Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a chassis assembly, a parking air conditioner, a control method, and a vehicle. Background Technology

[0002] In related technologies, roof-mounted parking air conditioners widely employ a method of attaching a rubber sealing strip between the air conditioner chassis and the sunroof, and then tightening and compressing the rubber sealing strip with bolts to achieve a sealing effect. Because the chassis width is greater than the sunroof width, a portion of the bottom area will be suspended in the air. This suspended area is prone to vibration and deformation during driving. Furthermore, the current use of lightweight plastic materials for the parking air conditioner chassis increases the risk of chassis deformation, which can severely damage critical internal components of the parking air conditioner, thereby reducing its reliability. Summary of the Invention

[0003] To overcome the problem in related technologies where a parking air conditioner placed on a sunroof causes deformation in parts of the chassis due to its suspended installation, this invention proposes a chassis assembly for use with a parking air conditioner. The chassis assembly includes:

[0019] If the distance is less than a preset distance, the telescopic component of the deformation correction device is controlled to move towards the roof of the vehicle.

[0020] In some embodiments, the control method includes, when the distance is less than a preset distance, first controlling the telescopic component of the deformation correction device to move away from the chassis to a reset position, and then controlling the telescopic component to move towards the chassis to a target position.

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0035] The following detailed description of the implementation methods is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following implementation methods and examples can be combined with each other.

[0036] According to an exemplary embodiment, such as Figures 1-3 As shown, this embodiment proposes a chassis assembly for a parking air conditioner. The chassis assembly includes a chassis 1. When the parking air conditioner is installed in the vehicle, the chassis 1 is mounted on the vehicle roof 7 and corresponds to the sunroof 16. The chassis assembly also includes a deformation detection device 6, which is used to detect the deformation state of the chassis 1. In one example (not shown in the example figure), the deformation detection device 6 is an angle detection device. When the parking air conditioner is installed in the vehicle, the angle detection device determines the deformation state of the chassis 1 by detecting the angle between the chassis 1 and the horizontal plane. When the angle between the chassis 1 and the horizontal plane is greater than a preset angle, it is determined that the chassis 1 is in a deformation state that needs to be corrected. In another example, refer to... Figure 2 The deformation detection device 6 is an infrared ranging sensor, which is located on the back side 101 of the chassis 1, which is the side opposite to the roof 7. When the parking air conditioner is installed in the vehicle, the infrared ranging sensor detects the distance between a preset position of the chassis 1 and the roof 7; the preset position is the position set by the infrared ranging sensor. The parking air conditioner can determine the deformation state of the chassis 1 based on the distance information detected by the infrared ranging sensor. In one example, the back side 101 of the chassis 1 has a mounting slot 14, and the infrared ranging sensor is installed in the mounting slot 14. The chassis assembly also includes a deformation correction device, which is located on the chassis 1. The deformation correction device is controlled to generate a reaction force on the chassis 1 according to the degree of deformation of the chassis 1. Under the reaction force, the chassis 1 can return to its initial position before deformation. Since the length of chassis 1 is greater than the width of sunroof 16 when it is installed on the vehicle's sunroof 16, a portion of chassis 1 will be suspended in the air. Both the deformation detection device 6 and the deformation correction device are located in the suspended area of ​​chassis 1. When the deformation detection device 6 detects deformation of chassis 1, the distance between the suspended portion and the vehicle decreases. The deformation correction mechanism then corrects the suspended portion in a direction away from the roof 7, restoring it to its pre-deformation state, thereby ensuring the reliability of the parking air conditioner.

[0037] In some embodiments, the deformation detection device 6 and the deformation correction device are arranged opposite to each other along the centerline of the chassis 1 so that the deformation correction mechanism can be adjusted according to the deformation state of the location of the deformation detection device 6.

[0038] In other possible implementations, the chassis assembly includes multiple deformation detection devices 6 and multiple deformation correction devices, with each deformation detection device 6 and deformation correction device corresponding to the other. The multiple deformation detection devices 6 are arranged along the length and / or width of the chassis 1, and the deformation detection devices 6 and the corresponding deformation correction devices are arranged opposite each other along the length or width of the chassis 1, so that deformation at different positions of the chassis 1 can be corrected.

[0039] In some embodiments, such as Figure 1 As shown, the chassis 1 includes a rear end portion 15. When the chassis 1 is engaged with the sunroof 16 of the vehicle, the rear end portion 15 is suspended above the sunroof 16. Both the deformation detection device 6 and the deformation correction device are located on the rear end portion 15. Since the rear end portion 15 is suspended relative to the roof 7, under the weight of the components inside the parking air conditioner housing, the rear end portion 15 generally bends downwards and deforms. After deformation, the distance between the rear end portion 15 and the roof 7 decreases. The deformation detection device 6 detects the degree of deformation of the rear end portion 15, and the deformation correction device is controlled to generate a reaction force on the rear end portion 15 according to the degree of deformation. Under this reaction force, the rear end portion 15 can return to its initial position before deformation.

