Description

Technical Field

[0001] This invention provides a housing structure, an electronic endoscope image processor, and an assembly method, belonging to the field of electronic endoscope technology. Background Technology

[0002] An electronic endoscope image processor, also known as an electronic endoscope host, receives images from the electronic endoscope, processes them, and then transmits the processed images to a monitor for display. An electronic endoscope image processor typically consists of a housing and a circuit board housed within the housing.

[0003] Currently, the housing structure of electronic endoscope image processors is complex, making manufacturing and installation inconvenient. For example, the patent with announcement number CN221264278U provides an endoscope main unit chassis, which includes a U-shaped bottom shell, a front box plate, a rear box plate, and an envelope cover plate. In this patent solution, the connection structure between the front box plate, the rear box plate, and the U-shaped bottom shell is complex, resulting in difficulty in alignment during assembly. Furthermore, the chassis adopts a hybrid fixing method of multiple screw connections and multiple snap-fit ​​and slot connections, which further prolongs the overall assembly cycle and affects assembly efficiency.

[0004] For example, patent CN213525037U discloses an endoscope video processing host, which includes components such as a panel, partition, base, shell, and rear cover. The base of this host has outwardly extending folded plates on both the front and rear ends, and sliding grooves on both internal sides. The rear cover is inserted into and fixedly connected to the folded plates on both rear ends of the base via slots. This solution effectively reduces the difficulty of assembly alignment through the sliding groove structure design; however, the integration of numerous sliding grooves, folded plates, and tongue-and-groove auxiliary connection structures on the shell results in a complex overall structure of the host, increasing the complexity of the host's manufacturing and assembly processes.

[0005] In summary, the problem we need to solve is how to provide a shell structure that is simple in structure and can be quickly assembled. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention provides a housing structure, an electronic endoscope image processor, and an assembly method. The housing structure is simple in structure and the assembly of the housing components is easy to align, enabling rapid assembly of the housing.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a housing structure for an electronic device. The housing structure includes a lower housing, an upper housing, and a panel. The lower housing includes a base plate and a first side plate connected to both sides of the base plate in the width direction and perpendicular to the base plate. A bent plate is connected to the top of the inner side of the first side plate. The panel is connected to both ends of the lower housing in the length direction, and the end face of the panel mounting part contacts the end face of the first side plate and the bent plate. The upper housing includes a top plate and a second side plate connected to both sides of the top plate in the width direction and perpendicular to the top plate. The mounting parts of the second side plate of the upper housing and the panel slide in a sliding fit along the height direction. When the upper housing slides into place, the bottom surface of the second side plate contacts the top surface of the first side plate, and the inner side of the second side plate contacts the outer side of the bent plate.

[0008] Preferably, the housing structure of the present invention is used in an electronic endoscope graphics processor device.

[0009] Preferably, the bending plate and the first side plate are parallel, that is, both the bending plate and the first side plate are perpendicular to the bottom plate, and the overall upper and lower shells have a U-shaped structure.

[0010] Preferably, there are two panels, which are respectively connected to the two ends of the lower shell along its length, that is, the two open ends of the U-shaped lower shell along its length.

[0011] In one specific embodiment, the panel is a box structure with one end open to form a cavity inside the panel. The assembly part includes a first assembly part and a second assembly part, with the second assembly part located on the side close to the cavity. The end face of the first side plate is in contact with the end face of the first assembly part, and the end face of the bent plate is in contact with the end face of the second assembly part.

[0012] Preferably, the end faces of the first assembly part and the second assembly part are both frame-shaped, that is, the first assembly part and the second assembly part are arranged in a circle around the cavity.

[0013] In one specific embodiment, the first assembly part and the second assembly part are arranged in a stepped manner, with the second assembly part protruding from the first assembly part; the panel and the lower housing slide together along the length direction, and during the sliding engagement, the outer side of the second assembly part contacts the inner side of the bottom plate and the first side plate. After sliding into place, the end face of the bottom plate in the length direction contacts the end face of the first assembly part.

[0014] It should be noted that the second assembly part protrudes beyond the first assembly part, meaning the length of the first assembly part is less than the length of the second assembly part. Because the second assembly part is closer to the cavity, a stepped groove is formed between the end face of the first assembly part and the outer surface of the second assembly part.

[0015] When assembling the panel, the outer side of the second assembly part contacts the inner side of the base plate and the first side plate. That is, the stepped groove is set on the inner side of the base plate and the first side plate. Since the base plate and the first side plate are perpendicular, and the outer side of the second assembly part contacts the inner side of the base plate and the first side plate, it can limit the panel, so that the panel can only slide along the length direction of the lower shell. When it slides to the end face of the base plate and the end face of the first assembly part, the panel can no longer slide due to the resistance and limitation between the two. At this time, the panel slides into place and can be fixed to the lower shell.

