[0006] The anti-falling assembly (4) further comprises a connecting card seat fixed on the side wall of the air conditioner outdoor unit body (1), and a driving member fixed on the wall surface corresponding to the position of the connecting card seat, wherein the driving member is connected to a chuck (45), and the chuck (45) can be driven by the driving member to move horizontally and linearly toward the connecting card seat until it is engaged in the connecting card seat.

[0007] It also includes a controller, the pressure sensor is electrically connected to the controller for signal transmission, and the controller is electrically connected to the driving member in the anti-fall component (4).

[0008] Furthermore, the monitoring assembly (3) further comprises a first screw rod (31) and a slider, wherein the first screw rod (31) is mounted on the side wall of the air conditioner outdoor unit body (1) in a vertically rotatable manner, and the slider is mounted on the side wall of the air conditioner outdoor unit body (1) in a vertically slidable manner and is screwed onto the first screw rod (31), wherein the slider and the first screw rod (31) form a vertical first screw rod slider mechanism, and the monitoring box (33) is fixedly connected to the slider.

[0009] Furthermore, in the monitoring assembly (3), a spring (38) is provided in each through slot (39) at the bottom of the monitoring box (33), and the spring (38) is sleeved on the corresponding probe (34). One end of the spring (38) is fixed to the bottom of the monitoring box (33), and the other end of the spring (38) is fixed to the corresponding probe (34).

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-6 As shown, this embodiment discloses an anti-dropout air conditioner outdoor unit, comprising an air conditioner outdoor unit body 1. Several fixing plates 2 are fixedly connected to the bottom of the four side walls of the air conditioner outdoor unit body 1. Each fixing plate 2 is bolted to a fixing bracket on the exterior wall, thereby securing the air conditioner outdoor unit body 1 to the fixing bracket. A monitoring component 3 is provided on the air conditioner outdoor unit body 1 at a position corresponding to each fixing plate 2.

[0025] Specifically, such as Figure 2As shown, the monitoring assembly 3 includes a first screw rod 31, a slider, and a monitoring box 33. A vertical slot is provided on the side wall of the air conditioner outdoor unit body 1, corresponding to a position above each fixed plate 2. The first screw rod 31 is vertically rotatably mounted within the slot, with a knob 32 fixed to its upper end. The slider is vertically slidably mounted within the slot and is screwed onto the first screw rod 31 via a threaded through-hole. The first screw rod 31 and the slider constitute a first screw-slider mechanism. The monitoring box 33 is fixed to the slider and suspended above the corresponding fixed plate 2.

[0026] like Figure 3 、 Figure 4 As shown, a mounting plate 37 is fixedly mounted on the bottom of the monitoring box 33 via a through-hole. The mounting plate 37 has several vertical through-slots 39 extending therethrough. These through-slots 39 are arranged in a circular array, and a probe 34 is movably mounted in each through-slot 39. The upper ends of the probes 34 are positioned within the monitoring box 33, while the lower ends of the probes 34 are positioned below the monitoring box 33. Several connecting blocks 36 are fixed to the mounting plate 37. A pressure sensor 35 is housed within the monitoring box 33. The connecting blocks 36 on the mounting plate 37 are connected to the bottom of the pressure sensor 35. The center area of the bottom of the pressure sensor 35 serves as the pressure-sensitive surface. The upper ends of the probes 34 point toward the pressure-sensitive surface at the bottom of the pressure sensor 35, while the lower ends of the probes 34 face the tops of the corresponding bolts in the fixing plate 2. By turning the knob 32 to rotate the first screw 31, the vertical position of the monitoring box 33 can be adjusted, thereby adjusting the distance between the lower ends of the probes 34 and the tops of the corresponding bolts in the fixing plate 2, or causing the lower ends of the probes 34 to contact the tops of the corresponding bolts in the fixing plate 2.

