[0002] In various fields such as industrial logistics, autonomous driving, and intelligent robots, visual recognition devices are frequently used for image acquisition to improve the automation level of operations.

[0003] Industrial cameras are commonly used devices for image data acquisition. In practical applications, industrial cameras are often equipped with USB interfaces (serial interface buses) to achieve quick and convenient electrical connections with external cables. However, when external cables are electrically connected to the USB interface (serial interface bus) of industrial cameras, the sealing and waterproofing of the electrical connection points cannot be guaranteed, which limits the application range and quality of use of industrial cameras.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0026] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0027] Industrial cameras are commonly used devices for image data acquisition. In practical applications, industrial cameras are often equipped with USB interfaces (serial interface buses) to achieve quick and convenient electrical connections with external cables. However, when external cables are electrically connected to the USB interface (serial interface bus) of industrial cameras, the sealing effect of the electrical connection points cannot be guaranteed, which limits the application range and quality of use of industrial cameras.

[0028] The Type-C interface is a USB interface (serial bus) form factor standard that is smaller than Type-A and Type-B. This interface has no reversible orientation and can be plugged in either way. It can be used in PCs (master devices) as well as external devices (slave devices, such as mobile phones).

[0029] As one embodiment of this utility model, an industrial camera is disclosed, see appendix. Figures 1 to 7The device includes a housing 11, a motherboard assembly 12, a serial bus interface 13, and an external cable 20. The housing 11 has a mounting cavity, and the motherboard assembly 12 and the serial bus interface 13 are disposed within the mounting cavity. An external connection hole 15 is formed on the housing 11, penetrating the side wall of the housing 11. The motherboard assembly 12 is electrically connected to the serial bus interface 13. One end of the serial bus interface 13 is inserted into the external connection hole 15. One end of the external cable is inserted into the external connection hole 15 and electrically connected to the serial bus interface 13. One end of the external cable 20 is inserted into the external connection hole 15 and electrically connected to the serial bus interface 13. A sealing structure is formed at the mating part of the external cable 20 and the housing 11, and the sealing structure is located outside the electrical connection part between the external cable 20 and the serial bus interface 13.

[0030] The industrial camera in this embodiment also includes an image sensor module 17 (see Appendix). Figure 1 (As shown).

[0031] In this embodiment, the housing 11 of the industrial camera is provided with an external connection hole 15. The motherboard assembly 12 inside the housing 11 and the external cable 20 are electrically connected through a serial bus interface 13 provided in the external connection hole 15. In this embodiment, the type of serial bus interface 13 is not specifically limited. In actual settings, the serial bus interface 13 can be set to at least one of Type A, Type B, and Type C.

[0032] In this embodiment, the external cable 20 and the serial bus interface 13 are electrically connected by being inserted into the external hole 15. In this embodiment, the mating part of the external cable 20 and the outer shell 11 forms a sealing structure located outside the electrical connection part between the external cable 20 and the serial bus interface 13. Since the sealing structure is located outside the electrical connection part between the external cable 20 and the serial bus interface 13, during operation, the sealing structure can protect the electrical connection part between the external cable 20 and the serial bus interface 13, achieving a dustproof and waterproof effect.

[0033] This embodiment does not specifically limit the connection form between the external cable 20 and the housing 11. In actual installation, the external cable 20 can be simply plugged into the housing 11, or other connection structures can be set at the same time as plugging in, such as setting a snap-fit ​​structure, threaded connection structure, adhesive, etc. between the housing 11 and the external cable 20 to improve the reliability of the connection between the external cable 20 and the housing 11.

[0034] This embodiment does not specifically limit the form of the sealing structure. For example, in actual installation, the sealing structure can be set as a surface seal, a line seal, or other sealing forms.

[0035] Furthermore, the sealing structure in this embodiment can be set inside the wiring hole (in which case the sealing structure can be formed between the inner sidewall of the wiring hole) or outside the wiring hole (in which case the sealing structure can be formed between the outer sidewall of the housing 11), as long as it can provide sealing protection for the electrical connection between the external cable 20 and the serial bus interface 13.

[0036] In this embodiment, the specific method of forming the sealing structure is not limited. In actual installation, it can be formed by sealing ring, sealing gasket, sealant or other forms.

