[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0034] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
[0035] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of components in a specific posture (as shown in the figures).

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.
[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0037] An endoscope system typically includes an endoscope light source unit, a beam guide, an endoscope, a camera, a camera unit, a display, communication cables, and a housing assembly. One end of the beam guide connects to the endoscope light source unit, and the other end connects to the endoscope. The endoscope light source unit provides light to the endoscope. One end of the camera is attached to the endoscope to acquire the endoscope's optical signals for imaging, while the other end communicates with the camera unit to transmit the image signal for processing, and finally, it is displayed on the monitor.
[0038] An endoscope is a testing instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It has a wide range of applications and is used in complex environments. The endoscope main unit housing, as the main component that protects and supports the endoscope system, plays an important role in the endoscope system.
[0039] In existing technologies, endoscope main unit housings are mostly produced using stamping dies. CNC stamping of endoscope main unit housings typically requires multiple processes such as bending and welding, resulting in significant dimensional tolerances in the mating positions of the main unit housing due to the cumulative errors of each process. This often leads to problems such as poor assembly accuracy and high unit cost. Therefore, improving the assembly accuracy of CNC stamped main unit housings and reducing unit cost is a pressing technical problem that needs to be solved by those skilled in the art.
[0040] The purpose of this application is to overcome the defects and deficiencies in the prior art and provide an endoscope main unit housing. This endoscope main unit housing aims to solve many problems in the production of endoscope housings, such as structural welding, high welding difficulty, large welding errors, and inconvenient operation.
[0041] like Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of the endoscope host of this application. The endoscope host 1 includes an endoscope host housing 10 and a functional module component 20. The functional module component 20 is located inside the endoscope host housing 10. A beam guide interface 300 and a button module 301 are also provided on the front shell 30. The beam guide interface 300 and the button module 301 are located on the side of the front shell 30 away from the endoscope host housing 10. The button module 301 and the beam guide interface 300 are arranged adjacent to each other. The beam guide interface 300 communicates with the functional module component 20 and realizes the endoscope function outward through the beam guide interface 300. In this application, the endoscope host 1 can be, but is not limited to, a light source host, a camera host, or an integrated machine, etc.
[0042] The endoscope housing 10 plays a crucial role in protection, support, and fixation. However, in existing technologies, the front and bottom shells of endoscopes are typically connected by welding, resulting in high difficulty in splicing and welding. To facilitate the disassembly and maintenance of the endoscope housing, this application provides an endoscope housing 10, such as... Figure 2 As shown, Figure 2This is an exploded structural diagram of an embodiment of the endoscope main unit housing of this application. The endoscope main unit housing 10 includes: a first housing 11, a second housing 12, and a third housing 13, at least the first housing 11, the second housing 12, and the third housing 13 together form a cavity; wherein one end of the second housing 12 and the third housing 13 are respectively connected to the first housing 11; in some embodiments, the third housing 13 includes a third plate 130, a fourth plate 131, and a fifth plate 132, the fourth plate 131 and the fifth plate 132 are located on both sides of the third plate 130, wherein the fourth plate 131 and the fifth plate 132 are respectively connected to the two sides of the third plate 130, thereby forming a cylindrical cavity inside the third housing 13 and the second housing 12, and the first housing 11 covers one side opening of the cylindrical cavity formed by the third housing 13 and the second housing 12, and is respectively connected to the second housing 12 and the third housing 13.
