[0029] Below, reference is made to Figures 1 to 6 Various embodiments of the present disclosure are described in detail.

[0030] As shown in Figure 1 , the air conditioning module 200 included in the vehicle of the present disclosure includes a housing 201 and dampers 1, 2. The housing 201 is installed in the vehicle, and an air flow passage is provided therein, and optionally an evaporator for cooling air, a heater core for heating air, a mixing mechanism for mixing cold air and warm air at a prescribed mixing ratio, etc. Figure 1 Two dampers 1, 2 are shown in the middle, but the number of dampers is not limited by the present disclosure.

[0031] As shown in Figure 1 , the housing 201 includes a main housing 202. As shown in Figure 3 and 4 , the rotation shafts 9, 11 of the two dampers 1, 2 are rotatably provided on the main housing 202.

[0032] As shown in Figures 2 to 4 , the air conditioning module 200 further includes a lever 4 and a follower. The lever 4 is slidably provided on the main housing 202. The follower is provided on the rotation shafts 9, 11 of the dampers 1, 2. The follower is slidably engaged to the lever 4 to be driven by the lever 4 when the lever 4 slides, thereby driving the dampers 1, 2 to rotate on the main housing 202. The present disclosure realizes the rotation of the dampers by translational motion.

[0033] In addition, as shown in Figure 3 , the air conditioning module 200 further includes a motor 3, which includes a motor output shaft. Referring again to Figure 1 , the motor 3 is provided in a motor housing 100, which is provided on the side of the main housing 202.

[0034] As shown in Figure 5 , the lever 4 has a trajectory groove 20. As shown in Figures 3 to 4 , the follower includes sliding pins 8, 10 that can slide in the trajectory groove 20, and the sliding pins 8, 10 are fixed to the rotation shafts 9, 11 of the dampers 1, 2. Specifically, the sliding pin 8 is fixed to the rotation shaft 9 of the damper 1, and the sliding pin 10 is fixed to the rotation shaft 11 of the damper 2. The rotation shafts 9, 11 are respectively provided with gear mechanisms, and the sliding pins 8, 10 are respectively fixed to the corresponding gear mechanisms, for example, protruding along the extension axis of the respective rotation shafts 9, 11. The trajectory groove 20 can have a curved or bent form, and one or more observation windows are provided thereon for observing the position of the sliding pins. By observing the position of the sliding pins, the state of the dampers can be determined. By moving the sliding pins 8, 10 to different positions in the trajectory groove 20, the dampers 1, 2 can be opened and closed, and switching between different modes can be achieved.

[0035] As shown in Figure 4As shown, the housing 201 comprises positioning elements 14, 15 arranged on the main housing 202, which slidably support the bar 4. As shown, Figure 3 As shown, the positioning elements 14, 15 are arranged between the bar 4 and the main housing 202. As shown, Figure 4 The positioning elements 14, 15 can have the form of pins. Furthermore, the positioning elements 14, 15 are arranged at a distance to the rotation axes 9, 11, respectively.

[0036] As shown, Figure 5 The bar 4 is provided with positioning grooves 18, 19, which receive the positioning elements 14, 15. Specifically, the positioning groove 18 is for receiving the positioning element 14, and the positioning groove 19 is for receiving the positioning element 15. The positioning grooves 18, 19 can extend along the extension axis A of the bar 4. For example, the positioning grooves 18, 19 are arranged at two opposite sides of the bar 4 in a direction perpendicular to the extension axis A of the bar 4. In this way, the support of the bar 4 when sliding is more stable.

[0037] By arranging the positioning elements and the positioning grooves, not only the bar can be supported when sliding, but also movement of the bar in a plane substantially parallel to the side wall of the main housing can be prevented.

[0038] As shown, Figures 3 to 4 The air conditioning module 200 further comprises a drive wheel 5, which is rotatably arranged on the main housing 202 and in driving connection with the bar 4 to drive the bar 4 to slide on the main housing 202. The drive wheel 5 is connected to the motor output shaft 6 and rotatable under the drive of the motor output shaft 6. For example, the drive wheel 5 comprises a wheel shaft 7, which is connected to the motor output shaft 6.

[0039] Again referring to Figures 3 to 4 The housing 201 has housing limiting portions 12, 13 arranged on the main housing 202, which slidably abut against the bar 4. The housing limiting portions and the drive wheel 5 are arranged on two sides of the bar 4, respectively, to clamp the bar 4, as shown, Figure 3 Two housing limiting portions are shown in the figure to achieve stable limiting for a longer bar 4. Of course, other numbers of housing limiting portions are possible, and even in the case of a shorter bar, only one limiting portion is possible. By arranging the housing limiting portions, movement of the bar in a plane substantially parallel to the side wall of the main housing, especially in a direction transverse to the extension axis of the bar, can be further prevented.

[0040] As shown, Figure 4As shown, the drive wheel 5 and at least two outer casing limiting parts 12 and 13 are respectively located at the three vertices of a triangle T, which is shown by the dotted line in the figure. In this way, the position of the rod 4 can be restricted during sliding, ensuring that the rod 4 does not deviate from its path.

[0041] like Figure 5 As shown, the rod 4 has a rack portion 16, which is provided with teeth 23 that engage with the drive wheel 5. The rod 4 can slide translationally by means of the teeth 23 that mesh with the teeth 21 of the drive wheel 5.

[0042] like Figure 6 As shown, the drive wheel 5 has a wheel limiting part 22, and the rack part 16 is arranged between the main housing 202 and the wheel limiting part 22. Figure 4 As shown, the wheel limiting portion 22 is used to abut against the rack portion 16 in the direction toward the main housing 202. For example, the wheel limiting portion 22 is a protrusion extending radially from the outer edge of the drive wheel 5. In this way, movement of the rod in the direction away from the main housing can be prevented.

[0043] like Figure 4 As shown, at least one of the outer casing limiting portions 12 and 13 includes an L-shaped element. One arm of the L-shaped element is connected to the main housing 202, and the other arm is outside the main housing 202, hooking the rod 4 in a direction toward the main housing 202. Specifically, the other arm stops the rod in a direction away from the main housing, so as to prevent the rod from moving away from the main housing on both sides of the rod 4 together with the wheel limiting portion 22.

[0044] As described above, the air conditioning module disclosed herein achieves damper actuation and mode switching through a simple mechanical structure, thus having a compact structure and low space requirements.

[0045] The vehicle disclosed herein includes the air conditioning module 200 as described above. The vehicle may be a motor vehicle or an electric vehicle. The vehicle of this disclosure therefore possesses the various advantages described above regarding the air conditioning module.

[0046] Furthermore, the technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention, in order to achieve the purpose of this disclosure.
