[0047] In order to enable those skilled in the art to better understand the present scheme, the technical solutions in the embodiments of the present scheme will be clearly described below in conjunction with the drawings in the embodiments of the present scheme. Obviously, the described embodiments are only a part of the embodiments of the present scheme, rather than all the embodiments. Based on the embodiments in the present scheme, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present scheme.

[0048] The terms “include”, “comprise” and other any variants in the specification and claims of the present scheme and the above-mentioned drawings refer to “include but not limited to”, which is intended to cover non-exclusive inclusion, and is not limited to the examples listed in the text. In addition, the terms “first” and “second” and the like are used to distinguish different objects, rather than to describe a specific order.

[0049] The present inventors found that in order to realize the rack-mounted installation and vertical installation of the uninterruptible power supply, the display unit in the uninterruptible power supply is usually set to a structure that can be mechanically rotated, and the display unit is rotated accordingly when the installation direction of the UPS is different. However, this way needs to set an additional mechanical structure, which is complex in design and inconvenient to operate.

[0050] For the idea of quickly and conveniently adjusting the display unit, in the embodiments of the application, a tilt detection unit is arranged on the cabinet body of the UPS, the installation direction of the cabinet body of the UPS is detected through the tilt detection unit, and a first sensing signal or a second sensing signal corresponding to the installation direction is output; and the display unit is configured so that the display unit displays a picture in different preset directions according to the first sensing signal or the second sensing signal received, so that the picture displayed by the display unit is adapted to the installation direction when the installation direction of the UPS is different, and the display unit is conveniently adjusted without the need for mechanical structure adjustment.

[0051] The implementation of the application is described in detail below in combination with specific drawings:

[0052] Referring to Figure 1 The application provides an upright and horizontal uninterrupted power supply, which comprises a cabinet body 1 and a tilt detection unit 2 and a display unit 3 arranged on the cabinet body.

[0053] When the installation direction of the cabinet body 1 is horizontal, the tilt detection unit 2 outputs a first sensing signal; and when the installation direction of the cabinet body 1 is vertical, the tilt detection unit 2 outputs a second sensing signal.

[0054] The display unit 3 is configured to display a picture in a first preset direction when the first sensing signal is detected, and display a picture in a second preset direction when the second sensing signal is detected.

[0055] In the embodiment, the tilt detection unit 2 can detect different states of the cabinet body 1 when the installation direction of the cabinet body 1 is different, so that different sensing signals can be output. The sensing signals can be voltage values, current values and resistance values, etc.

[0056] The display unit 3 is configured with different display modes, and when the display unit 3 receives different sensing signals, the display unit 3 presents different display modes, i.e. displays a picture in different preset directions.

[0057] The first preset direction in which the display unit 3 displays a picture matches the horizontal installation direction of the cabinet body 1, i.e. when the installation direction of the cabinet body 1 is horizontal, the picture displayed by the display unit 3 is horizontal, i.e. the display is horizontal in the horizontal installation direction. The second preset direction in which the display unit 3 displays a picture matches the vertical installation direction of the cabinet body 1, i.e. when the installation direction of the cabinet body 1 is vertical, the picture displayed by the display unit 3 is vertical, i.e. the display is vertical in the vertical installation direction, which is convenient for users to view in different installation directions.

[0058] For example, taking the sensing signal as a voltage value as an example, when the installation direction of the cabinet 1 is transverse, the inclination detection unit 2 outputs a first sensing signal with a voltage value of 2V, and when the display unit 3 receives the first sensing signal with a voltage value of 2V, the display unit 3 displays a picture in a first preset direction. Here, the first preset direction matches the transverse installation direction of the cabinet.

