Similarly, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Exceptions to this definition will only occur when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.
[0026] It should be understood that the terms "top", "bottom", "upper", "lower", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application.
[0027] For ease of description, the following embodiments are all illustrated using an orthogonal space formed by a horizontal plane and a vertical direction as an example. This premise should not be construed as a limitation of this application.
[0028] Please refer to Figures 1 to 4 The support device of this application includes a bracket body 1 and a fixing base 2.
[0029] In the specific implementation process, the fixing seat 2 is configured on the bracket body 1, wherein the bracket body 1 is recessed to form an assembly slide 11, the fixing seat 2 includes a first mounting surface 3 and a second mounting surface 4, the first mounting surface 3 and the second mounting surface 4 maintain a set tilt angle, and a boss 21 is provided on the side of the first mounting surface 3 or the second mounting surface 4 facing the bracket body 1, the boss 21 is matched in the assembly slide 11.
[0030] Preferably, a first limiting hole 121 is recessed on the bracket body 1, and a second limiting hole 122 is recessed on the fixing seat 2. The first limiting hole 121 and the second limiting hole 122 are connected and communicate with each other.
[0031] The support device is detachably connected to the external environment through the fixed base 2. Specifically, the first mounting surface 3 and the second mounting surface 4 of the fixed base 2 maintain a set tilt angle, that is, the fixed base 2 can flexibly adapt to various installation scenarios (such as horizontal walls, inclined surfaces or under eaves) through the first mounting surface 3 and / or the second mounting surface 4, thereby ensuring the accurate installation of the video monitoring terminal mounted on the bracket body 1 at different angles, effectively expanding the field of view of video monitoring, reducing blind spots, and improving the adaptability of actual application scenarios.
[0032] Furthermore, after the boss 21 on the first mounting surface 3 or the second mounting surface 4 is embedded into the assembly slide 11 on the bracket body 1, a stable mechanical connection structure is formed. This not only improves the connection between the fixed seat 2 and the bracket body 1, but also effectively prevents problems such as loosening or slippage during use. Moreover, the fitting method of the boss 21 and the assembly slide 11 makes the installation and disassembly process of the bracket body 1 simpler, reduces the complexity of user operation, and reduces the time cost of construction and installation.
[0033] In one application scenario, the mounting base 2 can be pre-fixed to the external environment. Specifically, depending on the actual application site, the side of the first mounting surface 3 and / or the second mounting surface 4 that is away from the bracket body 1 can be fixed to the external environment. Then, the bracket body 1 is assembled on the mounting base 2, thereby achieving the purpose of flexible installation. This makes the subsequent maintenance, angle adjustment or replacement of parts of the video surveillance terminal more convenient, and greatly improves the efficiency of equipment use and maintenance.
[0034] Furthermore, the first limiting hole 121 and the second limiting hole 122 are connected and communicate with each other to limit and lock the bracket body 1 and the fixed seat 2. For example, the bracket body 1 and the fixed seat 2 can be fixed by using a limiting pin or bolt through the first limiting hole 121 and the second limiting hole 122, thereby ensuring the stable connection between the bracket body 1 and the fixed seat 2 and enhancing the vibration resistance and durability of the support device.
[0035] Optionally, the first limiting hole 121 is arranged on the side wall of the bracket body 1, and the second limiting hole 122 is recessed on the boss 21. That is, the hole-like structure of the first limiting hole 121 and the second limiting hole 122 can be regarded in space as passing through the side wall of the bracket body 1 through the assembly slide 11 and acting on the boss 21. Based on this through-hole arrangement of the first limiting hole 121 and the second limiting hole 122, the boss 21 can be prevented from shifting in the assembly slide 11, providing multiple fixing guarantees for the cooperation between the boss 21 and the assembly slide 11, so that the bracket body 1 can remain stable when subjected to external forces (such as wind pressure, vibration, etc.).
[0036] On the other hand, through the recessed design of the mounting slide 11, the bracket body 1 can install different specifications of fixing seats 2 according to different equipment or environmental requirements, thereby improving the compatibility and adaptability of the bracket body 1 to various video surveillance terminal equipment. In other words, this modular design helps to realize the mass production of support devices and the universality of parts, reducing the cost of product manufacturing and maintenance.
[0037] It is understood that the bracket body 1 in this embodiment can be used to mount a video surveillance terminal, which may include smart terminals such as cameras, monitors, video recorders, and infrared imagers.
[0038] Optionally, the boss 21 matches the outer wall contour of the mounting slide 11, so that the two can fit tightly together, reducing the shaking and gaps at the connection, thereby improving the overall stability of the bracket body 1 and the fixed seat 2 after installation. The tight matching design can reduce the possibility of external dust, rainwater, etc. entering the mounting slide 11 through the gaps, and extend the service life of the support device.
