Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a housing assembly and a gene sequencer. Background Technology

[0002] Gene sequencers and other instruments and equipment (including but not limited to testing instruments, industrial equipment, medical equipment, etc.) usually have some external interfaces reserved for connecting external devices or functional components to achieve the versatility of instrument and equipment functions.

[0003] For some instruments and equipment, the external interface is located on a housing panel that needs to be assembled with other parts of the housing in a push-in manner in one direction, and the push-in direction of the housing panel is perpendicular to the axial direction of the external interface.

[0004] For the aforementioned instruments and equipment, some related technologies directly fix the external interface to the equipment shell. This setup requires an additional extension cable between the original interface inside the equipment and the interface on the outer shell panel to ensure that the outer shell panel can be properly assembled, disassembled, and maintained.

[0005] In other related technologies, the external interface is directly fixed to the internal frame of the equipment, and holes corresponding to the external interface are reserved on the outer panel. This setting makes it difficult to ensure that the external interface and the outer panel can fit together precisely, and it is easy to leave a large assembly gap between the outer panel and the external interface. Summary of the Invention

[0006] This application provides a shell assembly and a gene sequencer.

[0007] Firstly, the housing assembly provided in this application can be applied to external interface devices, and the housing assembly includes:

[0008] The housing has interface holes; The base is fixed inside the external interface device; A cover plate is located between the base and the interface hole and is disposed opposite to the interface hole; the cover plate is used to fix the wiring terminal. A sliding assembly is used to slidably connect the cover plate to the base and to drive the cover plate to slide along the depth direction of the interface hole; The sliding assembly can be in a locked state and an unlocked state; when the sliding assembly is in the locked state, the sliding assembly locks the cover plate in a first position away from the housing; when the sliding assembly is in the unlocked state, the sliding assembly drives the cover plate to abut against the housing and block the interface hole.

[0009] In one possible implementation, the sliding assembly includes a slide bar, a track, a first elastic element, and a second elastic element; The first elastic element is used to apply an elastic force to the cover plate away from the base; the first end of the slide rod is hinged to the cover plate, and the second end of the slide rod is slidably connected to the track; the second elastic element is disposed between the cover plate and the first end of the slide rod, and drives the slide rod to abut against the side wall of the track; The track is set on the base; the second end slides within the track to switch between the locked state and the unlocked state.

[0010] In one possible implementation, the track includes a starting segment and a first locking segment, the starting segment and the first locking segment being spaced apart along the depth direction of the interface hole, and the starting segment being located on the side of the first locking segment closer to the interface hole; the track also includes a first branch segment and a second branch segment, the first branch segment and the second branch segment respectively connecting the starting segment and the first locking segment; the first branch segment and the second branch segment are spaced apart; When the second end is located in the starting section, under the pushing action of the external force applied to the cover plate, the second end can enter the first locking section along the first branch section, and when the external force is released, the second end is locked in the first locking section; When the second end is locked within the first locking section, under the pushing action of the external force applied to the cover plate, the second end can enter the second branch section from the first locking section under the action of the second elastic member, and after the external force is released, enter the starting section along the second branch section under the action of the first elastic member until the cover plate abuts against the housing.

[0011] In one possible implementation, the track further includes a second locking segment located on the side of the starting segment pointing from the first branch segment to the second branch segment, and the second locking segment is in communication with the starting segment; When the cover plate abuts against the housing, the second end enters the second locking section from the starting section under the action of the second elastic member; The second locking section is used to limit the sliding stroke of the second end in the depth direction of the interface hole; The cover plate is provided with an unlocking hole, so that the second end can be driven to disengage from the second locking section and enter the starting section by an unlocking member that passes through the unlocking hole.

[0012] In one possible implementation, along the depth direction of the interface hole, the farthest distance between the position of the second end when it is in the second locking section and the position of the second end when it is locked in the first locking section is S1, and the closest distance is S2; the position of the cover plate when it abuts against the housing is the second position, and the distance between the first position and the second position of the cover plate is L; the comprehensive deviation of the cover plate in the depth direction of the interface hole is Δt. S1, S2, L, and Δt satisfy: S1≥L+Δt, S2≤L-Δt.