[0040] In some embodiments (not shown in the figures), the deformation correction device includes a deformation section made of piezoelectric material. The deformation section is located in the area of ​​the sunroof 16 that is suspended above the chassis 1 when the chassis 1 is assembled with the sunroof 16. When the deformation detection device 6 detects that the chassis 1 is in a deformed state, the deformation section is energized to deform it away from the roof 7, thereby correcting the suspended portion. The magnitude of the current flowing through the deformation section can be determined based on the degree of deformation of the chassis 1; the greater the degree of deformation of the chassis 1, the greater the current flowing through the deformation section. The degree of deformation of the chassis 1 can be determined based on the distance or angle data detected by the deformation detection device 6; the smaller the distance data detected by the deformation detection device 6 or the larger the angle data detected, the greater the degree of deformation of the chassis 1.

[0041] In some embodiments, the deformation correction device includes a drive component 3 and a telescopic component. The drive component 3 is connected to the telescopic component and can drive the telescopic component to move on the back side 101 of the chassis 1 in a direction perpendicular to the chassis 1. In one example (not shown in the example figure), the drive component 3 includes a drive motor, and the telescopic component includes a telescopic push rod. The drive motor is located on the inner side 102 of the chassis 1, which is the side located inside the housing of the parking air conditioner. The inner side 102 is opposite to the back side 101. A through hole is provided on the chassis 1 at the position corresponding to the drive motor. One end of the push rod is connected to the drive motor, and the other end extends out of the chassis 1 through the through hole. When the chassis 1 is in a deformed state, the drive mechanism drives the push rod to stretch towards the roof 7 until the deformed part of the chassis 1 returns to its pre-deformation state.

[0042] In another example, such as Figures 1-3 As shown, the drive component 3 includes a drive motor, such as a stepper motor, which is located on the inner side 102 of the chassis 1. A through hole (not shown) is provided on the chassis 1 at a position corresponding to the drive motor. The telescopic component includes a ball screw, which includes a screw 11 and a nut 12. One end of the screw 11 is connected to the drive motor, and the other end extends out of the chassis 1 through the through hole. The nut 12 is located at the end of the screw 11 furthest from the drive motor and can move axially along the screw 11. When the chassis 1 is in a deformed state, the drive mechanism drives the screw 11 to rotate. Under the action of the balls, the screw 11 moves towards the roof 7 until the deformed portion of the chassis 1 returns to its pre-deformation state. For example, as shown... Figures 1-3 As shown, the deformation correction mechanism also includes a support component 4, which is located on the side of the nut 12 away from the drive motor. The nut 12 can drive the support component 4 to move along the axial direction of the screw 11, so that the chassis 1 can recover its deformation by abutting against the roof 7 through the support component 4. In this embodiment, by setting the support component 4, it is ensured that the nut 12 can provide axial support force to the chassis 1 through the roof 7 during the axial movement along the screw 11. The deformed part of the chassis 1 can deform in a direction away from the roof 7, thereby restoring the deformed part to its state before deformation.

[0043] In some implementations, such as Figure 3As shown, the support component 4 includes a support column, with one end of the nut 12 facing the support column and a first protrusion 121. The internal thread of the nut 12 extends into the interior of the first protrusion 121. A mounting hole 41 is provided on the support column at a position corresponding to the first protrusion 121, and the first protrusion 121 mates with the mounting hole 41. In this embodiment, by providing the first protrusion 121 and having the internal thread of the nut 12 extend into the interior of the first protrusion 121, the stroke of the nut 12 along the screw 11 is increased. This ensures that the distance the nut 12 moves along the screw 11 towards the roof 7 is sufficient for the support column to abut against the roof 7. At the same time, the first protrusion 121 mates with the mounting hole 41 of the support column. The nut 12 and the support column are further fixedly connected by screws, ensuring the reliability of the assembly between the nut 12 and the support column.

[0044] In some implementations, such as Figures 1-3 As shown, the telescopic component also includes a foot pad 5, which is disposed on the side of the support column opposite to the nut 12. After the deformation correction mechanism corrects the chassis 1, the foot pad 5 abuts against the roof 7. The foot pad 5 is, for example, a rubber foot pad 5. The foot pad 5 can be disposed on the support column by means of snap-fit, adhesive, or connector. In one example, such as... Figure 3 As shown, the mounting hole 41 is a through hole, and a second protrusion 51 is provided on the side of the foot pad 5 near the support column. The second protrusion 51 is interference-fitted with the mounting hole 41. In this embodiment, the foot pad 5 is provided to provide shock absorption and cushioning for the chassis 1.

