Description

Mounting assembly for UPS and UPS

Technical Field

The application relates to the technical field of UPS installation, in particular to an installation component for a UPS and the UPS.

Background

UPS is a commonly used electrical device. One existing manner of installing a UPS is to suspend the UPS on a hanger. This approach can lead to unstable UPS placement. Furthermore, this hanging is only suitable for hanging UPSs on vertical walls, but it is not suitable for walls such as horizontal roofs, which can lead to falling off of the UPS.

Accordingly, there is a need in the industry to design a mounting assembly that is simple and easy to implement and that is capable of mounting a UPS on any wall.

Disclosure of Invention

The present application aims to provide a mounting assembly for a UPS that solves at least some of the above-mentioned problems.

The present application is also directed to a UPS employing the improved mounting assembly described above.

According to one aspect of the present application, there is provided a mounting assembly for a UPS, wherein the UPS has a housing, the mounting assembly including a bracket having a body and an engagement arm extending from the body, the engagement arm having a first detent catch; and a second positioning clamping part which is suitable for being connected or arranged on the shell and forms concave-convex positioning fit with the first positioning clamping part. The male and female positioning engagement may be achieved in that the first positioning and clamping portion forms an opening or a recess, and the second positioning and clamping portion forms a protrusion that can be clamped into the opening or the recess. Alternatively, the first detent engagement portion forms a protrusion and the second detent engagement portion forms an opening or recess. The locking structure can be formed on the bracket and the housing by means of a concave-convex positioning fit. This allows the UPS to be securely suspended from any mounting base, such as a horizontal ceiling. In the mounting assembly, the second locating clip may be machined as a separate piece or as part of a separate piece and assembled with the housing of the UPS by means, either inside or outside the housing. Such as adhesive, fusion bonding, or screw attachment. Either directly to the housing or via an intermediate connection. Alternatively, the second positioning clamping portion may be integrally formed with the housing.

Preferably, the engagement arm has a first portion and a second portion, the second portion forming the first detent catch; the mounting assembly comprises an elastic arm which is suitable for being connected with or arranged on the shell and is suspended from the shell, and the free end of the elastic arm forms the second positioning clamping part; wherein the engagement arm is configured such that during movement of the bracket relative to the resilient arm to engage the housing, the first portion contacts the resilient arm and biases the resilient arm prior to the second portion until the first detent and the second detent are engaged together.

The free end of the resilient arm is biased away from its initial position by the first portion of the engagement arm, and the free end of the resilient arm then generates a counter force against the biasing force, whereby when the second portion of the engagement arm is subsequently aligned with the free end of the resilient arm, the free end of the resilient arm automatically snaps together with the second portion of the engagement arm, thereby forming a self-locking arrangement therebetween. This allows the UPS to be securely suspended from any mounting base, such as a horizontal ceiling. In the mounting assembly, the resilient arms may be machined as separate pieces and assembled with the housing of the UPS by means of either the inside or outside of the housing. Such as adhesive, fusion bonding, or screw attachment. Either directly to the housing or via an intermediate connection. Alternatively, the resilient arm may be integrally formed directly with the housing of the UPS from the same material.

Preferably, the resilient arm has a connection end connected to the housing and during movement of the bracket relative to the resilient arm to engage the housing, the first portion contacts the connection end prior to the second portion and moves from the connection end towards the free end to bias the resilient arm. The spring arms have a draft angle from the connecting end to the free end. Structurally, the free ends of the spring arms are offset from the housing more than the connecting ends. Thus, when moving along the elastic arm from the connecting end to the free end, the reaction force applied to the joint arm by the free end is larger as the free end approaches the free end, so that the elastic arm and the joint arm are more favorable to form firm and stable self-locking.

Preferably, the resilient arm is connected to the housing within the housing, the housing having an opening through which the engagement arm passes to access the resilient arm. This provides a way of arranging the resilient arms relative to the housing.

Preferably, the mounting assembly includes a support plate disposed on the inner side of the housing adjacent the opening, the resilient arm being connected to the support plate and the free end of the resilient arm extending away from the support plate. The support plate may be machined as a separate piece and assembled with the housing of the UPS in a manner. Such as adhesive, fusion bonding, or screw attachment. Alternatively, the support plate may be integrally formed directly with the housing of the UPS from the same material.

Preferably, the support plate has a guide plate along which the engagement arm moves relative to the resilient arm to approximate the resilient arm.

Preferably, the engagement arm comprises: a first arm segment connected to the body; and a second arm segment connected at an angle to the first arm segment, an end of the second arm segment remote from the first arm segment forming the first portion and the second portion.