[0013] In one possible implementation, the first locking segment includes a guide protrusion, a locking region opposite to the guide protrusion, a first guide segment located on the side of the guide protrusion facing the first branch segment, and a second guide segment located on the side of the guide protrusion facing the second branch segment; the locking region has a first locking wall opposite to the guide protrusion, and a second locking wall located at the end of the locking region near the second branch segment; the second locking wall is located on the side of the guide protrusion facing the second branch segment; After the second end slides to the end of the first branch segment that is away from the interface hole, it can enter the first guide segment under the action of the second elastic member, and enter the locking area under the guidance of the guide protrusion. Finally, the slide rod abuts against the first locking wall under the action of the first elastic member, and the slide rod abuts against the second locking wall under the action of the second elastic member. When the slide bar abuts against the first locking wall and the second locking wall, an external force is applied to push the slide bar. The slide bar enters the second guide section under the guidance of the guide protrusion, and slides to the end of the second branch section opposite to the interface hole under the action of the second elastic member.

[0014] In one possible implementation, at the intersection of the second branch segment, the first branch segment, and the starting segment, the second branch segment is higher than the starting segment along the depth direction of the track. The sliding assembly further includes a third elastic element for applying force to the slide bar, such that the second end is always in contact with the bottom surface of the track.

[0015] In one possible implementation, the sliding assembly further includes a guide post, which is fixedly connected to the cover plate and slidably connected to the base; The first elastic element is a first compression spring, which is sleeved on the guide post and pressed against the cover plate and the base.

[0016] In one possible implementation, the housing is turned inward along the edge of the interface hole toward the direction of the cover plate to form a flange; The flange is used to abut against the cover plate.

[0017] In one possible implementation, along the depth direction of the interface hole, the height of the flange is greater than or equal to the height of the terminal protruding from the cover plate.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0023] To facilitate understanding of the housing assembly provided in the embodiments of this application, its application scenario is first described. The housing assembly provided in the embodiments of this application can be applied to external interface devices. Here, an external interface device refers to a device with an external interface, specifically, it can be various devices such as testing instruments, industrial equipment, and medical devices. This device can perform functions including but not limited to power transmission and signal transmission through the external interface.

[0024] refer to Figure 1 , Figure 1 This is a schematic diagram of the assembly of a housing panel for a device with an external interface. The device can be various types of equipment, such as testing instruments, industrial equipment, and medical devices. In this embodiment, a gene sequencer is used as an example of a medical device. The external interface 01 is mounted on a housing panel 02, which needs to be able to connect in one direction (e.g., along a direction such as...). Figure 1 The housing panel 02 is pushed in in the direction indicated by the middle arrow and assembled with other parts of the housing, and the pushing direction of the housing panel 02 is perpendicular to the axial direction of the external interface 01.

[0025] For such instruments and equipment, some related technologies directly fix the external interface 01 to the instrument housing. This setup requires an additional extension cable between the original interface inside the equipment and the interface on the housing panel 02 to ensure that the housing panel 02 can be properly assembled, disassembled, and maintained. Specifically, the length of this extension cable must be at least longer than the distance between the interface on the housing panel 02 and the original interface to ensure that the housing panel 02 can be assembled with other parts of the housing by pushing it in.

[0026] In other related technologies, the external interface 01 is directly fixed to the internal frame of the equipment, and a hole corresponding to the external interface 01 is reserved on the outer panel 02. This arrangement makes it difficult to ensure a precise fit between the external interface 01 and the outer panel 02, easily leaving a large assembly gap between them. These gaps arise from manufacturing errors in the outer panel 02 itself and assembly errors between the outer panel 02 and internal components of the instrument. Furthermore, for cases where the terminals of the external interface 01 protrude, a hole is needed between the outer panel 02 and the external interface 01 to accommodate the protruding portion of the terminals, thus preventing interference between the outer panel 02 and the terminals during assembly.

[0027] In the above-mentioned solution using an extension cable, the extension cable is randomly suspended inside the instrument, which is easily damaged due to friction, resulting in poor line stability of the external interface 01. In the above-mentioned solution of directly fixing the external interface 01 to the internal frame of the instrument, it is difficult to avoid leaving gaps at the external interface 01, which leads to a decrease in the sealing of the equipment shell.

[0028] Based on this, this application provides a housing assembly and a gene sequencer, aiming to provide an external interface solution for the gene sequencer with high circuit stability and good housing sealing. The housing assembly provided in this application is described in detail below with reference to the accompanying drawings.

