a door panel and a connecting block fixedly connected to a second guide member, the connecting block being disposed on the side of the door panel facing the load-bearing space, and the first and second guide members extending linearly along the height direction of the door panel.

[0030] Thus, the connecting block is fixedly connected to the second guide member. The connecting block is set on the side of the door panel facing the bearing space. The first guide member and the second guide member extend in a straight line along the height direction of the door panel, so that the second guide member and the door panel are spaced apart along the thickness direction of the door panel, avoiding the risk of structural interference when the door panel moves relative to the shell.

[0031] In some embodiments, the first guide includes a first slide groove, the second guide includes a second slide groove and a slider, the openings of the first slide groove and the second slide groove are opposite to each other and spaced apart, and the slider is clamped in the first slide groove and the second slide groove and is slidably engaged with the first slide groove and the second slide groove respectively.

[0032] Thus, the first and second slides are spaced apart with their openings facing each other, and the slider is clamped in the first and second slides and slides into the first and second slides respectively, thereby increasing the sliding stroke of the door panel under the condition that the lengths of the first slide, the second slide, and the slider are limited.

[0033] In some implementations, the side surface of the second guide member facing away from the slider mates with the connecting block to fix the connecting block to the second guide member.

[0034] Thus, the second guide is fixedly connected to the connecting block on the side surface away from the slider, thereby making the structure compact and reducing structural interference.

[0035] In some embodiments, there are two guide devices, which are respectively arranged on both sides of the opening along the width direction of the analyzer.

[0036] Thus, by having two guide devices positioned on either side of the opening along the width of the analyzer, the door panel assembly can be limited and supported on both sides of the width direction by the guide devices, thereby improving the balance and stability of the door panel assembly relative to the housing.

[0037] In some embodiments, the locking device includes an interactive component and a locking structure connected to the interactive component, the interactive component being at least partially exposed on the outer surface of the housing, and the locking structure being detachably connected to the door panel assembly and configured to detach from the door panel assembly when the interactive component is subjected to a force.

[0038] Thus, by having the interactive components at least partially exposed on the outer surface of the housing, users can easily interact with and apply force to the interactive components. When the locking structure is connected to the door panel assembly, it can lock the door panel assembly. When the user applies force to the interactive components, the locking structure separates from the door panel assembly, that is, the door panel assembly is unlocked. At this time, the door panel assembly can move relative to the housing, making user operation simpler and more convenient.

[0039] In some embodiments, the locking device includes an elastic member that connects the interaction member and the locking structure. The elastic member is used to engage the locking structure with the door panel assembly when the locking structure is subjected to a force from the door panel assembly, and to push the interaction member to reset when the locking structure is separated from the door panel assembly.

[0040] Thus, when the locking structure is subjected to the force of the door panel assembly, the elastic component drives the locking structure to engage with the door panel assembly, and when the locking structure is separated from the door panel assembly, it pushes the interactive component to reset, thereby realizing the automatic locking of the door panel assembly by the locking device and the automatic reset of the locking device when the door panel assembly is unlocked, which facilitates the next locking operation.

[0041] In some implementations, the interactive component is a button, the elastic component is a spring, the button and the spring are stacked along the axial direction of the spring, and the axial direction of the spring forms an angle with the direction from the first position to the second position.

[0042] In this way, by stacking the button and the spring along the spring's axis, the user can push the spring to produce elastic deformation when pressing the button, making the operation more convenient. Furthermore, the spring's axis forms an angle with the direction from the first position to the second position. In other words, the direction of the spring's elastic deformation forms an angle with the direction of the door panel assembly's movement. This allows for effective locking and unlocking of the door panel assembly even with a small spring deformation range, saving torque.

[0043] In some embodiments, the door panel assembly includes a door panel and a limiting structure located at the end of the door panel in a direction from the second position to the first position. The limiting structure is used to engage with a locking structure to fix the door panel assembly to the locking device in the first position.

[0044] Thus, by engaging the locking structure with the limiting structure at the end of the door panel in the direction from the second position to the first position, the door panel assembly is fixedly connected to the locking device in the first position, which helps to improve the locking effect of the locking device on the door panel assembly and ensures controllable unlocking.

[0045] In some embodiments, the housing includes a first frame surrounding the opening, the locking device includes a mounting box and a lock cylinder at least partially disposed within the mounting box, the mounting box and the first frame together defining a mounting space, an elastic member is sleeved on the lock cylinder, and the same end of the elastic member and the lock cylinder axially is connected to an interaction member disposed on the first frame.

[0046] Thus, the lock cylinder is at least partially housed inside the mounting box, the elastic component is sleeved on the lock cylinder and the same end of the elastic component and the lock cylinder axis is connected to the interactive component, and the interactive component is located on the first frame, so that the interactive component can cooperate with the locking device and the limiting structure to realize the locking and unlocking of the door panel assembly.

[0047] In some embodiments, the limiting structure includes a limiting piece that extends and bends from the edge of the door panel toward the mounting box;

[0048] The locking structure includes a connecting end and a locking end. The connecting end is connected to the end of the lock cylinder away from the interactive parts and is set on the side wall of the mounting box away from the installation space. The locking end is connected to the connecting end and bends toward the limiting piece.

[0049] The locking end is used to engage with the limiting piece to lock the door panel assembly, and is also used to disengage from the limiting piece as the connecting end moves under pressure and deformation of the elastic member, so as to unlock the door panel assembly.

[0050] In this way, by bending the limiting piece towards the mounting box and the locking end towards the edge of the first frame, the limiting piece and the locking end are effectively engaged, ensuring the reliability of the locking device in locking the door panel assembly. Furthermore, when the elastic component is compressed, it can move the locking structure and disengage from the limiting piece, achieving one-button unlocking for easy user operation.

[0051] In some embodiments, the locking device further includes a lock housing and a lock cylinder sequentially fitted over the lock cylinder, both of which are housed in an installation space. The lock cylinder has openings at both ends along its axial direction. The lock housing includes an end face and a peripheral face. The end face is fixedly connected to a frame and covers one of the openings of the lock cylinder. The peripheral face surrounds the elastic member and the lock cylinder.

[0052] Thus, the lock shell and lock cylinder are sequentially fitted around the lock cylinder and are both located in the installation space. The end face of the lock shell is fixedly connected to the frame and covers one of the openings of the lock cylinder. The circumference of the lock shell surrounds the elastic component and the lock cylinder, making the locking device more compact and facilitating the unlocking and locking of the door panel assembly within the deformation range of the elastic component.

[0053] In some embodiments, the end face and the first frame together form a receiving hole, which penetrates the frame and the end face along its own axis. The receiving hole is used to accommodate the interactive component, and the elastic component and the lock cylinder pass through the receiving hole to connect with the interactive component.