[0043] like Figure 2 As shown, in order to simultaneously ensure a secure connection between the first housing 11 and the second housing 12, and also facilitate easy disassembly between them, the first housing 11 includes a front shell 30, a first plate 110, and a first connecting arm 111. The first connecting arm 111 extends from the first side of the first plate 110 toward the cavity. The second housing 12 includes a second plate 120 and a second connecting arm 121. The second connecting arm 121 extends from the second plate 120 toward the cavity, and the extending directions of the first connecting arm 111 and the second connecting arm 121 intersect, connecting the first connecting arm 111 and the second connecting arm 121. In this embodiment, the first connecting arm 111 and the first housing 11 are integrally formed, and the second connecting arm 121 and the second housing 12 are integrally formed. The connecting surfaces of the first connecting arm 111 and the second connecting arm 121 face the fourth plate 131 and the fifth plate 132. The first connecting arm 111 is provided with a first connecting hole 1110, and the second connecting arm 121 is provided with a second connecting hole 1210. The first connecting hole 1110 and the second connecting hole 1210 are overlapped and connected. The first connecting hole 1110 and the second connecting hole 1210 are then connected by an external connector, which can be, but is not limited to, screws, pins, etc. This arrangement of the first connecting hole 1110 and the second connecting hole 1210 allows the external connector to connect the first connecting arm 111 and the second connecting arm 121 from outside the first housing 11 and the second housing 12, thereby connecting the first housing 11 and the second housing 12, avoiding the problems of complex structure and difficult installation in the prior art.
[0044] When the first connecting arm 111 and the second connecting arm 121 are connected, positioning is required to ensure that each external connector corresponds to the connecting hole. To meet the positioning requirements of the first connecting arm 111 and the second connecting arm 121, as follows: Figure 3 As shown, Figure 3 yes Figure 2 A partial structural diagram of the endoscope main unit housing is shown in the embodiment. In some embodiments, one of the first connecting arm 111 and the second connecting arm 121 has a pin 1211 and the other has a slot 1111. The pin 1211 and the slot 1111 are snapped together and positioned after the first housing 11 and the second housing 12 are brought close to each other. In this embodiment, the slot 1111 is located on the first connecting arm 111, and the pin 1211 is located on the second connecting arm 121. The pin 1211 extends into the cavity, and its extension direction is perpendicular to the plane defined by the intersection of the extension directions of the first connecting arm 111 and the second connecting arm 121. The plane of the first connecting arm 111 is perpendicular to the pin 1211. The opening of the slot 1111 is located on the side of the first connecting arm 111 facing the pin 1211, and the side wall of the slot 1111 away from the second plate 120 is recessed to form a positioning groove 1111a. The pin 1211 falls into the positioning groove 1111a through the opening of the slot 1111. The pin 1211 and the slot 1111 mainly play a role in pre-positioning during the assembly process. The weight of the first housing 11 allows the pin 1211 to be inserted into the positioning groove 1111a of the slot 1111 and locked in place by gravity. This allows the first connecting hole 1110 and the second connecting hole 1210 on the first connecting arm 111 and the second connecting arm 121 to be aligned and corrected during connection, and it is not easy for deviation to occur.
[0045] like Figure 2 As shown, in order to further strengthen the connection between the first housing 11 and the second housing 12 and enable the first housing 11 and the second housing 12 to be connected in multiple directions, the first housing 11 also includes a third connecting arm 112. The third connecting arm 112 extends from the second side of the first plate 110 toward the cavity. The third connecting arm 112 and the side of the second plate 120 facing the cavity are fixedly connected by an external operation method. In some embodiments, the second plate 120 is provided with a third connecting hole 1200, and the third connecting arm 112 is provided with a fourth connecting hole 1120. The third connecting hole 1200 and the fourth connecting hole 1120 are overlapped and connected. The third connecting hole 1200 and the fourth connecting hole 1120 are then connected by an external connector. The external connector may be, but is not limited to, screws, pins, etc. The third connecting hole 1200 and the fourth connecting hole 1120 can also be positioned simultaneously after the pin 1211 and the slot 1111 are pre-positioned during the assembly process, thereby achieving precise connection between the third connecting hole 1200 and the fourth connecting hole 1120.