[0029] Please refer to the above. Figure 2 and Figure 3 , Figure 2 This is a schematic diagram showing the cover plate in the first position in an embodiment of this application. Figure 3 This is one of the schematic diagrams showing the cover plate in the second position in an embodiment of this application.

[0030] The housing assembly provided in this application can be applied to an external interface device. The housing assembly includes a housing 1 with an interface hole. Specifically, the housing 1 is part of the overall housing of the external interface device. The housing 1 can be assembled with other parts of the overall housing of the external interface device by pushing it in a set direction, and the set direction of pushing the housing 1 can be perpendicular to the depth direction of the interface hole.

[0031] The housing assembly also includes a base 2, a cover plate 3, and a sliding assembly 5. The base 2, cover plate 3, and sliding assembly 5 together form a functional component for carrying the terminal block 4.

[0032] Specifically, the base 2 is fixed inside the device with the external interface, and the base 2 is positioned opposite to the interface hole. The base 2 can be fixed to a sheet metal part or frame inside the external interface device, and the base 2 can be fixed inside the external interface device before the housing 1 is assembled to the external interface device.

[0033] The cover plate 3 is located between the base 2 and the interface hole and is positioned opposite to the interface hole. The cover plate 3 is slidably connected to the base 2 via the sliding assembly 5. This cover plate 3 is used to fix the wiring terminal 4. Specifically, the wiring terminal 4 on the cover plate 3 can be connected to the circuit board inside the external interface device via wires. In this way, power transmission or signal transmission between the external interface device and other devices can be achieved through the connection between the external power cord, signal line, and other wires and the wiring terminal 4.

[0034] The sliding component 5 is used to drive the cover plate 3 to slide along the depth direction of the interface hole. The cover plate 3 can be in a first position and a second position on the sliding path, and the first position and the second position are a certain distance apart along the depth direction of the interface hole. When the cover plate 3 is in the first position, there is a certain distance between the cover plate 3 and the interface hole of the housing 1 in the depth direction of the interface hole. When the cover plate 3 is in the second position, the cover plate 3 abuts against the housing 1 and the cover plate 3 blocks the interface hole.

[0035] The sliding component 5 can be in two states: locked and unlocked. When the sliding component 5 is in the locked state, it locks the cover plate 3 in a first position away from the housing 1. When the sliding component 5 is in the unlocked state, it drives the cover plate 3 to slide along the depth direction of the interface hole toward the side where the housing 1 is located. That is, the sliding component 5 drives the cover plate 3 to slide from the first position to the second position until the cover plate 3 reaches the second position, where it abuts against the housing 1 and seals the interface hole.

[0036] It is worth noting that the terminal 4 can be set on the side of the cover plate 3 facing the interface hole, or it can be inserted into the hole on the cover plate 3. Regardless of how the terminal 4 is set, when the cover plate 3 is in the second position, the terminal 4 is exposed to the outer casing of the external interface device through the interface hole.

[0037] The sliding component 5 can be fixed in the first position by means of hooks, track 52 design, magnetic adsorption, etc., and the sliding component 5 can drive the cover plate 3 to slide from the first position to the second position by means of springs, hydraulic push rods, pneumatic push rods, etc.

[0038] It is also worth emphasizing that, with user intervention, the sliding component 5 can switch between a locked state and an unlocked state. That is, when the sliding component 5 is in the locked state, the user can trigger a mechanism or perform other operations to switch the sliding component 5 to the unlocked state; similarly, when the sliding component 5 is in the unlocked state, the user can push the cover 3 back or perform other operations to return the cover 3 from the second position to the first position and lock the sliding component 5.

[0039] During assembly, the sliding component 5, cover plate 3, and base 2 are first fixed to the sheet metal parts or frame inside the external interface device, and the sliding component 5 is kept locked. At this time, the terminal 4 can be connected to the set position inside the external interface device through a wire. Then, the housing 1 is pushed along the direction perpendicular to the depth of the interface hole to assemble with other parts of the housing of the external interface device. This continues until the housing 1 is fully assembled with the other parts of the housing of the external interface device, at which point the interface hole and cover plate 3 are aligned along the depth of the interface hole. Then, the user can operate the sliding component 5 to change it from the locked state to the unlocked state. The sliding component 5 then drives the cover plate 3 to slide toward the interface hole until the cover plate 3 abuts against the housing 1 and seals the interface hole. This completes the assembly of the housing component.