[0016] In one specific embodiment, when the second side plate of the upper housing and the assembly part of the panel slide in the height direction, the inner side surface of the second side plate and the outer side surface of the second assembly part make guide contact, and the end face of the second side plate and the end face of the first assembly part make guide contact.

[0017] It should be noted that the inner side of the second side plate contacts the outer side of the second assembly part, and the end face of the second side plate contacts the end face of the first assembly part, that is, the end face of the second side plate is located in the stepped groove. The stepped groove can limit the second side plate, so that the second side plate can only slide along the height direction of the panel. When the second side plate slides to the bottom surface and the top surface of the first side plate, due to the contact and limitation between the two, the upper shell can no longer slide. At this time, the upper shell slides into place and can be fixed to the panel and the lower shell.

[0018] In one specific embodiment, after the panel, upper housing, and lower housing are assembled and fixed, the outer side of the second assembly part is flush with the outer side of the bent plate; the outer side of the second assembly part is in contact with the inner side of the bottom plate, top plate, first side plate, and second side plate; the end face of the second assembly part is in contact with the end face of the bent plate; the outer side of the first assembly part, the outer side of the first side plate, and the outer side of the second side plate are flush; and the end face of the first assembly part is in contact with the end faces of the first side plate and the second side plate.

[0019] In one specific embodiment, the length of the bent plate is less than the length of the first side plate, and the height of the bent plate is less than the height of the first side plate.

[0020] Preferably, the length of the bent plate is 0.86 to 0.90 times the length of the first side plate, and the height of the bent plate is 0.54 to 0.58 times the height of the first side plate. Preferably, the length of the bent plate is 0.88 times the length of the first side plate, and the height of the bent plate is 0.56 times the height of the first side plate.

[0021] The length-to-height ratio of the bent plate in this invention is optimized: when the length is too short (<0.86 times), the panel assembly surface needs to be designed with a larger length, resulting in inconvenient assembly. When the height is too low (<0.54 times), the contact area between the second side plate and the bent plate is insufficient, resulting in poor guiding stability and affecting the strength of the assembled shell.

[0022] In this invention, the first side plate is provided with a certain height, allowing the second side plate and the bent plate to contact and fit together, forming a fitted support structure. This overlap between the first and second side plates enhances the structural strength of the first side plate of the lower housing and prevents deformation of the side plate during assembly or use from affecting assembly accuracy. Therefore, this invention simplifies the structure and improves assembly convenience while also considering the assembly stability and structural strength of the housing, offering the advantages of convenient assembly and reliable stability.

[0023] In one specific embodiment, the bottom of the side of the second assembly part is provided with a first screw hole, the top of the side of the second assembly part is provided with a second screw hole, and the bending plate is provided with a third screw hole; the first side plate is provided with a first through hole that matches the first screw hole, the second side plate is provided with a second through hole that matches the second screw hole and a third through hole that matches the third screw hole; the screw passes through the through hole and connects to the corresponding screw hole.

[0024] Preferably, the screw passes through the through hole and connects to the corresponding screw hole, that is, the screw passes through the first through hole and connects to the first screw hole, the screw passes through the second through hole and connects to the second screw hole, and the screw passes through the third through hole and connects to the third screw hole.

[0025] Preferably, the first through hole, the second through hole, and the third through hole have grooves to accommodate the screw head. With this design, when the screw is connected to the through hole, the outer side of the screw is flush with the outer side of the housing.

[0026] Preferably, each side of the second assembly portion of each panel is provided with a first screw hole and a second screw hole, and each panel has two sides, that is, each panel has a total of two first screw holes and two second screw holes, and the two panels have a total of four first screw holes and four second screw holes. Each bending plate is provided with two third screw holes, and the lower housing has two bending plates, with a total of four third screw holes. Therefore, when assembling the housing structure (upper housing, lower housing, and panel) of the present invention, only 12 screws need to be tightened, making the operation convenient and quick.

[0027] In one specific embodiment, the lower housing is made of metal, the bent plate and the first side plate are integrally formed by bending, and the first side plate and the bottom plate are integrally formed by bending; the upper housing is made of metal, and the second side plate and the top plate are integrally formed by bending; the panel is a panel made by injection molding.

[0028] In a second aspect, the present invention provides an electronic endoscope image processor, comprising electronic components, an intermediate plate, and a housing structure as described in any one of the first aspects, wherein the electronic components are mounted on the intermediate plate, and the intermediate plate is mounted on the bottom plate of the lower housing by bolts.

[0029] In one specific embodiment, a foot pad is also included, which is disposed on the bottom surface of the base plate, and one end of a bolt passes through the foot pad, the base plate, and the intermediate plate and is fixed by a nut.

