Figure 4 yes Figure 3 Cross-sectional view of AA; Figure 5 yes Figure 4 Enlarged structural diagram of region A in the middle; Figure 6 yes Figure 3 Cross-sectional view of BB; Figure 7 yes Figure 4 A magnified structural diagram of region B in the middle. (See diagram below.) Figures 1 to 7 As shown, the serial port protection structure 100 includes a protective cover 110 and a waterproof component 120; a fastening part 111 for fastening with the industrial equipment is provided along the edge of the protective cover 110, and the protective cover 110 has a slot 112; the waterproof component 120 fits into the slot 112 to close the slot 112; wherein, the protective cover 110 is made of a rigid material, and the waterproof component 120 is made of a flexible material.

[0023] Specifically, the industrial equipment can be a frequency converter, control cabinet, or other device with a communication interface 200. The industrial equipment can include any interactive device that needs to communicate with external devices, such as an industrial equipment keyboard 1000. The industrial equipment keyboard 1000 can include a communication interface 200 and a serial port protection structure 100. The communication interface 200 is fixed on the housing of the industrial equipment keyboard 1000, and the serial port protection structure 100 covers the communication interface 200 to seal the communication interface 200, thereby improving the overall protection performance of the industrial equipment.

[0024] A rigid protective ring 210 can be installed around the communication interface 200. This rigid protective ring 210 is designed to work in conjunction with the waterproof component 120 to enhance protective performance. The rigid protective ring 210 is arranged in a ring around the communication interface 200, and its shape and size perfectly match the gaps around the interface. This precisely limits the sealing area to critical areas of the interface prone to dust / water ingress, achieving precise protection. The rigid structure provides sufficient structural strength for the rigid protective ring 210, allowing it to maintain its shape and prevent bending or deformation under conditions of vibration, minor impacts, or frequent opening and closing of the serial port cover that industrial equipment may encounter. The rigid protective ring 210 can be a raised ring positioned around the communication interface 200.

[0025] The serial port protection structure 100 may include a protective cover 110 and a waterproof component 120. The protective cover 110 and the waterproof component 120 are made of different materials. The protective cover 110 is made of rigid material, while the waterproof component 120 is made of flexible material. For example, the protective cover 110 may be made of hard plastic, and the waterproof component 120 may be made of foam material and attached and fixed to the groove 112 of the protective cover 110 by adhesive; or it may be made of soft plastic material and connected to the protective cover 110 by two-color plastic molding.

[0026] The protective cover 110 may have a fastening part 111 and a groove 112. A waterproof component 120 is attached to the groove 112, and the groove 112 can be sealed by the waterproof component 120. The protective cover 110 also has multiple fastening parts 111 for connecting with industrial equipment to fix the protective cover 110 to the housing of the industrial equipment. When the protective cover 110 is fixed by the fastening parts 111, the rigid rubber protective component 210 exerts concentrated pressure on the waterproof component 120. Because the ribs are raised rigid structures, the pressure is concentrated on the contact line between the rigid rubber protective component 210 and the waterproof component 120, rather than being dispersed over a wide surface. This concentrated compression causes reliable deformation of the waterproof component 120, filling the tiny gaps between the rigid rubber protective component 210 and the protective cover 110, ultimately forming a seamless sealing barrier that effectively prevents dust, moisture, and other impurities from entering the interface, solving the defect of insufficient pressure in existing narrow-edge space structures that leads to water ingress.

[0027] As a further embodiment, the protective cover 110 includes a first connecting portion 113 and a second connecting portion 114 disposed opposite to each other at both ends; both the first connecting portion 113 and the second connecting portion 114 are provided with the fastening portion 111, and both the first connecting portion 113 and the second connecting portion 114 are connected to the housing of the industrial equipment through the fastening portion 111.