[0040] When it is necessary to remove the housing 1 for internal maintenance of external interface instruments, the user can first push the cover plate 3 back and operate the sliding component 5 to lock the cover plate 3 in the first position, so that the wiring terminal 4 is spaced a certain distance from the housing 1. Then, push the housing 1 out in the opposite direction of the pushing direction during installation to complete the disassembly of the housing 1.

[0041] The housing assembly provided in this application has its external interface fixed inside the device, eliminating the need for additional extension cables and enabling the external interface device to have better line stability. Furthermore, the cover plate 3 can be locked in the first position to meet the installation requirements of the housing 1, and can also be unlocked to abut against the housing 1 to reduce the gap between the external interface and the housing 1, thereby providing better sealing for the external interface device's housing. In summary, the housing assembly provided in this application achieves the goal of providing an external interface solution with high line stability and good housing sealing for external interface devices.

[0042] Please refer to the above. Figure 4 , Figure 5 and Figure 6 , Figure 4 This is the second schematic diagram showing the cover plate in the second position in this embodiment of the application. Figure 5 This is an exploded view of some parts of the outer casing assembly in an embodiment of this application. Figure 6 This is a schematic diagram of the base and track in an embodiment of this application.

[0043] As an optional implementation, when specifically setting the sliding component 5, the sliding component 5 includes a slide rod 51, a track 52, a first elastic element 53, and a second elastic element 54. To facilitate the description of the sliding component 5 provided in this application, some reference directions are selected in space. For example, the X-axis direction shown in the attached figure is the depth direction of the interface hole, and the direction from the cover plate 3 to the base 2 is defined as the positive direction of the X-axis; furthermore, the Y-axis and Z-axis directions shown in the figure are both perpendicular to the X-axis direction, and the Y-axis direction is also perpendicular to the Z-axis direction.

[0044] The track 52 is mounted on the base 2. Specifically, the base 2 may have a bearing surface 21 parallel to the X-axis. For ease of description, the Y-axis is also defined to be parallel to this bearing surface 21. The track 52 is formed on this bearing surface 21, and from an overall perspective, the track 52 has an extension in the direction parallel to the X-axis.

[0045] The slide rod 51 extends approximately along the X-axis. Along the X-axis, the slide rod 51 has two opposing ends, which are named the first end 511 and the second end 512, respectively. The first end 511 of the slide rod 51 is hinged to the cover plate 3. Specifically, the first end 511 is hinged to the side of the cover plate 3 facing the base 2. The axis of hinge between the first end 511 and the cover plate 3 is parallel to the Z-axis, meaning the slide rod 51 can rotate about the hinge center in a plane parallel to the bearing surface 21 (i.e., the XY plane). The second end 512 of the slide rod 51 is slidably connected to the track 52. Specifically, the slide rod 51 can move at least within the track 52 along both the positive and negative X-axis directions, thereby satisfying the adjustment requirements of the cover plate 3's position.

[0046] In the specific configuration of the first elastic element 53, the first elastic element 53 is used to apply a spring force to the cover plate 3 away from the base 2. Specifically, the first elastic element 53 acts between the cover plate 3 and the base 2 and is used to drive the cover plate 3 to move in the negative X direction. The specific form of the first elastic element 53 can be a spring, a spring-loaded pin, etc. It is easy to see that when the sliding assembly 5 is in the unlocked state, the first elastic element 53 can drive the cover plate 3 to abut against the interface hole, and at the same time, the user can also push the cover plate 3 to move it to the first position in the positive X direction and lock it.

[0047] The sliding assembly 5 also includes a second elastic element 54, which is disposed between the first end 511 of the slide rod 51 and the cover plate 3, and drives the slide rod 51 to abut against the side wall of the track 52. Specifically, since the first end 511 of the slide rod 51 is also hinged to the cover plate 3, the second elastic element 54 causes the slide rod 51 to rotate about the hinge center, i.e. Figure 4 The second elastic element 54 is used to apply a spring force to the second end 512 of the slide rod 51 in the direction from the first branch segment 523 to the second branch segment 524, in order to rotate clockwise. That is, the second elastic element 54 is used to apply a force that causes the second end 512 to move in the negative Y-axis direction within the track 52, thereby causing the slide rod 54 to abut against the side wall of the track 52 located on the negative Y-axis side.