[0030] Thirdly, the present invention also provides a method for assembling a shell structure, which is based on the shell structure of the first aspect. The method includes: Step 1: making the outer side of the second assembly part of the panel contact the inner side of the bottom plate and the first side plate, and controlling the control panel to slide along the length direction of the bottom plate. After the end face of the second assembly part contacts the end face of the bent plate and the end face of the first assembly part contacts the end face of the first side plate, the panel and the lower shell are connected; Step 2: making the inner side of the second side plate contact the outer side of the second assembly part of the panel, controlling the second side plate to slide along the height direction of the second assembly part, and after the bottom surface of the second side plate contacts the top surface of the first side plate and the inner side of the second side plate contacts the outer side of the bent plate, the upper shell, the lower shell and the panel are connected and fixed.

[0031] In step 1, the mounting portion of the panel is brought into contact with the inner side of the base plate; specifically, the outer side of the second mounting portion is brought into contact with the inner side of the base plate, and further, the outer side of the second mounting portion is brought into contact with the inner side of the first side plate. This design provides effective positioning, enabling rapid panel installation.

[0032] Preferably, the panel and the lower housing are fixed together by screws. The screws pass through the first through hole of the first side plate and connect to the first screw hole, thus initially fixing the panel and the lower housing. After the panel is initially fixed at both ends of the lower housing along its length (the left and right sides in the figure), the upper housing is installed.

[0033] In step 2, the second side plate of the upper housing is brought into contact with the assembly part of the front panel, specifically, the inner side surface of the second side plate and the outer side surface of the second assembly part are in contact, and the end face of the second side plate is in contact with the outer side surface of the first assembly part. This design provides effective positioning and enables rapid installation of the upper housing.

[0034] Preferably, the upper housing, the panel, and the lower housing are fixed together by screws. The screws pass through the second through hole of the second side plate and connect to the second screw hole of the panel to achieve initial fixation of the upper housing and the panel. The screws pass through the third through hole of the second side plate and connect to the third screw hole of the bent plate to achieve fixation between the upper housing, the lower housing, and the panel.

[0035] Fourthly, the present invention also provides an assembly method for an electronic endoscope image processor, which is based on the electronic endoscope image processor of the second aspect. The method includes: contacting the outer side of the second assembly part of the panel with the inner side of the base plate and the first side plate; sliding the control panel along the length direction of the base plate; connecting the panel and the lower housing after the end face of the assembly part of the panel contacts the end face of the first side plate and the bending plate; installing electronic components onto the intermediate plate; passing bolts from bottom to top through the through holes of the foot pad and the base plate, so that the threaded section of the bolt extends out of the upper surface of the base plate; aligning the through hole of the intermediate plate with the bolt and fitting it onto the threaded section; tightening the nut to lock the intermediate plate to the upper surface of the base plate, while clamping the foot pad to the lower surface of the base plate; contacting the inner side of the second side plate with the outer side of the second assembly part of the panel; controlling the second side plate to slide along the height direction of the second assembly part; connecting and fixing the upper housing, the lower housing, and the panel after the bottom surface of the second side plate contacts the top surface of the first side plate and the inner side of the second side plate contacts the outer side of the bending plate.

[0036] Preferably, the base plate has four elongated holes for the bolts used to install the foot pads and the intermediate plate. These holes are arranged along the length of the base plate to allow for bolt position adjustment, enabling the intermediate plate to move along the length of the base plate before fixing. This invention, by installing the front panel first and then the intermediate plate, only requires adjusting the position of the intermediate plate during installation to achieve contact between the two. If the intermediate plate is installed first and then the front panel, the position of the intermediate plate may need to be adjusted again to achieve contact. Beneficial effects

[0037] The present invention adopts a component combination design of lower shell, upper shell and panel, and the upper shell and lower shell have no complex irregular structure (the bottom plate of the lower shell is perpendicularly connected to the first side plate, and the top plate of the upper shell is perpendicularly connected to the second side plate), which makes the number of shell structure parts small and the structure simple, reducing the complexity of the manufacturing and assembly process of the shell structure. This invention employs a pre-fixed panel design combined with a sliding guide assembly, significantly reducing assembly alignment difficulty and improving assembly convenience. Specifically, during assembly, two panels are first connected to both ends of the lower housing. When assembling the panels, the assembly part of the panel forms a precise positioning surface with the end faces of the first side plate and the bent plate, enabling rapid panel assembly. When assembling the upper housing, only the second side plate of the upper housing needs to be slid along the assembly part of the panel. During the sliding process, the assembly part of the panel forms a guide trajectory, and simultaneously, with the limiting structure formed by the contact between the bottom surface of the second side plate and the top surface of the first side plate, rapid alignment and installation of the upper housing are achieved. Compared to existing solutions with no guide alignment or complex guide alignment and limiting structures, the guiding and limiting structures of this invention are more direct and simpler, enabling rapid assembly of the housing.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The purpose of this invention is to provide a housing structure for electronic devices that is simple in structure and easy to assemble, so as to reduce the material cost of housing parts and production and assembly time. Furthermore, the purpose of this invention is to provide a housing structure for an endoscope image processor that is simple in structure and easy to assemble, so as to reduce the component cost of the image processor housing and production and assembly time.