[0054] The interactive component is configured to extend at least partially into the receiving hole as the elastic component undergoes elastic deformation, and is configured to exit at least partially out of the receiving hole as the elastic component recovers its elastic deformation.

[0055] In this way, the elastic component and the lock cylinder are connected to the interactive component through the receiving hole. The interactive component is at least partially inserted into the receiving hole as the elastic component deforms, and at least partially withdrawn from the receiving hole and exposed outside the frame as the elastic component recovers its deformation. This makes the different states of the interactive component more intuitive and easier for users to operate. It also makes the structure more compact and reduces the space occupied.

[0056] In some embodiments, the two ends of the lock cylinder axially abut against the end face of the lock housing and the wall of the mounting box, respectively, and a threaded structure is formed on the side of the circumference away from the elastic component. The threaded structure cooperates with the lock cylinder to fix the lock cylinder to the lock housing.

[0057] Thus, the two ends of the lock cylinder axially abut against the end face of the lock housing and the wall of the mounting box respectively, and a threaded structure is formed on the side of the circumference away from the elastic component. The threaded structure cooperates with the lock cylinder to fix the lock cylinder and the lock housing, thereby making the internal structure of the locking device compact and the connection stable.

[0082] Please see Figures 1-3 , Figure 3 The dashed line indicates the door panel assembly located in the second position. This application provides an analyzer 100, which includes a housing 10, an opening / closing device 20, and a locking device 30, wherein:

[0083] The housing 10 has a support space 101 for placing analytical samples, and an opening 102 is formed on one side of the housing 10.

[0084] The opening and closing device 20 includes a door panel assembly 21 and a connecting assembly 22. The door panel assembly 21 is movably connected to the housing 10 via the connecting assembly 22. The door panel assembly 21 is used to cover the opening 102 when it is moved to a first position relative to the housing 10, and to open the opening 102 when it is moved to a second position relative to the housing 10.

[0085] A locking device 30 is disposed on the housing 10. The locking device 30 is configured to cooperate with the door panel assembly 21 to lock the door panel assembly 21 when the door panel assembly 21 is moved to a first position, and to unlock the door panel assembly 21 when a force is applied, so that the door panel assembly 21 can move relative to the housing 10.

[0086] In the analyzer 100 of this application embodiment, the door panel assembly 21 is movably connected to the housing 10 via the connecting assembly 22. When the door panel assembly 21 covers the opening 102 of the housing 10, the locking device 30 is fixedly connected to the door panel assembly 21, restricting the position of the door panel assembly 21 relative to the housing 10. When the door panel assembly 21 needs to be opened, a certain force is applied to the locking device 30 to unlock the door panel assembly 21, so that the door panel assembly 21 can move to a second position relative to the housing 10 via the connecting assembly 22, opening the opening 102 of the housing 10. This design realizes one-click opening of the opening 102 of the housing 10 and facilitates closing of the door panel 211, improving the convenience of use.

[0087] Specifically, Analyzer 100 is a comprehensive instrument that analyzes and detects biological samples using one or more physical, chemical, or optical methods. It can be widely used in basic research, clinical diagnosis, forensic medicine, and industrial biotechnology. Nucleic acid fragment analysis is a typical application scenario for Analyzer 100. Analyzer 100 may include, but is not limited to, agarose gel electrophoresis systems, capillary electrophoresis instruments, real-time quantitative PCR (Polymerase Chain Reaction) instruments, or digital PCR instruments.

[0088] The process of nucleic acid fragment analysis using analyzer 100 typically includes sample preparation, reagent preparation and instrument calibration, sample loading, analysis execution, and data acquisition and processing. The analyzer 100 housing 10 houses analytical instruments (e.g., electrophoresis and imaging modules) and a carrier (e.g., a biochip) for holding the analytical samples. Sample loading refers to moving the analytical sample from opening 102 into the carrier space 101 and injecting it onto the carrier, such as the biochip. Before starting the analyzer, the housing 10 usually needs to close opening 102 to maintain the sealing of the carrier space 101. That is, the door assembly 21 is opened before each sample loading and closed after the sample is loaded and before the analyzer starts operation.

[0089] The housing 10 includes a top 13 and a bottom 14 facing each other, and a side wall 15 connecting the top 13 and the bottom 14. For ease of explanation, the direction in which the top 13 and the bottom 14 face each other is defined as the vertical direction, and the bottom 14 of the housing 10 is defined as one side of the mounting surface of the analyzer 100. The mounting surface of the analyzer 100 can be the ground, a table, a wall, etc.

[0090] The opening 102 can be formed on any side of the housing 10. For example, the opening 102 can be formed on the top 13 or on any of the front, rear, left, or right side walls 15, or it can be formed at the junction of the top 13 and any side wall 15. This application describes the opening 102 as being formed on the front side of the housing 10. The opening 102 can be square, circular, elliptical, polygonal, or other shapes, and this application does not limit it in this way.

[0091] The door panel assembly 21 can completely cover and close the opening 102. The first position is when the door panel assembly 21 completely covers the opening 102. In the second position, the door panel assembly 21 can maximize the opening of the opening 102. The door panel assembly 21 can either completely avoid the opening 102 or retain a small portion of its edge within the boundary of the opening 102. The shape and size of the outer boundary of the door panel assembly 21 correspond to and match the shape and size of the opening 102 to ensure that the door panel assembly 21 can completely cover the opening 102. The movement of the door panel assembly 21 relative to the housing 10 from the first position to the second position can include, but is not limited to, sliding, rotating, swaying, swinging, twisting, and ejection.

[0092] The locking device 30 may be located near the boundary of the opening 102 so that it can engage with the door panel assembly 21 in the first position for locking. The locking device 30 locks the door panel assembly 21 and may be detachably connected to the door panel assembly 21. For example, the locking device 30 may be connected to the door panel assembly 21 in the first position by at least one of the following methods: magnetic adsorption, adhesive, or snap-fit.

[0093] When the user needs to open the opening 102, the user can apply force to the locking device 30 by flicking, pressing, pulling or other actions. The locking device 30 disengages from the door panel assembly 21 in response to the force applied by the user, and the door panel assembly 21 moves from the first position to the second position relative to the housing 10 through the connecting component 22.

[0094] Conversely, when the user needs to close the opening 102, the user can apply force to the door panel assembly 21 by pressing, pulling, or other actions. Under the action of the user's force, the door panel assembly 21 moves from the second position to the first position relative to the housing 10, and connects with the locking device 30 in the first position to complete the locking. The above process of opening and closing the opening 102 can be repeated multiple times.

[0095] The connecting component 22 may include, but is not limited to, rods, shafts, belts, chains, ropes, gears, cams, slide rails, springs, spring sheets, coil springs 2224, etc., and the door panel component 21 can move through the cooperation of multiple components.