[0048] The second end 512 slides within the track 52 to switch between locked and unlocked states. Specifically, the track 52 and the second end 512 of the slide rod 51 cooperate to form a "PUSH-PUSH" structure. When the cover plate 3 is in the first position and the sliding assembly 5 is in the locked state, pushing the cover plate 3 causes the slide rod 51 to slide within the track 52, which in turn switches the sliding assembly 5 to the unlocked state. The sliding assembly 5 then drives the cover plate 3 to slide towards the interface hole until it abuts against the housing 1 and seals the interface hole. When the cover plate 3 is in the second position and the sliding assembly 5 is in the unlocked state, pushing the cover plate 3 causes the slide rod 51 to slide within the track 52, which pushes the cover plate 3 to the first position and switches the sliding assembly 5 to the locked state, thereby locking the cover plate 3 in the first position.

[0049] Please refer to the above. Figure 7 , Figure 7 This is one of the track diagrams in the embodiments of this application.

[0050] As an optional implementation, when specifically setting the track 52, the track 52 includes a starting segment 521, a first branch segment 523, a second branch segment 524, and a first locking segment 522. The starting segment 521 is located at the end of the track 52 near the interface hole, and the first locking segment 522 is located at the end of the track 52 near the base 2. The first branch segment 523 and the second branch segment 524 are respectively connected to the starting segment 521 and the first locking segment 522, and the first branch segment 523 and the second branch segment 524 are spaced apart. Specifically, the first branch segment 523 and the second branch segment 524 are spaced apart approximately along the Y-axis direction, and the first branch segment 523 and the second branch segment 524 extend approximately along the X-axis direction. The direction from the second branch segment 524 to the first branch segment 523 is now considered as the positive Y-axis direction. The starting segment 521 is a section of track 52 extending approximately along the X-axis direction. The starting segment 521 is connected to the first branch segment 523 and the second branch segment 524 to form a "Y"-shaped fork. The first locking segment 522 is a section of track 52 extending approximately along the Y-axis direction. The first branch segment 523 and the second branch segment 524 are respectively connected to the two ends of the first locking segment 522.

[0051] When the second end 512 is located in the starting section 521, an external force is applied to push the slide bar 51. The second end 512 can enter the first locking section 522 along the first branch section 523, and when the external force is released, the second end 512 is locked in the first locking section 522. In a specific example, for the cover plate 3 located in the second position, when the cover plate 3 is pushed in the positive X-axis direction to a set position on the side opposite to the second position of the first position, the additional force applied to the cover plate 3 is released. The cover plate 3 will slide to the second position under the drive of the first elastic member 53. During this sliding process, the second end 512 is acted upon by the second elastic member 54 to enter the first locking section 522, and finally locks the cover plate 3 in the first position.

[0052] When the second end 512 is locked within the first locking section 522, an external force is applied to push the cover plate 3 along the positive X-axis. The cover plate 3 pushes the slide rod 51 to slide along the positive X-axis within the track. During the sliding process, the second end 512 of the slide rod 51 is acted upon by the second elastic element 54, moving from the first locking section 522 into the second branch section 524. After the external force is released, under the action of the first elastic element 53, it moves along the second branch section 524 into the starting section 521 until the cover plate 3 abuts against the housing 1. In a specific example, when the cover plate 3 is in the first position, it is pushed to the side away from the second position. The second end 512 moves from the first locking section 522 into the second branch section 524 and finally returns to the starting section 521, where the cover plate 3 abuts against the housing 1.

[0053] The sliding component 5, as described above, features a simple structure and convenient operation.

[0054] As an optional implementation, when specifically configuring the first locking segment 522, the first locking segment 522 includes a first guide segment 5223, a guide protrusion 5221, a locking area 5222, and a second guide segment 5224. The first guide segment 5223, the locking area 5222, and the second guide segment 5224 are sequentially connected along the negative Y-axis. The end of the first guide segment 5223 facing away from the locking area 5222 is connected to the first branch segment 523, and the end of the second guide segment 5224 facing away from the locking area 5222 is connected to the second branch segment 524.

[0055] The guide protrusion 5221 is disposed opposite to the locking area 5222. Specifically, the guide protrusion 5221 is located on the positive X-axis side of the locking area 5222, and can be formed by the sidewall of the locking area 5222 protruding outwards towards the negative X-axis from the positive X-axis side. In the Y-axis direction, the guide protrusion 5221 is located in the middle section of the locking area 5222. The first guide segment 5223 is located on the side of the locking area 5222 facing the first branch segment 523, and the second guide segment 5224 is located on the side of the locking area 5222 facing the second branch segment 524. When the locking area 5222 and the first guide segment 5223 and the second guide segment 5224 are specifically arranged, the locking area 5222 is located on the negative X-axis side of the first guide segment 5223 and the second guide segment 5224.