[0027] When the bolts between the mounting plate 2 and the mounting bracket become loose, vibrations are generated during operation of the air conditioner outdoor unit 1. This vibration is transmitted to the bolts, causing them to move upward until they contact the lower end of the probe 34 in the corresponding monitoring assembly 3, thereby applying force to the probe 34, causing it to move upward. When the probe 34 moves upward until it contacts the pressure-sensitive surface at the bottom of the pressure sensor 35, the pressure sensor 35 generates a signal, and the probe 34 then falls under its own weight.

[0028] As an improvement to the utility model, Figure 4 As shown, in this embodiment, a spring 38 is disposed within each through-slot 39 of the mounting plate 37 at the bottom of the monitoring box 33. The spring 38 is positioned over the corresponding probe 34, with the upper end of the spring 38 secured to the top surface of the mounting plate 37 and the lower end of the spring 38 secured to the corresponding probe 34. The spring 38 secures the probe 34 within the through-slot 39, and after upward movement, the elastic deformation of the spring 38 allows the probe 34 to quickly return to its original position. Therefore, the spring 38 allows the probe 34 to vibrate up and down when the bolt is loosened.

[0029] This embodiment also includes an anti-falling component 4, which includes a connecting card seat, a driving member, and a chuck 45, wherein the connecting card seat is fixed on the side wall of the air-conditioning outdoor unit body 1, and the driving member is fixed on the outer wall surface where the air-conditioning outdoor unit body 1 is located corresponding to the position of the connecting card seat, and the chuck 45 is driven by the driving member.

[0030] Specifically, such as Figure 5 As shown, the driving member includes a second screw slider mechanism driven by a motor, wherein the base 41 in the second screw slider mechanism is fixed horizontally on the wall, and the second screw rod 42 in the second screw slider mechanism is installed in the base 41 in a horizontally rotatable manner, with one end of the second screw rod 42 pointing to the connecting seat on the air conditioner outdoor unit body 1. The motor is installed on the base 41 and is transmission-connected to the other end of the second screw rod 42, and the second screw rod 42 is driven by the motor to rotate. The slider 43 in the second screw slider mechanism is installed horizontally on the second screw rod 42 and is screwed to the second screw rod 42 through a threaded through hole. The chuck 45 is fixedly connected to the side of the slider 43 in the second screw slider mechanism facing the connecting seat through a connecting rod 44. Therefore, when the motor drives the second screw rod 42 to rotate, the slider 43, the connecting rod 44, and the chuck 45 as a whole make horizontal linear motion toward the connecting seat on the air conditioner outdoor unit body 1.

[0031] like Figure 6 As shown, the connection base includes a clamping base 46 fixed to the side wall of the air conditioner outdoor unit body 1. The clamping base 46 is connected to the upper and lower opposite fixed side plates 41 on the side facing the drive member. A baffle 411 is fixed to the end of each fixed side plate 47 facing the side of the other fixed plate, forming a clamping gap between the two baffles 411. A movable plate 410 is flipped and mounted adjacent to the baffle 411 on the side of each fixed side plate 47 facing the other fixed plate via a hinge 48. Each movable plate 410 is limited by the adjacent baffle 411 and can only flip away from the baffle 411. A connecting spring 49 is connected between the movable plate 410 and the corresponding fixed side plate 47.

[0032] In this embodiment, the chuck 45 is driven by the driving member to move horizontally and linearly until it passes through the clamping gap between the two baffles 411, and continues to move horizontally and linearly until it hits the two movable plates 410, causing the two movable plates 410 to flip in the direction away from the adjacent baffles 410, thereby opening the space between the two movable plates 410. As a result, the chuck 4 can continue to move horizontally and linearly until it penetrates between the two fixed side plates, and the chuck is finally fixed and clamped in the connecting socket. At this time, the air conditioner outdoor unit body 1 is connected to the wall through the anti-fall component 4. In addition, after the movable plate 410 flips, the connecting spring 49 is deformed. The deformation force of the connecting spring 49 causes the two movable plates 410 to clamp the connecting rod 44 connected to the chuck 45, thereby improving the connection stability.