[0037] This embodiment features a sealing structure on the outer part of the electrical connection between the external cable 20 and the serial bus interface 13. Compared to related technologies where there is no dedicated seal at the serial bus interface 13, this effectively broadens the application scenarios of industrial cameras, providing comprehensive dustproof and short-term water immersion protection, ensuring stable operation of the camera in harsh industrial environments such as dusty and humid conditions. Furthermore, compared to some structures that improve protection by using a dedicated protective cover on the outside of the camera body 10, the sealing structure in this embodiment is directly mounted on the camera (achieving a better sealing effect through its own structure), which greatly reduces the overall size of the device and improves its adaptability to different application scenarios.

[0038] As one embodiment of this utility model, see the appendix. Figure 2 , 3 The sealing structure is formed between one end of the external cable 20 inserted into the external hole 15 and the inner sidewall of the external hole 15.

[0039] In this embodiment, the external connection hole 15 includes a first hole segment 151 and a second hole segment 152 distributed along its axial direction. One end of the first hole segment 151 communicates with the mounting cavity, and the second hole segment 152 is disposed outside the first hole segment 151. One end of the serial bus interface 13 is inserted into the first hole segment 151, and one end of the external cable 20 passes through the second hole segment 152 and is inserted into the first hole segment 151 to be electrically connected to the serial bus interface 13. The external cable 20 forms a seal with the inner sidewall of the second hole segment 152.

[0040] In this embodiment, the external connection hole 15 includes at least two structural segments (a first segment 151 and a second segment 152). That is, the external connection hole 15 has a certain length along the axial direction. The first segment 151 is located on the inner side and communicates with the mounting cavity, while the second segment 152 is located on the outer side. Thus, the first segment 151 can serve as the mounting hole for the serial bus interface 13, and the second segment 152 can serve as the mounting hole for guiding the insertion of the external cable 20 and forming a sealing structure with the external cable 20. The multi-segment structure of the external connection hole 15 allows for a more reasonable distribution of the mounting structure, provides more operating space for installation, and allows for a reasonable arrangement of the sealing structure, thereby improving the sealing effect.

[0041] To ensure the reliability of the electrical connection between the external cable 20 and the serial bus interface 13, as well as the stability of the sealing structure, a first connection hole 1141 is provided on the outer wall of the outer shell 11 in one embodiment of the present invention. The first connection hole 1141 is located on one side of the external hole 15. The external cable 20 includes a body part 21 and a plug part 22. The plug part 22 protrudes from the mating surface of the body part 21. The plug part 22 passes through the second hole segment 152 and is inserted into the first hole segment 151 to be electrically connected to the serial bus interface 13. A seal is formed between the outer wall of the plug part 22 and the inner wall of the second hole segment 152. A second connection hole 211 is formed on the body part 21. The first connection hole 1141 and the second connection hole 211 are opposite to each other and are used to be fixedly connected by a connector.

[0042] In this embodiment, corresponding first connecting hole 1141 and second connecting hole 211 are respectively provided on the outer casing 11 and the body 21 of the external cable 20. In the actual assembly process, the external cable 20 and the outer casing 11 can be fixedly connected by a connector that passes through both the first connecting hole 1141 and the second connecting hole 211. See attached drawing. Figure 1 The external cable 20 and the outer casing 11 are connected by two connecting screws 24. In actual installation, the two connecting screws 24 can be symmetrically arranged on both sides of the body 21 of the external cable 20 to improve the reliability of the connection.

[0043] As one embodiment of this utility model, see the appendix. Figures 1 to 7A first protruding boss 114 is formed on the outer side wall of the outer shell 11. The external connection hole 15 penetrates the first boss 114. The first connection hole 1141 is provided on the mating surface of the first boss 114. The second connection hole 211 is provided on the mating surface of the body part 21. The mating surface of the first boss 114 and the mating surface of the body part 21 are opposite to each other and fit together. A second protruding boss 23 is formed on the mating surface of the body part 21. The insertion part 22 penetrates the second boss 23. The second boss 23 is used to insert into the second hole segment 152. A seal is formed between the outer side wall of the second boss 23 and the inner side wall of the second hole segment 152.

[0044] The first boss 114 in this embodiment can increase the thickness of the outer shell 11 at the opening of the external hole 15, so that the external hole 15 has a larger axial length, and can also increase the strength of the outer shell 11 at the opening.