[0056] The locking region 5222 has a first locking wall 5225 opposite to the guide protrusion 5221. The first locking wall 5225 is opposite to the guide protrusion 5221 in the X direction and is used to abut against the second end 512 of the slide bar 51 in the X-axis direction to lock the slide bar 51 against the elastic force of the first elastic member 53 in the X-axis direction.

[0057] The locking region 5222 also has a second locking wall 5226, which is located at the end of the locking region 5222 near the second branch segment 524, and is located on the side of the guide protrusion 5221 facing the second branch segment 524. The second locking wall 5226 is used to abut against the second end 512 of the slide bar 51 in the Y-axis direction to restrict the second end 512 within the locking region 5222 in the Y-axis direction against the elastic force of the second elastic member 54.

[0058] The second elastic element 54 continuously applies a torsional force to the slide rod 51, causing the second end 512 to tend to move in the negative Y-axis direction. After sliding from the first branch section 523 along the positive X-axis to the end of the first branch section 523 away from the interface hole, the second end 512 can enter the first guide section 5223 under the action of the second elastic element 54. The second end 512 continues to move in the negative Y-axis direction within the first guide section 5223 under the action of the second elastic element 54 until it abuts against the guide protrusion 5221. Then, under the action of the first elastic element 53, the second end 512 turns and slides in the negative X-axis direction and enters the locking area 5222. Within the locking area 5222, the first locking wall 5225 abuts against the second end 512 to resist the elastic force of the first elastic element 53, and the second locking wall 5226 abuts against the second end 512 to resist the elastic force of the second elastic element 54. The sliding assembly 5 is in a locked state at this time, and the cover plate 3 is in the first position.

[0059] When the second end 512 is locked in the locking area 5222, pushing the cover plate 3 along the positive X-axis will cause the second end 512 to slide along the positive X-axis. The second locking wall 5226 is located on the side of the guide protrusion 5221 near the second guide section 5224. Therefore, when the second end 512 slides along the positive X-axis against the second locking wall 5226, it will be guided by the guide protrusion 5221. The second end 512 enters the second guide section 5224 from the side of the guide protrusion 5221 near the second guide section 5224, and then slides along the negative Y-axis to the end of the second branch section 524 away from the interface hole under the action of the second elastic member 54. Finally, under the action of the first elastic member 53, it returns to the starting section 521 from the second branch section 524 along the negative X-axis.

[0060] In a specific example, the first locking segment 522 can be presented as follows: Figure 7 In some other embodiments, the first locking segment 522 may also be in the form of a "V", "U" or similar shape.

[0061] The first locking section 522, configured in this way, utilizes the guiding effect of the guide protrusion 5221 in conjunction with the first elastic element 53 and the second elastic element 54 to achieve unidirectional conduction of the second end 512 from the first branch section 523 through the first locking section 522 to the second branch section 524, so that the second end 512 can slide within the track to achieve the switching of the sliding component 5 between the locked and unlocked states.

[0062] Please refer to the above. Figure 8 , Figure 8 This is the second schematic diagram of the track in the embodiments of this application.

[0063] As an optional implementation, at the intersection of the second branch segment 524, the first branch segment 523, and the starting segment 521, along the depth direction of the track 52, the second branch segment 524 is higher than the starting segment 521. Furthermore, the second branch segment 524 is also higher than the first branch segment 523, and the first branch segment 523 and the starting segment 521 are smoothly connected. This creates a stepped structure at the "Y"-shaped fork. The sliding assembly 5 also includes a third elastic element 55, which applies force to the slide rod 21 and ensures that the second end 512 is always in contact with the bottom surface of the track. Specifically, the third elastic element 55 applies a spring force along the positive Z-axis to the slide rod 51, thereby causing the second end 512 to abut against the bottom wall of the track 52 along the positive Z-axis. In a specific example, the third elastic element 55 is a third compression spring, the slide rod 51 is hinged to the cover plate by bolts, and the third compression spring is sleeved on the bolts and presses against the nut and the slide rod 51, thereby applying a spring force to the slide rod 51 so that the second end 512 can abut against the bottom wall of the track 52.

