[0029] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0030] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the usual meanings understood by people with ordinary skills in the field to which this disclosure belongs. The "first", "second" and similar words used in one or more embodiments of this specification do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0031] To facilitate understanding of the hatch assembly provided in the embodiment of the present application, its application scenario is first described. The hatch assembly provided in the embodiment of the present application is a component of an instrument, and can be particularly applied to a gene sequencer, such as a gene sequencer.

[0032] Gene sequencers typically have a hatch to protect the delicate components and samples inside. Specifically, when the hatch is open, operations such as chip loading, reagent cartridge removal, and maintenance and cleaning can be performed. During operation or after a task is completed, the hatch should be closed to prevent contamination of samples and damage to delicate components.

[0033] For instruments, human-computer interaction performance is a key factor in their overall performance evaluation. As one of the components with which users interact most frequently with the instrument, the convenience of the hatch is particularly important. Therefore, to enhance the convenience of instrumentation, an increasing number of instruments are adopting automatic hatches.

[0034] An automatic hatch typically consists of a motion assembly that enables the hatch's movement and a power assembly that powers it. Prior art automatic hatch solutions used in some gene sequencers feature motion and power assemblies that are separately fixed to the instrument's housing. However, the large overall size of the instrument housing inevitably leads to significant local flatness errors, which can easily increase the kinematic coordination errors between the power assembly and motion assembly, leading to the automatic hatch becoming stuck during operation.

[0035] To this end, the present invention provides a hatch assembly to improve the motion coordination accuracy between the power assembly and the motion assembly, thereby improving the stability of the automatic hatch operation. The hatch assembly provided by the present invention is described in detail below with reference to the accompanying drawings.

[0036] refer to Figure 1 , Figure 1 An overall schematic diagram of the hatch assembly provided in an embodiment of the present application. The hatch assembly provided in an embodiment of the present application includes a door panel assembly 2, a motion assembly, a sliding member (refer to the position of the slider 45 and the guide block 2) and a power assembly. Among them, the motion assembly includes a base 1, a sliding structure arranged on the base 1 (refer to the position of the guide rail 11 and the linear slide rail 42) and a support plate 3 fixedly connected to the base 1. The base 1 is used to be fixed as a whole to the hatch portion of the gene sequencer, and is used to install other components such as the door panel assembly 2 and the support plate 3. The door panel assembly 2 slides with the base 1, and the door panel assembly 2 slides relative to the base 1, which can close the hatch of the gene sequencer or open the hatch of the gene sequencer. Specifically, the base 1 can be frame-shaped as a whole, and guide rails 11 are provided on both sides of the hatch of the gene sequencer.

[0037] The sliding member is slidably connected to the sliding structure, so that the sliding member can slide relative to the sliding structure. Since the sliding structure is disposed on the base 1 , the sliding member sliding relative to the sliding structure means that the sliding member slides relative to the base 1 .

[0038] The door panel assembly 2 may include one door panel or multiple door panels. Figure 2 ,in Figure 2 The door panel assembly 2 shown includes only one door panel. Figure 1 The door panel assembly 2 shown in FIG. comprises two door panels. The door panel assembly 2 is connected to a sliding member, and the sliding member and the sliding structure slidably engage with each other via the sliding member. Once the sliding member and the sliding structure are slidably engaged, the door panel assembly 2 can slide relative to the base 1, thereby opening and closing the hatch of the gene sequencer.

[0039] As an optional embodiment, Figure 1 Taking the two door panels shown as an example, the sliding structure includes a guide rail 11, and the sliding member includes a guide block 2, which slides with the guide rail 11. Specifically, guide blocks 21 are provided on both sides of the door panel, and the guide rail 21 is provided on the base 1. The guide blocks 21 are slidably connected to the guide rail 11, that is, the sliding connection between the door panel assembly 2 and the base 1 is realized. When there are two door panels, the two door panels can be hingedly connected. At this time, the number of guide blocks 21 can be set to two pairs, one pair of guide blocks 21 is provided on both sides of one door panel, and the other pair of guide blocks 21 can be provided at the hinged connection between the two door panels. For example, Figure 2In the case where the door panel assembly 2 shown includes only one door panel, only a pair of guide blocks 21 may be provided, one on each side of the door panel.