[0046] like Figure 4 and Figure 5 As shown, Figure 4 yes Figure 2 An exploded view of the endoscope main unit housing of an embodiment, from another perspective. Figure 5 yes Figure 2 An exploded view of an embodiment of the endoscope main unit housing shows that, in order to connect the third housing 13 and the first housing 11, the third plate 130 is provided with a first connector 1300 on the side facing the cavity, and the fourth plate 131 and the fifth plate 132 are provided with a second connector 1310 and a third connector 1320 on the side facing the cavity. The first housing 11 also includes a fourth connecting arm 113, which extends from the third side of the first plate 110 toward the cavity. The fourth connecting arm 113 is engaged with the first connector 1300, the second connector 1310 is engaged with the non-connecting surfaces of the first connecting arm 111 and the second connecting arm 121, and the third connector 1320 is engaged with the non-connecting surfaces of the first connecting arm 111 and the second connecting arm 121. The non-connecting surfaces refer to the two surfaces of the first connecting arm 111 and the second connecting arm 121 that are not connected. In some embodiments, the fourth connecting arm is integrally formed with the first housing 11. The fourth connecting arm 133 is a metal arm extending into the depth of the cavity. The first connecting member 1300 is a snap-fit structure. There may be one or more first connecting members 1300 on the third plate 130. The snap-fit opening faces the extension direction of the fourth connecting arm 113. The fourth connecting arm 113 is provided with a snap-fit feature 1130. The snap-fit structure and the snap-fit feature 1130 are tightly snapped together, thereby tightly connecting the third housing 13 and the first housing 11 in the third side direction. In this embodiment, the snap-fit feature may be, but is not limited to, a positioning groove. Thus, the first connecting member 1300 not only serves a connecting function but also a positioning function. After positioning using the snap-fit feature, it is then fixed with an external connecting member, thereby strengthening the connection.
[0047] like Figure 5 As shown, in some embodiments, the second connector 1310 and the third connector 1320 are snap-fit structures. There may be one or more second connectors 1310 and third connectors 1320 on the fourth plate 131 and the fifth plate 132. The snap-fit openings face the first connecting arm 111 and the second connecting arm 121. The non-connecting surfaces of the first connecting arm 111 and the second connecting arm 121 have engaging features 1130. The snap-fit features and engaging features 1130 engage tightly, thereby tightly connecting the third housing 13 and the first housing 11 in the first side direction. The second connector 1310 and the third connector 1320 not only strengthen the connection between the first housing 11 and the third housing 13, but also press the first connecting arm 111 and the second connecting arm 121, thereby strengthening the connection between the first connecting arm 111 and the second connecting arm 121. Figure 6 As shown, Figure 6 yes Figure 2 An exploded view of the endoscope main unit housing of an embodiment is shown. The second housing 12 is a single-plate housing, while the third housing 13 is a three-plate housing. To maintain the integrity of the cavity formed by the second housing 12 and the third housing 13, and to ensure a secure connection between them for easy installation, a first guide 1201 and a second guide 1202 are provided at the edge of the side of the second plate 120 facing away from the cavity. Both the first guide 1201 and the second guide 1202 are guide grooves. A first sliding member 1311 is provided at the end of the fourth plate 131 away from the third plate 130, and a second sliding member 1321 is provided at the end of the fifth plate 132 away from the third plate 130. The first guide 1201 and the first sliding member 1311 are in sliding engagement, as are the second guide 1202 and the second sliding member 1321. In some embodiments, the first guide 1201 and the second guide 1202 are recessed guide rails that are recessed towards the cavity, while the first slider 1311 and the second slider 1321 are a smooth transition bending structure formed by the fourth plate 131 and the fifth plate 132 bending towards the second plate 120 in the height direction of the fourth plate 131 and the fifth plate 132. In some embodiments, the smooth transition bending structure may be, but is not limited to, a slider. The first slider 1311 and the second slider 1321 match the groove shape of the first guide 1201 and the second guide 1202, so that the third housing 13 can be slidably sleeved onto the second housing 12 by the first slider 1311 and the second slider 1321.