[0096] Please see Figure 2 and Figure 5In some embodiments, the connecting component 22 includes a fixing part 221 and a connecting part 222 connected to the fixing part 221. The fixing part 221 is fixedly connected to the housing 10. The door panel assembly 21 is fixedly connected to the end of the connecting part 222 away from the fixing part 221. The connecting part 222 is elastic and is used to drive the door panel assembly 21 to move relative to the housing 10 during the generation and recovery of elastic deformation.

[0097] Thus, by fixing part 221, one end of connecting part 222 is fixedly connected to housing 10, and door panel assembly 21 is fixedly connected to the end of connecting part 222 away from fixing part 221. The elasticity of connecting part 222 allows door panel assembly 21 to move relative to housing 10. The structure is simple and easy to implement.

[0098] Specifically, the fixing part 221 can be fixed at any position on the housing 10. To facilitate the connection between the connecting part 222 and the door panel assembly 21, the fixing part 221 can be set close to the opening 102. For example, the opening 102 includes four side edges: top, bottom, left, and right. The fixing part 221 can be set close to any side edge of the opening 102.

[0099] Combination Figure 3 The direction in which the connecting part 222 generates and recovers elastic deformation can be consistent with the direction in which the door panel assembly 21 moves from the first position to the second position or from the second position to the second position.

[0100] Please see Figure 2 and Figure 5 In some embodiments, the connecting portion 222 is foldably disposed on the fixing portion 221, and the connecting portion 222 is configured to be wound in a relaxed state and to elastically deform and unfold under external force.

[0101] In this way, the connecting part 222 can move the door panel assembly 21 away from the fixing part 221 when it generates elastic deformation, and move the door panel assembly 21 relatively closer to the fixing part 221 during the process of restoring elastic deformation, thereby making the movement of the door panel assembly 21 relative to the housing 10 highly reliable and easy to implement.

[0102] Specifically, the relaxed state of the connecting part 222 refers to the state in which the connecting part 222 does not undergo elastic deformation. The connecting part 222 includes a first end 2221 and a second end 2222. The first end 2221 is connected to the fixing part 221, and the second end 2222 is fixedly connected to the door panel assembly 21. In the relaxed state, the connecting part 222 is wound around the fixing part 221 as the axis. When the door panel assembly 21 is subjected to an external force, the second end 2222 of the connecting part 222 is indirectly subjected to the force, causing the connecting part 222 to undergo elastic deformation and unfold. The external force subjected to the door panel assembly 21 can be pressure, tension, or traction from the user, or pressure, tension, fastening force, or adsorption force applied to the door panel assembly 21 by the locking device 30.

[0103] For example, when the user closes the door, the door panel assembly 21 moves relative to the housing 10, and the second end 2222 moves with the door panel assembly 21 and moves away from the fixing part 221, while the connecting part 222 extends as a whole. Similarly, when the locking device 30 locks the door panel assembly 21, the second end 2222 remains in a position away from the fixing part 221 along with the door panel assembly 21, while the connecting part 222 remains extended as a whole.

[0104] When the locking device 30 unlocks the door panel assembly 21, the force exerted by the locking device 30 on the second end 2222 indirectly through the door panel assembly 21 disappears, and the connecting part 222 has a tendency to recover its elastic deformation. Then the connecting part 222 returns to the coiled state. During the coiling process, the second end 2222 approaches the fixing part 221, causing the door panel assembly 21 to move relative to the housing 10.

[0105] Please see Figure 2 and Figure 5 In some embodiments, the fixing part 221 is provided on the top 13 of the housing 10, and the connecting part 222 has a height difference with the fixing part 221 in the vertical direction at one end of the door panel assembly 21.

[0106] Thus, by fixing part 221 being set on top 13 of housing 10, and connecting part 222 having a height difference between one end of door panel assembly 21 and fixing part 221 in the vertical direction, connecting part 222 can drive door panel assembly 21 to move up and down, or the door panel assembly 21 can move up and down to drive connecting part 222 to extend or roll, so that opening 102 can be opened or closed when door panel assembly 21 moves up and down.

[0107] Specifically, the fixing part 221 can be disposed at the edge or center of the top 13 of the housing 10, and can be connected to the inner side of the top 13 of the housing 10 facing the bearing space 101, or it can be connected to the outer side of the top 13 of the housing 10 facing the external environment. The second end 2222 of the connecting part 222 is connected to the door panel assembly 21 and has a height difference with the fixing part 221 in the vertical direction. The second end 2222 can be located below the fixing part 221, that is, the second end 2222 is located below the first end 2221.

[0108] During the process of elastic deformation and unfolding of the connecting part 222, the door panel assembly 21 moves downward with the second end 2222 of the connecting part 222 until it completely covers the opening 102; during the process of elastic deformation and winding of the connecting part 222, the door panel assembly 21 moves upward with the second end 2222 until it completely opens the opening 102.

[0109] Optionally, the bottom 14 of the housing 10 can face downwards, i.e., vertically. When the connecting portion 222 is in the unfolded state, the first end 2221 and the second end 2222 can also have a positional difference in the horizontal direction, causing the second end 2222 and the door panel assembly 21 to move obliquely upwards when the connecting portion 222 is wound, and obliquely downwards when the connecting portion 222 is unfolded. Alternatively, the first end 2221 and the second end 2222 can be flush in the horizontal direction, allowing the door panel assembly 21 to move vertically.

[0110] The second end 2222 can be connected to any position on the door panel assembly 21, and this application does not limit this. Optionally, the end of the connecting part 222 is connected to the lower edge of the door panel assembly 21, or near the lower edge, thereby increasing the range of motion of the door panel assembly 21.

[0111] Please see Figure 2 and Figure 5 In some embodiments, the fixing part 221 includes a bracket 2211 and a scroll 2212. The bracket 2211 is fixedly connected to the housing 10, the scroll 2212 is rotatably connected to the bracket 2211, and one end of the connecting part 222 is fixedly connected to the scroll 2212 so that the connecting part 222 is wound or extended around the scroll 2212 as the axis.

[0112] Thus, the bracket 2211 is fixedly connected to the housing 10, the spool 2212 is rotatably connected to the bracket 2211, and the connecting part 222 is wound or extended around the spool 2212 as the axis, thereby simplifying the structure of the connecting assembly 22 and ensuring the reliability of the winding and extending activities of the connecting part 222.

[0113] Specifically, the bracket 2211 can be located at or near the edge of the housing 10 forming the opening 102 to shorten the connection path and save space. For example, the bracket 2211 is located on the top 13 of the housing 10 near the edge of the opening 102. The reel 2212 can be located below or to the side of the bracket 2211. For example, the reel 2212 is arranged horizontally alongside the bracket 2211 and is also near the edge of the housing 10 forming the opening 102. The axis of the reel 2212 can be parallel to the horizontal direction or perpendicular to the vertical direction, thereby reducing structural interference of the connection 222 when it is wound or unwound.

