Description

Technical Field

[0001] This utility model relates to the field of redundant power supply technology, specifically to a redundant hot backup power supply with better assembly performance. Background Technology

[0002] For systems requiring long-term uninterrupted operation and high reliability, such as base station communication equipment, monitoring equipment, and servers, a highly reliable power supply is often necessary. Redundant power supply design is a crucial component, playing a vital role in high-availability systems. Redundant power supplies typically employ two or more power circuit modules. When one power circuit module fails, the remaining functional modules can continue to operate stably to maintain the system's power requirements, thereby meeting the reliability requirements of the power system.

[0003] A redundant hot-standby power supply refers to a power supply composed of multiple units that operate simultaneously, but only one unit supplies power to the device while the others remain idle. In the event of a main power supply failure, the backup power supply can immediately take over with minimal output voltage fluctuations. Compared to other types of redundant power supplies, redundant hot-standby power supplies offer higher reliability and stability.

[0004] However, in existing technologies, redundant hot backup power supplies are usually separate box structures, which are not conducive to fixed positions, making installation and maintenance difficult. They also occupy a lot of space, which is not conducive to compact settings, reducing the convenience of assembly and use, and easily affecting the overall system layout. In addition, traditional redundant hot backup power supplies also have defects in heat dissipation and protection, which can easily lead to a decline in power supply performance and even cause safety accidents during use.

The top plate is a right-angled triangle, and the two lower side plates are fixed to the lower sides of the two right-angled sides of the top plate. The top plate and the two lower side plates are perpendicular to each other.

[0008] The redundant power supply host and the backup power supply are respectively mounted on the inner side of two lower side plates, and the redundant power supply host and the backup power supply are electrically connected.

[0009] The top plate and the lower side plate are formed with magnetic connectors, which allow the redundant hot backup power supply to be attracted and fixed to the corner of the iron box-shaped equipment through the magnetic connectors on the combined protective frame.

[0011] As a further limitation, the top plate and the lower side plate in the combined guard frame are fixedly connected by one or a combination of welding connection, connector connection, and bending forming.

[0012] As a further limitation, the lower surface of the top plate and the outer surfaces of the redundant power supply main unit and the backup power supply are lined with soft material padding as a cushioning and protective lining.

[0013] As a further limitation, the lower side plate has an outer contour shape larger than that of the corresponding redundant power supply host / backup power supply; the magnetic connector is formed at the outer edge of the lower side plate and includes a connecting rod and a magnetic connector body, wherein the connecting rod is perpendicular to the plane of the lower side plate, the base of the connecting rod is fixedly connected to the lower side plate, and the outer end is fixedly connected to the magnetic connector body.

[0014] As a further limitation, a gap is reserved between the two lower side panels to serve as a heat dissipation channel.

[0015] As a further limitation, the lower side plate has heat dissipation windows formed on the plate surface at the corresponding redundant power supply host assembly position.

[0016] As a further limitation, the redundant power supply host's plug-in holes and operation panel are formed on the side.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] See Figure 1 A preferred embodiment of the redundant hot backup power supply, in this embodiment, the redundant hot backup power supply includes a redundant power supply host 8, a backup power supply 5, and a combined protective frame.

[0025] Among them, the redundant power supply host 8 is the host component that realizes the redundant hot backup power supply function. It can be obtained by purchasing from the market or assembling with self-purchased components. The redundant power supply host 8 is encapsulated in a flat shell structure. Cooling fans 16 are formed on the inner flat surface and the front and rear sides of the shell to improve the heat dissipation performance of the redundant power supply host 8. In addition, plug-in buckles and connecting contacts are also formed on the front side of the shell of the redundant power supply host 8.

[0026] The backup power supply 5 is a rechargeable lithium battery used to provide power support when the redundant power supply host 8 fails. The redundant power supply host 8 also has a built-in power management chip, which can monitor its own operating status in real time and realize the redundant hot backup power supply function. In addition, it can also monitor the power status of the backup power supply 5 in real time and automatically charge it when the power is too low to avoid power outage caused by power depletion.

[0027] The backup power supply 5 is also encapsulated in a flat housing structure, and the inner flat surface of the flat housing structure is formed with a plug-in portion. The front side of the backup power supply 5 is also formed with a plug socket that matches the plug-in buckle and another contact that matches the communication contact on the redundant power supply host 8.

[0028] The combined protective frame is a three-panel structure, including a top plate 11, a first lower side plate 1, and a second lower side plate 12. In this embodiment, the combined protective frame is formed by cutting and bending a single piece of cold-rolled steel plate, and then coating it with an antistatic shielding coating after forming.

[0029] In the formed combined protective frame, the top plate 11 is an isosceles right triangle, with a cut edge left at the right-angle vertex of the isosceles right triangle as a through heat dissipation channel 7; the first lower side plate 1 and the second lower side plate 12 are respectively obtained by bending at the two right-angled sides of the top plate 11. In different embodiments, the first lower side plate 1 and the second lower side plate 12 can be designed with different shapes and sizes according to actual needs to adapt to the assembly requirements of different models of redundant power supply host 8 and backup power supply 5, but it must be ensured that the first lower side plate 1 and the second lower side plate 12 are perpendicular to the plane of the top plate 11.