Preferably, the first locating engagement portion comprises a bayonet formed on the engagement arm and the second locating engagement portion comprises a projection insertable into the bayonet.

Preferably, the body has a locating hole, and the mounting assembly includes a locating piece capable of passing through the locating hole and immovably mounting the bracket on the mounting base. The positioning element may be a screw, for example.

According to another aspect of the present application, there is provided a UPS including: a housing; and a mounting assembly for fixedly mounting the housing on a mounting base; wherein, the installation component is aforesaid installation component.

Additional features and advantages of the application will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following, or may be learned from the practice of the application.

Detailed Description

Referring now to the drawings, illustrative versions of the disclosed device are described in detail. Although the drawings are provided to present some embodiments of the application, the drawings are not necessarily to scale and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. The position of part of components in the drawings can be adjusted according to actual requirements on the premise of not affecting the technical effect. The appearances of the phrase "in the drawings" or similar language in the specification do not necessarily refer to all figures or examples.

Certain directional terms used hereinafter to describe the drawings, such as "inner", "outer", "above", "below" and other directional terms, will be understood to have their normal meaning and refer to those directions as they would be when viewing the drawings. Unless otherwise indicated, directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," and the like, as used herein, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

A UPS according to one embodiment of the present application is illustrated in fig. 1, 3, 8 and 9, wherein the UPS is indicated generally by the reference numeral 1. In the illustrated embodiment, the UPS1 includes a housing 2 and a bracket 3 for securing the housing 2 to a mounting base. The installation foundation is, for example, a wall surface, a plate surface, a wall surface, or the like, which can be arranged perpendicular to a horizontal plane, parallel to the horizontal plane, or inclined at an acute angle or an obtuse angle to the horizontal plane, and can be used for carrying the UPS 1. As shown, the housing 2 may be a split structure including a front face mask 20 and a back plate 21 that are detachably connected, for example, by screws. The front face mask 20 and the back plate 21 together define an interior space that accommodates components provided for UPS functions.

Referring to fig. 4 to 7, the back plate 21 is formed with an opening 210 communicating with the inner space. A support plate 22 is attached to the inner side surface of the back plate 21 at a position close to the opening 210. The support plate 22 is preferably integrally formed with the back plate 21. The support plate 22 protrudes toward the inner space of the housing 2. The support plate 22 is connected to the elastic arm 4. The resilient arms 4 are preferably integrally formed with the support 22. One end of the elastic arm 4 is joined to the stay 22 as a connection end 41, and the other end extends as a free end 42 in a direction away from the connection end 41. The spring arms 4 may be tapered from the connecting end 41 to the free end 42 such that the free end 42 is offset from the support 22. A positioning and locking portion, such as a projection 421, is formed at the free end 42 of the elastic arm 4.

Under normal conditions, which are not subjected to external forces, the free end 42 of the resilient arm 4 remains in the initial position together with the projection 421. When subjected to an external force, the free end 42 of the resilient arm 4 is biased away from the initial position together with the projection 421, while the free end 42 of the resilient arm 4 generates a counter force against the biasing force to assist the return of the free end 42 to its initial position. Since the resilient arm 4 forms a draft angle from the connecting end 41 to the free end 42, when the urging member moves in a direction from the connecting end 41 to the free end 42 and keeps biasing the resilient member 4 all the time during the movement, the closer to the free end 42, the larger the reaction force the resilient arm 4 exerts on the urging member, and the closer the urging member is to the resilient arm 4.

Referring to fig. 2, the bracket 3 includes a body 31 and an engagement arm 32 connected to the body 31. The bracket 3 may be made of metal to increase strength and reduce wear when engaged with the resilient arm 4, while providing a more compact fit with the resilient arm 4. The bracket 3 may be integrally formed. The body 31 has a positioning hole 310 through which a positioning member 5 such as a screw can pass and immovably connect the bracket 3 to the mounting base. The first arm segment 320 of the engagement arm 32 extends from the body 31, while the second arm segment 321 of the engagement arm 32 is connected to the first arm segment 320 and extends at an angle to the first arm segment 320.