[0045] In some embodiments, the chassis assembly includes a reinforcing plate 8, and a groove 13 is provided on the back side 101 of the chassis 1 along the width direction of the chassis 1. The reinforcing plate 8 is disposed within the groove 13, and a deformation correction mechanism is disposed on the reinforcing plate 8. In one example, the reinforcing plate 8 includes a sheet metal part extending along the width direction of the chassis 1. Disposing the reinforcing plate 8 within the groove 13 can ensure increased strength in the width direction of the chassis 1 while avoiding increasing the thickness of the chassis 1, which would affect the deformation correction effect.

[0046] According to an exemplary embodiment, this embodiment provides a parking air conditioner, which includes the chassis assembly proposed in any of the above embodiments.

[0047] According to an exemplary embodiment, this embodiment proposes a control method for a parking air conditioner. The control method is used to control the parking air conditioner proposed in the above embodiment. Figure 5 This is a control flowchart of a parking air conditioner according to an exemplary embodiment, with reference to... Figure 5 The control method includes: obtaining the distance between the preset position of the rear end 15 of the chassis 1 and the roof 7, and controlling the telescopic component of the deformation correction device to move towards the roof 7 when the distance is less than the preset distance.

[0048] In this embodiment, refer to Figure 5 The control panel of the parking air conditioner is equipped with a correction initialization button and a correction command button. In the control method of this embodiment, the command to collect instruction information from the air conditioner control panel is first executed, and the currently collected instruction information is judged. When a correction initialization command is detected, a correction initialization operation is triggered; when a correction command is detected, a correction operation is triggered. The correction initialization command controls the infrared ranging sensor to collect the distance data from the preset position of the rear end 15 of the parking air conditioner chassis 1 to the upper surface of the roof 7, and sets this distance data as the preset distance before the chassis 1 is deformed, and stores it in the parking air conditioner master controller. The correction command first controls the infrared ranging sensor to collect the distance data from the preset position of the rear end 15 of the parking air conditioning chassis 1 to the roof 7, and compares this distance data with the preset distance stored in the controller to evaluate the degree of deformation of the rear end 15 of the parking air conditioning chassis 1. When the deformation exceeds the preset correction threshold, that is, when the distance between the preset position of the rear end 15 of the chassis 1 and the roof 7 is greater than the preset distance, the parking air conditioning main controller will issue a correction command to the telescopic component of the deformation correction device.

[0049] Upon receiving the correction command, the parking air conditioning master controller automatically calculates the distance that the telescopic component of the deformation correction device needs to descend relative to the roof 7, and sends the relevant data to the controller of the drive component 3. Under the control of the controller of the drive component 3, the drive component 3 drives the telescopic component to move towards the roof 7 and make contact with and press against the roof 7. After the telescopic component descends to the target position where the tail end 15 returns to its deformation, the drive component 3 stops. Under the action of the chassis 1 reinforcing plate 8, the tail end 15 bends away from the roof 7 to the initial position of the chassis 1, thus completing the correction of the chassis 1 deformation.

[0050] In some embodiments, the control method includes, when the distance is less than a preset distance, first controlling the telescopic component of the deformation correction device to move away from the chassis 1 to the reset position, and then controlling the telescopic component to move towards the chassis 1 to the target position.

[0051] In this embodiment, considering that the deformation of the chassis 1 is a small distance, when the driving component 3 uses a stepper motor and the telescopic component includes a ball screw, since the stepper motor drives the ball screw to translate a limited distance, the nut 12 needs to be reset before correcting the deformation state of the tail end 15 so that the stepper motor can drive a longer distance. The reset position of the nut 12 is set by the controller before leaving the factory. For example, the reset position is set at a position 5mm away from the lower end face of the stepper motor. The stepper motor can drive the screw 11 to rotate coaxially. After receiving the correction command, the stepper motor drives the screw 11 to reverse, and the stepper motor drives the nut 12 and the support column to move towards the chassis 1 for reset. Then, according to the correction information transmitted by the parking air conditioning master controller, that is, the stepper motor drives the screw 11 to rotate forward, forcing the nut 12 and the support column to move towards the roof 7 and make contact compression until it descends to the target position that can restore the deformation of the tail end 15.

[0052] According to an exemplary embodiment, such as Figure 4 As shown, this embodiment proposes a vehicle including a roof 7 with a sunroof 16. A sealing ring 2, such as a rubber sealing ring 2, is provided around the sunroof. The vehicle also includes a parking air conditioner as described in the previous embodiment, located outside the roof 7 and corresponding to the sunroof 16. A chassis 1 is mounted on the sealing ring 2, which seals the parking air conditioner chassis 1 and the sunroof 16. The rear end 15 of the chassis 1 is suspended above the sunroof 16. A deformation detection device 6 and a deformation correction device are both located at the rear end 15. The deformation detection device 6 detects the distance between the rear end 15 and the roof 7, and the deformation correction device corrects the deformation state of the rear end 15 based on the detected distance data. This embodiment can automatically correct the deformation state of the rear end 15, thereby ensuring the reliability of the parking air conditioner.
