[0002] Uninterruptible power supply is an important device that can provide continuous, stable and uninterrupted power supply to critical equipment.

[0003] After searching, the prior art discloses a non-online UPS uninterruptible power supply (publication number: CN216489588U), which includes a wire threading groove on the back of a placement box, a support leg on the lower surface of the placement box, a blocking door hinged on the front of the placement box, a placement plate installed in the placement box, a power supply body on the upper surface of the placement plate, a connecting frame connected to the front side of the upper surface of the placement box, a cooling fan on the upper surface of the connection frame, a connecting plate installed at the bottom end of the movable column, a movable frame slidably connected to the connecting plate, a plug-in frame on the left side of the movable frame, a cushion layer installed on the right side and the left side of the plug-in frame, a support frame installed on the back of the movable frame, a buffer rod installed on the rear side of the lower surface of the placement plate, and a lower pressure piece installed on the bottom end of the buffer rod.

[0004] In the existing technology, the connected wires are mainly limited by squeezing each other by two wheels, which can only suppress the wire jumping but cannot provide radial tensile strength for the wires. Since there are multiple connected wires, the use of multiple sets of wheels for limiting the position limits the internal space of the box, resulting in a messy layout and space that can be optimized.

[0005] To this end, we propose an uninterruptible power supply. Utility Model Content

[0006] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides an uninterruptible power supply.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions, an uninterruptible power supply, comprising:

[0008] A housing, wherein a battery pack is fixedly mounted inside the housing, and a control panel and a circuit board electrically connected to the battery pack are fixedly mounted on the front and rear walls of the housing, respectively;

[0009] A tidying structure is arranged inside the shell for fixing and tidying the wires connected to the battery pack. The tidying structure includes a lower seat, an upper cover and a limit groove. The lower seat is fixedly connected to the shell. A plurality of limit grooves are opened on the top of the lower seat. The wires pass through the limit grooves and form a serpentine bend. An upper cover is arranged above each limit groove and is engaged with the lower seat. The upper cover can cover the limit groove and limit the wires.

[0010] As a preferred embodiment of the present invention, the lower seat is formed into a rectangular block, the limiting groove is a broken line groove, and the depth of the limiting groove is less than the thickness of the lower seat.

[0011] As a preferred embodiment of the present invention, the upper cover forms a block with a C-shaped cross section, the distance between the inner top surface and the inner bottom surface of the upper cover is equal to the thickness of the lower seat, and the bent portion of the window is snapped onto the bottom of the lower seat.

[0012] As a preferred embodiment of the present invention, the tidying structure further includes a window, and a window is provided on each of the two opposite sides of the upper cover, and the wire passes through the window and is led out of the limiting groove.

[0013] As a preferred embodiment of the present invention, the two ends of the limiting groove are respectively located on both sides of the lower seat, and the two windows on both sides of the upper cover respectively correspond to the two ends of the limiting groove.

[0014] As a preferred embodiment of the present invention, the arranging structure further includes a pressing member, which is arranged at the bottom of the upper cover 21 and located within the limiting groove 22 for limiting the position of the wires.

[0015] As a preferred embodiment of the present invention, the pressing member is a protrusion, and several protrusions are fixedly installed on the top of the upper cover. The lower end of the protrusion is located in the limiting groove, and the protrusion can contact the wire and limit the wire. The protrusion and the upper cover are integrally formed, and the lower end of the protrusion forms a spherical surface. The upper end of the protrusion is provided with several annular grooves, and the upper end of the protrusion forms a columnar step through the annular groove.

[0016] As a preferred embodiment of the present invention, the lower pressure member is a deformation seat and a guide column arranged at the bottom of the upper cover. The deformation seat is fixedly connected to the upper cover, and several guide columns are fixedly installed at the bottom of the deformation seat. The wire passes around each guide column in turn and forms a bend.

[0017] As a preferred embodiment of the present invention, the deformation seat is a strip-shaped structure with a broken line in horizontal cross section. The deformation seat and the upper cover are integrally formed. The middle position of the deformation seat is fixedly connected to the upper cover, and a guide column is fixedly installed at each inflection point of the deformation seat.