[0039] In one embodiment, a plurality of reinforcing ribs 5 are integrally connected to the side of the first mounting surface 3 and the second mounting surface 4 opposite to the bracket body 1. The reinforcing ribs 5 are staggered on the first mounting surface 3 and the second mounting surface 4. The design of the reinforcing ribs 5 can effectively improve the overall mechanical strength of the first mounting surface 3 and the second mounting surface 4, enhance their ability to withstand external loads and pressures, and improve the fatigue resistance of the first mounting surface 3 and the second mounting surface 4 when subjected to vibration or impact. Especially in the case of long-term use, it can effectively avoid loosening or fatigue damage. The staggered arrangement can further optimize the force distribution, so that the reinforcing ribs 5 can evenly distribute the pressure on the fixed seat 2, reduce local stress concentration, and prevent deformation or breakage. At the same time, the reinforcing ribs 5 are integrally connected with the first mounting surface 3 and the second mounting surface 4 to form an integral force-bearing structure, reducing the performance degradation caused by loosening or wear between components and preventing the fixed seat 2 from being damaged due to overload.
[0040] Optionally, the reinforcing ribs 5 are arranged in a "well" shape or a "field" shape on the first mounting surface 3 and the second mounting surface 4.
[0041] Furthermore, a plurality of mounting holes 22 are arranged on the first mounting surface 3 and the second mounting surface 4. The mounting holes 22 are arranged around the reinforcing rib 5, thereby allowing the first mounting surface 3 and / or the second mounting surface 4 to be fixedly connected to the external environment through the mounting holes 22. The design of the mounting holes 22 surrounding the reinforcing rib 5 ensures the rational distribution of the mounting holes 22 and avoids structural interference between the mounting holes 22 and the reinforcing rib 5. At the same time, the high-strength design of the reinforcing rib 5 provides a good support effect, preventing hole deformation or cracking under external tension or pressure. That is, the mounting holes 22 are arranged around the reinforcing rib 5, which makes the stress on the hole position more uniform and avoids stress concentration, thereby improving the stability of the equipment in long-term operation. Thus, the plurality of mounting holes 22 realize multi-point fixation of the first mounting surface 3 and / or the second mounting surface 4 to the external environment, further improving the reliability and load-bearing capacity of the support device, especially in the installation of large-sized or heavy equipment on vertical walls, sloping eaves or horizontal support rods.
[0042] In one embodiment, a docking seat 6 is integrally connected to one end of the bracket body 1 near the fixed seat 2. An assembly slide 11 is formed on the docking seat 6, and the fixed seat 2 is attached to the docking seat 6. Through the integral design of the docking seat 6, the problems of loosening or insufficient connection strength caused by using screws or welding can be avoided, thereby improving the overall structural robustness and vibration resistance of the bracket body 1. The fixed seat 2 is in close contact with the docking seat 6 through the attachment method, and the assembly slide 11 provides precise installation guidance for the fixed seat 2, which simplifies the installation process. Moreover, when it is necessary to replace or repair the video surveillance terminal, it is only necessary to separate the fixed seat 2 and the docking seat 6, thereby improving the flexibility of the detachable connection.
[0043] Optionally, the docking seat 6 is located on the outer wall of the end of the bracket body 1, which can avoid structural interference with the equipment inside the bracket body 1 (such as circuit boards, wiring terminals, etc.) and does not occupy the limited space inside the bracket body 1, so that the bracket body 1 can accommodate more functional components (such as camera modules, power supply modules, communication modules, etc.) to improve the utilization rate of the internal space of the equipment.
[0044] Furthermore, an alignment block 23 is protruding from the side of the first mounting surface 3 or the second mounting surface 4 facing the docking seat 6, and an alignment groove 61 is recessed on the docking seat 6 at the position corresponding to the alignment block 23. The alignment block 23 is matched in the alignment groove 61. Based on the setting of the alignment block 23 and the alignment groove 61, it is ensured that the first mounting surface 3 or the second mounting surface 4 can accurately align the position of the docking seat 6, avoiding assembly problems caused by misalignment or offset. The alignment block 23 is embedded in the alignment groove 61 to form a stable connection point, which can effectively prevent loosening or displacement between the fixed seat 2 and the docking seat 6 during use due to vibration, impact or long-term use. That is, during the assembly process of the fixed seat 2 and the bracket body 1, the matching of the alignment block 23 and the alignment groove 61 provides a clear guiding function, reduces the adjustment and alignment time, thereby speeding up the assembly efficiency and improving the connection stability.