[0033] This embodiment also includes a controller 5, which can be a controller provided by the air conditioner, or a controller separately installed on the air conditioner outdoor unit body 1. The pressure sensors 35 in each monitoring component 3 are electrically connected to the controller 5 for signal transmission, and the controller 5 is electrically connected to the motor control of the driving part in the anti-fall component 4. Thus, the controller 5 can control the action of the driving part in the anti-fall component 4 based on the signal of the pressure sensor 35.

[0034] In this embodiment, when the bolts between mounting plate 2 and the mounting bracket become loose, the vibrations generated by the operation of the air conditioner outdoor unit body 1 cause the bolts to vibrate. This upward vibration exerts a certain thrust on probe 34. Since probe 34 is not fixed but rather positioned within slot 39 by spring 38, the bottom of probe 34, when subjected to thrust, moves upward. The upper end of probe 34 is positioned directly below the pressure-sensitive element of pressure sensor 35. As probe 34 moves upward, it applies pressure to the pressure-sensitive surface. Pressure sensor 35 transmits a pressure signal to controller 5, which activates the motor of anti-fall assembly 4. It is important to note that loose bolts may contact probe 34 not only due to vibrations from the air conditioner. Bolts may also contact probe 34 at the point of loosening due to forces acting on them. Alternatively, strong winds, which cause the mounting bracket and air conditioner outdoor unit 1 to shake, may also cause loose bolts to contact probe 34.

[0035] After the motor is started, the second lead screw 42 rotates, causing the slider 43 to move, which in turn drives the connecting rod 44 to move, causing the chuck 45 to move toward the connecting seat on the air-conditioning outdoor unit body 1. It should be noted that the clamping base 46 in the connecting seat is fixed to the wall by bolts, and it is necessary to ensure that the moving plate 410 is on the moving route of the connecting rod 44. When the chuck 45 pushes the moving plate 410, the chuck will enter the space between the moving plate 410 and the clamping base 46. At this time, the motor is turned off, and the moving plate 410 can only rotate inwards but not outwards through the baffle 411 provided. Moreover, as Figure 4 The top diameter of the chuck 46 shown is smaller than the bottom diameter. Therefore, when the chuck 46 enters the space between the movable plate 410 and the clamping base 46, it cannot fall out from the inside, and the lateral movement of the connecting rod 44 is also restricted. If the fixed bracket is stable, if the air-conditioning outdoor unit body 1 falls, it will only cause the air-conditioning outdoor unit 1 to fall off from the fixed bracket, which requires displacement between the air-conditioning outdoor unit body 1 and the fixed bracket. Therefore, the anti-fall component 4 provided in this embodiment can limit the displacement of the air-conditioning outdoor unit body 1 when the bolts are loosened, prevent the vibration amplitude of the air-conditioning outdoor unit body 1 from increasing due to the loosening of one bolt, causing the other bolts to loosen, and also limit the displacement of the air-conditioning outdoor unit body 1 when the bolts fall off.

[0036] It should be noted that in order to prevent the probe 34 from being triggered by strong winds, heavy snow or heavy rain, a protective cover can be set at the lower end of the monitoring box 33, and a cylinder with a diameter larger than the diameter of the mounting plate 37 can be set. The outer surface of the cylinder is provided with a thread 1, and correspondingly, a mounting groove opposite to the cylinder is opened in the monitoring box 33, and the surface of the mounting groove is provided with a thread 2 opposite to the thread 1, so that the cylinder can move up and down in the mounting groove by rotation. After the monitoring component is adjusted, the cylinder is twisted until it covers the bolt and the probe 34.

[0037] In this embodiment, the controller 5 can be an integrated circuit board, which includes a microprocessor, input and output interfaces, and a communication interface. When the pressure sensor 35 transmits the pressure signal to the controller 5, the controller 5 receives the signal, processes the signal, and then transmits the signal to the terminal 6. The terminal 6 can be a signal light (a signal light can be set on the external unit, and whether the bolt is loose can be determined by whether the signal light is on or off).
