The air conditioning box is prone to produce different noise problems under different working conditions, affecting the driving of the driver and the comfort of the passengers in the vehicle. The noise problems caused by the use of the air conditioning box need to be further improved.

[0003] At present, in order to solve the problem of noise in the air conditioner box, some air conditioning systems are equipped with mufflers to eliminate noise, but the muffler can only eliminate noise of some frequencies, and there is still a problem that the noise cannot be completely eliminated, especially the elimination of the roar requires a muffler of appropriate size. In addition, the space in the passenger compartment is limited, which is not suitable for arranging more mufflers. Utility Model Content

[0004] The present application provides an air-conditioning box and a means of transportation. By arranging adjusting parts and partitions, the volume of the cavity inside the air-conditioning box divided by the partition can be adjusted according to different working conditions, which can avoid Helmholtz resonance when air flows through the cavity, thereby avoiding the roaring sound during the operation of the air-conditioning box at the source.

[0005] In a first aspect, the present application provides an air-conditioning box, comprising a shell, a partition and an adjusting member, wherein the partition is located inside the shell, and the partition divides the interior of the shell into at least two cavities; the partition is mounted on the adjusting member, and the adjusting member is mounted inside the shell, and the adjusting member is used to adjust the relative position of the partition and the shell to adjust the volume of the cavity.

[0006] The cavity has a Helmholtz resonance frequency. Cavities of different sizes have different Helmholtz resonance frequencies. When the air conditioning box is working, the airflow generates vortex shedding at the leading edge of the opening of the cavity. The vortex shedding will impact the trailing edge of the cavity opening at a certain frequency. The frequency of vortex shedding is called the self-excited oscillation frequency. When the self-excited oscillation frequency of vortex shedding is close to or consistent with the Helmholtz resonance frequency of the cavity, a roaring sound will be generated. The air conditioning box provided in the present application is based on the Helmholtz resonance principle. By setting adjustment parts and partitions, the volume of the cavity separated by the partition inside the air conditioning box can be adjusted according to different working conditions of the air conditioning box, so that the Helmholtz resonance frequency of the cavity and the self-excited oscillation frequency of the airflow maintain an unequal relationship, avoiding resonance when the airflow flows through the cavity, thereby avoiding the roaring sound during the operation of the air conditioning box at the source.

[0007] In a possible implementation, the adjusting member includes a driving device, and the driving device is used to drive the partition to move relative to the shell. The driving device can achieve movement of the partition inside the shell by driving the partition to move relative to the shell, change the volume of the cavity, and avoid generating a roaring sound.

[0008] In a possible implementation, the adjusting member further includes a guide member, the guide member is connected to the partition, and the partition is used to move along the guide direction of the guide member. The guide member may have transmission and guiding functions, and the partition may move on the guide member along the guide direction of the guide member, or the guide member drives the partition to move along the guide direction of the guide member, so as to adjust the volume of the cavity.

[0009] In a possible implementation, the guide member includes a lead screw, a threaded hole is provided on the partition, the threaded hole is threadedly connected to the lead screw, and the driving device is used to drive the lead screw to rotate. The partition can be fixed on the lead screw through the threaded hole, and the lead screw moves relative to the housing and drives the partition to move relative to the housing, thereby changing the volume of the cavity.

[0010] In a possible implementation, the number of the partitions is at least two, and the at least two partitions are arranged along the thickness direction of the partition. Multiple partitions are arranged along the thickness direction of the partition, and the multiple partitions can be arranged at intervals or in contact with each other. The multiple partitions can be moved along the thickness direction of the partition, so that the cavities separated by the multiple partitions can be better connected with the air outlet and the air inlet.

[0011] In a possible implementation, there is at least one partition, and each partition is connected to at least one adjusting member. Each partition is connected to an adjusting member, and the position of the partition inside the shell and the spacing between different partitions can be accurately controlled by the adjusting member, so that the volume of the cavity can be better adjusted according to different working conditions of the air conditioner to avoid the generation of roaring sound.