[0059] The embodiment of the utility model discloses an inclination detection unit arranged on the cabinet of the uninterruptible power supply, which can detect the inclination of the cabinet, wherein when the installation direction of the cabinet is transverse, the inclination detection unit can output a first sensing signal, and when the installation direction of the cabinet is vertical, the inclination detection unit can output a second sensing signal, so that the installation direction of the uninterruptible power supply can be distinguished by the first sensing signal and the second sensing signal. When the display unit detects the first sensing signal, the display unit displays a picture in a first preset direction, and when the display unit detects the second sensing signal, the display unit displays a picture in a second preset direction, so that the display unit can display a picture in different directions in response to different sensing signals, so that the picture displayed by the display unit matches the installation direction of the uninterruptible power supply, and the display unit does not need to be rotated by an additional mechanical structure, and the display unit can be quickly and conveniently adjusted.

[0060] In some embodiments, as shown in the circuit structure schematic diagram of the inclination detection unit, Figure 2 The inclination detection unit 2 includes a power supply end Vcc, a voltage dividing resistor R1, an inclination switch SW1, a pull-down resistor R2 and a signal output end Vout. The voltage dividing resistor R1, the inclination switch SW1 and the pull-down resistor R2 are connected in series between the power supply end Vcc and the ground wire. The signal output end Vout is connected to one end of the inclination switch SW1. The power supply end Vcc is used to connect an auxiliary power supply, and the signal output end Vout is used to output a sensing signal.

[0061] Here, the inclination switch presents different resistance values when the inclination switch is at different inclination angles. For example, for a ball-type inclination switch, when the inclination angle of the inclination switch reaches a preset angle, the internal metal ball contacts the two pins at both ends, forming a conduction state, and the inclination switch presents a first resistance value, such as 10Ω. When the inclination switch is in a horizontal state and the inclination angle of the inclination switch is less than the preset angle, the internal metal ball does not contact, and the inclination switch is in an open state, and the inclination switch presents a second resistance value, such as 100MΩ.

[0062] That is, when the inclination switch is in different angle ranges, the switch state of the inclination switch changes obviously, so that the inclination switch presents different resistance values.

[0063] In the embodiment, the tilt switch SW1 is arranged in the tilt detecting unit 2. Since the positions of the tilt switch SW1 and the cabinet 1 are relatively fixed, the tilt state of the cabinet 1 can be sensed by the tilt switch SW1, so as to detect the installation direction of the cabinet 1.

[0064] When the installation direction of the cabinet 1 is horizontal, the tilt switch SW1 presents a resistance value, so that the signal output end Vout outputs a first sensing signal. When the installation direction of the cabinet 1 is vertical, the tilt switch SW1 presents another resistance value, so that the signal output end Vout outputs a second sensing signal.

[0065] In addition, the signal output end Vout can be a voltage output end, and the voltage signal is used as the sensing signal.

[0066] Optionally, the signal output end Vout can be arranged at the joint of the voltage dividing resistor R1 and the tilt switch SW1, in addition to the position shown (the joint of the tilt switch SW1 and the pull-down resistor R2). Figure 2

[0067] In addition, a capacitor C1 can be connected in parallel to the pull-down resistor R2, so as to realize the functions of anti-jitter and filtering by the capacitor C1, and to ensure the stability of the output sensing signal.

[0068] In some embodiments, the tilt switch SW1 comprises a one-way tilt switch.

[0069] When the installation direction of the cabinet 1 is horizontal, the one-way tilt switch presents a first resistance value, and the voltage of the signal output end Vout is a first voltage, which is output to the display unit 3 as the first sensing signal.

[0070] When the installation direction of the cabinet 1 is vertical, the one-way tilt switch presents a second resistance value, and the voltage of the signal output end Vout is a second voltage, which is output to the display unit 3 as the second sensing signal.

[0071] In the embodiment, the one-way tilt switch can detect whether the tilt reaches a preset angle, and does not distinguish the direction of the tilt. The two installation directions of the cabinet 1 can be distinguished by whether the preset angle is reached or not, so as to make the signal output end Vout output different sensing signals. The one-way tilt switch has two states, one is a conduction state, and the other is an off state, so as to make the one-way tilt switch present different resistance values.