[0114] The first end 2221 of the connecting part 222 can be fixedly connected to the scroll 2212. When the connecting part 222 is wound around the scroll 2212 as the winding center, the first end 2221 is the starting end of the winding and is also located at the innermost side of the connecting part 222 in the winding state. The second end 2222 is the ending end of the winding. The second end 2222 can be located at the outermost side of the connecting part 222 in the winding state, or it can still be located beside the winding part of the connecting part 222 when the winding of the connecting part 222 is completed.

[0115] Please see Figure 2 and Figure 5 In some embodiments, the connecting part 222 is a coil spring 2224. In this way, the connecting part 222 can provide good elastic support and restoring force for the door panel assembly 21, so that the door panel assembly 21 can open and close normally.

[0116] Specifically, the coil spring 2224 can be wound around the roller 2212 in a relaxed state, providing a certain supporting force to the door panel assembly 21. When the second end 2222 is stretched, the coil spring 2224 unfolds, forming a certain degree of flexible support in its unfolded state, maintaining its extension and supporting the door panel assembly 21 to some extent in covering the opening 102. Furthermore, the coil spring 2224 can efficiently rebound when it needs to be unwound after being unfolded for a long time.

[0117] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the door panel assembly 21 includes a door panel 211 and a fastener 212, the fastener 212 being disposed on the side of the door panel 211 facing the bearing space 101 and fixedly connected to one end of the connecting portion 222.

[0118] Thus, by setting the fastener 212 on the side of the door panel 211 facing the bearing space 101, and fixing the fastener 212 to one end of the connecting part 222, the fastener 212 and the connecting part 222 can be covered by the door panel 211, which improves the aesthetics and also improves the space utilization.

[0119] Specifically, one side of the door panel 211 along its thickness direction faces the bearing space 101, and the other side faces the external environment of the housing 10. The fixing part 221 can be located on the side of the housing 10 facing the bearing space 101, so that the connecting component 22 can be completely covered by the door panel 211. The fixing member 212 is connected to the door panel 211 as a whole. The fixing member 212 can be fixedly connected to the door panel 211 by one of the following methods: welding, riveting, gluing, fastener connection, snap-fitting, pressure connection, etc. The fixing member 212 can also be a component integrally formed with the door panel 211.

[0120] Optionally, the shape and size of the door panel 211 match the opening 102. For example, if the opening 102 is square, the door panel 211 is a square with the same dimensions on all four sides as the opening 102.

[0121] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the fastener 212 has a first mounting hole 2121, and the end of the connecting portion 222 has a second mounting hole 2223. The first mounting hole 2121 and the second mounting hole 2223 are opposite to each other and communicate along the thickness direction of the fastener 212. The door panel assembly 21 also includes a first fastener 2123, which passes through the first mounting hole 2121 and the second mounting hole 2223 to fix the fastener 212 and the connecting portion 222.

[0122] Thus, by connecting the first mounting hole 2121 and the second mounting hole 2223 along the thickness direction of the fastener 212, and by passing the first fastener 2123 through the first mounting hole 2121 and the second mounting hole 2223, the fastener 212 and the connecting part 222 are fixedly connected, thereby improving the connection strength between the fastener 212 and the connecting part 222, and thus improving the structural reliability.

[0123] It is easy to understand that since the door panel 211 needs to be opened and closed repeatedly, the connection between the connecting part 222 and the fixing part 212 needs to withstand large and frequent forces. Therefore, using the first fastener 2123 for fastening can improve the connection strength and durability.

[0124] Specifically, the second end 2222 of the connecting portion 222 may be plate-shaped and stacked on the surface of the fixing member 212 along the thickness direction of the fixing member 212. The axial direction of the first mounting hole 2121 and the second mounting hole 2223 may be consistent with the thickness direction of the fixing member 212. The first fastener 2123 may be a screw, bolt, rivet, etc. For example, the first fastener 2123 is a bolt, and the hole walls of the first mounting hole 2121 and the second mounting hole 2223 are formed with threads corresponding to the first fastener 2123. The first fastener 2123 passes through the first mounting hole 2121 and the second mounting hole 2223 and is tightened, so that the second end 2222 of the connecting portion 222 is fixed on the fixing member 212.

[0125] Please see Figure 5 and Figure 6 In some embodiments, there are multiple first mounting holes 2121, and the lines connecting each pair of first mounting holes 2121 form a first included angle with each other. There are multiple second mounting holes 2223, and the lines connecting each pair of second mounting holes 2223 form a second included angle with each other.

[0126] Thus, with multiple first mounting holes 2121 and multiple second mounting holes 2223, the lines connecting each pair of the first mounting holes 2121 form a first angle with each other, and the lines connecting each pair of the second mounting holes 2223 also form a first angle with each other. This allows the lines connecting the first fastener 2123 through the connecting part 222 and the fastener's position to also form an angle with each other, thereby enabling the connecting part 222 to spring back more smoothly and avoid excessive curling.

[0127] Specifically, there are multiple first fasteners 2123, and each first fastener 2123 is correspondingly inserted into a set of first mounting holes 2121 and second mounting holes 2223. The number of first mounting holes 2121, second mounting holes 2223 and first fasteners 2123 can be three, four, five or more. For example, there are three first fasteners 2123, and the lines connecting each pair of the three sets of first mounting holes 2121 and second mounting holes 2223 form a triangle.

[0128] Please see Figure 2 , Figure 3 and Figure 7 In some embodiments, the analyzer 100 further includes a guide device 40 extending in a direction from a first position to a second position. The guide device 40 includes a first guide member 41 connected to the housing 10 and a second guide member 42 connected to the door panel assembly 21. The second guide member 42 is movably connected to the first guide member 41 along the extension direction of the guide device 40.

[0129] Thus, by extending the guide device 40 directionally from the first position to the second position, the first guide member 41 is connected to the housing 10, and the second guide member 42 is connected to the door panel assembly 21. The second guide member 42 is movably connected to the first guide member 41 along the extension direction of the guide device 40, thereby restricting the movement of the door panel assembly 21 relative to the housing 10 in the direction from the first position to the second position, and keeping the door panel assembly 21 stable when opening and closing.

[0130] Specifically, the first guide member 41 and the second guide member 42 may include, but are not limited to, slide rails, slide grooves, sliders 422, etc. The first guide member 41 may be fixedly connected to the housing 10, and the second guide member 42 may be fixedly connected to the door panel 211. The first guide member 41 and the second guide member 42 slide relative to each other to allow the door panel 211 to move relative to the housing 10. The first guide member 41 and the second guide member 42 may extend along a straight path, or along a curved path, or along a combination of straight and curved paths.

[0131] Accordingly, the first guide 41 and the second guide 42 extend along a straight path to restrict the door panel assembly 21 from moving in a straight line relative to the housing 10, and the second guide 42 extends along a curved path to restrict the door panel assembly 21 from moving along a curved path relative to the housing 10.