[0018] The utility model provides an uninterruptible power supply with the following beneficial effects:

[0019] 1. This uninterruptible power supply places one or several wires into a limiting groove. Due to the broken line shape of the limiting groove, the wires will also form a bent snake shape in the limiting groove. The lower seat is made of a material with elastic deformation ability, such as silicone, and cooperates with the clamping of the upper cover and the lower seat to achieve shielding of the limiting groove and limiting of the internal wires. Then, the wires between the control panel and the circuit board and the battery pack can be kept neatly arranged, and there will be no irregularity caused by the disordered distribution of the guides. The layout inside the shell is more streamlined and the structure is simple, which is convenient for later inspection and maintenance. Secondly, the bent shape formed by the wires in the limiting groove can improve the tensile strength of the wire ends and suppress the probability of the wire ends falling off from the terminal.

[0020] 2. This uninterruptible power supply has multiple protrusions on the bottom of the upper cover extending into the limit slot, thereby forming a multi-point downward pressure limit for the wires in the limit slot. With the clamping connection between the upper cover and the lower seat, the wires in the limit slot can form a bending margin to improve the tensile resistance. At the same time, it can also ensure the stability of the wires in the limit slot, which is more conducive to neat wiring.

[0021] 3. This uninterruptible power supply is provided with a wavy deformation seat, and guide posts are provided at the inflection points of the deformation seat. The wires are sequentially passed around each guide post to form a multi-bending margin. Since the middle position of the deformation seat is fixedly installed with the upper cover, when the wire leading out of the limit slot is pulled, the wire applies tension to the guide post, causing the bent portion of the deformation seat to deform and extend, thereby further buffering the pulling force of the wire connection terminal, further improving the stability of the connection between the wire and the terminal, and coping with the stability of the housing when used in complex environments.

[0022] 4. This uninterruptible power supply is equipped with an extendable and deformable deformation seat in conjunction with multiple guide posts. When the wire length needs to be adjusted when the wire in the limit channel is connected to different terminals, the wire is pulled so that the wire pulls the guide post to force the deformation seat to deform and extend, and the guide posts move closer to or away from each other, thereby being able to adjust the length of the wire within a certain range. This facilitates temporary adjustment of the wire length to connect to different terminals, makes assembly and repair more relaxed and convenient, and reduces the installation limitations of the wire length outside the limit channel.

[0032] An uninterruptible power supply, such as Figure 1 and Figure 2 As shown, including:

[0033] The housing 10 has a battery pack 13 fixedly mounted therein, and a control panel 11 and a circuit board 12 electrically connected to the battery pack 13 fixedly mounted on the front and rear walls of the housing 10, respectively;

[0034] like Figure 3 、 Figure 4 and Figure 5 As shown, the tidying structure is arranged inside the shell 10 for fixing and tidying the wires connected to the battery pack 13. The tidying structure includes a lower seat 20, an upper cover 21 and a limiting groove 22. The lower seat 20 is fixedly connected to the shell 10. A plurality of limiting grooves 22 are opened on the top of the lower seat 20. The wires pass through the limiting grooves 22 and form a serpentine bend. An upper cover 21 is provided above each limiting groove 22 and is engaged with the lower seat 20. The upper cover 21 can block the limiting groove 22 and limit the wires. The lower seat 20 forms a rectangular block. The limiting groove 22 is a broken line groove. The depth of the limiting groove 22 is less than the thickness of the lower seat 20. The upper cover 21 forms a block with a C-shaped cross section. The distance between the inner top surface and the inner bottom surface of the upper cover 21 is equal to the thickness of the lower seat 20. The bent portion of the window 24 is engaged with the bottom of the lower seat 20.

