Description
Technical Field
[0001] The utility model relates to the field of air-conditioning air-guide blades, in particular to a locking mechanism for air-conditioning air-guide blades. Background Art
[0002] Wall-mounted air conditioners are a common type of RV air conditioning system. Typically installed on a side wall, they regulate the interior temperature through cooling or heating, providing a comfortable living environment for passengers. Existing wall-mounted air conditioners typically maintain a closed blade position through the positioning torque provided by a return spring and a drive motor.
[0003] However, during RV driving, the upper and lower air guide vanes, which are in a closed state, are subjected to strong vibration due to bumpy roads. This vibration, combined with the acceleration of the vanes' own weight, often generates a torque greater than the spring return torque and the drive motor's positioning torque, causing the upper and lower air guide vanes to open abnormally and vibrate repeatedly with the bumpy road. This long-term, repeated vibration can damage the upper and lower air guide vanes and the internal structure of the drive motor, leading to failure. Furthermore, the abnormal opening of the upper and lower air guide vanes can lead users to mistakenly believe that the air conditioner is malfunctioning. Summary of the Invention
[0004] Based on this, the purpose of the present invention is to overcome the defects or shortcomings of the existing technology and provide an air conditioner blade locking mechanism, whose structure can prevent the upper and lower air guide blades in the closed state from opening abnormally due to strong vibration, thereby improving the service life of the air conditioner.
[0005] The utility model is realized through the following technical solutions: an air-conditioning air-guide blade locking mechanism, comprising a fixed plate, a rotary driver and a rocker arm, wherein the rotary driver is fixedly mounted on the fixed plate, the output end of the rotary driver is connected to one end of the rocker arm, and the other end of the rocker arm is provided with a first limiting component, the first limiting component matches the second limiting component on the air-conditioning air-guide blade rotating shaft to limit the air-guide blade rotating shaft in a closed state.
[0006] Compared with the prior art, the air-conditioning air-guide blade locking mechanism provided by the utility model designs a rocker arm, arranges a first limit component on the rocker arm, and arranges a second limit component on the air-guide blade rotating shaft. By arranging a rotary driver to drive the rocker arm to rotate, the first limit component and the second limit component are abutted or disengaged, thereby realizing the locking and unlocking of the air-conditioning air-guide blade. Without affecting the operation of the upper and lower air-guide blades, the upper and lower air-guide blades in the closed state can be prevented from opening abnormally due to strong vibration, thereby improving the service life of the air-conditioning. The air-conditioning air-guide blade locking mechanism is particularly suitable for RVs. When the RV is driving and the road is bumpy, causing the body to have a large up and down shaking and vibration, the upper and lower air-guide blades of the air-conditioning can be locked.
[0007] Furthermore, the first limiting component is a first boss extending outward from the side of the swing rod. Thus, the design of the first boss simplifies the overall structure of the locking mechanism and reduces the complexity of the locking mechanism.
[0008] Furthermore, the second limiting component is a second boss extending outward from the outer peripheral surface of the air guide blade shaft. Thus, the second boss is designed on the air guide blade shaft, and the first boss and the second boss abut against each other, thereby limiting the air guide blade.
[0009] Furthermore, the fixing plate is provided with a limit structure for limiting the rotation angle of the swing arm. Thus, by designing the limit structure on the fixing plate, the swing arm is ensured to move within a predetermined angular range, preventing the swing arm from exceeding the safe range and causing damage to the internal structure of the air conditioner when an abnormality occurs in the rotary drive.
[0010] Furthermore, the limiting structure includes a relief groove provided in the middle of the fixed plate and a limiting member provided at the opening of the relief groove. The swing arm is disposed within the relief groove and swings between the relief groove and the limiting member. Thus, by designing a relief groove on the fixed plate to accommodate the swing arm, the locking mechanism becomes more compact, thereby saving space. By designing a limiting member at the opening of the relief groove, the swing arm's rotation angle within the relief groove is limited.
