Description

Technical Field

[0001] This utility model relates to installation components, and more particularly to a rack-mounted uninterruptible power supply installation component for a control cabinet. Background Technology

[0002] A rack-mounted uninterruptible power supply (UPS) is an uninterruptible power supply device that integrates power protection functions with the advantages of rack mounting. Within the control cabinet, a rack-mounted UPS can ensure the power continuity and stability of the control circuit, avoiding control equipment failure due to power grid anomalies (such as power outages, voltage fluctuations, electromagnetic interference), which could lead to production interruptions, equipment damage, or safety accidents.

[0003] Currently, there are two main installation methods for rack-mounted uninterruptible power supplies (UPS) within control cabinets: The first method involves welding the UPS's built-in connecting lugs on both sides of the chassis to the cabinet's internal columns. However, this welding method requires electroplating of the mounting components and materials, which is not only costly and prevents disassembly, but also results in inconsistent welding quality due to varying operator skill levels, leading to defective products and affecting cabinet stability and strength. The second method involves the UPS's built-in connecting lugs on both sides of the chassis working in conjunction with rack rails. These rack rails are used in pairs (one on each side) and bolted to the cabinet's internal columns. However, these rack rails are only located on the left and right sides, lacking bottom support. This causes the UPS's weight to concentrate on the connection between the connecting lugs and the rack rails, leading to loosening and deformation over time, thus compromising installation reliability. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a rack-mounted uninterruptible power supply (UPS) mounting assembly for control cabinets.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a rack-mounted uninterruptible power supply mounting assembly for a control cabinet, comprising: The base support frame is assembled and connected to the uprights inside the control cabinet. Assemble the guide rail brackets connected to the base support frame. The guide rail brackets are L-shaped and symmetrically arranged in two sets. The two sets of guide rail brackets are distributed on the left and right sides above the base support frame. The ear-mounted bracket is assembled and connected to the column inside the control cabinet. There are two sets of ear-mounted brackets, which are distributed at both ends of the front side of the base support.

[0006] Preferably, the ear-hanging bracket has an L-shaped main body, and baffles are formed at the top and bottom of the L-shaped main body.

[0007] Preferably, the front wall of the L-shaped main body of the ear bracket is provided with an ear-mounted rivet nut, and the side wall of the L-shaped main body of the ear bracket is provided with an ear-mounted fixing hole.

[0008] Preferably, the base support includes multiple support bracket units, which are arranged in parallel at intervals and located on the same horizontal plane.

[0009] Preferably, each support bracket unit is provided with a support bracket rivet nut, and each support bracket unit has support bracket fixing holes at both ends.

[0010] Preferably, the guide rail bracket has guide rail fixing holes on its flat plate.

[0011] Preferably, the mounting assembly also includes a reinforcing brace with the same structure as the individual support bracket unit.

[0012] Preferably, a limiter is installed at the location of the support frame rivet nut on the reinforcing support frame.

[0013] Preferably, the horizontal plate of the limiter has a waist-shaped fixing hole.

[0014] Preferably, the mounting assembly also includes binding brackets that are perpendicular to the reinforcing support;

[0015] The front side of the binding bracket is equipped with multiple binding buckles, and the two ends of the binding bracket are provided with binding bracket fixing holes.

[0016] This utility model discloses a mounting assembly for a rack-mounted uninterruptible power supply (UPS) within a control cabinet. A base bracket supports the UPS at its bottom, thus improving the stress concentration problem of traditional rack-mounted installations and effectively enhancing the reliability of the UPS within the control cabinet. Simultaneously, the mounting lugs and guide rail brackets work together to limit and secure the UPS, providing a more stable fixation while maintaining simple and flexible installation. Furthermore, compared to traditional welding methods, this new mounting structure eliminates the complex welding process, ensuring installation quality and effectively maintaining cabinet strength, making it suitable for installing large-scale UPSs.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment discloses a rack-mounted uninterruptible power supply (UPS) mounting assembly for a control cabinet. The mounting assembly is fastened to the control cabinet's uprights using screws, and the rack-mounted UPS is also detachably fixed to the mounting assembly using screws. The entire installation process requires no welding, saving costs and time, and effectively maintaining the strength of the control cabinet. Furthermore, the mounting assembly has a simple structure, is easy to fix and disassemble, and provides reliable installation stability for the rack-mounted UPS while also offering advantages such as convenient installation and low operational difficulty.

