Detailed Implementation

[0022] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] This application provides an endoscope main unit chassis, see reference. Figure 1 and Figure 2 As shown, the main unit chassis includes a mounting frame 100 and a movable cover 300. The mounting frame 100 includes a first end 110 and a second end 120 arranged along a first direction, with the first end 110 and the second end 120 disposed opposite to each other. The movable cover 300 is slidably connected to the mounting frame 100, and the movable cover 300 can slide along the first direction from the second end 120 toward the first end 110 to cover at least a portion of the opening area of ​​the mounting frame 100, thereby abutting with the mounting frame 100 to form a receiving cavity 200 for accommodating the main unit components.

[0026] The movable cover 300 slides with the mounting frame 100, making it easier for the operator to adjust the position of the movable cover 300. By sliding the movable cover 300, the position of the movable cover 300 on the mounting frame 100 can be quickly adjusted to the preset position, so that the movable cover 300 and the mounting frame 100 are aligned. This facilitates the subsequent connection of the movable cover 300 and the mounting frame 100 with connectors, quickly completing the assembly of the movable cover 300 and the mounting frame 100, saving assembly time and improving assembly efficiency.

[0027] Since the movable cover plate 300 and the mounting frame 100 are slidably connected, it helps to reduce the moving resistance of the movable cover plate 300. It is easier to adjust the position of the movable cover plate 300, install or remove the movable cover plate 300, and make it easier to disassemble and assemble the movable cover plate 300. To a certain extent, it can improve the disassembly and assembly efficiency of the movable cover plate 300, making the disassembly and assembly of the movable cover plate 300 more convenient.

[0028] The mounting frame 100 is a frame structure with a hollow interior and openings. When the movable cover 300 is assembled, it needs to cover and block the openings of the mounting frame 100, sealing the interior of the mounting frame 100 to a certain extent. This forms a receiving cavity 200 by mating with the mounting frame 100. The receiving cavity 200 is used to house the host device, which can be an electronic component or other parts that need to be installed inside the host. The mounting frame 100 and the movable cover 300 protect the host device within the receiving cavity 200, reducing the impact of external factors on the host device.

[0029] In some specific embodiments, the main unit is typically installed inside the mounting frame 100 first, and then the movable cover 300 is assembled. The movable cover 300 is slidably connected to the mounting frame 100, and can be quickly removed if the main unit inside the receiving cavity 200 needs to be repaired, thereby improving repair efficiency to a certain extent.

[0030] In some embodiments, the movable cover 300 can cover the entire opening area of ​​the mounting frame 100, improving the sealing of the receiving cavity 200. In other embodiments, the movable cover 300 can also cover only a portion of the opening area of ​​the mounting frame 100.

[0031] refer to Figure 2As shown, the first direction can be referenced to the direction indicated by the x-axis and the direction indicated by the dashed arrow. When assembling the movable cover plate 300, the movable cover plate 300 slides in the direction indicated by the dashed arrow. The first end 110 and the second end 120 of the mounting frame 100 are the two ends of the mounting frame 100, respectively. The first end 110 and the second end 120 are arranged along the first direction, and the movable cover plate 300 can slide from the first end 110 to the second end 120, and also slide from the second end 120 to the first end 110.

[0032] In some embodiments of this application, reference is made to Figure 4 and Figure 5 As shown, a portion of the mounting frame 100 is bent to form a groove 130. The extension direction of the groove 130 is parallel to the first direction, and a portion of the movable cover plate 300 is slidably disposed within the groove 130. The movable cover plate 300 slides within the groove 130 along the extension direction of the groove 130. The groove 130 restricts the movement direction of the movable cover plate 300 to ensure that the movable cover plate 300 can slide along a preset direction.