[0011] Furthermore, the limiting member is a long, strip-shaped limiting block. When the swing arm rotates to the limiting member, the swing arm abuts the limiting block. The first boss includes a supporting portion and a stopping portion for abutting the second boss. The supporting portion extends from a side of the swing arm, and the stopping portion is located at an end of the supporting portion away from the swing arm and extends toward the air guide blade shaft of the air conditioner. Thus, the long, strip-shaped limiting block enables the swing arm to accurately stop at a predetermined angular position during its swinging process, preventing excessive swinging. The supporting portion provides stable support for the stopping portion, and the stopping portion increases the contact area between the first and second bosses, making it more capable of withstanding the force applied by the second boss, thereby forming a stable limit on the air guide blade shaft.
[0012] Furthermore, the avoidance slot includes interconnected shaft mounting slots and swinging space slots. The rotary actuator is fixed to one side of the fixed plate, with its output end extending into the shaft mounting slot and connecting to one end of the rocker arm. The first boss extends from the other end of the rocker arm, away from the rotary actuator. Thus, the shaft mounting slot provides a precise mounting position for the rocker arm's shaft, while the swinging space slot provides sufficient space for the rocker arm to swing. By dividing the shaft mounting slot and the swinging space slot, the rocker arm is able to move freely within a limited space.
[0013] Furthermore, the side of the swing arm's rotating shaft away from the rotary driver is flush with the side of the fixed plate away from the rotary driver, the other side of the swing arm protrudes from the fixed plate, and the stopper is provided on the side of the fixed plate closer to the rotary driver. Thus, with the above arrangement, except for the first boss on the swing arm, the remaining parts of the swing arm and the stopper do not hinder the rotation of the rotating shaft on the air guide blade. This design also makes the overall structure simpler and more compact.
[0014] The utility model also provides a wall-mounted air conditioner, an air conditioner shell, upper and lower air guide blades and the air conditioner air guide blade locking mechanism as described above, the air conditioner air guide blade locking mechanism is fixedly installed on one side of the air outlet of the air conditioner shell through its fixing plate, the rotating shaft of the upper and lower air guide blades is provided with a second limiting component, the first limiting component in the air conditioner air guide blade locking mechanism is matched with the second limiting component to limit the upper and lower air guide blades in the closed state.
[0015] The utility model also provides a recreational vehicle, comprising the wall-mounted air conditioner as described above.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] Example 1:
[0024] The air guide blade locking mechanism provided in this embodiment is primarily used in wall-mounted air conditioners. Wall-mounted air conditioners are heat exchange devices mounted on indoor walls, for example, to cool or heat the air. More specifically, they are used in RVs. By providing an air guide blade locking mechanism at the air outlet of the wall-mounted air conditioner, the upper and lower air guide blades located therein are restrained, preventing the closed upper and lower air guide blades from opening unexpectedly due to strong vibrations caused by bumpy roads while the RV is driving.
[0025] See also Figure 1 The air conditioner air guide blade locking mechanism includes a fixed plate 10, a rotary driver 20 and a rocker arm 30. The rotary driver 20 is fixedly mounted on the fixed plate 10. The output end of the rotary driver 20 is connected to one end of the rocker arm 30. The other end of the rocker arm 30 is provided with a first limiting component 33. The first limiting component 33 matches the second limiting component 41 on the air guide blade shaft 40 of the air conditioner to limit the air guide blade shaft 41 in the closed state.
[0026] Therefore, by designing the rocker arm 30, a first limit component 33 is set on the rocker arm 30, and a second limit component 41 is set on the air guide blade shaft 40, and the rocker arm 30 is driven to rotate by setting a rotary driver 20, the first limit component 33 is matched with the second limit component 41, thereby realizing the limitation of the air guide blade of the air conditioner. Without affecting the operation of the upper and lower air guide blades, the upper and lower air guide blades in the closed state can be avoided from being abnormally opened due to strong vibration, thereby improving the service life of the air conditioner. The air guide blade locking mechanism of the air conditioner is particularly suitable for RVs. When the RV is driving and the road is bumpy and causes the body to have a large up and down shaking and vibration, the upper and lower air guide blades of the air conditioner can be locked.
