[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] It should be noted that the building intercom host 10 is usually wall-mounted and directly fixed to the wall by the wall bracket 20; while the barrier gate 40 is mostly column-mounted and vertically fixed to the ground or entrance fence by the support column.

[0021] See Figures 1-12 This invention illustrates a preferred embodiment of a universal rainproof and sunshade for a building intercom main unit 10 or a barrier gate 40, comprising: Cover body 1, used to cover the exterior of building intercom main unit 10 or barrier gate 40, and the back of cover body 1 has mounting opening 14; and A connecting back plate 2 is located on the back of the cover body 1 and covers the mounting opening 14. The connecting back plate 2 has a first clearance hole 21 and a connecting hole 22. The first clearance hole 21 passes through the connecting back plate 2 from both the front and back. The first clearance hole 21 is used for the connecting part 201 of the wall bracket 20 of the building intercom host 10 to pass through, so that the connecting part 201 of the wall bracket 20 can be normally connected to the outlet box 30. Alternatively, the first clearance hole 21 is used for the connecting end 401 of the column of the barrier gate 40 to pass through, so that the barrier gate 40 can be normally connected to the connecting end 401 of the column. The connecting hole 22 passes through the connecting back plate 2 from both the front and back and is used for fasteners (not shown in the figure) to pass through, so that the connecting back plate 2 can be connected to the barrier gate 40.

[0022] This utility model discloses a universal rainproof sunshade that is compatible with building intercom main unit 10 or barrier gate 40 via a connecting back plate 2. When applying this universal rainproof sunshade to the building intercom main unit 10, the connecting back plate 2 is placed between the cable outlet box 30 and the wall mount bracket 20, which are compatible with the building intercom main unit 10. The clamping action of the cable outlet box 30 and the wall mount bracket 20 secures the connecting back plate 2, thus achieving a fixed installation of the universal rainproof sunshade. The first clearance hole 21 allows the connecting part 201, which connects the wall mount bracket 20 and the cable outlet box 30, to pass through, ensuring a proper connection between the connecting part 201 and the cable outlet box 30. Finally, the building intercom main unit 10 is installed on the wall mount bracket. On step 20, the overall assembly is completed. When applying this universal rainproof sunshade to the barrier gate 40, the connecting end 401 of the column passes through the first clearance hole 21 from the back of the connecting back plate 2. Then, the barrier gate 40 is installed on the connecting end 401 of the column. Finally, the connecting hole 22 of the connecting back plate 2 and the connecting hole of the barrier gate 40 are locked together with fasteners to achieve fixation. This universal rainproof sunshade can be adapted to both the building intercom host 10 and the barrier gate 40. It has strong versatility and a wider range of applications, reduces the need for special accessories, facilitates centralized production, and thus reduces manufacturing costs. At the same time, the universal rainproof sunshade adopts a standardized structural design, which can simplify the installation process and improve installation efficiency.

[0023] In one embodiment, the connecting part 201 is specifically connected to the outlet box 30 by a fastening screw 50, and the fastener is specifically a screw, but may also be a bolt, rivet or other fastening structure.

[0024] In one embodiment, the cover body 1 and the connecting back plate 2 are separately configured. The separate design allows different materials or processes to be used for the cover body 1 and the connecting back plate 2. For example, the cover body 1 is made of lightweight plastic to reduce the overall weight, and the connecting back plate 2 is made of metal to enhance the structural strength, thereby optimizing cost and performance while ensuring functionality.

[0025] In one embodiment, the cover body 1 and the connecting back plate 2 are connected together by welding. This structure enhances the mechanical strength and stability of the overall structure through an integrated welding process, avoiding the loosening or gap problems that may exist in traditional split connections. At the same time, the welding connection can effectively improve the sealing performance, preventing moisture, dust or other external pollutants from entering the building intercom host 10 or the barrier gate 40. In addition, the welding process simplifies the assembly process, reduces additional connecting parts (such as screws, clips, etc.), reduces production costs and assembly complexity, and the overall structure after welding has higher rigidity and deformation resistance, which can better protect the building intercom host 10 or the barrier gate 40 from external impacts or compression, thereby extending the service life of the building intercom host 10 or the barrier gate 40. From a manufacturing perspective, the welding connection facilitates automated production, improves processing efficiency, and ensures the consistency of the universal rainproof sunshade. At the same time, the integrated design of the welding structure can also optimize the appearance, avoid exposed connecting parts, and improve the aesthetics and integrity of the universal rainproof sunshade.