[0035] In this solution, there are two organizing structures, which are used to constrain and organize the wires connecting the control panel 11 and the circuit board 12 to the battery pack 13. Since there are several wires, by placing one or several wires into the limit groove 22, due to the broken line shape of the limit groove 22, the wires will also form a bent snake shape in the limit groove 22, and the lower seat 20 is made of a material with elastic deformation ability, such as silicone, and cooperates with the upper cover 21 and the lower seat 20 to achieve shielding of the limit groove 22 and limiting of the internal wires. Then, the wires between the control panel 11 and the battery pack 13 and the circuit board 12 and the battery pack 13 can be kept neatly arranged, and there will be no irregularity caused by the disordered distribution of the guides. The layout inside the shell 10 is more streamlined, which is convenient for later inspection and maintenance. Secondly, the bent shape of the wire formed in the limit groove 22 can improve the tensile strength of the wire end and suppress the probability of the wire end falling off from the terminal.

[0036] like Figure 6 As shown, the organizing structure also includes a window 24, a window 24 is opened on each opposite side of the upper cover 21, and the wire passes through the window 24 and leads out of the limiting groove 22. The two ends of the limiting groove 22 are respectively located on both sides of the lower seat 20, and the two windows 24 on both sides of the upper cover 21 correspond to the two ends of the limiting groove 22 respectively. As an illustration of the above scheme, by setting the window 24, the guide enters the limiting groove 22 from the window 24 on one side of the upper cover 21 and then leads out from the other window 24 to connect with the battery pack 13, which is convenient for threading the wire and avoids the upper cover 21 and the lower seat 20 from being stuck and causing the wire to be unable to be led out from the limiting groove 22.

[0037] Example 1, as Figure 6 As shown, the finishing structure also includes a lower pressing member, which is a protrusion 23. A plurality of protrusions 23 are fixedly installed on the top of the upper cover 21. The lower end of the protrusion 23 is located in the limiting groove 22. The protrusion 23 can resist the wire and limit the wire. The protrusion 23 is integrally formed with the upper cover 21. The lower end of the protrusion 23 forms a spherical surface. The upper end of the protrusion 23 is provided with a plurality of annular grooves. The upper end of the protrusion 23 forms a columnar step through the annular groove.

[0038] In this solution, the upper cover 21 can be made of silicone material, and multiple protrusions 23 at the bottom of the upper cover 21 extend into the limiting groove 22, thereby forming a multi-point downward pressure limit for the wires in the limiting groove 22. The step-shaped protrusions 23 can be better deformed to squeeze the limiting wires, and with the clamping connection between the upper cover 21 and the lower seat 20, the wires located in the limiting groove 22 can form a bending margin to improve the tensile resistance, and at the same time, it can also ensure the stability of the wires in the limiting groove 22, which is more conducive to neat wiring.

[0039] Example 2, as Figure 7As shown, the lower pressing member is a deformation seat 30 and a guide column 31 provided at the bottom of the upper cover 21. The deformation seat 30 is fixedly connected to the upper cover 21. A plurality of guide columns 31 are fixedly installed at the bottom of the deformation seat 30. The wire passes around each guide column 31 in sequence and forms a bend. The deformation seat 30 is a strip-shaped structure with a horizontal cross-section that is a broken line. The deformation seat 30 and the upper cover 21 are integrally formed. The middle position of the deformation seat 30 is fixedly connected to the upper cover 21. A guide column 31 is fixedly installed at each inflection point of the deformation seat 30.

[0040] In the present solution, as an optimization and improvement of Example 1, the deformation seat 30 is made of silicone material, and the guide column 31 is made of plastic material. By setting a wavy deformation seat 30 and setting a guide column 31 at the inflection point of the deformation seat 30, the wire passes around each guide column 31 in turn to form a multi-bending margin. Since the middle position of the deformation seat 30 and the upper cover 21 are fixedly installed, when the wire leading out of the limit slot 22 is pulled, the wire applies a pulling force to the guide column 31, causing the bent part of the deformation seat 30 to deform and extend, thereby further buffering the pulling force of the wire connection terminal, further improving the stability of the connection between the wire and the terminal, and coping with the stability of the shell when used in a complex environment.