[0132] Taking the opening 102 formed on the front side of the housing 10 as an example, the direction from the first position to the second position is the first direction A, which can form an angle greater than or equal to 0° and less than 90° with the up and down direction. The door panel assembly 21 covers the opening 102 in the first position, and moves upward relative to the housing 10 from the first position to the second position, thereby opening the opening 102; conversely, the door panel assembly 21 opens the opening 102 in the second position, and moves downward relative to the housing 10 from the second position to the first position, thereby closing the opening 102.

[0133] The second guide member 42 can be set on the side of the door panel 211 facing the bearing space 101, and the first guide member 41 is set in the bearing space 101. The door panel 211 can also cover the wire device when covering the opening 102.

[0134] Please see Figure 2 , Figure 5 and Figure 7 In some embodiments, the analyzer 100 includes a mounting frame 43 for supporting the guide device 40. The mounting frame 43 is erected in the bearing space 101 and fixedly connected to at least one side wall 15 of the housing 10. A first guide member 41 is fixedly mounted on the side surface of the mounting frame 43 facing the door panel assembly 21.

[0135] Thus, the first guide member 41 is fixedly installed on the side surface of the fixed frame 43 facing the door panel assembly 21 by the fixed frame 43 erected in the bearing space 101 and fixedly connected to at least one side wall 15 of the housing 10, thereby stably supporting the first guide member 41 and the second guide member 42, which is beneficial to the stability of the first guide member 41 and the second guide member 42 in relative movement.

[0136] Specifically, the fixing frame 43 can be in the form of a column. The fixing frame 43 can be a single part or it can be formed by combining several sub-parts such as plates, rods, and beams.

[0137] Taking the opening 102 formed on the front side of the housing 10 as an example, the fixing frame 43 can be connected to the bottom 14 of the housing 10 and one of the side walls 15 on the left and right sides. The door panel assembly 21 can be located on the front side of the second guide 42, and the fixing frame 43 can be supported on the rear side of the first guide 41, thereby providing certain support and compression for the cooperation between the first guide 41 and the second guide 42 in at least three directions, and improving the stability of the relative movement of the first guide 41 and the second guide 42 in the vertical direction.

[0138] Optionally, the mounting bracket 43 may also abut or connect with other components in the load-bearing space 101 to improve stability.

[0139] Optionally, the first guide member 41 can be connected to the fixing frame 43 by at least one of the following methods: welding, riveting, bonding, connection with the fastener 212, snap-fit ​​connection, pressure fitting, etc. The first guide member 41 is disposed on the side surface of the fixing frame 43 facing the door panel assembly 21.

[0140] Combination Figure 2 and Figure 3 In some embodiments, the direction in which the door panel 211 moves from the first position to the second position is the first direction A, and the first direction A forms an angle greater than 0° and less than 90° with the up and down direction. The surface of the fixing frame 43 connected to the first guide member 41 also forms an angle with the up and down direction accordingly. That is to say, the surface of the fixing frame 43 connected to the second guide member 42 is an inclined surface.

[0141] Please see Figure 2 , Figure 4 and Figure 6 In some embodiments, the door panel assembly 21 includes a door panel 211 and a connecting block 213 fixedly connected to the second guide member 42. The connecting block 213 is disposed on the side of the door panel 211 facing the bearing space 101. The first guide member 41 and the second guide member 42 extend linearly along the height direction of the door panel 211.

[0142] Thus, the connecting block 213 is fixedly connected to the second guide member 42. The connecting block 213 is located on the side of the door panel 211 facing the bearing space 101. The first guide member 41 and the second guide member 42 extend in a straight line along the height direction of the door panel 211, thereby making the second guide member 42 and the door panel 211 spaced apart along the thickness direction of the door panel 211, avoiding the risk of structural interference when the door panel 211 moves relative to the housing 10.

[0143] Specifically, the door panel 211 is fixedly connected to the connecting block 213, which can be achieved through welding, riveting, bonding, fastening with fastener 212, or snap-fit ​​connection, or it can be integrally formed into a single unit. One side of the door panel 211 along its thickness direction faces the bearing space 101, and the other side faces the external environment of the housing 10. The connecting block 213 protrudes along the thickness direction of the door panel 211 towards the bearing space 101, causing the second guide member 42 to be spaced apart from the door panel 211 along its thickness direction. The height direction of the door panel 211 is also the vertical direction as shown in the figure, and the height direction of the door panel 211 forms an angle of approximately 90° with its thickness direction.

[0144] The first guide member 41 and the second guide member 42 extend along the height direction of the door panel 211, causing the door panel 211 to move straight up or down in a straight line along its own height direction. This results in a shorter movement path for the door panel assembly 21 between the first position and the second position.

[0145] Please see Figure 7 In some embodiments, the first guide member 41 includes a first slide groove 411, and the second guide member 42 includes a second slide groove 421 and a slider 422. The openings of the first slide groove 411 and the second slide groove 421 are opposite to each other and spaced apart. The slider 422 is clamped in the first slide groove 411 and the second slide groove 421 and slides and engages with the first slide groove 411 and the second slide groove 421 respectively.

[0146] Thus, the first slide groove 411 and the second slide groove 421 are spaced apart with their openings facing each other. The slider 422 is clamped in the first slide groove 411 and the second slide groove 421 and slides into the first slide groove 411 and the second slide groove 421 respectively, thereby increasing the sliding stroke of the door panel 211 under the condition that the lengths of the first slide groove 411, the second slide groove 421 and the slider 422 are limited.

[0147] Specifically, the first groove 411 is recessed on the surface of the first guide member 41 facing the second guide member 42, and the second groove 421 is recessed on the surface of the second guide member 42 facing the first guide member 41. The directions in which the first groove 411 and the second groove 421 are recessed are opposite to each other. The surfaces of the first groove 411 and the second groove 421 that form the groove openings can also contact each other, and the bottom surfaces of the first groove 411 and the second groove 421 are spaced apart from each other.

[0148] The inner contour boundaries of the cross-sections of the first groove 411 and the second groove 421 of the slider 422 are respectively matched with half of the cross-sectional shape of the slider 422. The slider 422 can slide in the first groove 411 or in the second groove 421.

[0149] The peripheral side of the slider 422 and the groove walls of the first groove 411 and the second groove 421 can form a mutually engaging structure. For example, a groove 4221 is formed on the peripheral side of the slider 422, and the groove walls of the first groove 411 and the second groove 421 are both formed with ribs 4111, with the ribs 4111 partially or completely extending into the groove 4221. Alternatively, a protrusion 4222 is formed on the slider 422, and the groove walls of the second groove 421 and the second groove 421 form a limiting groove 4112, in which the protrusion 4222 is wholly or partially accommodated. In this embodiment, the ribs 4111, the grooves 4221, the limiting grooves 4112, and the protrusions 4222 all extend along the first direction A.