[0026] Of course, in other embodiments, the cover body 1 and the connecting back plate 2 can also be connected together by screws, buckles or other connectors. In this case, a sealing structure can be added at the connection between the cover body 1 and the connecting back plate 2 to seal the gap between the two and improve the rainproof effect.

[0027] See Figures 1-4 In one embodiment, the cover body 1 includes: The top plate 11 has a first extension plate 111 at its rear end, and the first extension plate 111 extends downward. A first side plate 12 is located on the first side of the top plate 11 in the left-right direction. The upper end of the first side plate 12 is connected to the top plate 11. A second extension plate 121 is provided at the rear end of the first side plate 12, extending towards the second side of the top plate 11 in the left-right direction. The second side plate 13 is located on the second side of the top plate 11 in the left and right direction. The upper end of the second side plate 13 is connected to the top plate 11. The rear end of the second side plate 13 is provided with a third extension plate 131, which extends toward the first side plate 12. The third extension plate 131, the second extension plate 121, and the first extension plate 111 form an installation opening 14, and the connecting back plate 2 connects the third extension plate 131, the second extension plate 121, and the first extension plate 111. Since the cover body 1 includes a top plate 11, a first side plate 12, and a second side plate 13, the rear end of the top plate 11 has a downward-extending first extension plate 111. The first side plate 12 is located on the first side of the top plate 11 in the left-right direction and its upper end is connected to the top plate 11; its rear end has a second extension plate 121 extending towards the second side. The second side plate 13 is located on the second side of the top plate 11 in the left-right direction and its upper end is connected to the top plate 11; its rear end has a third extension plate 131 extending towards the first side plate 12. The installation opening 14 is formed by the cooperation of the third extension plate 131, the second extension plate 121, and the first extension plate 111, and the connecting back plate 2 connects the three. This structure, through multi-directional extension... The extension design enables precise positioning and stable forming of the mounting port 14. The coordinated cooperation of each extension plate not only enhances the overall structural strength of the cover body 1, but also optimizes the assembly accuracy and connection reliability of the connecting back plate 2. The multi-directional extension layout of the extension plates makes the mounting port 14 form a three-dimensional surrounding structure, effectively improving the torsional and deformation resistance of the connecting part 201. In addition, while ensuring the dimensional accuracy of the mounting port 14, this extension structure can adapt to connecting back plates 2 of different thicknesses, improving the versatility and assembly compatibility of the structure. Moreover, the edge of the mounting port 14 formed by bending is naturally transitioned, avoiding sharp edges, which improves both safety performance and appearance.

[0028] In one embodiment, the top plate 11 is integrally formed with the first extension plate 111; The first side plate 12 and the second extension plate 121 are integrally formed; The second side plate 13 and the third extension plate 131 are integrally formed. This structure significantly improves the structural strength and overall stability of the various plates of the cover body 1 through the integral forming process, avoiding the loosening of connections or assembly errors that may occur with traditional separate connection methods. At the same time, the integral forming design reduces the number of assembly steps and connecting parts 201, effectively reducing production costs and improving production efficiency. The integral forming of each extension plate and its corresponding plate ensures the accuracy and consistency of bending angles, thereby optimizing the dimensional accuracy of the mounting port 14 and the assembly reliability of the connecting back plate 2. Furthermore, the integral forming structure eliminates stress concentration or appearance defects that may be caused by welding or riveting, which not only enhances the durability of this general-purpose rainproof sunshade but also improves its appearance quality. In addition, the integral forming process simplifies the production process, making it easier to achieve standardized and large-scale production. Meanwhile, the continuity and integrity of the overall structure also improves the sealing performance and deformation resistance of the cover body 1, enabling it to better adapt to the long-term use requirements in complex environments.

