CDU chassis

Abstract

A CDU chassis, which relates to the technical field of temperature control devices. The CDU chassis comprises a chassis body and a display screen module, wherein a front cover plate is fixedly arranged at the front end of the chassis body, and the display screen module is movably connected to the front cover plate, and is angularly adjustable relative to the front cover plate. Since a display screen module is movable, an operator can freely adjust a viewing angle on the basis of requirements, thereby improving the comfort in use. In addition, since the display screen module moves relative to a front cover plate during angle adjustment, the front cover plate does not need to move together therewith and can remain in a state of covering the front portion of a chassis body, thereby reducing the impact of the movement of the display screen module on the protective capability of the front cover plate.

[0002] This application relates to the field of temperature control equipment technology, and in particular to a CDU chassis. Background Technology

[0003] An existing CDU (Cooling Distribution Unit) system has its display module fixed to the front panel of the enclosure. When staff members want to view the display module, they need to change their viewing angle, which is inconvenient and uncomfortable.

[0004] Therefore, improving the comfort of viewing the display module is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a CDU chassis that improves the comfort of viewing the display module.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A CDU chassis includes a chassis and a display module. A front cover is fixedly disposed at the front end of the chassis, and the display module is movably connected to the front cover, and the display module can be angled relative to the front cover.

[0008] Preferably, the display module is rotatably connected to the housing via a damped rotating component, so that the display module can be held at the adjusted angle.

[0009] Preferably, the display module is rotatably connected to the front cover plate.

[0010] Preferably, the top of the display module is connected to the front cover plate.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The core of this application is to provide a CDU chassis that improves the comfort of staff viewing the display module.

[0036] The first specific embodiment of the CDU chassis provided in this application is shown in Figures 1 to 3, which includes a chassis 1 and a display module 2. A front cover 11 is fixedly installed at the front end of the chassis 1, and the display module 2 is movably connected to the front cover 11, and the display module 2 can be angled relative to the front cover 11.

[0037] In this application, the front cover 11 of the housing 1 is positioned horizontally at one end as the front end, and the opposite end is the rear end. The space inside the housing 1 located behind the display module 2 is used to accommodate the required functional components. Operators can view and operate the display module 2 from the front of the front cover 11.

[0038] The display module 2 can be a touch screen capable of human-computer interaction, or other displays, such as non-touch screens and corresponding physical buttons.

[0039] It should be noted that the staff mainly examines the display surface 21 of the display module 2. Within at least a portion of the movable range of the display module 2 relative to the front cover 11, the surface of the display module 2 exposed on the housing 1 includes its display surface 21, allowing the staff to view it from the outside and further perform touch screen operations on the display module 2. As shown in the embodiments of Figures 1 to 3, the display surface 21 of the display module 2 (corresponding to the right side in Figure 1) is always exposed on the front cover 11, while in the embodiments of Figures 4 to 7, the display surface 21 of the display module 2 (corresponding to the top surface in Figure 5) is exposed on the front cover 11 within a certain range of motion.

[0040] During use, the cabinet 1 is usually in a low position, and the height of the operator's head is generally higher than that of the display module 2. Adjusting the angle of the display module 2 relative to the front cover 11 usually requires rotating the display surface 21 of the display module 2 to face upwards to accommodate the operator's downward viewing angle. The tilt angle of the display module 2 after it is flipped relative to the front cover 11 (with the display surface 21 located above the display module 2) is related to the height of the operator's head (mainly eye level). The higher the head, the larger the tilt angle (the angle between the display module 2 and the vertical plane), and the lower the head, the smaller the tilt angle. Of course, the tilt angle is also related to the horizontal distance, that is, the horizontal distance between the display module 2 and the operator. The greater the distance, the smaller the tilt angle, and the smaller the distance, the larger the tilt angle.

[0041] In this embodiment, since the display module 2 is movable, the operator can freely adjust the viewing angle as needed, improving user comfort. Furthermore, because the display module 2 moves relative to the front cover 11 when adjusting the angle, the front cover 11 does not need to move with it, maintaining its closed position at the front of the housing 1. This reduces the impact of the display module 2's movement on the protective capability of the front cover 11.

[0042] To further improve the viewing comfort of the display module 2, as shown in Figure 1, the display module 2 is rotatably connected to the housing 1 via a damped rotating component 3, so that the display module 2 can be maintained at the adjusted angle. Since the display module 2 can be angled relative to the front cover 11 within its rotatable range and maintained at the current angle, it eliminates the need for staff to constantly hold it, making viewing more convenient.