[0064] Thus, when the second end 512 slides from the starting segment 521 along the positive X-axis and passes through the intersection of the second branch segment 524, the first branch segment 523 and the starting segment 521, the second end 512 will be restricted by the height difference between the second branch segment 524 and the starting segment 521, so that the second end 512 can only enter the first branch segment 523.

[0065] The track 51 configured in this way can prevent the second end 512 from mistakenly entering the second branch section 523 from the starting section 521 along the positive X-axis through physical structural constraints, and can reduce the risk of the second end 512 derailing when sliding within the track 52.

[0066] As an optional implementation, when specifically setting the track 52, the track 52 further includes a second locking section 525. The second locking section 525 is located on the side of the starting section 521 in the direction from the first branch section 523 to the second branch section 524 (that is, the negative direction of the Y axis), and the second locking section 525 is connected to the starting section 521. When the cover plate 3 abuts against the housing 1, the second elastic member 54 can drive the second end 512 from the starting section 521 into the second locking section 525. The second locking section 525 is used to limit the travel of the second end 512 in the depth direction (that is, the X-axis direction) of the interface hole.

[0067] Specifically, both ends of the second locking section 525 along the X-axis and the end in the negative Y-axis direction have abutment walls. When the second end 512 is located within the second locking section 525, under the action of the second elastic member 54, the second end 512 always abuts against the abutment wall in the negative Y-axis direction. Therefore, the second locking section 525 can limit the stroke of the second end 512 between the abutment walls at both ends of the second locking section 525 along the X-axis direction.

[0068] During the movement of cover plate 3 from the first position to the second position, after the second end 512 moves to the first starting section 521, it automatically enters the second locking section 525 under the action of the second elastic element 54. When it is necessary to disassemble housing 1, the user needs to use a tool or directly push the second end 512 in the positive Y-axis direction so that the second end 512 enters the starting section 521, and then push the cover plate 3 in the positive X-axis direction to the end of the first branch section 523 to lock the cover plate 3 in the first position so that housing 1 can be removed.

[0069] In the specific configuration of the cover plate 3, the cover plate 3 also has an unlocking hole 32, through which the second end 512 is driven to disengage from the second locking section 525 and enter the starting section. Specifically, the unlocking hole 32 is used for the rod to pass through and abut against the slide bar 51, so as to drive the second end 512 to slide from the second locking section 525 to the starting section 521 against the elastic force of the second elastic member 54. Specifically, the housing assembly may be equipped with a special tool, which can pass through the unlocking hole 32 and abut against the slide bar 51, and can drive the slide bar 51 to rotate, thereby allowing the second end 512 to enter the starting section 521.

[0070] By providing the second locking section 525, the risk of poor contact between the cable and the external interface caused by pushing the cover plate 3 along the positive X-axis when plugging in the cable can be reduced. By providing the unlocking hole 32, the housing 1 can be easily disassembled, and by increasing the difficulty of unlocking, the risk of accelerated wear caused by frequent disassembly of the sliding component 5 can be reduced.

[0071] As an optional implementation, along the depth direction (X-axis direction) of the interface hole, the farthest distance between the position of the second end 512 when it is in the second locking section 525 and the position when the second end 512 is locked in the first locking section 522 is S1, and the closest distance is S2; when the second end 512 is locked in the position of the first locking section 522, the distance between the cover plate 3 and the housing 1 is L; the comprehensive deviation of the cover plate 3 in the depth direction of the interface hole is Δt; S1, S2, L and Δt satisfy: S1≥L+Δt, S2≤L-Δt.

[0072] When the overall deviation of cover plate 3 is zero, cover plate 3 can move a distance L relative to the first position towards housing 1 to abut against housing 1. However, when the overall deviation of cover plate 3 is +Δt, it means that cover plate 3 has shifted Δt relative to the theoretical position in the positive X-axis direction. Therefore, for cover plate 3 to abut against housing 1, it needs to move a distance L + Δt towards housing 1. Thus, by setting S1≥L + Δt, it can be ensured that under the limit deviation, there will be no gap between cover plate 3 and housing 1 due to the travel limitation of the second locking section 525.

[0073] When the overall deviation of cover plate 3 is -Δt, it means that cover plate 3 has shifted Δt in the negative X-axis direction relative to its theoretical position. Therefore, for cover plate 3 to abut against housing 1, it only needs to move L - Δt towards housing 1. Thus, by setting S2≤L - Δt, it can be ensured that under the limit deviation, the second end 512 will not be unable to enter the second locking section 525 due to the stroke limitation of the second locking section 525.