[0045] For actual installation, please refer to the appendix. Figure 3 The mating surface of the main body 21 fits snugly with the mating surface of the first protrusion 114, which can limit the insertion position of the external cable 20. Furthermore, in this embodiment, a second protrusion 23 is formed on the main body 21. The second protrusion 23 can be inserted into the external connection hole 15, and a seal is formed between the second protrusion 23 and the inner wall of the external connection hole 15, which can improve the sealing effect. In actual installation, a clearance fit, a transition fit, or an interference fit can be used between the outer wall of the second protrusion 23 and the inner wall of the external connection hole 15.

[0046] As one embodiment of this utility model, see the appendix. Figure 3 An annular sealing groove is formed on the outer side wall of the second boss 23. The industrial camera also includes a first sealing member 161, which is sleeved in the sealing groove. The outer side of the first sealing member 161 protrudes from the sealing groove and abuts against the inner side wall of the second hole section 152.

[0047] In this embodiment, a sealing groove is provided on the outer side wall of the second boss 23. The sealing groove is used to install the first sealing member 161. When the external cable 20 is inserted into the external hole 15, under the action of the sealing groove and the mating surface of the body part 21, the first sealing member 161 is not easy to detach from the second boss 23 due to the obstruction of the end edge of the external hole 15. This allows the first sealing member 161 to be more conveniently and stably positioned between the second boss 23 and the inner side wall of the external hole 15, thereby achieving a better sealing effect.

[0048] This embodiment does not specifically limit the depth and shape of the sealing groove. In actual installation, it can be reasonably designed according to different styles of the first sealing element 161. For example, when the first sealing element 161 is an O-ring, the cross-section of the sealing groove can be set as arc or rectangle.

[0049] As one embodiment of this utility model, see the appendix. Figure 3 The second hole segment 152 includes a first end connected to the first hole segment 151 and a second end opposite to the first end. The second hole segment 152 is constructed as a tapered structure with the diameter of the second end being larger than the diameter of the first end.

[0050] In this embodiment, the second hole segment 152 is set as a conical structure. During the insertion process of the external cable 20 into the outer casing 11, the conical second hole segment 152 can guide the external cable 20, making it easier for the insertion part 22 of the external cable 20 to align with the external hole 15. It also makes it easier to prevent the first seal 161 from falling off during the insertion process. In addition, the conical design also helps to compress the first seal 161, achieving a better sealing effect.

[0051] As one embodiment of this utility model, see the appendix. Figure 3 The industrial camera also includes a second seal 162, which is disposed between the outer side wall of the serial bus interface 13 and the inner side wall of the external connection hole 15, and is used to seal the mating part of the serial bus interface 13 and the external connection hole 15.

[0052] In this embodiment, the serial bus interface 13 and the external connection hole 15 of the industrial camera are fitted with a second sealing element 162 at the insertion and mating part (first hole segment 151). The second sealing element 162 can seal the mating part between the external connection hole 15 and the serial bus interface 13, and can provide waterproof and dustproof protection for the camera body 10 in the non-working state. When in the working state, the first sealing element 162 seals the outside of the electrical connection part between the serial bus interface 13 and the external cable 20. In this embodiment, the industrial camera can provide a good sealing effect on the external connection hole 15 of the serial bus interface 13 in both working and non-working states, thereby enabling the industrial camera to adapt to more application scenarios.

[0053] It should be noted that the serial bus interface 13 in this embodiment has waterproof performance. In actual use, when not in operation, there is no need to add a structure similar to a waterproof cap to the serial bus interface 13 to achieve the waterproof performance of the industrial camera under the action of the second seal 162.

[0054] In this embodiment, the second sealing element 162 can be a double-peak sealing ring as shown in the attached figure, which can achieve a better sealing effect.

[0055] As one embodiment of this utility model, see the appendix. Figure 1 The outer casing 11 includes a front cover 111, a middle frame 112, and a rear cover 113 connected in sequence. The front cover 111, the middle frame 112, and the rear cover 113 together define the mounting cavity. The front cover 111 and the middle frame 112, and the middle frame 112 and the rear cover 113 are respectively sleeved and sealed together. The external connection hole 15 is provided on the rear cover 113.