[0043] When in use, if display module 2 is stationary at its current tilt angle, the torque generated by its center of gravity is insufficient to overcome the damping of rotating component 3, keeping display module 2 in its current position. When rotation is required, the operator can directly apply a force (torque) to display module 2. If the force is applied in the direction of the torque generated by the center of gravity, the sum of the applied torque and the torque generated by the center of gravity is sufficient to overcome the damping, thus allowing display module 2 to rotate. However, if the force is applied against the direction of the torque generated by the center of gravity, it must overcome both the torque generated by the center of gravity and the damping to rotate display module 2. Therefore, the damping should not be too large, as this would require a large force from the operator, making operation inconvenient; nor should it be too small, sufficient to overcome the torque generated by the center of gravity. Of course, display module 2 can also be subjected to other forces that generate torque, analyzed in the same way as the torque generated by the center of gravity described above.

[0044] The rotating component 3 can be a damped hinge or a damped shaft. Alternatively, the rotating component 3 can be a ball joint structure or a line hinge structure. A line hinge structure may be hinged via a pin. The rotation axis of the line hinge structure preferably extends horizontally and can be parallel to or coplanar with the front cover plate 11. In other embodiments, the rotating component 3 can also be a gear transmission structure; or, the rotating component 3 can also include a rotation drive mechanism, which allows the angle of rotation of the display module 2 to be selected via buttons or knobs on the front cover plate 11 or the display module 2, thereby controlling the rotation drive mechanism to automatically drive the display module 2 to rotate into position; if necessary, the rotating component 3 may also be without damping.

[0045] To simplify the structure, as shown in Figure 1, the display module 2 is directly rotatably connected to the front cover plate 11 via the rotating component 3. Specifically, the top of the display module 2 is rotatably connected to the front cover plate 11. At this time, the display module 2 can be flipped up directly relative to the front cover plate 11 to adjust the viewing angle, which can be adapted to applications where the display module 2 is positioned low. As shown in Figures 1 to 3, the display module 2 can be flipped upward from its reset state with its front surface parallel to the front cover plate 11, rotating up to 90°, allowing the operator to directly view the display module 2 vertically downward.

[0046] To improve the protection of the display module 2, as shown in Figure 1, after the display module 2 moves to the reset state relative to the front cover 11, it does not protrude forward from the front cover 11. Additionally, the rotating component 3 can be housed within the housing 1 to maintain the aesthetic appearance of the housing 1.

[0047] Specifically, the front cover 11 has an insert, and the display module 2 moves into the insert in the reset state. When the display module 2 is accommodated in the insert, it is protected by the housing 1, making the device more compact. Of course, the display module 2 in the reset state may not protrude from the front panel 11; specifically, the outer surface of the insert is located on the outer front side of the display module 2 in the reset state. The display module 2 in the reset state can still move out of the insert to be located on the front side of the front panel 11, so that it can be rotated to adjust the angle to accommodate the operator.

[0048] Specifically, as shown in Figures 1 and 2, a through-hole mounting hole 111 is provided on the front cover plate 11 to serve as the aforementioned insertion port for accommodating the display module block 2. The display module 2 is connected to the mounting hole 111 on the front cover plate 11. After the display module 2 is reset, it can cover the mounting hole 11.

[0049] Alternatively, the display module 2 can enter and exit the insertion port through the rotational connection of the rotating component 3. In this case, the insertion port can be a groove. The rotating component 3 can be set on the upper edge of the groove, in which case the display module 3 can rotate around the upper edge to disengage from the insertion port, and can continue to rotate after disengagement. In this case, the display surface 21 is the front side. Alternatively, the rotating component 3 can be set on the lower edge of the groove 3, in which case the display module 3 can rotate around the lower edge forward to disengage from the insertion port, and can be tilted. In this case, the display surface 21 is the rear side.

[0050] Of course, in other embodiments, as shown in Figures 8 and 9, the front cover plate 11 may not have an insertion opening and may remain protruding from the front surface of the front cover plate 11, and the display screen module may be connected to an appropriate position on the front surface of the front cover plate 11.