[0072] For example, when the installation direction of the cabinet 1 is horizontal, the one-way tilt switch is arranged horizontally, and the one-way tilt switch is in the off state and presents a first resistance value. When the installation direction of the cabinet 1 is vertical, the one-way tilt switch is arranged vertically, and the one-way tilt switch is in the conduction state and presents a second resistance value. ​

[0073] Alternatively, when the installation direction of the cabinet 1 is horizontal, the one-way tilt switch is vertically arranged, the one-way tilt switch is in the on state, and presents the first resistance value; when the installation direction of the cabinet 1 is vertical, the one-way tilt switch is horizontally arranged, the one-way tilt switch is in the off state, and presents the second resistance value.

[0074] The inventor considers that when the installation direction of the UPS is horizontal, there can be two horizontal installation modes, as shown in FIG. 2. Figure 3 As shown in FIG. 2, the two horizontal installation modes are relatively rotated by 180°. Since the one-way tilt switch can only detect whether the tilt angle is reached, the direction of the tilt cannot be detected, and the two horizontal installation modes cannot be distinguished. Therefore, the present application also considers that a multi-way tilt switch, such as a two-way tilt switch or a four-way tilt switch, can be used.

[0075] In some embodiments, the tilt switch SW1 includes a multi-way tilt switch.

[0076] When the installation direction of the cabinet 1 is the first horizontal direction, the multi-way tilt switch presents the third resistance value, the voltage of the signal output end Vout is the third voltage, and the third voltage is output as the first sensing signal to the display unit 3.

[0077] When the installation direction of the cabinet 1 is the second horizontal direction, the multi-way tilt switch presents the fourth resistance value, the voltage of the signal output end Vout is the fourth voltage, and the fourth voltage is output as the first sensing signal to the display unit 3.

[0078] When the installation direction of the cabinet 1 is vertical, the multi-way tilt switch presents the fifth resistance value, the voltage of the signal output end Vout is the fifth voltage, and the fifth voltage is output as the second sensing signal to the display unit 3.

[0079] In the present embodiment, the multi-way tilt switch can detect tilt in multiple directions and detect whether the tilt reaches a preset angle. When the tilt of the multi-way tilt switch in different directions reaches the preset angle, the multi-way tilt switch presents different resistance values, thereby distinguishing the direction of the tilt.

[0080] When a two-way tilt switch is used, when the installation direction of the cabinet 1 is vertical, the two-way tilt switch is horizontally placed, and the two-way tilt switch is in the off state; when the installation direction of the cabinet 1 is the first horizontal direction, the two-way tilt switch is vertically placed after being rotated to the left, the two-way tilt switch is in the on state, and presents a resistance value; when the installation direction of the cabinet 1 is the second horizontal direction, the two-way tilt switch is vertically placed after being rotated to the right, the two-way tilt switch is in the on state, and presents another resistance value, thereby distinguishing the two horizontal installation directions.

[0081] Alternatively, a four-way tilt switch can be used to sense the installation direction of cabinet 1. Specifically, different resistance values ​​of any three directions of the four-way tilt switch can be selected for detection, or different resistance values ​​of the two directions of the four-way tilt switch and the off state can be selected for detection.

[0082] Here, the tilt switch SW1 can present different resistance values ​​with a switching angle ranging from 15° to 45°, such as 17°, 20°, 30° and 40°.

[0083] In some embodiments, when the cabinet 1 is installed horizontally, the bottom surface of the tilt switch SW1 is parallel to the ground; when the cabinet 1 is installed vertically, the bottom surface of the tilt switch SW1 is perpendicular to the ground. Alternatively, when the cabinet 1 is installed horizontally, the bottom surface of the tilt switch SW1 is perpendicular to the ground; when the cabinet 1 is installed vertically, the bottom surface of the tilt switch SW1 is parallel to the ground.