The second arm section 321 of the engagement arm 32 is formed at its end remote from the first arm section 320 with a positioning snap-fit, for example a bayonet 322, which bayonet 322 is able to receive a projection 421 of the free end 42 of the resilient arm 4 and form a snap-fit with this projection 421. Specifically, during movement of the housing 2 in a direction approaching the bracket 3 to fix the housing 2 to the bracket 3, the engagement arm 32 of the bracket 3 passes through the opening 210 in the back plate 21 to access the resilient arm 4 located inside the housing 2, in particular, to the connection end 41 of the resilient arm 4. The end edge portion 323 of the second arm section 321 of the engagement arm 32 then engages the connecting end 41 of the resilient arm 4 first. The housing 2 is then moved such that the end edge portion 323 of the second arm section 321 is moved along the resilient arm 4 from the connecting end 41 to the free end 42, and in the process the engagement arm 32 always biases the resilient arm 4 away from the initial position. The bayonet 322 of the second arm segment 321 engages the connecting end 41 of the resilient arm 4 after the end edge portion 323.

As described above, when the second arm section 321 moves from the connection end 41 to the free end 42 of the elastic arm 4 and constantly biases the elastic arm 4, the reaction force applied to the second arm section 321 by the elastic arm 4 increases as the free end 42 of the elastic arm 4 is positioned closer. Thus, when the second arm section 321 is moved to the point where its end edge portion 323 leaves the projection 421 of the free end 42 of the resilient arm 4, and the bayonet 322 of the second arm section 321 is aligned with the projection 421, the projection 421 automatically and securely engages into the bayonet 322 (as shown in fig. 7) under the influence of the reaction force, so that the free end 42 of the resilient arm 4 and the second arm section 321 of the engagement arm 32 form a stable self-lock.

In another embodiment, a protrusion may be formed on the engagement portion of the bracket, and an opening may be formed on the elastic arm. The opening may also be modified as a recess.

In other embodiments, the mounting assembly may not form the resilient arm 4, but rather an opening or projection is provided in the housing 2, either directly formed by the housing 2 being integrally formed on the outside or inside during machining, or by a part that can be machined separately and assembled to the housing 2, while the engagement arm 32 of the bracket 3 is resilient, or at least the end edge portion 323 of the second arm section 321 of the engagement arm 32 is resilient, such that when the engagement arm 32 is engaged with the housing 2, the resilient nature of the engagement arm 32 is such that it presses against the housing 2 until the detent tabs of the engagement arm 32 engage with the detent tabs of the housing 2, the two detent tabs being snapped together by means of the resilience of the engagement arm 32.

The length of the opening 210 of the housing 2 may be set to be substantially the same as the overall height of the engagement arm 32, while the projection 421 of the resilient arm 4 is set higher than the upper edge of the opening 210, so that when the engagement arm 32 passes through the opening 210, the projection 421 of the resilient arm 4 does not immediately engage with the bayonet 322 of the engagement arm 32, but rather is embedded in the bayonet 322 after the engagement arm 32 moves into place along the resilient arm 4 from the connection end 41 to the free end 42. Alternatively, the length of the opening 210 of the housing 2 may be greater than the overall height of the engagement arm 32, and the position of the projection 421 of the resilient arm 4 may correspond to the position of the opening 210, but the path of movement of the engagement arm 32 is limited to avoid the bayonet 32 directly engaging with the projection 421 of the resilient arm 4 when the engagement arm 32 is passed through the opening 210 to access the resilient arm 4. For example, referring to fig. 6 and 7, a guide plate 23 may be formed on the support plate 22. When the engagement arm 32 passes through the opening 210 of the housing 2 to access the resilient arm 4, the engagement arm 32 may rest on the guide plate 23 and move along the guide plate 23 so that the engagement arm 32 is more accurately positioned near the connecting end 41 of the resilient arm 4.

Although in the illustrated embodiment the engagement arms 32 and the resilient arms 4 are each arranged in pairs, it will be appreciated by those skilled in the art that the engagement arms 32 and the resilient arms 4 may each be provided with only 1, provided that the engagement arms 32 are capable of biasing the resilient arms 4 such that the protrusions 421 of the free ends 42 of the resilient members 4 automatically fall into the bayonets 322 of the engagement arms 32.

Furthermore, the engagement arm 32 may be provided in other configurations than the "L" shape shown in the figures, such as a "one" shape. That is, the engagement arm comprises only a first arm segment extending from the body, and the bayonet is formed at an end of the first arm segment remote from the body.

It should be understood that although the present disclosure has been described in terms of various embodiments, not every embodiment is provided with a separate technical solution, and this description is for clarity only, and those skilled in the art should consider the disclosure as a whole, and the technical solutions in the various embodiments may be combined appropriately to form other embodiments that will be understood by those skilled in the art.

The foregoing is illustrative of the present application and is not to be construed as limiting the scope of the application. Any equivalent alterations, modifications and combinations thereof will be effected by those skilled in the art without departing from the spirit and principles of this application, and it is intended to be within the scope of the application.