[0040] Optional, such as Figure 1 The guide rail 11 of the illustrated base 1 comprises a first guide segment and a second guide segment. The first guide segment 111 is located behind the second guide segment 112 (the specific front-to-back orientation is indicated in the figure). The first guide segment 111 extends in a straight line, while the second guide segment 112 extends along an arc. The second guide segment 112 extends gradually forward from its connection with the first guide segment 111 toward the hatch area. This arrangement of the guide rail 11 allows the door panel assembly 2 to be retracted into the interior of the gene sequencer, close to the outer casing, thereby better utilizing the space within the gene sequencer.

[0041] In Xiang Ru Figure 1 When sliding forward as indicated by the middle arrow, the door panel, guided by the guide rail 11, slides to a position where it can block the opening of the gene sequencer until the door panel assembly 2 completely closes the gene sequencer's hatch. To open the hatch of the gene sequencer, the door panel assembly 2 slides backward along the guide rail 11 as indicated by the arrow, gradually retracting into the interior of the gene sequencer and opening the hatch.

[0042] To drive the hatch door open or closed, the hatch assembly also includes a power assembly, which is fixedly connected to the base 1 and in transmission connection with the door panel assembly 2. The power assembly can drive the door panel assembly 2 to slide relative to the sliding structure via a sliding member, thereby causing the door panel assembly 2 to slide relative to the base 1, thereby switching the hatch of the gene sequencer between a closed state and an open state, that is, realizing automatic opening and closing of the hatch of the gene sequencer.

[0043] When fixing the power assembly, the power assembly is fixed on the support plate 3. For details, please refer to Figure 1 The support plate 3 can be located on one side of the base 1 and has a certain width to ensure that there is enough space for fixing the power assembly. The power assembly is fixed on the support plate 3.

[0044] By providing the support plate 3, it is equivalent to the power assembly being directly fixedly connected to the motion assembly through the support plate 3. The support plate 3 itself is relatively small in size, has high rigidity, and high precision, and has a good positioning effect on the power assembly. Moreover, when the door assembly is specifically installed on the gene sequencer, the assembly positions of the power assembly, the motion assembly, and the door panel can be debugged in advance, and then the door assembly as a whole can be installed on the gene sequencer. Compared with the traditional solution in which the power assembly and the motion assembly are respectively fixed to the housing of the gene sequencer, the installation precision is easier to control and better stability is easy to obtain. After the door assembly is installed as a whole on the gene sequencer, the motion assembly is partially fixedly connected to the overall panel of the gene sequencer, and the power assembly is directly fixedly connected to the motion assembly through the support plate 3. This can also reduce the risk of excessive assembly errors between the power assembly and the motion assembly or the door panel assembly 2 due to deformation of the installation panel of the gene sequencer, thereby improving the stability of the overall door assembly during subsequent use.

[0045] In the above technical solution, by setting a support plate 3 fixedly connected to the motion component and fixing the power component to the support plate 3, the support plate 3 can be used to more accurately fix the power component to the correct position, and it is easy to control the relative position deviation between the power component and the motion component and the door panel component 2, thereby improving the assembly accuracy of the power component and the cabin door component, thereby improving the stability of the automatic cabin door operation.

[0046] As an optional embodiment, when the power assembly is fixed to the support plate 3, threaded fasteners can be used for fixing. The method of fixing with threaded fasteners has the characteristics of simple assembly and convenient disassembly. In order to achieve a better positioning effect when using threaded fasteners to fix the power assembly, the threaded fasteners can be countersunk bolts or countersunk screws, and countersunk holes are provided on the support plate 3. When fixing the power assembly, the countersunk bolts or countersunk screws are passed through the countersunk holes and the power assembly is fixed to the support plate 3. The countersunk bolts or countersunk screws cooperate with the countersunk holes to achieve a better positioning effect, thereby improving the position accuracy of the power assembly, reducing the risk of the door panel assembly 2 sliding and getting stuck due to excessive position error between the power assembly and the door panel assembly 2, and thereby improving the operating stability of the cabin door assembly.