[0012] In a possible implementation, the thickness of the partition is in the range of 1 mm to 2 mm, so that the partition is arranged inside the shell without occupying too much internal space, thereby reducing the layout pressure of the air-conditioning box in the transportation vehicle.

[0013] In a possible implementation, the outer edge of the partition has an elastic structure, the elastic structure abuts against the inner wall of the shell, and the elastic structure covers the outer edge of the partition. The elastic structure is located between the outer edge of the partition and the inner wall of the shell, ensuring that the partition can fit the inner wall of the shell and flexibly adapt to the structure of the inner wall of the cavity as the partition moves relative to the cavity.

[0014] In a possible implementation, the air conditioning box includes a control system, and the control system is electrically connected to the drive device.

[0032] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0033] The present application provides an air conditioning box 100, see Figures 1 to 3 As shown, the air conditioning box 100 includes a housing 110, a partition 120 and an adjustment member 130. The housing 110 includes an air inlet 111 and an air outlet 112. The air inlet 111, the internal space of the housing 110 and the air outlet 112 together enclose a cavity 113. The cavity 113 has a Helmholtz resonance frequency f1. Cavities 113 of different sizes have different Helmholtz resonance frequencies f1.

[0034] The partition 120 is located in the housing 110. The partition 120 divides the interior of the housing 110 into at least two cavities 114. The cavities 114 can be connected to the air inlet 111 and the air outlet 112 to form an air duct to ensure airflow. The partition 120 divides the cavity 113 into at least two cavities 114. At least two cavities 114 have a Helmholtz resonance frequency f1. The Helmholtz resonance frequencies f1 of different cavities 114 can be equal or unequal. In addition, the partition 120 can guide the airflow, so that the airflow flows regularly and improves the flow performance.

[0035] The partition 120 is mounted on the adjusting member 130, and the adjusting member 130 is mounted in the housing 110. The adjusting member 130 is used to adjust the relative position of the partition 120 and the housing 110 to adjust the volume of the cavity 114. The partition 120 moves relative to the housing 110 through the adjusting member 130. The partition 120 can move relative to the housing 110, that is, the volumes of at least two cavities 114 formed by the partition 120 dividing the interior of the housing 110 are adjustable, and the Helmholtz resonance frequencies f1 of the at least two cavities 114 can also change accordingly with the volumes of the cavities 114.

[0036] For example, in one embodiment, the housing 110 has five partitions 120 inside, and the partitions 120 divide the housing 110 into six cavities 114. The partitions 120 are mounted on the adjustment member 130, and the partitions 120 can be moved relative to the housing 110 along the Figure 2 The partition 120 can move in the X direction or the reverse direction of X relative to the housing 110, that is, the adjustment member 130 is installed inside the housing 110 and fixed inside the housing 110, and does not move relative to the housing 110. The partition 120 is installed on the adjustment member 130, and the partition 120 can move in the X direction or the reverse direction of X on the adjustment member 130, so that the partition 120 moves relative to the housing 110. When the partition 120 moves, the volumes of the two cavities 114 change with the movement of the partition 120, and the Helmholtz resonance frequencies f1 of the two cavities 114 can also change.

[0037] In one embodiment, the partition 120 can move relative to the housing 110 in the X direction or the opposite direction of X, that is, the adjustment member 130 is installed inside the housing 110, the adjustment member 130 is not fixed inside the housing 110, the adjustment member 130 can move relative to the housing 110, the partition 120 is installed on the adjustment member 130, the adjustment member 130 can move relative to the housing 110 and drive the partition 120 to move relative to the housing 110 in the X direction or the opposite direction of X. When the partition 120 moves, the volumes of the two cavities 114 change with the movement of the partition 120, and the Helmholtz resonance frequencies f1 of the two cavities 114 can also change.