[0056] In this embodiment, the connecting parts between the front cover 111, the middle frame 112, and the rear cover 113 in the outer shell 11 are all provided with sealing elements (third sealing element and fourth sealing element 164). By setting the middle frame 112 as a cylindrical structure, it is only necessary to set the sealing elements at the connecting parts at both ends of the middle frame 112. Of course, in actual installation, the middle frame 112 and one of the front cover 111 or the rear cover 113 can also be set as an integral structure. For example, if the middle frame 112 and the front cover 111 are set as an integral structure, it is only necessary to connect it to the rear cover 113 during assembly. This can reduce the number of connecting parts, and correspondingly reduce the number of sealing elements, thus making it easier to achieve a seal.

[0057] In this embodiment, a front sealing platform is provided at the rear end of the front cover 111, and a rear sealing platform is provided on the rear cover 113. During assembly, the middle frame 112 forms a surface contact fit with the front and rear sealing platforms, improving the stability of the fit. Moreover, the sidewalls of the front and rear sealing platforms are convenient for setting annular sealing grooves for installing the corresponding third and fourth sealing elements 164, achieving circumferential sealing of the connection parts. When setting the sealing groove, the width of the sealing groove can be set to be slightly smaller than the width of the corresponding sealing element. This way, when the sealing element is installed in the corresponding sealing groove, there will be a certain pre-pressure, reducing the problem of the sealing element easily detaching from the sealing groove, and making the installation of the sealing element more stable.

[0058] In actual design, in order to ensure a better sealing effect, multiple corresponding third and fourth sealing elements 164 can be set at the corresponding joint parts to achieve multiple sealing.

[0059] Of course, it is conceivable that in actual design, the sealing structure of the connection parts of multiple components on the outer shell 11 is not limited to the sealing through the third and fourth sealing elements 164 mentioned above. Other forms of sealing structures can also be set, such as end face sealing.

[0060] As one embodiment of this utility model, see the appendix. Figure 1 , 2The rear end face of the rear cover 113 has a plug mounting hole that passes through the mounting cavity. The plug assembly 14 includes a plug body 141 and a fifth sealing member 142. The plug body 141 is inserted into the plug mounting hole. The fifth sealing member 142 is provided on the outer wall of the plug body 141 and the inner wall of the plug mounting hole to seal the plug mounting hole.

[0061] In this embodiment, the interface is connected to the external cable via the plug assembly 14, which is more convenient for setting up a sealed structure compared to the structure of the network port connection in related technologies.

[0062] In this embodiment, the plug assembly 14 includes a plug body 141 and a fifth sealing element 142. As shown in the attached figure, during specific installation, a sealing groove for installing the fifth sealing element 142 can be provided on the outer wall of the plug body 141. The fifth sealing element 142 is embedded in the corresponding sealing groove and is pressed against the inner wall of the plug mounting hole to form a sealing effect.

[0063] In this embodiment, the plug assembly 14 can be selected with different specifications of aviation plugs as needed, such as M8 and M12 aviation plugs.

[0064] As one embodiment of this utility model, see the appendix. Figure 1 , 2 4. The rear cover 113 includes a rear cover body 113 and a plug mounting cylinder 1132. The plug mounting cylinder 1132 protrudes from the rear end face of the rear cover body 113. The rear end face of the rear cover body 113 is provided with the plug mounting hole. The plug mounting cylinder 1132 forms an insertion channel with an insertion port. The plug mounting hole and the insertion channel are interconnected. One end of the plug body 141 extends into the insertion channel. A gap is formed between the inner wall of the plug mounting channel and the outer wall of the plug body 141. The gap is used to accommodate an external connector. An annular groove and a protruding annular support platform are formed on the inner wall of the plug mounting cylinder 1132. One end face of the annular support platform faces the insertion port and is connected to the side of the annular groove. The plug assembly 14 also includes a sixth sealing member 143. The sixth sealing member 143 is disposed in the annular groove, and one end abuts against the end face of the annular support platform facing the insertion port, and is used to abut against the end of the external connector inserted into the gap to form a seal.

[0065] In this embodiment, the plug assembly 14 and the rear cover 113 form a double sealing effect (a fifth seal 142 and a sixth seal 143). The fifth seal 142 is a normal seal (the sealing effect is always present), while the sixth seal 143 only produces a sealing effect when it is connected to an external connector and is squeezed by the external connector. The external connector can be a plug cable 31 or a plug waterproof cap 32 (the plug body 141 can be sealed by the plug waterproof cap 32 when the camera is not in operation). This can effectively ensure the sealing effect of the plug in both the working and non-working phases.

[0066] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