[0029] See Figures 1-4In one embodiment, the universal rainproof and sunshade for the building intercom main unit 10 or the barrier gate 40 further includes: The first sealing element 3 is sandwiched between the front of the connecting back plate 2 and the wall bracket 20 of the building intercom host 10. The first sealing element 3 is arranged around the first clearance hole 21 and covers the connecting hole 22. The second sealing element 4 is sandwiched between the back of the connecting back plate 2 and the wall surface. The second sealing element 4 surrounds the first clearance hole 21 and covers the connecting hole 22. The arrangement of the first sealing element 3 and the second sealing element 4 forms a double sealing structure. This double sealing structure effectively blocks the intrusion path of external pollutants such as rainwater and dust from the connecting hole 22 and the first clearance hole 21 through a front and rear bidirectional sealing design, significantly improving the protection level and service life of this universal rainproof sunshade. Furthermore, the synergistic effect of the first sealing element 3 and the second sealing element 4 forms a three-dimensional sealing barrier, not only preventing rainwater from seeping into the building intercom host 10 along the wall-mounted bracket 20, but also blocking the reverse infiltration of moisture from the back wall through the connecting hole 22, achieving comprehensive sealing. The dual-seal structure provides environmental isolation protection; at the same time, the design of covering the connection hole 22 avoids the defect of easy water leakage at the bolt hole in the traditional sealing method. The arrangement of the first seal 3 and the second seal 4 around the first clearance hole 21 ensures the normal use of the building intercom host 10 interface without affecting the heat dissipation and ventilation requirements. In addition, the dual-seal structure is easy and reliable to install. It can achieve waterproof and dustproof effect without additional modification of the existing equipment structure, which greatly reduces maintenance costs and improves environmental adaptability. It is especially suitable for long-term stable operation under harsh outdoor conditions.

[0030] See Figures 10-12 In one embodiment, the universal rainproof and sunshade for the building intercom main unit 10 or the barrier gate 40 further includes: The third sealing element 5 is sandwiched between the front of the connecting back plate 2 and the back of the barrier gate 40. The third sealing element 5 is arranged around the first clearance hole 21. The arrangement of the third sealing element 5 effectively blocks the intrusion path of external pollutants such as rainwater and dust from the first clearance hole 21, significantly improving the protection level and service life of the general-purpose rainproof sunshade.

[0031] See Figure 12In one embodiment, the third seal 5 has a second clearance hole 51, which is disposed around the connection hole 22. This structure achieves synergistic optimization of sealing protection and connection between the barrier gate 40 through the precise alignment design of the second clearance hole 51. It maintains the comprehensive sealing effect of the third seal 5 on the mating surface between the connecting back plate 2 and the barrier gate 40, while ensuring unobstructed installation, disassembly, and maintenance of fasteners such as connecting bolts through the structure of the second clearance hole 51. The layout of the second clearance hole 51 around the connecting hole 22 forms an annular sealing band, establishing a continuous and uniform sealing pressure distribution around the fasteners, effectively preventing rainwater from seeping into the interior of the barrier gate 40 along the gaps between the fasteners. At the same time, this design avoids the installation errors and sealing failure risks caused by the need for on-site drilling of traditional seals, significantly improving installation accuracy and sealing reliability. In addition, the integrated structure of the second clearance hole 51 allows the third seal 5 to adapt to the arrangement requirements of connecting holes 22 of different specifications. The standardized pre-formed design simplifies the installation process, reduces the difficulty of manual operation, and ensures the consistency of sealing performance during mass production, extending the service life of the barrier gate 40 under harsh outdoor conditions.

