[0064] The present application fixes the wire harness 70 through the wire pressure adjustment device 10, and adjusts the pressure applied to the wire harness 70 by the movable plate 12 and the fixed plate 11, so that the pressure applied to the wire harness 70 by the movable plate 12 and the fixed plate 11 reaches a preset pressure value, so that the wire harness 70 can meet the test requirements after being fixed.

[0065] Combination Figures 1 to 5 As shown, an embodiment of the present disclosure provides a wire pressing adjustment device 10. The wire pressing adjustment device 10 includes a fixed plate 11, a movable plate 12, an adjusting bolt 20 and a driving member 30. The movable plate 12 and the fixed plate 11 are arranged side by side, and the movable plate 12 and the fixed plate 11 define a wire pressing space 13. The adjusting bolt 20 is movably arranged in the movable plate 12 and the fixed plate 11. The driving shaft 31 of the driving member 30 is connected to the adjusting bolt 20. Among them, the driving member 30 is used to drive the adjusting bolt 20 to rotate relative to the movable plate 12 and the fixed plate 11 to adjust the pressure applied by the movable plate 12 and the fixed plate 11 to the wire harness 70 in the wire pressing space 13.

[0066] In this embodiment, the movable plate 12 and the fixed plate 11 are arranged side by side, and the movable plate 12 and the fixed plate 11 define a wire pressing space 13, which can provide an installation space for the wire harness 70 (for example, a power cord), and can fix the wire harness 70 through the cooperation of the movable plate 12 and the fixed plate 11.

[0067] In this embodiment, the adjusting bolt 20 is movably provided in the movable plate 12 and the fixed plate 11, that is, the adjusting bolt 20 can pass through the movable plate 12 and the fixed plate 11, and the adjusting bolt 20 can rotate relative to the movable plate 12 and the fixed plate 11. The driving shaft 31 of the driving member 30 is connected to the adjusting bolt 20, so that the rotation of the driving shaft 31 of the driving member 30 can drive the adjusting bolt 20 to rotate.

[0068] In this embodiment, the driving shaft 31 of the driving member 30 rotates, driving the adjusting bolt 20 to rotate relative to the movable plate 12 and the fixed plate 11, so as to adjust the pressure applied by the movable plate 12 and the fixed plate 11 to the wire harness 70 in the wire pressing space 13, thereby realizing automatic pressure adjustment, making the operation process simple and convenient, and improving work efficiency. Moreover, by automatically adjusting the pressure applied to the wire harness 70, safety can be improved.

[0069] Exemplarily, after the movable plate 12 and the fixed plate 11 pre-fix the wire harness 70 in the wire pressing space 13, the adjusting bolt 20 is driven by the driving member 30 to rotate clockwise relative to the movable plate 12 and the fixed plate 11, so that the pressure applied to the wire harness 70 by the movable plate 12 and the fixed plate 11 can be increased. The adjusting bolt 20 is driven by the driving member 30 to rotate counterclockwise relative to the movable plate 12 and the fixed plate 11, so that the pressure applied to the wire harness 70 by the movable plate 12 and the fixed plate 11 can be reduced.

[0070] Optionally, combined Figure 1 and Figure 2 As shown, there are two adjusting bolts 20. The two adjusting bolts 20 are symmetrically arranged on both sides of the wire pressing space 13 to achieve stable adjustment of the pressure applied to the wire harness 70.

[0071] In some embodiments, in combination Figures 1 to 5 As shown, the adjusting bolt 20 includes a head 21 and a screw portion 22. The head 21 has a mounting cavity 211. The screw portion 22 is connected to the head 21, and the screw portion 22 is provided with a through hole 221 communicating with the mounting cavity 211. The screw portion 22 is inserted through the movable plate 12 and the fixed plate 11. The driving member 30 is provided at the head 21, and the driving member 30 is located in the mounting cavity 211. The driving shaft 31 is inserted through the through hole 221, and the driving shaft 31 cooperates with the screw portion 22. The rotation of the driving shaft 31 of the driving member 30 can drive the screw portion 22 to rotate relative to the movable plate 12 and the fixed plate 11, thereby driving the adjusting bolt 20 to rotate relative to the movable plate 12 and the fixed plate 11.

[0072] In this embodiment, the head 21 has an installation cavity 211, which can provide an installation space for the driver 30. When applied to the outdoor unit 61, the driver 30 is installed inside the head 21, which can reduce the space occupied by the outdoor unit 61, help reduce the overall volume of the outdoor unit 61, and optimize the structure of the outdoor unit 61. In addition, the head 21 can also protect the driver 30 and increase the service life of the driver 30.