[0033] Furthermore, the movable cover 300 is positioned to engage with the slide groove 130 in the depth direction of the chassis to prevent the movable cover 300 from detaching from the mounting frame 100. The depth direction of the chassis is perpendicular to the first direction. The depth direction of the chassis can be referenced... Figures 2 to 4 The z-axis direction in the coordinate system shown. The movable cover plate 300 slides relative to the mounting frame 100 along the first direction. At the same time, the slide groove 130 can limit the movable cover plate 300 to prevent it from detaching from the mounting frame 100 during the sliding process, thereby improving the sliding stability of the movable cover plate 300.

[0034] The slide groove 130 is formed by bending a portion of the mounting frame 100. On the one hand, this simplifies the structure of the mounting frame 100 and avoids the situation where the slide groove 130 is added to the mounting frame 100, making the structure of the mounting frame 100 more complex. On the other hand, bending a portion of the mounting frame 100 can, to a certain extent, improve the overall strength of the mounting frame 100, increase the pressure-bearing range of the mounting frame 100, and improve the structural strength of the host chassis.

[0035] The movable cover plate 300 includes a web plate 320 and two flanges 310 respectively installed at both ends of the web plate 320. (See reference) Figure 6 and Figure 8 As shown, two wing plates 310 are arranged facing each other, and the edges of the wing plates 310 away from the web plate 320 are bent to form a bent portion 330. The extending direction of the bent portion 330 is parallel to a first direction, and the bent portion 330 is slidably mounted on the slide groove 130. The first direction is... Figure 6 and Figure 8The x-axis is shown in the diagram. The bent portion 330 is formed by bending the edge of the wing plate 310, which makes processing easier. In other embodiments, the bent portion 330 may also be formed by bending the middle part or other non-edge position of the wing plate 310.

[0036] The movable cover plate 300 includes a web plate 320 and two flanges 310. The two flanges 310 are arranged facing each other. When the movable cover plate 300 slides on the mounting frame 100, the two flanges 310 are clamped on both sides of the mounting frame 100, which can improve the stability of the sliding connection between the movable cover plate 300 and the mounting frame 100. The arrangement direction of the two flanges 310 can be referenced. Figure 6 and Figure 8 In the direction indicated by the y-axis, the two wing plates 310 restrict the movement of the movable cover plate 300 along the y-axis. Furthermore, the edges of the two wing plates 310 are bent to form bent portions 330. The two bent portions 330 are installed in the corresponding slide grooves 130 and are limited by the slide grooves 130, restricting the movement of the movable cover plate 300 in the z-axis direction. The limiting action of the two wing plates 310 and the slide grooves 130 ensures that the movable cover plate 300 can only move along the first direction, i.e., the x-axis, on the mounting frame 100, thereby improving the sliding stability of the movable cover plate 300.

[0037] In some preferred embodiments, the wing plate 310 and the web plate 320 of the movable cover plate 300 are both formed by bending the same sheet material. Using the same sheet material to form the web plate 320 and the wing plate 310 improves the ease of processing the movable cover plate 300 and correspondingly increases the structural strength of the bent sheet material.

[0038] A further preferred embodiment includes a second mounting hole 331 in the bent portion 330, as shown in the reference section. Figures 6 to 8 As shown, the second mounting hole 331 is used to mate with the connector to fix the movable cover plate 300 to the mounting frame 100. The connector directly contacts the bent portion 330, which can improve the connection stability between the bent portion 330 and the mounting frame 100.

[0039] Mounting frame 100 may be provided with mounting holes corresponding to the second mounting hole 331. The connector passes through the second mounting hole 331 and extends into the mounting hole, and is threadedly connected to the mounting frame 100, thereby fixing the movable cover plate 300 to the mounting frame 100. The second mounting hole 331 may also be a threaded hole structure, with the connector threadedly connected to the movable cover plate 300 and extending into the mounting hole. The connector may be plugged into or threadedly connected to the mounting frame 100. Alternatively, mounting frame 100 may not have mounting holes corresponding to the second mounting hole 331, and the connector may be directly pressed against the surface of the mounting frame 100 after being threadedly connected to the movable cover plate 300, increasing the friction between the movable cover plate 300 and the mounting frame 100.