[0027] In this embodiment, the fixing plate 10 is used to be fixed to the air conditioner housing. Of course, in other alternative embodiments, the fixing plate 10 is not limited to being fixedly installed on the air conditioner housing, but can be fixedly installed on the internal structure of the air conditioner.
[0028] In this embodiment, the rotary actuator 20 is a drive motor. The drive motor is fixed to the fixed plate by bolts or screws. Of course, in other alternative embodiments, the rotary actuator is a rotary cylinder, which is fixed to the fixed plate by bolts or screws.
[0029] Please also see Figure 2 In this embodiment, the first limiting component 33 is a first boss extending outward from the side of the swing rod 30. Therefore, by designing the first boss on the swing rod, the overall structure of the locking mechanism is simplified, thereby reducing the complexity of the locking mechanism.
[0030] Specifically, the rocker arm 30 includes a rotating shaft 31 and a rocker arm 32. The rotating shaft 31 is annular and sleeved on the output shaft of the drive motor. The rocker arm 32 extends outward from the outer peripheral surface of the rotating shaft 31, and the cross-sectional shape of the rocker arm 32 is rectangular. The first limiting component 33 is located at the end of the rocker arm 32 away from the rotating shaft. The first limiting component is a first boss extending outward from the side of the rocker arm 32. The extension direction of the first boss is the same as the axial direction of the rotating shaft 31. Preferably, the rocker arm 30 is in the shape of a bar. Of course, in other alternative embodiments, the rocker arm 30 is not limited to a bar shape and can be in the shape of an arc or the like.
[0031] In this embodiment, the second limiting component 41 is a second boss extending outward from the outer peripheral surface of the air guide blade shaft 40. Therefore, a second boss is designed on the air guide blade shaft 40, and the air guide blade is limited by the mutual abutment of the first boss and the second boss. Preferably, the second boss and the air guide blade shaft 40 are integrally formed. Of course, in other replaceable embodiments, the second boss can be detachably mounted on the air guide blade shaft 40 by means of clipping or bolt locking. Preferably, the cross-sectional shape of the second boss is a rectangle. Of course, in other replaceable embodiments, the cross-sectional shape of the second boss can be a circle or other polygon.
[0032] Please also see Figure 3 In this embodiment, the fixed plate 10 is provided with a limiting structure for limiting the rotation angle of the swing arm 30. Thus, by designing a limiting structure on the fixed plate 10, the swing arm 30 is ensured to move within a predetermined angular range, preventing the swing arm 30 from exceeding a safe range when the rotary actuator 20 malfunctions, thereby preventing damage to the internal structure of the air conditioner.
[0033] Specifically, the limiting structure includes an avoidance groove 11 provided in the middle of the fixed plate 10 and a limiting member 12 provided at the opening of the avoidance groove 11. The rocker arm 30 is provided in the avoidance groove 11 and swings between the avoidance groove 11 and the limiting member 12. Thus, by designing the avoidance groove 11 on the fixed plate 10 to accommodate the rocker arm 30, the locking mechanism structure is made more compact, thereby saving the space occupied by the locking mechanism. By designing the limiting member 12 at the opening of the avoidance groove 11, the rotation angle range of the rocker arm 30 in the avoidance groove 11 is limited. Preferably, the limiting member 12 is integrally formed with the fixed plate 10. Of course, in other alternative embodiments, the limiting member 12 is detachably provided on the fixed plate 10 by screws or clipping.
[0034] Preferably, the avoidance slot 11 includes a connecting shaft mounting slot 111 and a swinging space slot 112. The rotary actuator 20 is fixed to one side of the fixed plate 10, with its output end extending into the shaft mounting slot 111 and connected to one end of the rocker arm 30. The first boss extends from the other end of the rocker arm 30, away from the rotary actuator 20. Thus, the shaft mounting slot 111 provides a precise mounting position for the rocker arm's shaft, while the swinging space slot 112 provides sufficient space for the rocker arm to swing. By dividing the shaft mounting slot and the swinging space slot, the rocker arm is ensured to move freely within a limited space.