[0047] It should be understood that when configuring the power assembly, the power assembly may include power components such as various electric and pneumatic motors, hydraulic pumps, and transmission components such as gears, screws, and hydraulic push rods. Furthermore, when configuring the power assembly to be in transmission connection with the door panel assembly 2, the power assembly may be configured to directly drive the door panel to slide, or some transmission structure may be configured.

[0048] As an optional embodiment, the power assembly and the sliding member can be connected through a flexible connection member 41. Figure 1, one end of the flexible connector 41 is connected to the power assembly, and the other end of the flexible connector 41 is connected to the sliding member, so that the power assembly can drive the sliding member to slide relative to the sliding structure through the flexible connector 41, thereby driving the door panel assembly 2 to slide. The flexible connector 41 used in this embodiment not only has a structural strength that meets the transmission requirements, but also has a certain flexibility, so that when the flexible connector 41 transmits the driving force, it can absorb a certain position error in the assembly between the screw nut 44 and the sliding member. By setting the flexible connector 41 to connect and drive the door panel assembly 2, it can play a role in absorbing the assembly error between the power assembly and the door panel assembly 2, thereby further reducing the risk of jamming during the automatic opening or closing of the cabin door, and improving the operational stability of the cabin door assembly.

[0049] Optionally, the specific form of the flexible connector 41 can be as follows: Figure 1 As shown, the flexible connector 41 is entirely a metal plate. This metal plate has a certain structural strength and can transmit driving force. The metal plate is thin and can withstand a certain amount of elastic deformation, thereby serving as a flexible connection. Of course, in other possible embodiments, the flexible connector 41 can also be made of other materials, or the flexible connector 41 can also be a composite material or component, provided that the strength requirements for transmission and the flexibility requirements for absorbing assembly errors are met.

[0050] As an optional implementation, continue to refer to Figure 1 When the power assembly is specifically set up, the power assembly may include a drive motor 42, a screw rod 43 and a screw nut 44. Among them, the drive motor 42 is fixed to the support plate 3 and can serve as a power source for driving the door panel assembly 2 to slide. The screw rod 43 can be set along the front and rear directions, and the screw rod 43 is fixedly connected to the output shaft of the drive motor 42, so that the drive motor 42 can drive the screw rod 43 to rotate clockwise or counterclockwise. The screw nut 44 is threadedly connected to the screw rod 43, so that when the screw rod 43 rotates under the drive of the drive motor 42, the screw nut 44 can move back and forth. The screw nut 44 is connected to the sliding member through the flexible transmission member 41. When the screw nut 44 moves back and forth, it can drive the sliding member to slide through the flexible transmission member 41, thereby driving the door panel assembly 2 to slide back and forth, thereby realizing the opening or closing of the cabin door.

[0051] In the process of using the screw rod 43 and the screw nut 44 to drive the door panel assembly 2 to slide, the screw rod 43 itself can provide guidance for the forward and backward movement of the screw nut 44 and can constrain the movement line of the screw nut 44, thereby reducing the risk of the screw nut 44 deviating from the extension direction of the guide rail 11 of the base 1 during movement, thereby reducing the risk of the door panel assembly 2 getting stuck during sliding and improving the operating stability of the hatch assembly.

[0052] Furthermore, when the driving member 42 is specifically configured to drive the screw rod 43 to rotate, the screw rod 43 can be directly driven to rotate by the driving motor 42, for example, a screw rod 43 motor in which the driving motor 42 and the screw rod 43 are integrated can be used. This can simplify the transmission process between the driving motor 42 and the screw rod 43, thereby reducing the cumulative error in the transmission process, thereby reducing the risk of jamming during the sliding process of the door panel assembly 2, and improving the operating stability of the hatch assembly.