[0040] The sliding path of the movable cover plate 300 on the mounting frame 100 is limited. In some preferred embodiments, a corresponding stop structure can be provided between the movable cover plate 300 and the mounting frame 100. The stop structure can prevent the movable cover plate 300 from continuing to slide along the first direction from the second end 120 to the first end 110. When the movable cover plate 300 is prevented from continuing to slide towards the first end 110 by the stop structure, the movable cover plate 300 is exactly aligned with the mounting frame 100, so that the movable cover plate 300 automatically finds the installation position during the sliding assembly process, further improving the assembly efficiency of the movable cover plate 300.

[0041] refer to Figure 8 As shown, the movable cover plate 300 includes a third end 340 and a fourth end 350 arranged along a first direction. At least one of the third end 340 and the fourth end 350 is provided with a stop portion 360. When the mounting frame 100 and the movable cover plate 300 are mated to form a receiving cavity 200, the stop portion 360 is in a limiting fit with the mounting frame 100 to prevent the movable cover plate 300 from sliding toward the first end 110. Preferably, the stop portion 360 is formed by bending a portion of the movable cover plate 300, which is easier to process.

[0042] During the sliding process of the movable cover plate 300 relative to the mounting frame 100, part of the mounting frame 100 is located on the moving path of the stop part 360. The stop part 360 abuts against the mounting frame 100, preventing the movable cover plate 300 from continuing to slide, and the movable cover plate 300 slides to the limit position.

[0043] Either the third end 340 or the fourth end 350 is the front end of the movable cover 300, and the other is the rear end of the movable cover 300. The front end of the movable cover 300 refers to the end that first contacts the mounting frame 100 when the movable cover 300 is assembled to the mounting frame 100, and the rear end refers to the end that contacts the mounting frame 100 later. Whether the stop 360 is installed at the third end 340 or the fourth end 350, it can cooperate with the mounting frame 100 to prevent the movable cover 300 from sliding further.

[0044] After the movable cover plate 300 slides into place, the assembly personnel will use connectors to connect the movable cover plate 300 and the mounting frame 100 to fix their positions.

[0045] In some preferred embodiments, reference Figure 8As shown, the stop portion 360 is provided with a first mounting hole 361, which is used to cooperate with the connector to fix the movable cover plate 300 to the mounting frame 100. The connector passes through the first mounting hole 361 and is inserted into the mounting frame 100, or the connector passes through the first mounting hole 361 and abuts against the mounting frame 100, thus fixing the movable cover plate 300 to the mounting frame 100 and fixing their relative positions. The connection method between the connector and the first mounting hole 361 is similar to the connection method between the connector and the second mounting hole 331.

[0046] By directly providing the first mounting hole 361 on the stop portion 360, the position of the stop portion 360 can be further fixed, ensuring its stability to the greatest extent possible, thereby guaranteeing the stability of the movable cover plate 300. Furthermore, when the movable cover plate 300 is slid into position, the stop portion 360 and the mounting frame 100 are in contact. Providing the first mounting hole 361 directly on the stop portion 360, due to the contact between the stop portion 360 and the mounting frame 100, can improve the fixing effect of the connector between the stop portion 360 and the mounting frame 100 to a certain extent.

[0047] The connectors can be common connection structures such as bolts and screws.

[0048] And / or, when the mounting frame 100 and the movable cover 300 are mated to form a receiving cavity 200, the third end 340 is disposed near the first end 110, the fourth end 350 is disposed near the second end 120, and the stop portion 360 is installed on the fourth end 350. The host chassis provided in this application embodiment also includes a buffer layer 400, which is mounted on the mounting frame 100 and located on the sliding path of the movable cover 300. When the mounting frame 100 and the movable cover 300 are mated to form a receiving cavity 200, the third end 340 abuts against the buffer layer 400.