[0038] The Helmholtz resonance principle can be used for sound absorption and sound generation. Both sound absorption and sound generation are closely related to the Helmholtz resonance frequency f1. Fig.9A As shown, Fig.9A Schematic diagram of the Helmholtz resonance sound absorption principle of the cavity 113 or the volume cavity 114. The expression of the Helmholtz resonance frequency f1 is as follows:

[0039]

[0040] Where f1 is the Helmholtz resonance frequency, c0 is the speed of sound, S is the opening cross-sectional area of ​​the cavity, l e is the neck length of the cavity opening, V C represents the cavity volume, and ζ represents the damping ratio.

[0041] When the air conditioner is working, air flows into the cavity 113 from the air inlet 111, causing the cavity 113 to make a sound. The principle of the sound is as follows: Fig. 9B As shown, when the airflow flows through the cavity 113 at a certain speed, vortex shedding will occur at the leading edge of the opening of the cavity 113 (i.e., the air inlet 111), and the vortex shedding flow will hit the trailing edge of the opening to generate pressure waves. These pressure waves and vortex motions interact with each other to generate self-excited oscillations with a self-excited oscillation frequency f2:

[0042]

[0043] Where U0 is the air flow velocity; L C is the cavity opening length; N is the order of the shedding vortex, Ma is the Mach number, and γ and are k constants.

[0044] When the self-excited oscillation frequency f2 of the airflow and the Helmholtz resonance frequency f1 of the cavity are close, Helmholtz resonance will occur, forming a strong sound source, such as roar or howling. This narrow-band sound is easily recognized by the human ear and causes irritation to the passengers.

[0045] The partition 120 divides the cavity 113 into at least two cavities 114. By properly setting the volume of the cavity 114, the Helmholtz resonance frequency f1 of the cavity 114 can be made unequal to the self-excited oscillation frequency f2 of the airflow, thereby avoiding resonance when the airflow flows through the cavity 114, thereby avoiding the generation of roaring sound.

[0046] The air conditioning box provided by the present application is based on the Helmholtz resonance principle. By setting an adjustment member and a partition, the volume of the cavity 114 separated by the partition 120 inside the air conditioning box can be adjusted according to different working conditions, so that the Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow maintain an unequal relationship, avoiding resonance when the airflow flows through the cavity 114, thereby avoiding the generation of a roar during the operation of the air conditioning box at the source. In addition, the partition 120 is arranged inside the shell 110, and does not need to occupy additional space outside the air conditioning box 100. When the air conditioning box 100 is installed in some compact environments, it can save layout space.

[0047] In one possible implementation, see Figure 3 As shown, the adjusting member 130 includes a driving device 131, and the driving device 131 is used to drive the partition 120 to move relative to the housing 110. The driving device 131 can provide power, and the driving device 131 can include but is not limited to a combination of one or more of a motor, a hydraulic system or other mechanical devices. The driving device 131 is used to drive the partition 120 to move relative to the housing 110, and can realize the movement of the partition 120 inside the housing 110, thereby changing the volume of the cavity 114.

[0048] In one possible implementation, see Figure 3 As shown, the adjusting member 130 further includes a guide member 132, the guide member 132 is connected to the partition 120, and the partition 120 is used to move along the guide direction of the guide member 132. The guide direction of the guide member 132 can be Figure 3 In the X direction, the partition 120 can move along the X direction or in the opposite direction of the X direction on the guide member 132, and the partition 120 can also be fixed on the guide member 132, and the guide member 132 drives the partition 120 to move along the X direction or in the opposite direction of the X direction. The guide member 132 can have transmission and guiding functions, and can include but is not limited to a combination of one or more of a guide rail, a lead screw or other mechanical devices.

[0049] In one embodiment, the driving device 131 may include a cylinder, the guide member 132 may include a guide rail, the partition 120 may be mounted on the guide rail, the guide rail is fixed inside the housing 110, and does not move relative to the housing 110, the driving device 131, that is, the cylinder, may be connected to the partition 120, and the cylinder directly drives the partition 120 to move on the guide rail. Thus, the partition 120 moves relative to the housing 110 in the X direction or the opposite direction of X, changes the volume of the cavity 114, and avoids the generation of roaring sound.