[0044] In this invention, the inner surface refers to the side closest to the center of the housing, the outer surface is the side furthest from the center of the housing, and the end face refers to the surface perpendicular to the side direction and located at the end of the part. In this invention, the length direction is... Figure 1 The x-axis is shown, the width is the y-axis, and the height is the z-axis.

[0045] A housing structure for an electronic endoscope image processor includes a lower housing 1, an upper housing 2, and a panel 3. The lower housing 1 includes a base plate 11 and first side plates 12 connected to both sides of the base plate 11 in the width direction and perpendicular to the base plate 11. A bent plate 13 is connected to the top of the inner side of the first side plate 12. The panel 3 is connected to both ends of the lower housing 1 in the length direction, and the mounting part of the panel 3 contacts the end faces of the first side plate 12 and the bent plate 13. The upper housing 2 includes a top plate 21 and second side plates 22 connected to both sides of the top plate 21 in the width direction and perpendicular to the top plate 21. The mounting parts of the second side plate 22 and the panel 3 of the upper housing 2 slide in the height direction. When the upper housing 2 slides into place, the bottom surface of the second side plate 22 contacts the top surface of the first side plate 12, and the inner side of the second side plate 22 contacts the outer side of the bent plate 13.

[0046] The present invention adopts a component combination design of lower shell 1, upper shell 2 and two panels 3, and the upper shell 2 and lower shell 1 have no complex irregular structure (the bottom plate of the lower shell is perpendicularly connected to the first side plate, the top plate of the upper shell is perpendicularly connected to the second side plate, and the shape of the upper shell and the lower shell is U-shaped), which makes the number of shell structure parts small, the structure simple, and reduces the complexity of the manufacturing and assembly process of the shell structure.

[0047] This invention employs a pre-fixed panel design combined with a sliding guide assembly, significantly reducing assembly alignment difficulty and improving assembly convenience. Specifically, during assembly, two panels are first connected to both ends of the lower housing. When assembling the panels, the assembly part of the panel forms a precise positioning surface with the end faces of the first side plate and the bent plate, enabling rapid panel assembly. When assembling the upper housing, only the second side plate of the upper housing needs to be slid along the assembly part of the panel. During the sliding process, the assembly part of the panel forms a guide trajectory, and simultaneously, with the limiting structure formed by the contact between the bottom surface of the second side plate and the top surface of the first side plate, rapid alignment and installation of the upper housing are achieved. Compared to existing solutions with no guide alignment or complex guide alignment and limiting structures, the guiding and limiting structures of this invention are more direct and simpler, enabling rapid assembly of the housing.

[0048] It should be noted that contact in this invention refers to two parts being adjacent or touching, with a gap of 0. However, due to manufacturing precision issues, there may be a slight gap (0-3mm) between the parts after assembly, which is also permissible. Example

[0049] like Figures 1 to 6 As shown, the present invention provides a shell structure, including a lower shell 1, the lower shell being U-shaped, including a bottom plate 11 and two first side plates 12 perpendicular to the bottom plate 11, the two first side plates 12 being parallel to each other, and a bent plate 13 being connected to the top of the inner side surface of the first side plate 12.

[0050] Specifically, to enable the image processor to have electromagnetic shielding capabilities, the lower housing 1 is made of metal. The lower housing 1 is manufactured using a bending process, where the base plate 11, the first side plate 12, and the bent plate 13 are formed through an integral bending process. Furthermore, the length of the bent plate 13 is less than the length of the first side plate 12, while the length of the first side plate 12 is the same as the length of the base plate 11. During manufacturing, a metal plate is first cut, and then the lower housing 1 is produced through four bending operations.

[0051] The upper housing 2 is U-shaped, including a top plate 21 and two second side plates 22 perpendicular to the bottom plate. The two second side plates 22 are parallel. In order to enable the image processor to have electromagnetic shielding function, the upper housing 2 is also made of metal. The upper housing 2 is processed by bending. Since bending is existing technology, it will not be described in this embodiment.

[0052] There are two panels 3, which are respectively connected to the two ends of the lower housing 1 along its length, and the end face of the assembly part of the panel 3 is in contact with the end face of the first side plate 12 and the bending plate 13.

[0053] During assembly, first connect the two panels 3, and then install the upper housing. Since the second side plate 22 of the upper housing 2 and the mounting part of the panel are in sliding fit, when assembling the upper housing, slide the upper housing along the mounting part of the panel, and fix the upper housing 2 after sliding it into place.