[0084] In this embodiment, the positional relationship between the tilt switch SW1 and the cabinet 1 is fixed. Therefore, there is a fixed correspondence between each resistance value presented by the tilt switch SW1 and the installation direction of the cabinet 1. Thus, the installation direction of the cabinet 1 can be accurately obtained through the sensing signal output by the tilt detection unit where the tilt switch SW1 is located.

[0085] For example, with Figure 2 Taking the tilt detection unit shown as an example, when the installation direction of cabinet 1 is horizontal, the tilt switch SW1 is set vertically and is in the ON state, and the signal output terminal outputs a high level; when the installation direction of cabinet 1 is vertical, the tilt switch SW1 is set horizontally and is in the OFF state, and the signal output terminal outputs a low level. Based on this, the installation direction of cabinet 1 can be accurately obtained using the sensing signal output from the signal output terminal.

[0086] In addition, the tilt switch SW1 can be fixed on a vertical or horizontal circuit board.

[0087] In some embodiments, such as Figure 4 As shown, the display unit 3 can be provided with multiple screen display areas; each screen display area displays the screen in a different preset direction; each type of sensing signal corresponds to a screen display area.

[0088] The display unit 3 is configured to display a screen in a first preset direction in the screen display area corresponding to the first sensing signal when a first sensing signal is detected, and to display a screen in a second preset direction in the screen display area corresponding to the second sensing signal when a second sensing signal is detected.

[0089] In the embodiment, the picture display area is a position in the display unit 3 for picture display, and each picture display area displays a picture in a different direction. As shown in Figure 4 In the embodiment, the first picture display area 31 displays a first horizontal picture, and the second picture display area 32 displays a vertical picture. The display unit 3 can further include a third picture display area 33, and the third picture display area 33 displays a second horizontal picture. Figure 4 In the embodiment, the arrow in the picture display area indicates the direction of reading the text in the picture.

[0090] Since the installation direction of the cabinet 1 is different, the picture display area in which the preset direction of picture display matches the installation direction of the cabinet 1 can be selected for picture display. The display unit 3 is configured such that one sensing signal corresponds to one picture display area, so that when different sensing signals are detected, picture display is performed at the corresponding picture display area, without the need to rotate the display unit by mechanical structure.

[0091] In some embodiments, as shown in Figure 5 The display unit 3 is configured to display status information of the uninterruptible power supply; wherein the status information includes at least one item, and each item includes at least one of a number, a letter, a text, and a figure.

[0092] The display unit 3 is provided with a fixed display area A and a variable display area B; the fixed display area A is provided with a plurality of fixed-position shapes; wherein the shapes are used to display the letters, texts, and figures of each item in the status information; and the variable display area B is provided with a plurality of fixed-position segment codes; wherein each sensing signal corresponds to a combination of a plurality of segment codes in different positions, so as to perform picture display of the numbers in the status information in different preset directions.

[0093] The display unit 3 is configured to, when a first sensing signal is detected, perform picture display of the numbers of each item in the status information in a first preset direction at a combination of segment codes corresponding to the first sensing signal; and when a second sensing signal is detected, perform picture display of the numbers of each item in the status information in a second preset direction at a combination of segment codes corresponding to the second sensing signal.

[0094] In the embodiment, the numbers displayed by the display unit 3 can be combined by a plurality of segment codes, so that the display unit 3 can combine segment codes in different positions or areas when displaying horizontally and vertically, so as to display the numbers in the status information of the uninterruptible power supply in different preset directions.

[0095] Here, by configuring the display unit 3, the different sensing signals and the combinations of segment codes in different positions in the variable display area B are matched, so as to realize the transformation of the direction of the numbers in the display unit 3.