[0053] As an optional implementation, continue to refer to Figure 1 When the screw rod 43 is used for driving, the power assembly may further include a screw rod 43 support frame 46. The screw rod 43 support frame 46 is fixedly connected to the support plate 3, specifically fixed to the side of the support plate 3 facing the screw rod 43, and the screw rod 43 support frame 46 is hinged to support the screw rod 43. When the screw rod 43 support frame 46 is specifically set, the screw rod 43 support frame 46 can be rotatably connected to the end of the screw rod 43 away from the driving member 42 and support the screw rod 43 to obtain a better support effect. Since the screw rod 43 itself has a long size, it is easy to cause the screw rod 43 to shake when the screw nut 44 moves on the screw rod 43. By setting up the screw rod 43 support frame 46 to support the screw rod 43, the support effect of the screw rod 43 support frame 46 can be used to reduce the vibration amplitude of the screw rod 43, improve the position accuracy of the screw rod 43, reduce the risk of the door panel assembly 2 sliding and jamming due to the shaking of the screw rod 43, and thus improve the operating stability of the hatch assembly.

[0054] As an optional implementation, continue to refer to Figure 1 The sliding member may further include a slider 45, which is fixedly connected to the door panel assembly 2, and the slider 45 is connected to the screw nut 44 through the flexible transmission member 41, so that. Specifically, Figure 1 As shown, the slider 45 can be set on one of the two door panels. When the screw nut 44 moves back and forth driven by the screw 43, the screw nut 44 can transmit the driving force through the flexible connector 41, driving the slider 45 to move back and forth with the screw nut 44, and then the slider 45 drives the door panel assembly 2 to slide back and forth under the sliding cooperation of the sliding structure.

[0055] The sliding structure further includes a linear slide 12, which is provided on the base 1. The slider 45 is slidably engaged with the linear slide 12, and the slider 45 is also fixedly connected to the door panel assembly 2. The door panel assembly 2 is slidably engaged with the linear slide 12 via the slider 45. When the flexible transmission member 2 is connected to the sliding member, the flexible transmission member 2 is specifically fixedly connected to the slider 45.

[0056] The slider 45 is slidably connected to the linear slide rail 12, and the linear slide rail 12 can be used to further constrain the sliding path of the slider 45, reducing the risk of position error between the power component and the door panel component 2 causing the door panel to slide and get stuck, thereby improving the operating stability of the cabin door assembly.

[0057] As an example, refer to Figure 1 、 Figure 3 as well as Figure 4 , Figure 3 This is a schematic diagram of the arrangement of linear slides and guide rails in an embodiment of the present application. Figure 4 This is an exploded view of some parts of the door assembly in the embodiment of the present application. The linear slide rail 12 and the guide rail 11 can be located on the inner and outer sides of the base 1 respectively. The linear slide rail 12 can be located on the outer side of the base 1, and the guide rail 11 can be located on the inner side of the base 1. It should be understood that the inner and outer sides of the base 1 are relative to the door of the gene sequencer, and the side where the door opening is located is the inner side. The slider 45 may include a linear slide rail connection part 451 and a crossing connection part 452. The linear slide rail connection part 451 is slidably connected to the linear slide rail 12, one end of the crossing connection part 452 is fixedly connected to the linear slide rail connection part 451, and the other opposite end of the crossing connection part 452 spans the base 1 and is connected to the door panel. The flexible connector 41 is slidably connected to the linear slide rail connection part 451, so that the flexible connector 41 can drive the slider 45 and the door panel assembly 2 to slide.

[0058] This arrangement allows the linear slide 12 and the guide rail 11 to be closer without interfering with each other, saving material for the slider 45 and making the overall structure of the door assembly compact. Of course, in other optional embodiments, other arrangements may also be used, which will not be described in detail here.