[0030] On the inner sides of the first lower side plate 1 and the second lower side plate 12, mounting structures or assembly structures matching the redundant power supply host 8 and the backup power supply 5 are respectively reserved. The inner side of the second lower side plate 12 is formed with a threaded mounting seat, through which the redundant power supply host 8 can be mounted sideways onto the second lower side plate 12, as shown in the figure. The inner side of the first lower side plate 1 is pre-assembled with a plug-in socket 4, which matches the insertion part on the backup power supply 5 and is calibrated so that after the backup power supply 5 is inserted into the plug-in socket 4, it can connect and communicate with the plug-in buckle and contacts on the redundant power supply host 8.

[0031] In this embodiment, magnetic connectors are provided on the inner sides of the top plate 11, the first lower side plate 1, and the second lower side plate 12. The magnetic connector on the top plate 11 is a magnetic connector body II 13, located at the two base corners of the right-angled triangle structure of the top plate 11. The magnetic connectors on the first lower side plate 1 and the second lower side plate 12 are located on the outer sides of the structural outlines of the corresponding backup power supply 5 and redundant power supply host 8, and include a connecting rod 2 and a magnetic connector body 3. The connecting rod 2 is perpendicular to the surface of the corresponding first lower side plate 1 / second lower side plate 12, and is fixedly connected to the surface of the first lower side plate 1 and the second lower side plate 12 at its base, and fixedly connected to the magnetic connector body 3 at its outer end. With this design, the redundant hot backup power supply can be easily attracted and fixed to the corners of the iron box-shaped equipment via the magnetic connectors on the combined frame, enabling rapid installation and disassembly.

[0032] In addition, to improve the heat dissipation performance of the redundant hot backup power supply, heat dissipation windows 9 are formed on the second lower side plate 12. The design of the heat dissipation windows 9 corresponds to the mounting position of the cooling fan 16 on the side of the redundant power supply host 8, and together with the cooling fan 16, it is beneficial to dissipate the heat inside the redundant power supply host 8. At the same time, the heat generated by the redundant power supply host 8 during operation can also be dissipated through the cooling fan 16 on the front and rear sides, through the heat dissipation channel 7 and the outer space, further improving the heat dissipation efficiency.

[0033] For ease of operation, the device panel 10 of the redundant power supply host 8 is located on the side, with corresponding reserved operating space to ensure that operators can still easily operate the host switch 15, the plug hole 17, and the operation panel on the device panel 10 even when assembled, thus improving the ease of use.

[0034] To enhance the protection performance of the redundant hot backup power supply, soft material padding 6 is installed on the lower surface of the top plate 11 and on the sides of the housing of the backup power supply 5 and the redundant power supply host 8 as a buffer protection liner. This design can reduce the damage to the redundant hot backup power supply when subjected to external impacts to a certain extent, improving its durability and safety.

[0035] In this embodiment, the redundant power supply host 8 is first assembled on the second lower side plate 12 of the combined protective frame, and then the backup power supply 5 is assembled on the plug-in socket 4 of the first lower side plate 1. After the redundant power supply host 8 and the backup power supply 5 are assembled, they can be installed on the box-shaped equipment host with iron corner structure. During installation, simply bring the magnetic connector on the combined protective frame close to the corner of the equipment host 14 to be equipped, and the magnetic connector will automatically attract and fix it to the corner of the equipment host 14 to be equipped, realizing the quick fixation of the redundant hot backup power supply. This installation process does not require the use of additional fasteners or tools, greatly simplifying the installation process and improving installation efficiency; when maintenance or replacement of the redundant hot backup power supply is required, the operator only needs to overcome the magnetic force to remove the redundant hot backup power supply from the equipment, again without the need for additional tools, reducing maintenance difficulty and improving maintenance efficiency.

[0036] In addition, to enhance the communication capabilities and scalability of the redundant power supply host 8, it also features a communication expansion interface. This interface, through a matching communication expansion module, enables communication and data exchange with other devices, allowing the redundant hot backup power supply to easily integrate into various complex systems and work collaboratively with different devices. This design significantly enhances the host's compatibility and flexibility, enabling it to meet the needs of various application scenarios.

[0037] It is worth mentioning that the redundant hot backup power supply of this utility model, through its innovative combined protective frame design, not only achieves efficient fixing and installation of the redundant hot backup power supply, but also effectively improves the heat dissipation performance of the redundant hot backup power supply by reserving heat dissipation channels, setting heat dissipation windows and cooling fans, thus avoiding power performance degradation or safety accidents caused by overheating. At the same time, by using a soft material liner as a cushioning and protective inner lining, the protective performance of the redundant hot backup power supply is improved, reducing damage from external impacts, extending its service life, and enhancing safety.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