[0054] To ensure the neatness of the shell, the upper shell 2 and the lower shell 1 have the same length, and the width of the panel is the same as the width of the upper and lower shells. That is, the top plate 21, the second side plate 22, the bottom plate 11, and the first side plate 12 have the same length, and the sum of the widths of the bottom plate 11 and the first side plate 12 equals the sum of the widths of the top plate 21 and the second side plate 22, which is equal to the width of the panel. This design ensures that when the upper shell 2, the panel 3, and the lower shell 1 are connected, the outer surfaces of the first side plate 12, the second side plate 22, and the panel 3 are flush.

[0055] It should be noted that the lower housing 1 of the present invention not only has a simple structure, but also serves as a positioning element during panel installation. Specifically, the panel 3 is a box structure with one open end. This design allows a cavity to be formed inside the panel 3, and a first assembly part 31 and a second assembly part 32 are formed at the edge of the panel. Furthermore, the second assembly part 32 is located on the side closer to the cavity. When the panel 3 and the lower housing 1 are connected, the end face of the first side plate 12 contacts the end face of the first assembly part 31, forming the first limiting structure of the panel. The end face of the bent plate 13 contacts the end face of the second assembly part 32, forming the second limiting structure of the panel. The design of the assembly surfaces facilitates the limiting of the panel during installation.

[0056] Furthermore, the first assembly part 31 and the second assembly part 32 are arranged in a stepped manner, with the second assembly part 32 protruding from the first assembly part 31, meaning that the second assembly part 32 is longer in the length direction.

[0057] When the panel 3 and the lower housing 1 are assembled, they adopt a sliding fit. When the panel 3 and the lower housing 1 are connected, the outer side of the second assembly part 32 contacts the inner side of the base plate 11 and the first side plate 12, and the panel can slide along the contact surface. After the panel 3 and the lower housing 1 are connected, the end face of the base plate 11 contacts the end face of the first assembly part 31, forming the third limiting structure of the panel.

[0058] The present invention, through the sliding fit design of panel 3 and lower housing 1 and the three limiting structures of panel 3, facilitates the alignment and assembly of panel 3 on the one hand, and limits the panel 3 on the other hand, enabling rapid alignment and assembly of panel 3.

[0059] After panel 3 is installed, upper housing 2 is installed, and the second side plate 22 of upper housing 2 and the assembly part of panel 3 are slidably engaged. Specifically, the outer side of the first assembly part 31 and the end face of the second assembly part 32 form the sliding limiting part of the upper housing. When upper housing 2 is installed, the inner side of the second side plate 22 of upper housing 2 contacts the outer side of the second assembly part 32, the end face of the second side plate 22 contacts the end face of the first assembly part 31, and the second side plate 22 can slide up and down along the sliding limiting part (i.e., slide along the height direction), realizing the quick alignment and assembly of upper housing 2. When upper housing 2 is moved into place, the top surface of the first side plate 12 and the bottom surface of the second side plate 22 contact each other, forming the limiting structure of upper housing 2.

[0060] After the panel 3, the upper shell 2 and the lower shell 1 are connected, the outer side of the second assembly part 32 is flush with the outer side of the bending plate 13; the outer side of the second assembly part 32 is in contact with the inner side of the bottom plate 11, the top plate 21, the first side plate 12 and the second side plate 22, and the end face of the second assembly part 32 is in contact with the end face of the bending plate 13; the outer side of the first assembly part 31, the outer side of the first side plate 12 and the outer side of the second side plate 22 are flush with each other; the end face of the first assembly part 31 is in contact with the end faces of the first side plate 12 and the second side plate 22.

[0061] The present invention uses the sliding limiting part formed on the panel 3 in conjunction with the limiting structure of the upper shell formed between the upper shell and the lower shell to facilitate the alignment and assembly of the upper shell 2, and to limit the upper shell 2, thereby enabling the rapid alignment and assembly of the upper shell 2.

[0062] Typically, the main unit's casing panels (front and rear panels) have multiple openings for connecting the electronic mirror, USB, HDMI, and power interfaces, and these panels often have a curved design. Using metal components is difficult to process, challenging to design, and costly. Therefore, in this invention, panel 3 is manufactured using injection molding. Furthermore, to achieve electromagnetic shielding for the image processor, conductive paint is applied to the areas of the plastic panel that come into contact with the metal casing, creating a conductive path between the panel and the upper and lower casings, thus achieving electromagnetic shielding for the image processor. Moreover, all inner surfaces of the casing and panels are unpainted metal or coated with conductive metal paint. This creates a robust metal shielding space within the main unit, ensuring good electromagnetic interference and electromagnetic immunity.