[0041] Further explanation, by setting an expandable and deformable deformation seat 30 in conjunction with multiple guide pillars 31, when the wire length needs to be adjusted when the wire in the limit channel is adjusted to connect with different terminals, the wire is pulled so that the wire pulls the guide pillar 31 to force the deformation seat 30 to deform and extend, and each guide pillar 31 moves closer to or away from each other, thereby being able to adjust the length of the wire within a certain range, making it convenient to temporarily adjust the length of the wire to connect different terminals, making assembly and repair more relaxed and convenient, and reducing the limitations of the length of the wire outside the limit slot 22 on installation.

[0042] The structure inside the housing 10 is as follows Figure 8 As shown in the figure, the battery pack 13 is electrically connected to the control panel 11 and the circuit board 12 respectively. The control panel 11 is connected to the battery pack 13 for signals via wires, and the circuit board 12 is connected to the battery pack 13 for electrical signals via wires. The control panel 11, the circuit board 12 and the battery pack 13 all have wiring terminals, and the wires are welded to the wiring terminals.

[0043] The working principle of this utility model:

[0044] Battery Pack 13

[0045] It is composed of 8 3.7V 50Ah ternary lithium batteries connected in series (nominal 29.6V)

[0046] Positive and negative poles pass through 25mm 2 The copper busbar is connected to the power interface of the circuit board 12

[0047] Control Panel 11

[0048] Contains STM32F407 main control chip + 4.3-inch LCD touch screen

[0049] Connect the communication interface (CAN bus) of circuit board 12 through FPC cable

[0050] Circuit board 12

[0051] Integrate three major modules:

[0052] Charging module: TI BQ24650 chip (supports 0-30V wide voltage input)

[0053] Inverter module: Infineon IGBT FF300R12KT4 (output 220V / 50Hz)

[0054] BMS management: NXP MC33771 battery monitoring IC, due to the mature existing technology, we will not go into details here;

[0055] Put one or several wires into the limiting groove 22. Due to the broken line shape of the limiting groove 22, the wires will also form a bent snake shape in the limiting groove 22. The lower seat 20 is made of a material with elastic deformation ability, such as silicone, and cooperates with the clamping connection between the upper cover 21 and the lower seat 20 to achieve shielding of the limiting groove 22 and limiting of the internal wires. Then, the wires located between the control panel 11 and the battery pack 13 and between the circuit board 12 and the battery pack 13 can be kept neatly arranged. The multiple protrusions 23 at the bottom of the upper cover 21 extend into the limiting groove 22, thereby forming a multi-point downward pressure limit for the wires in the limiting groove 22, and cooperates with the clamping connection between the upper cover 21 and the lower seat 20. The wire located in the limiting groove 22 can form a bending margin to improve the tensile resistance, thereby achieving the limitation and fixation of the wire. Alternatively, a wavy deformation seat 30 is provided, and a guide post 31 is provided at the inflection point of the deformation seat 30. The wire passes around each guide post 31 in turn to form a multi-bending margin. Since the middle position of the deformation seat 30 is fixedly installed with the upper cover 21, when the wire leading out of the limiting groove 22 is pulled, the guide post 31 is pulled by the wire, causing the bent portion of the deformation seat 30 to deform and extend, thereby further buffering the pulling force of the wire connection terminal and adjusting the length of the wire extending outside the limiting groove 22 within a certain range.

[0056] It should be noted that the lower seat 20 is fixed to the inner wall of the shell 10 by a bracket. There is enough space between the lower seat 20 and the inner wall of the shell 10 for the installation of the wires and the clamping of the upper cover 21. The side wall of 10 is provided with a window for installing the circuit board 12 and the control panel 11. The wires are connected to the terminals of the circuit board 12, and the terminals are located in the window. The wires enter the limiting groove 22 and are sorted and limited. Since the circuit board 12 has multiple interfaces, the wires of multiple terminals corresponding to multiple interfaces form a root bus. The bus can be placed in the limiting groove 22 to achieve sorting and limiting. Two groups of sorting structures are set on both sides of the inner wall of the shell 10, which are respectively used to limit the control panel 11 and the wires connecting the circuit board 12 to the battery pack 13. Due to the perspective problem, only the sorting structure on one side of the inner wall of the shell 10 can be shown in the figure.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