[0073] In this embodiment, the screw portion 22 is connected to the head portion 21, that is, the screw portion 22 and the head portion 21 can be connected as a whole, and the rotation of the screw portion 22 can drive the head portion 21 to rotate, thereby realizing the rotation of the entire adjusting bolt 20 relative to the movable plate 12 and the fixed plate 11. The screw portion 22 is provided with a through hole 221 that is connected to the installation cavity 211, so that the driving shaft 31 of the driving member 30 can extend out of the installation cavity 211 and pass through the through hole 221 to cooperate with the screw portion 22, thereby realizing that the rotation of the driving shaft 31 can drive the screw portion 22 to rotate, thereby driving the adjusting bolt 20 to rotate relative to the movable plate 12 and the fixed plate 11.

[0074] In this embodiment, the driving member 30 is arranged on the head 21 and is located in the installation cavity 211. The driving shaft 31 is passed through the through hole 221 and is connected to the screw portion 22, so that the rotation of the driving shaft 31 of the driving member 30 can drive the screw portion 22 to rotate relative to the movable plate 12 and the fixed plate 11, thereby realizing that the adjusting bolt 20 rotates as a whole relative to the movable plate 12 and the fixed plate 11 and moves along the axial direction of the adjusting bolt 20 to adjust the pressure applied by the movable plate 12 and the fixed plate 11 to the wiring harness 70 in the wire pressing space 13.

[0075] Optionally, combined Figure 3 As shown, the head 21 is coaxially arranged with the screw portion 22. A connecting groove 212 is provided in the middle of the head 21 away from the screw portion 22, and the connecting groove 212 is used to connect an external tool.

[0076] In this embodiment, the head 21 is coaxial with the screw portion 22, and the connecting groove 212 is opened in the middle of the head 21, so that the head 21 can be driven to rotate by an external tool (such as a screwdriver), and then the screw portion 22 can be driven to rotate, thereby realizing manual adjustment of the rotation of the screw portion 22.

[0077] Optionally, combined Figure 4 As shown, a plurality of protrusions 213 are arranged circumferentially on the outer surface of the head 21. A recess is formed between two adjacent protrusions 213 to facilitate the staff to hold.

[0078] Optionally, combined Figure 4 As shown, a plurality of protrusions 213 are evenly arranged along the circumference of the head 21 to provide comfort for the staff in holding.

[0079] For example, when pre-fixing the wire harness 70, the staff first holds the outer surface of the head 21 and manually rotates the adjusting bolt 20 to rotate the adjusting bolt 20 relative to the movable plate 12 and the fixed plate 11, so that the movable plate 12 and the fixed plate 11 pre-fix the wire harness 70. When the adjusting bolt 20 needs to be further tightened, the screwdriver can be pressed against the connecting groove 212 to drive the adjusting bolt 20 to rotate, so as to further tighten the wire harness 70.

[0080] In some embodiments, in combination Figure 4 As shown, the adjusting bolt 20 further includes a first matching portion 222. The first matching portion 222 is disposed on the hole wall of the through hole 221 of the screw portion 22. The outer wall of the driving shaft 31 is provided with a second matching portion 311 that matches the first matching portion 222. In the process of the driving shaft 31 rotating, the second matching portion 311 and the first matching portion 222 match to enable the driving shaft 31 to drive the screw portion 22 to rotate.

[0081] In this embodiment, the first matching portion 222 is arranged on the hole wall of the through hole 221 of the screw portion 22, and the outer wall of the driving shaft 31 is provided with a second matching portion 311. The second matching portion 311 and the first matching portion 222 cooperate so that the rotation of the driving shaft 31 can drive the screw portion 22 to rotate.

[0082] Optionally, combined Figure 4 As shown, the first matching portion 222 is a first plane, and the second matching portion 311 is a second plane. The second plane contacts and matches with the first plane, so that the rotation of the driving shaft 31 can drive the screw portion 22 to rotate.

[0083] Optionally, the first matching portion 222 is a limiting groove. The second matching portion 311 is a limiting protrusion 213. The limiting protrusion 213 is slidably matched with the limiting groove. The limiting protrusion 213 and the limiting groove both extend along the axial direction of the screw portion 22. The limiting protrusion 213 and the limiting groove can slide relative to each other, so that the screw portion 22 and the drive shaft 31 are matched and installed. The limiting groove is used to limit the limiting protrusion 213 circumferentially, so that the drive shaft 31 can rotate to drive the screw portion 22 to rotate.