[0063] It should be noted that the assembly part of panel 3 is provided with a screw hole structure, which includes a pre-embedded insert. Since panel 3 is manufactured using injection molding, directly creating screw holes in the plastic part and using self-tapping screws for tightening would not only easily cause cracking at the screw holes due to the radial force of the screw tightening, but also easily lead to stripping failure of the plastic screw holes after repeated assembly and disassembly, making effective tightening impossible. In this embodiment, during the injection molding of panel 3, a metal pre-embedded insert (preferably a copper nut) is embedded into the side of the second assembly part 32, forming the first and second screw holes. During assembly, the screw engages with the threaded metal pre-embedded insert, achieving a detachable connection between panel 3 and the lower housing 1 and upper housing 2. This design improves the wear resistance of the screw holes and the reliability of the connection.

[0064] In this invention, the lower housing 1, upper housing 2, and panel 3 are assembled and fixed by screws. Specifically, the bottom of the side of the second assembly part 32 is provided with a first screw hole, the top of the side of the second assembly part 32 is provided with a second screw hole, and the bent plate 13 is provided with a third screw hole; the first side plate 12 is provided with a first through hole that matches the first screw hole, and the second side plate 22 is provided with a second through hole that matches the second screw hole and a third through hole that matches the third screw hole; the screws pass through the first through hole, the second through hole, and the third through hole respectively and are connected to the corresponding first screw hole, second screw hole, and third screw hole. This invention has four first screw holes, four second screw holes, and four third screw holes, and the assembly of the housing structure can be completed with a total of 12 screws, which has the advantages of simple assembly and convenient operation. Example 2 Example 2 is based on the same inventive concept as Example 1, and the parts that are repeated in Example 1 will not be described in this example.

[0065] like Figures 1 to 8 As shown, during the assembly of the electronic endoscope image processor housing, in addition to the assembly between the housing structures, it is also necessary to assemble its internal electronic components, such as the image processor motherboard 6, transformer, and switching power supply 7. These components are secured inside the housing with screws. Typically, they are directly fixed to the lower housing with screws. This connection method requires adding a certain number of screw holes to the lower housing, which not only affects the overall aesthetics of the lower housing's outer surface but also impacts the assembly efficiency. Therefore, this invention adds an intermediate plate 5 with screw holes and screw posts to secure these electronic components.

[0066] Specifically, such as Figure 6 As shown, the image processor motherboard 6, transformer, and switching power supply 7 are mounted on the intermediate board 5 using screw posts.

[0067] Furthermore, since the image processor motherboard 6 and the switching power supply 7 also have electronic components on their reverse sides, direct contact with the metal intermediate plate could cause short circuits and other malfunctions. Therefore, the screw posts are designed with a certain height to prevent the electronic components on the reverse sides of the image processor motherboard 6 and the switching power supply 7 from contacting the metal intermediate plate 5. The height of the screw posts only needs to ensure that the electronic components on the reverse sides of the image processor motherboard 6 and the switching power supply 7 do not contact the metal base plate, and the length of the screw posts can be set to 3-5cm.

[0068] To ensure the stability of the main unit, four feet 4 were designed. The four heightening feet 4 are set on the lower shell and protrude from the lower shell, which can stabilize the placement. At the same time, it can also prevent the lower shell from directly contacting the table. Prolonged contact and friction with the table will cause the insulating paint on the outer surface of the lower shell to wear off, resulting in the outer shell not being insulated and increasing the risk of electric shock when touched by a person.

[0069] It is worth noting that the foot pad 4 and the intermediate plate 5 are locked together by the same bolt. Specifically, the bolt passes through the foot pad 4, the bottom plate 11 of the lower housing, and the intermediate plate 5, and is connected to the bolt by a nut, thereby locking the intermediate plate 5 and the foot pad 4 together.

[0070] Four elongated holes 111 are provided on the base plate 11 for the bolts of the mounting feet 4 and the intermediate plate 5 to pass through. The elongated holes are arranged along the length of the base plate so that the position of the bolts can be adjusted, so that the intermediate plate 5 can be moved along the length of the base plate 11 before being fixed. Example

[0071] like Figures 1 to 6 As shown, based on the shell structure of Embodiment 1, this embodiment provides an assembly method for the shell structure; the method includes the following steps. Step 1: Make the assembly part of the panel 3 contact the inner side of the base plate 11, slide the control panel 3 along the length direction of the base plate 11, and connect the panel 3 and the lower shell 1 after the assembly part of the panel 3 contacts the end face of the first side plate 12 and the bending plate 13.

[0072] Furthermore, the panel 3 and the lower housing 2 are fixed together by screws. The screws pass through the first through hole of the first side plate 12 and connect to the first screw hole, achieving initial fixing of the panel and the lower housing. At both ends of the lower housing ( Figure 1 After the panels 3 are initially fixed on both sides (as shown), the upper housing 2 is installed.