[0048] Only the first guide 1201 cooperates with the first slider 1311, the second guide 1202, and the second slider 1312. Because the guide is a guide groove, the slider may deviate from its track when sliding, causing installation jamming. Therefore, this application also adds a bracket inside the guide to support the sliding of the first slider 1311 and the second slider 1312. Figure 6 and Figure 7 As shown, Figure 7 yes Figure 2The schematic diagram of the bracket structure in the embodiment shows that, in some embodiments, a bracket 1203 is provided inside the first sliding member 1311 and the second sliding member 1321. The portion of the bracket 1203 closest to the first sliding member 1311 and the second sliding member 1321 is a sliding connection portion 1203a. The bracket 1203 can be, but is not limited to, a U-shaped structure bracket protruding in the middle towards the second plate 120. This U-shaped structure bracket is fixed to the concave surface of the grooves in the first sliding member 1311 and the second sliding member 1321 by screws. The protruding portion in the middle of the U-shaped structure bracket is provided with the sliding connection portion 1203a. The first sliding member 1311 and the second sliding member 1321 are provided with a fixing part 1333. The sliding connection part 1203a can provide a supporting force when the first sliding member 1311 and the second sliding member 1321 slide in, so that the first sliding member 1311 and the second sliding member 1321 will not get stuck due to sliding offset when they slide in. On the other hand, when the third housing 13 is fully slid in, the first sliding member 1311 and the second sliding member 1321 can be fixed to the U-shaped structure bracket by means of screws or pins, thereby further fixing the second housing 12 and the third housing 13.
[0049] like Figure 4 As shown, the endoscope main unit housing 10 also includes a fourth housing 14. The fourth housing 14 is disposed in the opening direction of the cavity formed by the first housing 11, the second housing 12, and the third housing 13, and is connected to the other end of the second housing 12 and the third housing 13 respectively. The second housing 12 also includes a fifth connecting arm 140. The third housing 13 also includes a sixth connecting arm 133, which is fixedly connected to the side of the fourth housing 14 facing the cavity. The fifth connecting arm 140 is fixedly connected to the sixth connecting arm 133 of the third housing 13 and the side of the fourth housing 14 facing the cavity. The fifth connecting arm 140 and the sixth connecting arm 133 are provided with positioning holes. The fourth housing 14 is provided with a positioning pin on the side facing the cavity. The positioning pin is connected and positioned with the positioning hole to connect the second housing 12, the third housing 13, and the fourth housing 14. Thus, the second housing 1212 and the fourth housing 1414 are connected, and the fixed connection is made from the side of the fourth housing 1414 away from the cavity. In some embodiments, the fifth connecting arm 140 and the fourth housing 14 are provided with a fifth connecting hole 1400 and a sixth connecting hole 1401, which are fixed by means of pins or the like. At the same time, a sixth connecting arm 133 is also provided on the side where the third housing 13 is connected to the fourth housing 14. The sixth connecting arm 133 is connected to the fifth connecting arm 140 and the fourth housing 14 to form a fixed linkage, thereby strengthening the connection between the second housing 12, the third housing 13 and the fourth housing 14.
[0050] Through the precise arrangement between each housing, there is a simple and clear installation method that is easy to operate and disassemble. In some embodiments, the installation method of each housing may be, but is not limited to, first connecting the first connecting arm 111 and the second connecting arm 121 of the first housing 11 and the second housing 12, and then pre-positioning them during the assembly process by means of the pin 1211 and the slot 1111. Then, the third connecting arm 112 is fixedly connected to the side of the second plate 120 facing the cavity by means of operation from the outside of the outer shell, thereby further connecting the first housing 11 and the second housing 12. The third housing 13 is then slidably connected to and fixed to the second housing 12 via the first sliding member 1311 and the second sliding member 1321, and guided by the first guide member 1201 and the second guide member 1202 of the second housing 12. The third housing is then snapped into the first housing 11 via the first connector 1300, the second connector 1310 and the third connector 1320. This achieves the connection between the first housing 11, the second housing 12 and the third housing 13. Finally, the fourth housing is placed over the opening direction of the cavity formed by the first housing 11, the second housing 12 and the third housing 13 and fixed, thereby forming a cavity enclosed by six sides, forming the endoscope main unit housing 10 of this application.
[0051] The endoscope main unit housing provided in this application has a reasonable arrangement of the positional relationship of the first housing, the second housing, and the third housing, so that the first housing and the second housing intersect through the extension direction of the first connecting arm and the second connecting arm, thereby allowing the modules between the housings to be assembled in sequence, which is convenient for maintenance.