[0104] Combination Figures 1 to 7 As shown, the embodiment of the present disclosure further provides an air conditioner 60. The air conditioner 60 includes an outdoor unit 61 and a wire pressing adjustment device 10 as in any of the previous embodiments. The wire pressing adjustment device 10 is disposed at the outdoor unit 61.

[0105] In this embodiment, the wire pressure adjustment device 10 is arranged on the outdoor unit 61, which can realize automatic adjustment of the pressure applied to the wire harness 70 by the movable plate 12 and the fixed plate 11. The operation process is simple and convenient, which improves work efficiency and safety.

[0106] Optionally, combined Figure 6 and Figure 7 As shown, the outdoor unit 61 includes a mounting plate 611. The wire pressing adjusting device 10 is arranged on the mounting plate 611. In order to realize the installation of the wire pressing adjusting device 10 on the outdoor unit 61.

[0107] For example, the connection nut 50 may be fixed to the mounting plate 611 of the outdoor unit 61 so that the pressure applied to the wiring harness 70 can be adjusted by rotating the adjustment bolt 20 .

[0108] In some embodiments, in combination Figure 6As shown, the air conditioner 60 further includes an indoor unit 62. The indoor unit 62 is connected to the outdoor unit 61. The indoor unit 62 includes a display screen 621. In the case where the wire pressure adjustment device 10 includes a controller, the controller is electrically connected to the display screen 621. The display screen 621 can display the pressure applied to the wire harness 70.

[0109] In this embodiment, the indoor unit 62 is connected to the outdoor unit 61 to achieve normal operation of the air conditioner 60 .

[0110] In this embodiment, the indoor unit 62 includes a display screen 621, and the controller is electrically connected to the display screen 621. After the controller obtains the pressure applied by the movable plate 12 to the wiring harness 70, it can be displayed through the display screen 621 of the indoor unit 62, which is convenient for the installer to observe and improves work efficiency and convenience.

[0111] In actual application, the controller can be electrically connected to the main control board of the indoor unit 62. The main control board of the indoor unit 62 is electrically connected to the display screen 621. So that the display screen 621 can display the pressure applied to the wire harness 70 by the fixed plate 11 and the movable plate 12.

[0112] Optionally, the air conditioner 60 further includes an alarm. The alarm is electrically connected to the signal output terminal of the controller. The controller is used to control the alarm to work according to the pressure applied to the wiring harness 70 by the movable plate 12 and the fixed plate 11.

[0113] Application examples:

[0114] Taking the case where the wire pressure regulating device 10 is disposed in the outdoor unit 61 and the wire harness 70 is a power line (eg, 220V) as an example, the process of regulating the pressure applied to the wire harness 70 by the wire pressure regulating device 10 is described.

[0115] The after-sales installer first pre-fixes the power line. Specifically, the fixed plate 11 and the movable plate 12 clamp the wire harness 70, and tighten the adjustment bolt 20 to achieve the pre-fixation of the fixed plate 11 and the movable plate 12 to the wire harness 70.

[0116] After the outdoor unit 61 is powered, the pressure sensor 14 detects the pressure Y1 applied to the wire harness 70 by the fixed plate 11 and the movable plate 12, and sends the pressure to the controller.

[0117] When Y1 is greater than or equal to Y0 (preset pressure value), the display screen 621 of the indoor unit 62 displays the pressure value applied to the harness 70, and the installation and fixing work of the harness 70 is completed. In other words, the pressure applied to the harness 70 reaches the preset pressure, which enables the indoor unit 62 to operate normally.

[0118] When Y1 is less than Y0 (preset pressure value), the controller controls the alarm to sound an alarm (e.g., a buzzer). The display screen 621 of the indoor unit 62 can display the pressure value applied to the wiring harness 70, which is convenient for after-sales installers to view. At the same time, the controller controls the driver 30 to start, and the driver 30 drives the adjustment bolt 20 to rotate relative to the movable plate 12 and the fixed plate 11 (in a preset direction) to increase the pressure applied to the wiring harness 70. Until Y1 is greater than or equal to Y0, the controller controls the alarm to stop the alarm and controls the driver 30 to stop working. Automatic adjustment of the pressure applied to the power cord is achieved, the operation process is simple and convenient, work efficiency is improved, and safety is improved.

[0119] It should be noted that, in actual application, the display screen 621 can also be used to display fault codes. For example, when the controller controls the alarm to sound an alarm, a fault code (for example, 011) can be displayed on the display screen 621, indicating that the indoor unit 62 cannot operate normally because the pressure applied to the wiring harness 70 is less than the preset pressure, so that the installer can quickly know the fault type and improve work efficiency.