[0032] In one embodiment, the first seal 3, the second seal 4, and the third seal 5 are all structures made of waterproof foam material. Waterproof foam combines elastic deformation capability with durable waterproof properties, enabling it to form a highly reliable compression seal between the connecting backplate 2 and the equipment (including the intercom host 10 or the barrier gate 40) and the wall surface, maintaining stable sealing performance even under long-term pressure. Secondly, this material has excellent weather resistance and anti-aging properties, adapting to temperature changes and ultraviolet radiation in outdoor environments, ensuring that the seals do not harden, crack, or fail during long-term use. Furthermore, the softness of waterproof foam allows it to adapt to the microscopic unevenness of different installation surfaces, filling tiny gaps to form a continuous sealing interface. At the same time, its moderate compression resilience ensures a good sealing effect during installation and fastening while avoiding material fatigue caused by excessive compression. In addition, using a uniform material to manufacture the seals simplifies the production process and material management, ensures the consistency of the performance of each sealing interface, and the waterproof foam material is easy to process and mold, allowing for the precise manufacture of seals with complex structures such as the second clearance hole 51, improving product yield and reducing production costs.

[0033] Of course, in other embodiments, the first seal 3, the second seal 4, and the third seal 5 can all be structures made of rubber.

[0034] See 1. Figure 3 , Figure 7 as well as Figure 8In one embodiment, the front of the connecting back plate 2 is provided with an anti-tamper protrusion 23. The anti-tamper protrusion 23 is used to cooperate with the anti-tamper sensor 6 on the building intercom host 10 or the anti-tamper sensor 6 on the barrier gate 40. The anti-tamper sensor 6 on the building intercom host 10 is electrically connected to the circuit board on the building intercom host 10, and the anti-tamper sensor 6 on the barrier gate 40 is electrically connected to the circuit board on the barrier gate 40. Thus, the coordinated cooperation between the anti-tamper protrusion 23 and the anti-tamper sensor 6 can immediately trigger an alarm signal when unauthorized disassembly occurs, effectively deterring and preventing the general-purpose rainproof sunshade from being maliciously damaged or stolen. The placement of the anti-tamper protrusion 23 is precisely calculated to ensure stable contact or proximity with the anti-tamper sensor 6 under normal installation conditions, while generating sufficient displacement during unauthorized disassembly to trigger an alarm signal. Its structural design does not affect the normal installation and maintenance process of the general-purpose rainproof sunshade, and can respond quickly to any abnormal disassembly action. Furthermore, the integrated design of the anti-tamper protrusion 23 and the connecting back plate 2 enhances the structural strength and avoids the assembly complexity and cost increase caused by additional anti-tamper parts. At the same time, this solution is compatible with the technical specifications of existing mainstream anti-tamper sensors 6, and can achieve the anti-tamper function immediately without structural modification of the building intercom host 10 or the barrier gate 40, which greatly improves the safety and market adaptability of the equipment. The standardized design of the anti-tamper protrusion 23 also facilitates mass production and quality control, ensuring that each universal rainproof sunshade has consistent and reliable anti-tamper protection performance.

[0035] It should be noted that after the equipment is fully assembled (i.e., after the universal rainproof and sunshade is installed on the building intercom host 10 or the barrier gate 40), authorized personnel must access the password verification process through the human-machine interface of the building intercom host 10 or the barrier gate 40. Only after successful verification can they access the system settings menu and enable the "anti-tamper function" module. This password access is strictly limited to the equipment management personnel. When equipment maintenance is required, maintenance personnel must follow the standard operating procedure and first disable the anti-tamper function through password verification before performing disassembly work to ensure the safety of the equipment. All disassembly operations are under system monitoring. The system employs a dual electromechanical detection mechanism. When unauthorized disassembly is detected, causing the general-purpose rainproof sunshade to separate from the building intercom host 10 or the barrier gate 40, the anti-tamper sensor 6 installed on the general-purpose rainproof sunshade will immediately trigger a signal change. This signal change will simultaneously activate two levels of alarm response: the local alarm unit will immediately activate a high-decibel audible and visual alarm device, and at the same time, it will send the equipment abnormality status code and location information to the remote monitoring center (including property management platform, security system, etc.) through the IoT communication module. This anti-tamper system achieves comprehensive coverage of equipment security protection through the coordinated work of software access control and hardware triggering devices.