[0050] In one possible implementation, see Figure 4 and Figure 5As shown, the guide member 132 includes a lead screw 1321, the outer wall surface of the lead screw 1321 has threads, the partition 120 is provided with a threaded hole 121, the threaded hole 121 and the lead screw 1321 are threadedly connected, and the driving device 131 is used to drive the lead screw 1321 to rotate. The partition 120 is installed on the lead screw 1321 through the threaded hole 121. The threads on the outer wall surface of the lead screw 1321 and the threads on the inner wall surface of the threaded hole on the partition 120 can cooperate with each other, so that the partition 120 can be fixed on the lead screw 1321. The lead screw 1321 moves relative to the housing 110 and drives the partition 120 to move relative to the housing 110.

[0051] In one embodiment, the driving device 131 can be a motor, and the guide member 132 can be a lead screw 1321. The motor shaft of the motor and the lead screw can be connected through a coupling or an adapter. The motor runs and provides power, and the lead screw 1321 is connected to the motor to convert the rotational motion of the motor into linear motion. The lead screw 1321 can move along the X direction or the opposite direction of X under the drive of the motor. A ball bearing can be provided between the lead screw 1321 and the partition 120. The lead screw 1321 can drive the partition 120 installed on the lead screw 1321 to move along the X direction or the opposite direction of X, so as to realize the adjustable volume of the cavity 114.

[0052] In a possible implementation, the number of the partitions 120 is at least two, and the at least two partitions 120 are arranged along the thickness direction of the partition 120. The number of the partitions 120 may be multiple, and the multiple partitions 120 may be arranged along the thickness direction of the partition 120 on the guide member 132, for example, see Figure 6 As shown, the plurality of partitions 120 are arranged along the X direction, and the plurality of partitions 120 may be arranged at intervals or in contact with each other. The plurality of partitions 120 are arranged along the thickness direction of the partitions 120, and the plurality of partitions 120 may be arranged along the thickness direction of the partitions 120 ( Figure 6 The air inlet 111 and the air outlet 112 can be better connected to each other by moving the plurality of partitions 120 in the X direction or the reverse direction of the X direction.

[0053] In a possible embodiment, there is at least one partition 120, and the plurality of partitions 120 divide the interior of the housing 110 into a plurality of cavities 114, and the volumes of the plurality of cavities 114 can be adjusted. For example, the number of partitions 120 can be 2, 4, or 5, which are not listed here. Each partition 120 is connected to at least one adjusting member 130. There can be a plurality of adjusting members 130, and a partition 120 is installed on each of the plurality of adjusting members 130. The partition 120 is connected to at least one adjusting member 130. The partition 120 can be moved relative to the shell 110 by at least one adjusting member 130. There may also be multiple partitions 120, each of which is connected to the adjusting member 130. The position of the partition 120 inside the shell 110 and the spacing between different partitions 120 can be accurately controlled by the adjusting member 130, so that the volume of the cavity 114 can be better adjusted according to different working conditions of the air-conditioning box, so that the self-excited oscillation frequency f2 of the airflow is not equal to the Helmholtz resonance frequency f1 of the cavity 114, thereby avoiding the generation of roaring sound.

[0054] The air-conditioning box 100 may include an adjusting device, which is used to adjust the wind direction and air volume of the air-conditioning box 100. Exemplarily, there are 7 adjusting devices inside the air-conditioning box, and the 7 adjusting devices use a combination of different angles to adjust the wind direction and air volume of the air-conditioning box 100 to achieve face blowing, foot blowing, defogger and other combined working conditions of the air-conditioning box 100.

[0055] Different combinations of regulating devices will cause the airflow to form different flow patterns in the shell 110. When the airflow under different flow patterns passes through the cavity 114, different self-excited oscillation frequencies f2 will be generated, which increases the probability of being close to the Helmholtz resonance frequency f1 of the cavity 114, and is more likely to produce a roaring sound. By arranging multiple partitions 120 inside the shell 110, the interior of the shell 110 can be divided to obtain more cavities 114. Multiple partitions 120 can be moved relative to the shell 110 in the X direction or the reverse direction of X to obtain more cavities 114 with adjustable volumes, so that when facing different working conditions of the air-conditioning box 100, the volume of the cavity 114 can be adjusted in time according to the different self-excited oscillation frequencies f2 generated by the airflow more flexibly, so that the self-excited oscillation frequency f2 of the airflow is not equal to the Helmholtz resonance frequency f1 of the cavity 114, thereby avoiding the generation of a roaring sound.