[0035] Preferably, the stopper 12 is an elongated stopper. When the swing arm 30 rotates to the stopper 12, the swing arm 30 abuts the stopper. The first boss includes a support portion 331 and a stopper portion 332 for abutting the second boss. The support portion 331 extends from the side of the swing arm 30, and the stopper portion 332 is located at the end of the support portion 331 distal from the swing arm 30 and extends toward the air guide blade shaft 40 of the air conditioner. Thus, the elongated stopper allows the swing arm 30 to precisely stop at a predetermined angular position during its swinging process, preventing excessive swinging. The support portion 331 provides stable support for the stopper portion 332, while the stopper portion 332 increases the contact area between the first and second bosses, making it more capable of withstanding the force applied by the second boss, thereby firmly limiting the air guide blade shaft 40. Preferably, the stopper has a rectangular cross-section. Of course, in other alternative embodiments, the cross-sectional shape of the limiting block is not limited to a rectangle, and may be other polygons or a circle.
[0036] In this embodiment, the side of the rotating shaft 31 of the swing arm 30 away from the rotary driver 20 is flush with the side of the fixed plate 10 away from the rotary driver 20. The other side of the swing arm 30 protrudes from the fixed plate 10, and the stopper is provided on the side of the fixed plate 10 close to the rotary driver 20. Thus, with the above arrangement, except for the first boss on the swing arm 30, the remaining parts of the swing arm 30 and the stopper do not hinder the rotation of the air guide blade rotating shaft 40. This design also makes the overall structure simpler and more compact.
[0037] In this embodiment, the fixing plate 10 is made of a resin material. The rocker arm 30 is also made of a resin material. Of course, in other alternative embodiments, the fixing plate 10 can be made of a sheet metal material, and the rocker arm 30 can be made of a sheet metal material. Thus, both the fixing plate 10 and the rocker arm 30 are made of a resin material or a sheet metal material, which helps reduce the overall weight of the locking mechanism while ensuring sufficient strength and rigidity, thereby achieving lightweight requirements.
[0038] In this embodiment, the wind guide blade shaft 40 is designed to be integrated with the wind guide blade. Of course, in other alternative embodiments, the wind guide blade shaft 40 can be designed to be separate from the wind guide blade.
[0039] When the air conditioner is not in use, the air guide blades are in a closed state, and the rocker arm is driven to rotate by the rotary driver. When the rocker arm rotates to a position in contact with the limit member, the first boss on the rocker arm abuts against the second boss on the air guide blade shaft, thereby locking the air guide blade shaft; when the air conditioner needs to be used, the rocker arm is driven to rotate in the opposite direction by the rotary driver. When it rotates to contact the surface of the fixed plate, the first boss and the second boss on the rocker arm do not interfere with each other, thereby unlocking the air guide blade shaft.
[0040] Compared with the prior art, the air-conditioning air-guide blade locking mechanism provided by the utility model designs a rocker arm, arranges a first limit component on the rocker arm, and arranges a second limit component on the air-guide blade rotating shaft. By arranging a rotary driver to drive the rocker arm to rotate, the first limit component and the second limit component are abutted or disengaged, thereby realizing the locking and unlocking of the air-conditioning air-guide blade. Without affecting the operation of the upper and lower air-guide blades, the upper and lower air-guide blades in the closed state can be prevented from opening abnormally due to strong vibration, thereby improving the service life of the air-conditioning. The air-conditioning air-guide blade locking mechanism is particularly suitable for RVs. When the RV is driving and the road is bumpy, causing the body to have a large up and down shaking and vibration, the upper and lower air-guide blades of the air-conditioning can be locked.

The rotating shafts of the upper and lower air guide blades are provided with a second limiting assembly. The first limiting assembly in the air conditioner air guide blade locking mechanism matches the second limiting assembly to limit the upper and lower air guide blades in the closed state. It should be noted that the internal structure and components of the wall-mounted air conditioner are all prior art and will not be described in detail here.