[0059] Optionally, when specifically configuring the linear guide rail connection portion 451, the linear guide rail connection portion 451 may be composed of two parts, one of which is configured to be slidably connected to the linear guide rail 12, and the other of which is configured to be fixedly connected to the flexible connector 41 and the spanning connection portion 452. Since the portion that is slidably connected to the linear guide rail 12 requires high machining accuracy, the linear guide rail connection portion 451 configured in this manner may be configured to have the two parts machined separately before being fixedly connected together, thereby improving the production efficiency and economical production of the linear guide rail connection portion 451.

[0060] When the support plate 3 and the base 1 are specifically fixedly connected, various methods can be used to achieve the fixed connection between the support plate 3 and the base 1.

[0061] refer to Figure 5 , Figure 5The figure is a schematic diagram of the integrally formed support plate and base in an embodiment of the present application. As an optional embodiment, the support plate 3 can be integrally formed with the base 1. The integrally formed support plate 3 and base 1 can effectively control the positional error of the support plate 3 relative to the base 1 during the production process, thereby reducing the matching error between the power assembly fixed to the support plate 3 and the base 1 or the door panel assembly 2, reducing the risk of the door panel assembly 2 getting stuck during sliding, and improving the stability of the hatch assembly operation.

[0062] refer to Figure 6 , Figure 6 This is a schematic diagram of the separate assembly of the support plate and the base in the embodiment of the present application. As another optional embodiment, the support plate 3 and the base 1 can be fixedly connected by threaded fasteners. Figure 3 As shown, the support plate 3 and base 1 are manufactured separately. During assembly, the support plate 3 overlaps the base 1 and is then fastened together using threaded fasteners. Using a separate production method, the support plate 3 and base 1 can be manufactured separately, saving production costs while ensuring assembly accuracy. Furthermore, the use of threaded fasteners for fastening is convenient and helps improve production efficiency.

[0063] Optional, continue to refer to Figure 3 When the support plate 3 and the base 1 are fixed together using threaded fasteners, some auxiliary positioning structures can be provided between the support plate 3 and the base 1. The provision of the positioning structures can improve the assembly accuracy between the support plate 3 and the base 1, thereby improving the positioning accuracy of the power assembly, reducing the risk of the door panel assembly 2 sliding and jamming due to excessive positional error between the power assembly and the door panel assembly 2, and thus achieving the purpose of improving the operational stability of the hatch assembly.

[0064] In one specific embodiment, a positioning protrusion 31 is provided at one end of the support plate 3 where it overlaps the base 1, and a positioning recess 13 is provided on the base 1 to engage with the positioning protrusion 31. When the support plate 3 is assembled to the support base, the positioning protrusion 31 can be embedded in the positioning recess 13. At this time, the positioning protrusion 31 and the positioning recess 13 are positioned and engaged, thereby effectively positioning and restraining the support plate 3 and the base 1. The use of the positioning protrusion 31 and the positioning recess 13 is easy to implement during the production process and does not require additional positioning devices such as positioning pins. This provides a good positioning effect and can also save production costs.

[0065] It should be understood that, for a support plate 3, one, two or more positioning protrusions 31 may be provided at one end where the support plate 3 overlaps with the base 1, and the number of positioning recesses 13 cooperating therewith may also be one, two or more. The specific number may be determined by the positioning effect during the specific implementation process, and will not be elaborated here.

[0066] Of course, the method of fixing the support plate 3 and the base 1 is not limited to one-piece molding or threaded connection. In other possible implementations, the support plate 3 and the base 1 can also be fixedly connected by welding, riveting, etc., which will not be elaborated here.

[0067] An embodiment of the present application also provides a gene sequencer, which includes a gene sequencer body and a hatch assembly such as any one of the above-mentioned ones arranged on the gene sequencer body.

[0068] The hatch assembly provided on the gene sequencer body is fixedly connected to the base by providing a support plate, and the power assembly is fixed to the support plate. The support plate can be used to more accurately fix the power assembly to the correct position, and it is easy to control the relative position deviation between the power assembly and the base and the door panel assembly, thereby improving the assembly accuracy of the power assembly and the hatch assembly, and thereby improving the stability of the automatic hatch operation.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification shall be included within the scope of protection of this disclosure.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application.