[0056] In one embodiment, see Figure 6As shown, three partitions 120 are arranged inside the housing 110, and an adjusting member 130 is arranged on each of the three partitions 120, that is, one partition 120 is connected to one adjusting member 130. The partition 120 can be installed on a guide member 132 of the adjusting member 130, and the driving device 131 of the adjusting member 130 drives the guide member 132, and the guide member 132 drives the partition 120 to move relative to the housing 110, and the guiding directions of the guide members 132 on different partitions 120 can be parallel.

[0057] In a possible implementation, the thickness of the partition 120 is in the range of 1 mm to 2 mm, so that the partition 120 is arranged inside the housing 110 without occupying too much internal space, reducing the layout pressure of the air conditioning box 100 in the transportation vehicle. In addition, the partition 120 can also ensure that no vibration is generated under the action of flow.

[0058] In one possible implementation, see Figure 7 As shown, the outer edge of the partition 120 has an elastic structure 140 , the elastic structure 140 abuts against the inner wall of the shell 110 , and the elastic structure 140 covers the outer edge of the partition 120 .

[0059] The elastic structure 140 is located between the outer edge of the partition 120 and the inner wall of the shell 110, ensuring that the partition 120 can fit the inner wall of the shell 110 and flexibly adapt to the structure of the inner wall of the cavity 114 as the partition 120 moves relative to the cavity 114. The elastic structure 140 can prevent air leakage from forming a gap between the partition 120 and the shell 110. The elastic structure 140 can be a rubber pad, a soft rubber edge or other structure. It is understandable that the partition 120 can be in a bent shape to adapt to the shape of the shell 110 and to better contact the inner wall of the shell 110. It is understandable that the bent partition 120 can be an integrally formed structure or can be formed by splicing two different plate structures at a certain angle.

[0060] In one possible implementation, see Figure 8As shown, the air conditioning box 100 includes a control system 150, and the control system 150 may include a detection unit, a data processing unit and a control unit. Among them, the detection unit is used to detect the Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow in real time. The data processing unit is used to compare the Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow, and establish a corresponding relationship between the position of the partition 120 inside the shell 110 when the Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow are not equal. The control unit is used to obtain the current Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow from the detection unit, and obtain the position of the partition 120 inside the shell 110 from the data processing unit. The control unit controls the partition 120 to move relative to the shell 110 by controlling the adjustment member.

[0061] The control system 150 can be electrically connected to the driving device 131. The control system 150 can control the driving device 131 accordingly by comparing the magnitude relationship between the Helmholtz resonance frequency f1 of the cavity 114 and the self-excited oscillation frequency f2 of the airflow, so as to realize intelligent adjustment of the movement of the partition 120 relative to the inside of the shell 110.

[0062] The air conditioning box 100 has multiple adjustment devices for adjusting wind direction and wind speed, so that the air conditioning box 100 has multiple working conditions, and multiple working conditions correspond to multiple wind speeds. The control system 150 can intelligently adjust the position of the adjustment partition 120 according to different working conditions to avoid roaring sounds under different working conditions, so as to achieve the air conditioning box 100 without roaring sounds under all working conditions.

[0063] The present application also provides a means of transport, which includes, in addition to common components such as an engine or motor, wheels, a steering wheel, and a transmission, an air conditioning box 100 as described in any of the above embodiments. The air conditioning box 100 can be located in the engine compartment of the means of transport, and is used to adjust the temperature inside the vehicle and provide a good environment and vision for the driver and passengers.

[0064] The means of transport described in any of the above embodiments of the present application are all described by taking new energy vehicles as an example.