[0096] AsFigure 5 In the display unit 3, when the first sensing signal is detected, the middle code combination B1 in the changeable display area B is selected to display the picture of the number. When the second sensing signal is detected, the middle code combination B2 in the changeable display area B is selected to display the picture of the number. In the two kinds of picture display, the picture of the number is in a state of rotation relative to the changeable display area B in the display unit 3.

[0097] In the display unit 3, the positions of the letters, words and graphics in the state information of the uninterruptible power supply can be fixedly displayed, i.e., displayed at fixed positions to indicate different items in the state information.

[0098] In addition, S1, S2, S3 and S4 in the figure represent four corners of the display picture of the display unit, and the relative positions between the four corners and the cabinet body are fixed.

[0099] Optionally, the display unit 3 comprises a plurality of fixed display areas; each fixed display area displays a picture in a different preset direction; and each sensing signal corresponds to a fixed display area.

[0100] When the first sensing signal is detected, the display unit 3 displays the letters, words and graphics of each item in the state information in the first preset direction in the fixed display area corresponding to the first sensing signal. When the second sensing signal is detected, the display unit 3 displays the letters, words and graphics of each item in the state information in the second preset direction in the fixed display area corresponding to the second sensing signal.

[0101] In the embodiment, a plurality of fixed display areas can be arranged in the display unit 3, and the letters, words and graphics of each item in the state information are displayed in different preset directions in each fixed display area, so that the letters, words and graphics in the state information can also be directionally transformed, and the picture display of the letters, words and graphics can also be matched with the installation direction of the cabinet 1.

[0102] Here, by matching different sensing signals and different fixed display areas in the display unit 3, the transformation of the direction of the letters, words and graphics in the display unit 3 is realized.

[0103] As Figure 6 In the display unit 3, when the first sensing signal is detected, the middle code combination B1 in the changeable display area B is selected to display the picture of the number. When the second sensing signal is detected, the middle code combination B2 in the changeable display area B is selected to display the picture of the number. In the two kinds of picture display, the picture of the number is in a state of rotation relative to the changeable display area B in the display unit 3.

[0104] In some embodiments, as Figure 7As shown, the display unit 3 is used to display the status information of the uninterruptible power supply; wherein the status information includes at least one item, and each item includes at least one of numbers, letters, text and graphics.

[0105] Each sensing signal corresponds to a certain item arrangement; where the item arrangement is the arrangement of numbers, letters, text and graphics in each item in different preset directions.

[0106] The display unit 3 is configured to display the screen in the order of items corresponding to the first sensing signal when the first sensing signal is detected, and to display the screen in the order of items corresponding to the second sensing signal when the second sensing signal is detected.

[0107] In this embodiment, the display unit 3 can be configured with a variety of different preset orientations for item arrangement. By configuring the display unit 3, different sensing signals and different item arrangement methods can be matched to realize the change of the orientation of the display screen in the display unit 3.

[0108] like Figure 7 As shown, when display unit 3 detects the first sensing signal, it displays the image in a first item arrangement, wherein the numbers displayed on the screen are parallel to the edge formed by S1 and S2 of the display unit. When display unit 3 detects the second sensing signal, it displays the image in a second item arrangement, wherein the numbers displayed on the screen are parallel to the edge formed by S2 and S3 of the display unit. In both display scenarios, the image displayed by display unit 3 is rotated 90° relative to display unit 3.

[0109] Optionally, the arrangement of each item may differ only in the preset direction, or it may have at least one of the following differences in addition to the preset direction: different arrangement positions of each item, different selection of letters, text and graphics for each item, different types or numbers of items displayed, etc.

[0110] For example, if the screen displaying the image on display unit 3 is rectangular, the length of the image that can be displayed on the same horizontal line on display unit 3 differs between horizontal and vertical display. In horizontal display, two items can be displayed on one horizontal line of display unit 3. In vertical display, two items cannot be displayed simultaneously on one horizontal line of display unit 3; only one item can be displayed, and the other item can be displayed on the next line, i.e., the horizontal line below, to change the arrangement of the items.