[0028] The protective cover 110 may include a first connecting portion 113 and a second connecting portion 114, which are disposed opposite to each other at both ends of the protective cover 110. For example, the first connecting portion 113 may be disposed at the left or right end of the protective cover 110, and the second connecting portion 114 may be disposed at the right or left end of the protective cover 110. Taking the first connecting portion 113 disposed at the right end of the protective cover 110 and the second connecting portion 114 disposed at the left end of the protective cover 110 as an example, a fastening portion 111 may be provided on at least one side of the first connecting portion 113 and at least one side of the second connecting portion 114. The fastening portion 111 is used to fasten with the housing of the industrial equipment keyboard 1000 to achieve a fixed connection. For example, the fastening portion 111 may be provided on the left side of the first connecting portion 113 and the right side of the second connecting portion 114, or fastening portions 111 may be provided on both sides of the first connecting portion 113 and both sides of the second connecting portion 114.

[0029] As a further embodiment, the first connecting portion 113 is provided with at least one groove 115, and the first connecting portion 113 forms a first fixing portion 1131 and a second fixing portion 1132 through the groove 115, and both the first fixing portion 1131 and the second fixing portion 1132 are provided with the fastening portion 111.

[0030] The first connecting portion 113 may have a groove 115 that divides it into two parts: a first fixing portion 1131 and a second fixing portion 1132. Both the first fixing portion 1131 and the second fixing portion 1132 are provided with a fastening portion 111. For example, the groove 115 may be provided in the middle region of the first connecting portion 113, dividing it into upper and lower parts. The upper part is the first fixing portion 1131, and the lower part is the second fixing portion 1132. Fastening portions 111 are provided on the outer sides of both the first fixing portion 1131 and the second fixing portion 1132. The groove 115 can give the first fixing part 1131 and the second fixing part 1132 a certain deformation capability. During assembly, the fastening part 111 on the first fixing part 1131 can be connected to the housing of the industrial equipment keyboard 1000 first, and then the fastening part 111 on the second fixing part 1132 can be connected to the housing of the industrial equipment keyboard 1000, thereby improving the convenience of assembly.

[0031] As a further embodiment, the first connecting part 113 is provided with two grooves 115, and the first connecting part 113 forms a first fixing part 1131, a second fixing part 1132 and an intermediate part 1133 through the two grooves 115. The first fixing part 1131 and the second fixing part 1132 are both provided with the fastening part 111.

[0032] Two grooves 115 can be formed on the first connecting part 113, dividing the first connecting part 113 into three parts: a first fixing part 1131, a second fixing part 1132, and a middle part 1133. Figure 1 As shown, there is a groove 115 between the first fixing part 1131 and the middle part 1133, and a groove 115 between the middle part 1133 and the second fixing part 1132. Similarly, a fastening part 111 is provided on the outer side of both the first fixing part 1131 and the second fixing part 1132. By increasing the number of grooves 115, the elastic deformation capability of the first fixing part 1131 and the second fixing part 1132 can be further improved. During assembly, when the protective cover 110 is pushed by external force, the first fixing part 1131 and the second fixing part 1132 will undergo slight shrinkage deformation due to the grooves. Without precise alignment or excessive external force, they can be easily connected to the housing of the industrial equipment keyboard 1000. After assembly, the first fixing part 1131 and the second fixing part 1132 will return to their original shape and form a tight snap-fit ​​connection with the mounting hole 220 on the housing of the industrial equipment keyboard 1000. This avoids the problems of difficult assembly and easy breakage of traditional rigid structures, thereby simplifying the assembly operation. In addition, when the equipment is in industrial scenarios such as vibration or slight collision, the first fixing part 1131 and the second fixing part 1132, which have elastic deformation capabilities, can adapt to small displacements and always maintain a tight connection with the mounting hole 220 to prevent the protective cover 110 from shifting.

[0033] As a further embodiment, the fastening portion 111 is provided on the outer side of both the first fixing portion 1131 and the outer side of the second fixing portion 1132.