[0045] Furthermore, the alignment block 23 forms a concealed connection after being embedded in the alignment slot 61, which can optimize the overall appearance of the support device, making the equipment look simpler, more beautiful and professional. At the same time, it reduces the exposed area of external connection components, thereby reducing the interference of the external environment on the connection parts and improving the overall user experience of the equipment.
[0046] In one embodiment, the bracket body 1 is provided with a solar panel 7, which covers the upper end face of the bracket body 1 and is electrically connected to the battery compartment of the video surveillance terminal inside the bracket body 1. Through the design of the solar panel 7, the dependence on traditional power resources can be reduced, the need for mains power or external battery replacement can be reduced, and the electricity cost and maintenance cost during operation can be significantly reduced. That is, the solar panel 7 can continuously charge the battery compartment, improve the endurance of the video surveillance terminal in the event of power failure or external power interruption, and ensure that the equipment can operate continuously and stably for a long time.
[0047] Optionally, an auxiliary housing 13 is connected to the upper end of the support body 1. The auxiliary housing 13 is provided with a mounting groove 14 that maintains a gap with the support body 1. The solar panel 7 is connected to the mounting groove 14. Through the design of the auxiliary housing 13 and the mounting groove 14, the solar panel 7 can be stably installed on the support body 1, avoiding the risk of the solar panel 7 loosening or falling off due to vibration or external impact. The gap between the auxiliary housing 13 and the support body 1 forms a certain heat dissipation space and physical isolation, thereby improving the safety of the support body 1. That is, the auxiliary housing 13 provides additional protection for the support body 1, which helps to prevent electrical short circuit problems that may be caused by structural conductivity or external interference.
[0048] Furthermore, through the arrangement of the auxiliary housing 13 and the mounting groove 14, the solar panel 7 becomes an independent module, which can be flexibly combined or replaced with other components, thereby realizing the customized design of the support device.
[0049] Continue to combine Figure 4 and 5 The lower end of the bracket body 1 is connected to a functional housing 15. The inner wall of the functional housing 15 is provided with several guide grooves 16, and corresponding drainage holes 17 penetrating the bracket body 1 are opened in the guide grooves 16. By setting the guide grooves 16 on the inner wall of the functional housing 15, water vapor condensation can be effectively guided, helping water to flow quickly to the drainage holes 17, reducing the water retention time, thereby reducing potential damage to the equipment. That is, the setting of the drainage holes 17 can allow the water in the guide grooves 16 to be smoothly discharged from the bracket body 1, avoiding water accumulation inside the structure and preventing water from penetrating into the internal components. The protection of electronic equipment is particularly important. Timely drainage can ensure the dryness of the bracket body 1 and internal components, reduce the risk of corrosion and electrical failure, protect the equipment from rain, dew or moisture, reduce metal corrosion caused by moisture, especially in coastal or humid environments, enhance the corrosion resistance of the equipment, and extend the service life of the equipment.
[0050] Understandably, the functional housing 15 is provided with an audio port 8 and a camera port 9, which are spaced apart to facilitate the mounting of the bracket body 1 with respect to the audio and camera. The audio port 8 and the camera port 9 are located on the side of the functional housing 15 away from the solar panel 7 to avoid environmental interference and rainwater erosion.
[0051] In one embodiment, a set tilt angle is maintained between the first mounting surface 3 and the second mounting surface 4. The set tilt angle is adjustable. Specifically, a pivot or hinge can be provided between the first mounting surface 3 and the second mounting surface 4, and the pivot or hinge connects the first mounting surface 3 and the second mounting surface 4 respectively, so as to adjust the set tilt angle in real time according to different installation requirements and usage scenarios, thereby improving the applicability and space utilization of the equipment.
[0052] In one embodiment, a set tilt angle is maintained between the first mounting surface 3 and the second mounting surface 4. The set tilt angle includes 60°, 90° or 120°, that is, the first mounting surface 3 and the second mounting surface 4 maintain a design angle of 60°, 90° or 120° to meet different installation requirements and usage scenarios. Users can choose the most suitable angle according to the actual situation, such as different walls, bracket heights or other installation constraints, so as to flexibly adjust the installation direction and viewing angle of the support device, thereby improving the applicability and space utilization of the equipment.
[0053] Preferably, the tilt angle is set to 90°, that is, the first mounting surface 3 and the second mounting surface 4 are designed to be perpendicular to each other. This allows the support device to be installed vertically or horizontally, or both vertically and horizontally, with respect to the external environment such as the target wall. This multi-functional installation method enables the support device to adapt to various environmental requirements and improves the versatility and adaptability of the product.
[0054] This application also discloses an electronic device, including a support device as described in any of the above embodiments.