[0028] like Figure 1 The diagram shown is an overall structural schematic of the rack-mounted uninterruptible power supply mounting assembly in the control cabinet disclosed in this embodiment. Its main structural components include: a base support 1, a guide rail bracket 2, and a hanging ear bracket 3. Among them, the base support 1 provides support below the uninterruptible power supply, such as... Figure 1As shown, the base support 1 includes multiple support bracket units 11, which are arranged in parallel at intervals and located on the same horizontal plane. There is a certain gap between each support bracket unit 11 of the base support 1. After the rack-mounted uninterruptible power supply is installed on this mounting structure, the gap falls directly below the rack-mounted uninterruptible power supply, which can play a role in heat dissipation and prevent the power supply from overheating.

[0029] For example Figure 5 As shown, each support bracket unit 11 has support bracket fixing holes 13 at both ends. The support bracket fixing holes 13 are aligned with the pre-set openings on the columns inside the control cabinet. After the screws are locked in together, the support bracket unit 11 can be installed inside the control cabinet.

[0030] Meanwhile, each support bracket unit 11 is provided with a support bracket rivet nut 12, which is used for the assembly and connection of the guide rail bracket 2 on the base support bracket 1.

[0031] Guide rail bracket 2 is an L-shaped bent structural component, such as Figure 4 As shown, the guide rail bracket 2 has a guide rail fixing hole 21 on its flat plate. After the guide rail fixing hole 21 is aligned with the support bracket unit 11 and the support nut 12 is riveted, the fixing screws are locked in together to satisfy the detachable assembly connection of the guide rail bracket 2 on the base support 1.

[0032] Furthermore, as well as Figure 1 As shown, two sets of guide rail brackets 2 are symmetrically arranged on the base support 1. The two sets of guide rail brackets 2 are distributed on the left and right sides above the base support 1. After the bracket-type uninterruptible power supply is placed on the base support 1, the guide rail brackets 2 can be limited on the left and right sides.

[0033] The ear bracket 3 is assembled and connected to the column inside the control cabinet, and there are two sets of ear brackets 3, which are distributed at the two ends of the front side of the base support 1.

[0034] like Figure 3 As shown, the ear-hanging bracket 3 is an integral bent part, which has an L-shaped main body 31, and baffles 32 are formed by bending at the top and bottom of the L-shaped main body 31.

[0035] The front wall of the L-shaped main body 31 of the ear bracket 3 is provided with an ear rivet nut 33, which is used for assembling and connecting the ear bracket of the uninterruptible power supply. The side wall of the L-shaped main body 31 of the ear bracket 3 is provided with an ear fixing hole 34, which is aligned with the pre-set opening on the column inside the control cabinet. After the screws are locked in together, the ear bracket 3 can be installed in the control cabinet.

[0036] Furthermore, it should be noted that the left and right mounting brackets 3 can be customized according to the model of the rack-mounted uninterruptible power supply (UPS) and the size of the power supply's own connecting brackets. After the connecting brackets are inserted into the front of the guide rail bracket 2, they fit snugly against the mounting brackets 3, and then the UPS is fixed in place by screws. The baffle part of the mounting bracket 3 can, to a certain extent, enhance the limiting and fixing effect.

[0037] Therefore, for the rack-mounted uninterruptible power supply installation assembly in the control cabinet disclosed in this embodiment, during installation, first align and fit the mounting holes 34 of the mounting brackets 3 at the left and right positions with the modular holes on the columns or beams inside the cabinet, and tighten them with screws of the corresponding specifications to complete the installation of the mounting brackets 3; then align and fit the support fixing holes 13 on the base support 1 with the modular holes on the columns or beams inside the cabinet, and tighten them with screws of the corresponding specifications to complete the installation of the base support 1; then align and fit the guide rail fixing holes 21 on the guide rail bracket 2 with the support rivet nuts 12 on the base support 1, and tighten them with the corresponding screws to complete the installation of the symmetrically distributed guide rail brackets 2.