[0049] The third end 340 of the movable cover plate 300 is tightly fitted against the buffer layer 400 fixed to the mounting frame 100, and the fourth end 350 of the movable cover plate 300 is tightly fitted against the mounting frame 100 through the stop part 360. Both ends of the movable cover plate 300 are indirectly fitted against the mounting frame 100, and both ends of the movable cover plate 300 are restricted, further determining the installation position of the movable cover plate 300.

[0050] Furthermore, the buffer layer 400 has a certain buffering effect, which can dissipate some of the impact caused by the sliding of the movable cover plate 300, and prevent the movable cover plate 300 from being deformed or damaged during assembly. At the same time, the buffer layer 400 has a certain degree of elasticity and can deform under external force, which can compensate for the assembly error between the movable cover plate 300 and the mounting frame 100 to a certain extent. This ensures that both ends of the movable cover plate 300 are tightly abutted against the mounting frame 100, and that the movable cover plate 300 can be stably installed on the mounting frame 100.

[0051] In some preferred embodiments, reference Figure 6 and Figure 7 As shown, the area where the end face of the third end 340 contacts the inner wall of the movable cover plate 300 is rounded. The area where the end face of the third end 340 contacts the outer wall of the movable cover plate 300 is also rounded. The rounded area between the end face and the wall has fewer sharp edges, which reduces the probability of stress concentration at the contact point with the buffer layer 400 when it is pressed against the buffer layer 400, thus lowering the risk of damage to the buffer layer 400.

[0052] And / or, the end face of the portion of the third end 340 corresponding to the web 320 of the movable cover plate 300 expands inward toward the movable cover plate 300 to increase the end face area of ​​the third end 340. Increasing the end face area of ​​the third end 340 increases the contact area between the end face of the third end 340 and the buffer layer 400, thereby reducing the force per unit area on the buffer layer 400 and reducing the probability of damage to the buffer layer 400. Simultaneously, when assembling the movable cover plate 300, the web 320 is the main stress-bearing part, and the impact on this part is greater than that on the wing plate 310. Expanding the end face area of ​​the third end 340 corresponding to the web 320 can, to a certain extent, enhance the structural strength of this portion of the third end 340, further reducing the possibility of structural damage to the third end 340.

[0053] In some embodiments of this application, the chassis further includes a panel 500, as shown in the reference. Figures 1 to 4 As shown, panel 500 is mainly used to install operating components such as display screen and buttons. The display screen can show relevant operating information of the host. Before assembling the movable cover 300, panel 500 is pre-installed to one end of mounting frame 100 or one end of movable cover 300. In this way, after assembling movable cover 300 to mounting frame 100, the entire chassis can be assembled.

[0054] When panel 500 is mounted on mounting frame 100, panel 500 can be fixed to either the first end 110 or the second end 120. In some preferred embodiments, panel 500 is fixed to the first end 110 of mounting frame 100 to reduce the impact of panel 500 on the sliding assembly process of movable cover 300. Furthermore, a buffer layer 400 can be placed between panel 500 and movable cover 300 to reduce the impact force on panel 500 during assembly of movable cover 300.

[0055] When the panel 500 is installed on the movable cover plate 300, the panel 500 can be used as a stop part 360. During the sliding assembly of the movable cover plate 300, when the panel 500 comes into contact with the mounting frame 100, the panel 500 prevents the movable cover plate 300 from continuing to slide.

[0056] In other embodiments, the chassis does not include the panel 500, and the display screen, buttons and other operating components can be directly mounted on the outer surface of the mounting frame 100.

[0057] This application also provides an endoscope host, including the endoscope host chassis provided in any of the above embodiments.

[0058] Some embodiments of this application also provide an endoscope device, including the endoscope host provided in any of the above embodiments. During use, the endoscope is plugged into the endoscope host chassis and connected to the electronic components inside the chassis. The endoscopes involved in the embodiments of this application can be bronchoscopes, pyeloscopes, esophagoscopes, gastroscopes, colonoscopes, otoscopes, rhinoscopes, oral endoscopes, laryngoscopes, colposcopes, laparoscopes, arthroscopes, etc., and this application does not specifically limit the type of endoscope.

[0059] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