[0051] Alternatively, the display module 2 can be connected to the housing 1 or the front cover 11 in other ways. As shown in Embodiment 2 of Figures 4 to 7, a movable component 12 is also provided on the housing 1, and the display module 2 is rotatably connected to the movable component 12. By adding the movable component 12, the range of motion of the display module 2 can be increased.

[0052] At this point, the rotating component 3 is positioned between the moving component 12 and the display module 2. The rotating component 3 can be a damped hinge or damped shaft connecting the display module 2 and the moving component 12, or it can be other rotating components without damping to achieve a rotational connection. The angle at which the display module 2 can rotate relative to the moving component 12 can be 360° or other angles.

[0053] Specifically, as shown in Figure 5, the center line of rotation of the display module 2 relative to the front cover 11 is parallel to the front cover and the horizontal direction. Specifically, it can be located in the middle of the display module 2 or in the middle of the display module 2.

[0054] Specifically, as shown in Figures 5 and 6, the moving component 12 includes a groove 122 formed in the housing 1 and a slider 121 slidably connected to the groove 122. The display module 2 is rotatably connected to the slider 121. The opening of the groove 122 is on the front cover plate 11, and the slider 121 can extend and retract relative to the front cover plate 11, resulting in good movement stability.

[0055] To prevent the slider 121 from disengaging from the slide groove 122, a limiting block can be provided at one end of the slide groove 122 near the front cover plate 11. The slider 121 moves outward to meet the limiting block, thus preventing the slider 121 and the display module 2 from disengaging from the housing 1.

[0056] Furthermore, as shown in Figures 4 and 5, the display module 2 can retract into the slide groove 122 along with the slider 121. Specifically, it can retract along with the slider 121 after being rotated to an appropriate angle. Since the display module 2 can retract into the housing 1, it has a protective effect. At this time, the display module 2 does not protrude forward from the front cover plate 11.

[0057] The location of the slide groove 122 within the housing 1 is preferably in a relatively empty area of ​​the housing 1 to avoid affecting the assembly of other equipment within the housing 1. For example, the opening of the slide groove 122 on the front cover plate 11 is located slightly above the center of the front cover plate 11, and the slide groove 122 extends rearward from this opening. Alternatively, the opening can be rectangular to fit the shape of the display module 2.

[0058] The extension direction of the slide groove 122 has an angle with the front cover plate 11, and can be set vertically, as shown in Figure 5. The slider 121 can slide back and forth in the slide groove 122, driving the display module 2 to move back and forth. Before the display module 2 is fully extended out of the front cover plate 11, it can be flipped relative to the slider 121 and the front cover plate 11.

[0059] To ensure the stability of the rotation of the display module 2 relative to the slider 121, two sliders 121 can be provided, as shown in Figure 7, respectively located on both sides of the display module 2. Of course, in other embodiments, only one slider 121 can be provided, and the slider 121 can also be connected to the back side of the display module 2 opposite to the display surface 21.

[0060] As shown in Figures 5 and 6, with the slider 121 fully retracted into the groove 122, the slider 121 is detachably fixed to the housing 1 by the locking element 123, preventing the slider 121 and the display module 2 from moving arbitrarily after resetting. Specifically, the locking element 123 can be a latch, such as a magnetic latch, a latch bead, or a snap-fit ​​element. Furthermore, a second locking element can also be provided between the display module 2 and the housing 1, which can be designed with reference to the locking element 123 between the slider 121 and the housing 1, for example, using the same structure to further ensure the stability of the display module 2 after it retracts into the housing 1.

[0061] In addition, to ensure the protective effect of the slide 122 on the display module 2, the slide 122 can have only a single-opening mask body with an opening on the front cover plate 11, so that it can wrap around the display module 2 after it retracts, preventing the display module 2 from being affected by water and electricity from the internal structure of the housing 1. Alternatively, to achieve weight reduction, the slide 122 can also only support the U-shaped slide of the display module 2. Furthermore, the display module 2 can be electrically connected to the controller in the housing 1 via wired or wireless means.

[0062] Alternatively, to achieve angle adjustment of the display module 2 relative to the front cover plate 11, a sliding connection can be used. An arc-shaped slide rail is provided on the front cover plate 11, and the display module 2 is slidably connected to the arc-shaped slide rail to achieve angle adjustment.

[0063] It should be noted that when an element is referred to as "fixing" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as "connecting" another element, it can be directly connected to the other element or there may be an intervening element.