[0150] In some embodiments, when the user pushes the door panel 211 from the first position to the second position, the slider 422 slides in the first slide groove 411, and the second guide 42 moves upward relative to the first slide groove 411 until the slider 422 is close to disengaging from the first slide groove 411. At this time, the relative position of the slider 422 and the first guide 41 can remain unchanged, and the second slide groove 421 continues to move upward relative to the slider 422 until the slider 422 is close to disengaging from the second slide groove 421.

[0151] Please see Figure 4 , Figure 6 and Figure 7 In some embodiments, the side surface of the second guide 42 facing away from the slider 422 cooperates with the connecting block 213 to fix the connecting block 213 to the second guide 42.

[0152] Thus, the second guide 42 is fixedly connected to the connecting block 213 on the side surface opposite to the slider 422, thereby making the structure compact and reducing structural interference.

[0153] Specifically, the second guide member 42 has a third mounting hole 423 on its surface opposite to the slider 422. The third mounting hole 423 can be a blind hole or a through hole. The surface of the connecting block 213 facing the second guide member 42 can fit tightly against the second guide member 42. The second guide member 42 and the connecting block 213 can be fixedly connected by fasteners 212 passing through the third mounting hole 423.

[0154] Please see Figure 2 and Figure 5In some embodiments, there are two guide devices 40, which are respectively arranged on both sides of the opening 102 along the width direction of the analyzer 100.

[0155] Thus, by having two guide devices 40 positioned on both sides of the opening 102 along the width direction of the analyzer 100, the door panel assembly 21 can be limited and supported by the guide devices 40 on both sides of the width direction, thereby improving the balance and stability of the door panel assembly 21 relative to the housing 10.

[0156] Specifically, the direction from the top 13 to the bottom 14 of the housing 10 is defined as the top-to-bottom direction, which is also the height direction of the analyzer 100. Taking the opening 102 formed on the front side of the housing 10 as an example, the width direction of the analyzer 100 is also the left-right direction as shown in the figure. A fixing frame 43 is provided on the left side of the opening 102. A set of cooperating first guide members 41 and second guide members 42 are provided on the fixing frame 43. The second guide member 42 is fixedly connected to a connecting block 213 near the left edge of the door panel 211. Another fixing frame 43 is provided on the right side of the opening 102. A set of cooperating first guide members 41 and second guide members 42 are also provided on the fixing frame 43. The second guide member 42 on the right side is fixedly connected to a connecting block 213 near the right edge of the door panel 211.

[0157] Please see Figure 1 and Figure 2 In some embodiments, the locking device 30 includes an interaction component 31 and a locking structure 32 connected to the interaction component 31. The interaction component 31 is at least partially exposed on the outer surface of the housing 10. The locking structure 32 is detachably connected to the door panel assembly 21 and is configured to separate from the door panel assembly 21 when the interaction component 31 is subjected to a force.

[0158] Thus, by having the interactive component 31 at least partially exposed on the outer surface of the housing 10, the user can easily interact with the interactive component 31 and apply force. When the locking structure 32 is connected to the door panel assembly 21, it can lock the door panel assembly 21. When the user applies force to the interactive component 31, the locking structure 32 separates from the door panel assembly 21, that is, the door panel assembly 21 is unlocked. At this time, the door panel assembly 21 can move relative to the housing 10, thereby making the user operation simpler and more convenient.

[0159] Specifically, the interactive component 31 may include, but is not limited to, buttons 311, knobs, sliders, levers, touchscreens, etc. The locking structure 32 can be detachably connected to the door panel assembly 21 by means of snap-fit, adhesive, magnetic adsorption, etc.

[0160] Please see Figure 2 and Figure 10In some embodiments, the locking device 30 includes an elastic member 33, which connects the interaction member 31 and the locking structure 32. The elastic member 33 is used to engage the locking structure 32 with the door panel assembly 21 when the locking structure 32 is subjected to the force of the door panel assembly 21, and to push the interaction member 31 to reset when the locking structure 32 is separated from the door panel assembly 21.

[0161] Thus, when the locking structure 32 is subjected to the force of the door panel assembly 21, the elastic component 33 drives the locking structure 32 to engage with the door panel assembly 21, and pushes the interactive component 31 to reset when the locking structure 32 is separated from the door panel assembly 21, thereby realizing the automatic locking of the door panel assembly 21 by the locking device 30 and the automatic reset of the locking device 30 when the door panel assembly 21 is unlocked, which facilitates the next locking operation.

[0162] Specifically, the elastic component 33 can be, but is not limited to, a spring 331, a torsion spring, a spring sheet, an elastic washer, etc. The elastic component 33 connects the interaction component 31 and the locking structure 32. When either or both of the interaction component 31 and the locking structure 32 are subjected to external forces, the elastic component 33 can produce elastic deformation, or the degree and direction of deformation can change according to the degree of indirect force.

[0163] Please see Figure 8 and Figure 10 In some embodiments, the interactive component 31 is a button 311, the elastic component 33 is a spring 331, the button 311 and the spring 331 are stacked along the axial direction of the spring 331, and the axial direction of the spring 331 forms an angle with the direction from the first position to the second position.

[0164] It is easy to understand that the axial direction of spring 331 is the direction of compression or extension when spring 331 elastically deforms. This application defines the direction of movement of door panel assembly 21 relative to housing 10 as first direction A. First direction A includes the direction from first position to second position and the direction from second position to first position. The axial direction of spring 331 also forms an angle with first direction A.

[0165] Thus, by stacking the button 311 and the spring 331 along the axial direction of the spring 331, the user can push the spring 331 to produce elastic deformation when pressing the button 311, making the operation more convenient. Furthermore, the axial direction of the spring 331 forms an angle with the direction from the first position to the second position. In other words, the direction of elastic deformation of the spring 331 forms an angle with the direction of movement of the door panel assembly 21. This allows the door panel assembly 21 to be effectively locked and unlocked even when the deformation range of the spring 331 is small, saving torque.

[0166] Specifically, one axial end of the spring 331 abuts against the button 311, and the side of the button 311 facing away from the spring 331 protrudes outside the housing 10. When the user presses the button 311, the spring 331 is compressed, and when the user removes the pressure on the button 311, the spring 331 returns to its original shape and extends.

[0167] Optionally, the axial direction of the spring 331 may be perpendicular to the first direction A.

[0168] Please see Figure 5 and Figure 8 In some embodiments, the door panel assembly 21 includes a door panel 211 and a limiting structure 214. The limiting structure 214 is located at the end of the door panel 211 in the direction from the second position to the first position. The limiting structure 214 is used to engage with the locking structure 32 so that the door panel assembly 21 is fixedly connected to the locking device 30 in the first position.

[0169] Thus, by engaging the limiting structure 214 with the locking structure 32 at the end of the door panel 211 in the direction from the second position to the first position, the door panel assembly 21 is fixedly connected to the locking device 30 in the first position, thereby improving the locking effect of the locking device 30 on the door panel assembly 21 and ensuring controllable unlocking.