[0034] In this design, a fastening part 111 can be provided on the outer side of the first fixing part 1131 and the outer side of the second fixing part 1132. That is, the first fixing part 1131 has a fastening part 111, the second fixing part 1132 has a fastening part 111, and the first connecting part 113 has two fastening parts 111, which can improve the stability when assembling with the housing of the industrial equipment keyboard 1000.

[0035] As a further embodiment, a limiting part 116 is provided on the side of the first fixing part 1131 or the second fixing part 1132 facing the industrial equipment.

[0036] The first fixing part 1131 or the second fixing part 1132 may be provided with a limiting part 116 on the side facing the communication interface 200. For example, the limiting part 116 may be provided on the side of the first fixing part 1131 facing the communication interface 200. The limiting part 116 may be close to the outside of the first fixing part 1131, that is, the limiting part 116 may be provided adjacent to the fastening part 111.

[0037] The limiting part 116 serves two purposes: limiting the movement and controlling the rotation angle of the protective cover 110. Figure 2 As shown, after the protective cover 110 is assembled, it can be slightly rotated about one end as an axis to switch between a semi-open state and a closed state. For example, it can be slightly rotated about the first fixing part 1131 and the second fixing part 1132 as an axis. During the rotation, the limiting part 116 can be engaged in a specific position of the limiting groove 230 on the housing of the industrial equipment keyboard 1000 to prevent the protective cover 110 from continuing to open, thereby controlling the rotation angle.

[0038] As a further embodiment, at least one side of the second connecting portion 114 is provided with the fastening portion 111.

[0039] The second connecting portion 114 may have a fastening portion 111 on at least one side. For example, the fastening portion 111 may be provided on the upper or lower side of the second connecting portion 114. Preferably, the fastening portion 111 may be provided on both sides of the second connecting portion 114. The fastening portion 111 on the second connecting portion 114 is used to achieve a fixed connection with the housing of the industrial equipment keyboard 1000. When the fastening portion 111 of the second connecting portion 114 is fastened to the housing of the industrial equipment keyboard 1000, the communication interface 200 is in a closed state. When the fastening portion 111 of the second connecting portion 114 is disconnected from the housing of the industrial equipment keyboard 1000, the communication interface 200 is in an open state.

[0040] The protective cover 110 has a notch at one end where it connects to the first connecting part 113 and the second connecting part 114. This notch facilitates the installation and removal of the fastening parts 111 of the first connecting part 113 and the second connecting part 114. Furthermore, after the fastening part 111 of the first connecting part 113 is fastened to the housing of the industrial equipment keyboard 1000, the fastening pressure between the protective cover 110 and the housing of the industrial equipment keyboard 1000 can be adjusted by adjusting the height of the fastening part 111 of the second connecting part 114 within the housing of the industrial equipment keyboard 1000.

[0041] As a further embodiment, the protective cover 110 is made of hard plastic, and the waterproof component 120 is made of soft plastic.

[0042] Among them, the protective cover 110 is made of rigid material, and the waterproof component 120 is made of flexible material. For example, the protective cover 110 can be made of hard plastic, and the waterproof component 120 can be made of soft plastic. When the hard plastic protective component 210 squeezes the waterproof component 120, it can make the waterproof component 120 fit tightly with the communication interface 200.

[0043] This utility model also provides an industrial device, which includes a housing and a communication interface 200 fixed on the housing. The communication interface 200 is surrounded by a hard plastic protective member 210, and the communication interface 200 is covered by the serial port protection structure 100 as described in any of the above embodiments. The waterproof member 120 is compressed by the hard plastic protective member 210 to improve the protection.

[0044] The serial port protection structure 100 includes a protective cover 110 and a waterproof component 120; a fastening part 111 for fastening with the industrial equipment housing is provided along the edge of the protective cover 110, and the protective cover 110 has a slot 112; the waterproof component 120 fits into the slot 112 to close the slot 112; wherein, the protective cover 110 is made of a rigid material, and the waterproof component 120 is made of a flexible material.