[0038] Subsequently, the rack-mounted power supply is installed on its main body bracket (i.e., the connecting ear bracket). The rack-mounted uninterruptible power supply is then placed on the base support 1. The guide rail bracket is positioned on the left and right sides. The connecting ear bracket is inserted into the gap on the front side of the guide rail bracket and fits against the hanging ear bracket. The modular hole on the connecting ear bracket is aligned and fitted with the hanging ear rivet nut 33 on the hanging ear bracket. The corresponding screws are screwed in and tightened, thus completing the installation of the rack-mounted uninterruptible power supply on the installation components in this embodiment.

[0039] Example 2

[0040] This embodiment discloses a rack-mounted uninterruptible power supply (UPS) installation assembly in a control cabinet. Based on the structure disclosed in Embodiment 1, it further adds a reinforcing support 4, a limiter 6, and a binding bracket 5.

[0041] The reinforcing support 4 has the same structural configuration as the support bracket unit 11 of the base support 1, and also has a support fixing hole 13 for connecting with the uprights inside the cabinet, and a support pressing nut 12.

[0042] Unlike the support bracket unit 11, the support bracket 4's support rivet nut 12 is used for assembly connection with the limiter 6. For example... Figure 7 As shown, the limiter 6 has a waist-shaped fixing hole 61. The waist-shaped fixing hole 61 and the support rivet nut 12 of the reinforcing support 4 are locked together with screws to complete the installation of the limiter 6.

[0043] The limit switch 6 is located on the rear side of the rack-mounted uninterruptible power supply, which enhances the limiting function and prevents the rack-mounted power supply from becoming loose due to vibration during transportation.

[0044] Preferably, a binding bracket 5 is further provided, which is perpendicular to the reinforcing support 4; such as Figure 6 As shown, the binding bracket 5 has binding bracket fixing holes 52 at both ends, which are used to align with the openings on the uprights inside the cabinet. After the screws are tightened together, the binding bracket 5 can be installed inside the control cabinet.

[0045] Multiple binding buckles 51 are provided on the front side of the binding bracket 5. If wires or cables need to pass through the back of the rack-mounted uninterruptible power supply, they can be bound and fixed by the binding buckles 51 and cable ties on the binding bracket 5 to prevent the wires and cables from being messy and achieve a neat and beautiful effect.

[0046] Furthermore, it should be noted that the difference between the installation structures of Embodiment 1 and Embodiment 2 for the same model of bracket-type uninterruptible power supply is as follows: In Embodiment 1, the base support 1 has three support bracket units 11, and the guide rail bracket is fixed on the three support bracket units 11. The bracket-type uninterruptible power supply is then placed on the three support bracket units 11 for installation. In Embodiment 2, the last support bracket unit 11 is replaced with a reinforcing support 4. The guide rail bracket is based on two support bracket units 11. After the bracket-type uninterruptible power supply is placed and installed on the two support bracket units 11 and the reinforcing support 4, the limiter 6 can play a reinforcing limiting role at the rear of the bracket-type power supply.

[0047] In summary, the rack-mounted uninterruptible power supply mounting assembly for control cabinets disclosed in this invention has the following specific technical advantages: 1) The number of openings in the entire structure is reduced, and no welding operation is required when it is used for the installation of uninterruptible power supplies. This saves costs, time and reduces the difficulty of operation, while also strengthening the structural strength. This makes the overall stability of the installation component structure stronger after it is installed in the cabinet.

[0048] 2) The base support is used to prevent the load on this installation component from being concentrated at one point during the load-bearing process, which would cause damage to the component and improve the reliability of the uninterruptible power supply installation.

[0049] 3) The base support is composed of spaced support bracket units, with the gaps between them located below the rack-mounted uninterruptible power supply, which can effectively prevent the power supply from overheating and improve safety.

[0050] 4) The guide rail bracket and the hanging ear bracket are used for limiting and fixing. The limiter and the binding bracket are used for further limiting and fixing at the rear, so that the bracket-type uninterruptible power supply is firmly installed on this installation component.

[0051] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