[0170] Specifically, the direction from the second position to the first position can be a downward angle, and the limiting structure 214 is located at the lower edge of the door panel 211. The limiting structure 214 may include, but is not limited to, ribs, protrusions, hooks, clips, and locking strips. The locking structure 32 is provided on the edge of the housing 10 that forms the opening 102, and is located on the side edge of the housing 10 corresponding to the edge of the door panel 211 where the limiting structure 214 is located.

[0171] Please see Figure 8 , Figure 10 and Figure 12 In some embodiments, the housing 10 includes a first frame 16 surrounding the opening 102, the locking device 30 includes a mounting box 34 and a lock cylinder 35 at least partially disposed within the mounting box 34, the mounting box 34 and the first frame 16 together defining a mounting space 341, an elastic member 33 is sleeved on the lock cylinder 35, and the same end of the elastic member 33 and the lock cylinder 35 is connected to an interaction member 31 in the axial direction, the interaction member 31 being disposed on the first frame 16.

[0172] Thus, the lock cylinder 35 is at least partially disposed within the mounting box 34, the elastic member 33 is sleeved on the lock cylinder 35, and the same end of the elastic member 33 and the lock cylinder 35 in the axial direction is connected to the interaction member 31. The interaction member 31 is disposed on the first frame 16, so that the interaction member 31 can cooperate with the locking device 30 and the limiting structure 214 to lock and unlock the door panel assembly 21.

[0173] Specifically, when the door panel assembly 21 closes the opening 102, the edge of the door panel 211 mates, snaps, fits, or engages with the first frame 16. The first frame 16 has a wider strip on its lower side to facilitate the first frame 16 covering the locking device 30. The mounting box 34 is open on one side facing the frame, and the first frame 16 covers the open side of the mounting box 34, together forming the mounting space 341. The interaction component 31 is located in the area of ​​the mounting space 341 enclosed by the first frame 16.

[0174] The mounting box 34 can be a hollow polyhedron of square, circular, triangular, polygonal, or other irregular shapes. For example, the mounting box 34 is a square box.

[0175] The lock cylinder 35 may be cylindrical and may be fixedly connected to the interaction component 31. The end of the elastic component 33 may abut against or be fixedly connected to the interaction component 31.

[0176] Optionally, the door panel 211 includes a main body panel 2111 and a second frame 2112 surrounding the main body panel 2111, and a connecting block 213 and / or a fastener 212 may be disposed on the main body panel 2111. When the door panel assembly 21 closes the opening 102, the first frame 16 and the second frame 2112 may be stacked along the thickness direction of the main body panel 2111.

[0177] The second frame 2112 has a first edge 2113 and a second edge 2114 along its width. The first edge 2113 is fixedly connected to the edge of the main body plate 2111, and the second edge 2114 is located inside the first edge 2113. The second frame 2112 extends from the edge of the main body plate 2111 toward the interior of the housing 10 and the center of the main body plate 2111. The second frame 2112 can form an angle with both the surface direction and the thickness direction of the main body plate 2111. The surface direction of the main body plate 2111 is approximately parallel to the first direction A.

[0178] The first frame 16 has a third edge 163 and a fourth edge 164 along its own width direction. When the opening 102 is closed, the third edge 163 can coincide with the second edge 2114. The first frame 16 extends outward from the second edge 2114, and the fourth edge 164 can extend beyond the outer boundary of the second frame 2112 and the main body plate 2111 along the plate surface direction of the main body plate 2111.

[0179] In other embodiments, the door panel 211 is an integral structure, and / or the housing 10 is an integral structure. The limiting structure 214 is disposed on the edge of the door panel 211, and the locking structure 32 is disposed on the edge of the housing 10 surrounding the opening 102 and is located on the same side of the opening 102 as the limiting structure 214, so that when the door panel assembly 21 moves along the first direction A and closes the opening 102, the limiting structure 214 can engage with the locking structure 32.

[0180] Please see Figure 5 , Figure 8 and Figure 12 In some embodiments, the limiting structure 214 includes a limiting piece 2141 that extends and bends from the edge of the door panel 211 toward the mounting box 34.

[0181] The locking structure 32 includes a connecting end 322 and a locking end 323. The connecting end 322 is connected to the end of the lock cylinder 35 away from the interactive component 31 and is disposed on the side wall 15 of the mounting box 34 away from the mounting space 341. The locking end 323 is connected to the connecting end 322 and bends toward the limiting piece 2141.

[0182] The locking end 323 is used to engage with the limiting piece 2141 to lock the door panel assembly 21, and to disengage from the limiting piece 2141 as the elastic member 33 moves with the connecting end 322 when it is deformed by pressure, so as to unlock the door panel assembly 21.

[0183] Thus, by bending the limiting piece 2141 toward the mounting box 34 and the locking end 323 toward the edge of the first frame 16, the limiting piece 2141 and the locking end 323 are effectively engaged, ensuring the reliability of the locking device 30 in locking the door panel assembly 21. Furthermore, when the elastic component 33 is compressed, it can move the locking structure 32 to disengage from the limiting piece 2141, achieving one-button unlocking for user convenience.

[0184] Specifically, the mounting box 34 includes a bottom wall opposite to the first frame 16, and the connecting end 322 of the locking structure 32 is located on the side of the bottom wall away from the mounting space 341. The bottom wall may have a through hole, which may be axially aligned with the lock cylinder 35 inside the mounting box 34. The connecting end 322 may be an annular structure, and the center of the connecting end 322 is axially aligned with the through hole. The through hole may be located at the center of the bottom wall. The locking device 30 also includes a second fastener 39, which may pass sequentially through the connecting end 322, the through hole, and the lock cylinder 35 to fix the connecting end 322 to the lock cylinder 35. The second fastener 39 may be a bolt, screw, rivet, etc.

[0185] The limiting piece 2141 may be located on the second frame 2112. For example, the limiting piece 2141 extends a certain length from the second edge 2114 along the width direction of the second frame 2112, then bends towards the mounting box 34, and protrudes again at its end along the width direction of the second frame 2112, forming a hook-like structure. When the opening 102 is closed, the second edge 2114 coincides with the third edge 163 of the first frame 16, and the limiting piece 2141 is also located at the edge of the first frame 16.

[0186] The locking structure 32 extends outward from the middle of the bottom wall and bends towards the second edge 2114 along the bottom wall in the direction of the first frame 16 on the outside of the mounting box 34. The locking end 323 is the end of the extension of the locking structure 32. The direction opposite to the bottom wall of the mounting box 34 and the first frame 16 forms an angle with the first direction A. The locking end 323 engages with the hook-shaped structure at the end of the limiting piece 2141, restricting the movement of the door panel assembly 21 along the first direction A, that is, locking the door panel assembly 21.