[0074] In summary, by setting S1, S2, L, and Δt to meet the above conditions, the tolerance of the sliding assembly 5 to deviations in the dimensions of the components themselves and to assembly deviations between components can be improved, thereby reducing production difficulty and cost.

[0075] As an optional implementation, the sliding assembly 5 further includes a guide post 31, the length direction of which is parallel to the depth direction of the interface hole; the guide post 31 is fixedly connected to the cover plate 3 and slidably connected to the base 2. The first elastic element 53 is a first compression spring, which is sleeved on the guide post 31 and pressed between the cover plate 3 and the base 2.

[0076] In this optional embodiment, the cooperation between the guide post 31 and the guide hole ensures that the cover plate 3 can only move in a straight line along the depth direction of the interface hole, effectively reducing the risk of the cover plate 3 tilting due to uneven force, thereby improving the stability of the slide rod 51 within the track 52. In addition, by sleeved the first compression spring on the guide post 31, the guide post 31 can be used as a mounting seat and guide rod for the spring, reducing the risk of the first compression spring twisting or bending laterally during compression and release.

[0077] Optionally, to further improve the stability of the sliding connection between the cover plate 3 and the base 2, four guide posts 31 are provided, with each guide post positioned at one of the four corners of the cover plate 3. Optionally, four first compression springs are also provided, each corresponding to one of the four guide posts 31.

[0078] As an optional implementation, the second elastic element 54 is a second compression spring, with one end pressing against the cover plate 3 and the other end pressing against the second end 512 of the slide rod 51. The second compression spring is pre-compressed, consistently applying a lateral force pointing towards the second branch segment 524 to the second end 512 of the slide rod 51, thereby giving the slide rod 51 a rotational tendency, and consequently, giving the second end 512 a tendency to move in the negative Y-axis direction. This configuration of the second elastic element 54 offers advantages such as simple structure and ease of maintenance.

[0079] Of course, in other possible implementations, the second elastic element 54 can also be a torsion spring, which can act at the hinge between the slide rod 51 and the cover plate 3, and make the second end 512 tend to move in the negative direction of the Y axis by applying torque to the slide rod 51.

[0080] As an optional implementation, the housing 1 is turned inward along the edge of the interface hole toward the direction of the cover plate 3 to form a flange 11; the flange 11 is used to abut against the cover plate 3; that is, when the cover plate 3 is in the second position, the cover plate 3 does not abut against the entire inner wall of the housing 1, but abuts against the flange 11.

[0081] By setting the flange 11, when the flange 11 abuts against the cover plate 3, a line contact is actually formed between the housing 1 and the cover plate 3, which helps to reduce the gap between the flange 11 and the cover plate 3, thereby improving the sealing performance of the housing assembly. On the other hand, the area enclosed by the flange 11 can be regarded as a countersunk hole opened by the housing 1 towards the inside of the device. When the wiring terminal 4 protrudes outward on the side of the cover plate 3 away from the base 2, the area enclosed by the flange 11 can accommodate at least part of the protruding wiring terminal 4, which can improve the safety and aesthetics of the external interface device.

[0082] As an optional implementation, along the depth direction of the interface hole, the height of the flange 11 is greater than or equal to the height of the terminal 4 protruding from the cover plate 3. With this configuration, the area enclosed by the flange 11 can completely accommodate the portion of the terminal 4 protruding from the cover plate 3 on the side opposite to the base 2, thereby further improving the safety and aesthetics of the external interface device.

[0083] This application embodiment also provides a gene sequencer, which includes a device body and a housing component as described above for covering the device body; wherein, the device body is used to sequence the sequencing object, the base is fixed to the device body, and the housing is slidable relative to the device body; a connecting wire is led out from the device body, and the terminal of the connecting wire is fixed to the cover plate.

[0084] The external interface device's housing assembly, with its external interface fixed inside the device, eliminates the need for additional extension cables, thus providing better line stability. Furthermore, the cover can be locked in the first position to meet the housing's installation requirements, and can also be unlocked to abut against the housing, reducing the gap between the external interface and the housing, thereby ensuring better sealing of the gene sequencer's housing. In summary, the gene sequencer provided in this application achieves the goal of providing an external interface solution with high line stability and good housing sealing.