[0073] It should be noted that only 4 screws are needed to initially fix the two panels 3. Since the panels 3 and the lower housing 2 can be quickly aligned, it only takes 2 to 3 minutes to initially fix the two panels 3.

[0074] Step 2: Make the second side plate 22 of the upper housing 2 and the assembly part of the panel 3 come into contact, and control the second side plate 22 to slide along the height direction of the panel assembly part. When the bottom surface of the second side plate 22 comes into contact with the top surface of the first side plate 12 and the inner side surface of the second side plate 22 comes into contact with the outer side surface of the bent plate 13, connect the upper housing 2, the lower housing 1 and the panel 3.

[0075] Furthermore, the upper housing 2, the panel 3, and the lower housing 1 are fixed together by screws. The screws pass through the second through hole of the second side plate 22 and connect to the second screw hole of the panel 3 to achieve the initial fixation of the upper housing 2 and the panel 3. The screws pass through the third through hole of the second side plate 22 and connect to the third screw hole of the bent plate 13 to achieve the fixation between the upper housing 2, the lower housing 1, and the panel 3.

[0076] It should be noted that fixing the panel 3 and initially fixing the upper housing 2 only requires tightening 4 screws. When placing the upper housing 2, simply slide it along the mounting part of the panel 3 and the lower housing can limit its position, so the upper housing 2 can be quickly aligned. Therefore, fixing the panel 3 and initially fixing the upper housing 2 only takes 2 to 3 minutes.

[0077] The fixing between the upper shell 2, the lower shell 1 and the panel 3 also only requires tightening 4 screws. Since no alignment or other operations are required at this time, only tightening the screws is needed, so this process takes about 2 minutes.

[0078] In summary, the assembly method for the shell structure provided by this invention requires only 6 to 8 minutes to assemble the entire shell.

[0079] The patent with announcement number CN221264278U includes the following: basic frame assembly (connecting the bottom plate and front box plate to the U-shaped bottom shell with screws, and clamping the rear box plate to the rear side of the U-shaped bottom shell), front panel installation (inserting the limiting plate of the front panel into the slot and supporting it on the slide plate, with the protruding plate of the front lower connecting plate extending out from the clearance hole and bolted to the bottom plate), and enveloping cover plate installation (covering the top cover plate of the enveloping cover plate on the upper right connecting plate, the upper front connecting plate, and the upper rear connecting plate, with the buckle extending into the buckle slot, pushing the enveloping cover plate to the left until the right cover plate is attached to the right side plate, the bottom cover plate abutting against the right side of the bottom plate, the clamping plate clamping the upper left connecting plate, and connecting the right cover plate to the right side plate and the bottom cover plate to the bottom plate with screws). The connection process requires multiple positioning adjustments (such as inserting the limiting plate into the slot, the buckle engaging the buckle slot, and the clamping plate fixing the upper left connecting plate). The overall assembly time is between 16 and 20 minutes.

[0080] The patent with announcement number CN213525037U includes panel assembly pre-assembly (the touch screen is inserted into the mounting frame in the middle of the panel from the rear, and is fixed by limiting blocks and clamping plates, with function buttons installed on the side), partition installation (the partition is installed on the screw posts on the rear side of the panel, the folded plates on both sides of the partition are installed inside the front end of the base by screws, and the protruding block and notch are positioned), base and panel connection (the panel is connected and fixed on the folded plates on both sides of the front end of the base), shell installation (the shell is inserted into the base from the rear end of the base through the sliding grooves on both sides, and the tongue is inserted into the slot on the partition), and back cover installation (the back cover is inserted into the folded plates on both sides of the rear end of the base through the slot and is fixed by screws, and the support is fixed on the back cover). The assembly time is between 15-18 minutes. Even if the assembly time of the touch screen is removed, the assembly time is still 12-15 minutes.

[0081] Compared with the shell assembly structure in the prior art, the assembly structure and assembly method provided by the present invention significantly shorten the assembly time. Example

[0082] like Figures 1 to 8 As shown, based on the electronic endoscope image processor provided in Embodiment 2, this embodiment provides an assembly method for an electronic endoscope image processor. The method specifically includes: Step 1: Making the assembly part of the panel 3 contact the inner surface of the base plate 11; sliding the control panel 3 along the length of the base plate 11; connecting the panel 3 and the lower housing 1 after the assembly part of the panel 3 contacts the end faces of the first side plate 12 and the bent plate 13; Step 2: Installing electronic components onto the intermediate plate 5; passing bolts from bottom to top through the foot pads 4 and the through holes of the base plate 11, so that the bolts... The threaded section extends out of the upper surface of the base plate 11. Align the through hole of the intermediate plate 5 with the bolt and fit it onto the threaded section. Tighten the nut to lock the intermediate plate 5 onto the upper surface of the base plate 11. At the same time, clamp the foot pad 4 onto the lower surface of the base plate 11. Step 3: Make the second side plate 22 of the upper housing 2 and the assembly part of the panel 3 come into contact. Control the second side plate 22 to slide along the height direction of the panel assembly part. When the bottom surface of the second side plate 22 contacts the top surface of the first side plate 12 and the inner side surface of the second side plate 22 contacts the outer side surface of the bent plate 13, connect the upper housing 2, the lower housing 1 and the panel 3.