[0187] The locking device 30 locks the door panel assembly 21 as follows: when the opening 102 needs to be closed, the user pushes the door panel assembly 21 closer to the locking device 30 along the first direction A. The limiting piece 2141 contacts the upper surface of the locking end 323 along the first direction A. The user continues to apply pressure to the door panel assembly 21, and the limiting piece 2141 continues to apply pressure to the locking end 323 along the first direction A until the end of the limiting piece 2141 can press past the locking end 323 and abut against the back surface of the locking end 323 along the first direction A. The limiting piece 2141 and the locking end 323 interlock and restrict each other's movement along the first direction A, thereby locking the door panel assembly 21.

[0188] The process of the locking device 30 unlocking the door panel assembly 21 can be as follows: when the door panel assembly 21 is locked, when the user presses the interactive component 31, the interactive component 31 transmits force to the elastic component 33 and the lock cylinder 35, causing the elastic component 33 to compress and deform, and the lock cylinder 35 to move axially, pushing the locking structure 32 to move axially along the lock cylinder 35, so that the locking end 323 disengages from the limiting piece 2141, thereby unlocking the door panel assembly 21. After the door panel assembly 21 is unlocked, the user can remove the force, and the elastic component 33 rebounds and drives the interactive component 31, the lock cylinder 35, and the locking structure 32 to reset.

[0189] Optionally, a gasket 38 is provided between the connecting end 322 and the bottom wall. The gasket 38 can abut against the bottom wall and the connecting end 322 respectively when the elastic member 33 does not undergo elastic deformation, and can separate from the bottom wall and / or the connecting end 322 when the elastic member 33 undergoes elastic deformation and the lock cylinder 35 and the connecting end 322 move away from the bottom wall.

[0190] Please see Figures 9-12In some embodiments, the locking device 30 further includes a lock housing 36 and a lock cylinder 37 sequentially sleeved outside the lock cylinder 35. Both the lock housing 36 and the lock cylinder 37 are accommodated in the installation space 341. The lock cylinder 37 forms openings at both ends in the axial direction. The lock housing 36 includes an end face 361 and a peripheral face 362. The end face 361 is fixedly connected to the frame and covers one of the openings of the lock cylinder 37. The peripheral face 362 surrounds the elastic member 33 and the lock cylinder 35.

[0191] Thus, the lock housing 36 and the lock cylinder 37 are sequentially fitted around the lock cylinder 35 and are both located in the installation space 341. The end face 361 of the lock housing 36 is fixedly connected to the frame and covers one of the openings of the lock cylinder 37. The peripheral surface 362 of the lock housing 36 surrounds the elastic member 33 and the lock cylinder 35, thereby making the interior of the locking device 30 more compact, which is conducive to unlocking and locking the door panel assembly 21 within the preferred deformation range of the elastic member 33.

[0192] Specifically, the lock cylinder 37 can be fixedly connected to the inner wall of the mounting box 34, for example, the lock cylinder 37 and the mounting box 34 are integrally formed. The lock cylinder 37 is hollow inside and has a fourth mounting hole 342, which facilitates the placement of the lock cylinder 35 and restricts the position of the lock cylinder 35 within the mounting space 341. The peripheral surface 362 of the lock cylinder 35, the elastic member 33, and the lock shell 36 are all located in the fourth mounting hole 342.

[0193] The lock cylinder 35, the elastic element 33, the lock housing 36, and the lock cylinder 37 are sequentially fitted together, with all four having the same axial direction. When the elastic element 33 does not undergo elastic deformation, one end of the elastic element 33 and the lock cylinder 35 along the axial direction can be flush with the end face 361 of the lock housing 36, and the other end can abut against the bottom wall of the mounting box 34. For ease of explanation, this application defines the direction along the axial direction of the lock housing 36 from the end face 361 to the bottom wall of the mounting box 34 as the second direction B.

[0194] Please see Figure 8 and Figure 12 In some embodiments, the end face 361 and the first frame 16 together form a receiving hole 3611. The receiving hole 3611 penetrates the frame and the end face 361 along its own axis. The receiving hole 3611 is used to accommodate the interactive component 31. The elastic component 33 and the lock cylinder 35 pass through the receiving hole 3611 and are connected to the interactive component 31.

[0195] The interactive component 31 is configured to extend at least partially into the receiving hole 3611 as the elastic component 33 undergoes elastic deformation, and is configured to at least partially exit the receiving hole 3611 and be exposed outside the frame as the elastic component 33 recovers its elastic deformation.

[0196] Thus, the elastic member 33 and the lock cylinder 35 pass through the receiving hole 3611 and are connected to the interaction member 31. The interaction member 31 is at least partially inserted into the receiving hole 3611 as the elastic member 33 deforms, and at least partially withdraws from the receiving hole 3611 and is exposed outside the frame as the elastic member 33 returns to its original shape. This makes the different states of the interaction member 31 more intuitive and easier for users to operate. It also makes the structure more compact and reduces the space occupied.

[0197] Specifically, the ends of the elastic member 33 and the lock cylinder 35 on the same side as the end face 361 can partially extend into the receiving hole 3611, and the lock cylinder 35 can be connected to the interaction member 31 in the receiving hole 3611, with the elastic member 33 abutting against the interaction member 31. When the elastic member 33 does not undergo elastic deformation, the interaction member 31 is wholly or partially exposed outside the receiving hole 3611. When the user applies pressure to the interaction member 31, the elastic member 33 is compressed by elastic deformation, the lock cylinder 35 moves along the second direction B, and the interaction member 31 also enters the receiving hole 3611 wholly or partially along the second direction B. When the user removes the force applied to the interaction member 31, the elastic member 33 returns to its elastic deformation, and the interaction member 31 exits the receiving hole 3611 in the opposite direction of the second direction B.

[0198] Please see Figures 9-11 In some embodiments, the two ends of the lock cylinder 37 in the axial direction abut against the end face 361 of the lock housing 36 and the wall surface of the mounting box 34, respectively. The circumferential surface 362 forms a threaded structure 3621 on the side away from the elastic member 33. The threaded structure 3621 cooperates with the lock cylinder 37 to fix the lock cylinder 37 to the lock housing 36.

[0199] Thus, the two ends of the lock cylinder 37 abut against the end face 361 of the lock housing 36 and the wall of the mounting box 34 respectively, and the circumferential surface 362 forms a threaded structure 3621 on the side away from the elastic member 33. The threaded structure 3621 cooperates with the lock cylinder 37 to fix the lock cylinder 37 to the lock housing 36, thereby making the internal structure of the locking device 30 compact and the connection stable.

[0200] Specifically, the inner circumferential surface 362 of the lock cylinder 37 may also be threaded to cooperate with the threaded structure 3621 on the lock housing 36, so that the lock housing 36 and the lock cylinder 37 are fixedly connected.