[0045] Specifically, the industrial equipment can be a frequency converter, control cabinet, or other device with a communication interface 200. The industrial equipment can include any interactive device that needs to communicate with external devices, such as an industrial equipment keyboard 1000. The industrial equipment keyboard 1000 can include a communication interface 200 and a serial port protection structure 100. The serial port protection structure 100 covers the communication interface 200 to seal the communication interface 200, thereby improving the overall protection performance of the industrial equipment.

[0046] A rigid protective element 210 can be installed around the communication interface 200. This rigid protective element 210 is designed to work in conjunction with the waterproof element 120 to enhance protective performance. The rigid protective element 210 is arranged in a ring around the communication interface 200, and its shape and size perfectly match the gaps around the interface. This precisely limits the sealing range to critical areas of the interface prone to dust / water ingress, achieving precise protection. The rigid structure provides sufficient structural strength for the rigid protective element 210, allowing it to maintain its shape and prevent bending or deformation under conditions of vibration, minor impacts, or frequent opening and closing of the serial port cover that industrial equipment may encounter.

[0047] The serial port protection structure 100 may include a protective cover 110 and a waterproof component 120. The protective cover 110 and the waterproof component 120 are made of different materials. The protective cover 110 is made of rigid material, while the waterproof component 120 is made of flexible material. For example, the protective cover 110 may be made of hard plastic, and the waterproof component 120 may be made of foam material and attached and fixed to the groove 112 of the protective cover 110 by adhesive; or it may be made of soft plastic material and connected to the protective cover 110 by two-color plastic molding.

[0048] The protective cover 110 may have a fastening part 111 and a groove 112. A waterproof component 120 is attached to the groove 112, and the groove 112 can be sealed by the waterproof component 120. The protective cover 110 also has multiple fastening parts 111 for connecting with the housing of industrial equipment to fix the protective cover 110 to the industrial equipment. When the protective cover 110 is fixed by the fastening parts 111, the rigid rubber protective component 210 exerts concentrated pressure on the waterproof component 120. Because the ribs are raised rigid structures, the pressure is concentrated on the contact line between the rigid rubber protective component 210 and the waterproof component 120, rather than being dispersed over a wide surface. This concentrated compression causes reliable deformation of the waterproof component 120, filling the tiny gaps between the rigid rubber protective component 210 and the protective cover 110, ultimately forming a seamless sealing barrier that effectively prevents dust, moisture, and other impurities from entering the interface, solving the defect of insufficient pressure in existing narrow-edge space structures that leads to water ingress.

[0049] As a further embodiment, the industrial equipment keyboard 1000 has a mounting hole 220 on its housing opposite the fastening part 111.

[0050] The industrial equipment keyboard 1000 may have mounting holes 220 and limiting grooves 230 on its housing. The mounting holes 220 are used to engage with the fastening parts 111 to achieve fastening, and the limiting grooves 230 are used to engage with the limiting parts 116 of the serial port protection structure 100 to achieve limiting and control of the rotation angle. The number of mounting holes 220 is the same as the number of fastening parts 111, and the positions of the mounting holes 220 and the fastening parts 111 correspond one-to-one. During installation, the fastening parts 111 are inserted into the mounting holes 220 to achieve fastening between the protective cover 110 and the housing of the industrial equipment keyboard 1000, thereby achieving compression and interference between the hard rubber protective part 210 and the waterproof part 120 to form a high protection effect for the communication interface 200.

[0051] The serial port protection structure and industrial equipment disclosed in this utility model have a fastening part on the edge of the protective cover for fastening with the housing of the industrial equipment. The protective cover also has a groove, and a waterproof component is attached to the groove. The waterproof component can be squeezed by the hard rubber protective component, and then the protective cover is fastened to the housing of the industrial equipment to provide the pressure for deformation. This can provide the pressure required to meet the protection performance and meet the protection requirements of the communication interface in the narrow edge space structure.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