[0083] In this invention, the order of steps 1 and 2 can be interchanged. However, performing step 1 first, then step 2, and then step 3 can save assembly time for the electronic endoscope image processor.

[0084] Specifically, to ensure the imaging quality of the image processor, it needs to have electromagnetic shielding. Grounding wires are installed on the image processor motherboard 6 and the switching power supply 7 on the intermediate board 5, and these grounding wires are connected to the metal intermediate board 5. Since there is a certain height gap between the intermediate board 5 and the base plate 11, they are not in direct contact. Therefore, the intermediate board 5 needs to be connected to the front panel 3 to ground the image processor motherboard 6 and the switching power supply 7. This invention uses a method of installing the front panel 3 first and then the intermediate board 5, which facilitates adjusting the position of the front panel 3 and allows for quick contact between the intermediate board 5 and the front panel 3.

[0085] Specifically, four elongated holes 111 are provided on the base plate 11 for the bolts of the mounting feet 4 and the intermediate plate 5 to pass through. These holes are arranged along the length of the base plate to allow for bolt position adjustment, enabling the intermediate plate 5 to move along the length of the base plate 11 before fixing. This invention, by installing the panel 3 first and then the intermediate plate 5, only requires adjusting the position of the intermediate plate 5 during installation to achieve contact between the intermediate plate 5 and the panel 3. If the intermediate plate 5 is installed first and then the panel 3, the position of the intermediate plate 5 may need to be adjusted again to achieve contact.

[0086] Compared to Embodiment 3, this embodiment adds the steps of installing the intermediate plate 5 (on which the image processor motherboard 6, switching power supply, and transformer are mounted) and the feet 4. Since the intermediate plate 5 and feet 4 share four identical bolts, the installation time is approximately 3-4 minutes (approximately 3 minutes for the four bolts and approximately 1 minute for adjusting the intermediate plate position). Installing the image processor motherboard 6, switching power supply, and transformer on the intermediate plate takes approximately 5-7 minutes. The total installation time for the entire image processor is approximately 13-18 minutes, which significantly reduces the assembly time compared to existing image processor assembly methods.

[0087] Through the above design, the present invention has the following advantages: Simple structure and low manufacturing difficulty: The present invention adopts a minimalist part combination design of lower shell 1, upper shell 2 and two panels 3. Both lower shell 1 and upper shell 2 are U-shaped metal structures, which are integrally formed by bending. There are no complex irregular structures. The panels are injection molded parts. The manufacturing process of each component is simple, which greatly reduces the manufacturing cost of the shell.

[0088] Precise positioning and high assembly efficiency: The stepped assembly part of the panel 3 and the bending plate 13 of the lower shell 1 form a multi-positioning structure. Both the panel 3 and the upper shell 2 adopt a sliding fit assembly method. During the sliding process, a precise guide trajectory is formed, eliminating the need for multiple positioning and alignment. The overall assembly of the shell takes only 6 to 8 minutes, and the assembly of the whole machine takes only 13 to 18 minutes, which significantly improves the assembly efficiency compared with the existing technology.

[0089] High structural strength and good assembly stability: The bent plate fits and supports the second side plate, so that the first side plate and the second side plate form an overlapping support structure, which enhances the structural strength of the shell side plate and avoids the side plate deformation during assembly or use from affecting the assembly accuracy.

[0090] Reliable connection and long service life: The panel assembly part is pre-embedded with copper nuts with ring anti-slip texture, which solves the problem that plastic parts are easily cracked by screws when directly drilled with screw holes and stripped after repeated disassembly and assembly.

[0091] The electromagnetic shielding effect meets the usage requirements: Through the design of metal shell + conductive paint on the panel + metal intermediate plate, a closed electromagnetic shielding cavity and a complete grounding path are formed, which meets the electromagnetic compatibility standards of electronic endoscope image processors and effectively avoids the impact of electromagnetic interference on image processing effect.

[0092] High safety in use: The foot pads and the middle plate adopt an integrated locking design, which not only reduces the number of bolts, but also avoids direct contact between the lower shell and the tabletop, preventing leakage caused by wear of the insulating paint on the outer side of the shell, thus improving the safety of the equipment; the elongated hole on the bottom plate allows for adjustment of the position of the middle plate, facilitating quick grounding and reducing debugging difficulty.

[0093] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
