Description

Technical Field

[0001] The present invention relates to the technical field of automotive air conditioners, and particularly to an air distributor. Background Art

[0002] The air distributor on a vehicle-mounted air conditioner is a key component for regulating and distributing the airflow direction, air volume, and temperature of the air outlet of the air conditioner. Its main function is to distribute the cold / hot air generated by the air conditioning system to different areas, such as the face, feet, windshield, etc., according to the driving and riding needs, so as to achieve precise control of the vehicle interior environment and improve comfort.

[0003] The patent publication number of the existing patent application is: CN213056621U, and the publication date is April 27, 2021. The name of this patent is "An air outlet structure with gentle air feeling for an air conditioner and a vehicle-mounted air conditioner". This patent includes a housing. The interior of the housing is hollow and forms an air duct. One end of the air duct is an air inlet, and the other end bifurcates to form a first air outlet channel and a second air outlet channel. The air outlet end of the first air outlet channel is provided with a first air outlet, and a first air outlet mechanism is provided at the first air outlet. The air outlet end of the second air outlet channel is provided with a second air outlet, and a second air outlet mechanism is provided at the second air outlet. A first air damper structure is arranged at the air inlet end of the first air outlet channel, and the first air damper structure is used to control the opening or closing of the first air outlet channel. By controlling the opening of the first air damper structure, it is realized that the first air outlet mechanism and the second air outlet mechanism can blow air simultaneously, without reducing the air volume, increasing the air outlet area, and reducing the air outlet speed, so as to achieve the purpose of gentle air feeling.

[0004] The above application has deficiencies. Conventional air distributors generally have problems such as the sealing member in the wind blocking component failing or debris adhering, resulting in air leakage due to improper closing. In particular, the abnormal noise problem caused by the tremor of the wind deflector under high-speed air flow conditions also needs to be solved. Although the mainstream magnetic adsorption sealing structure on the market can improve the sealing performance in the closed state, the additional electromagnetic mechanism significantly increases the manufacturing cost. Summary of the Invention

[0005] The purpose of the present invention is to provide an air distributor to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An air distributor includes a housing provided with at least two ventilation openings, and further includes a pair of wind deflector assemblies which are respectively rotatably installed in each ventilation opening. A limit accommodation groove adapted to the opening and closing trajectory of the wind deflector assembly is formed in the housing. A driving motor is installed on the outer wall of the housing. A turntable is installed on the output shaft of the driving motor. Trajectory grooves adapted to each wind deflector assembly are respectively formed on the end face of the turntable. An elastic pressing member has one end elastically hinged inside the housing and the other end abutted and cooperated with one of the wind deflector assemblies. When the driving motor drives the turntable to rotate, each wind deflector assembly is driven to swing through the trajectory groove, so as to realize the alternating opening and closing and air guiding of each ventilation opening. And when one of the wind deflector assemblies is opening, the elastic pressing member continuously collides with it, and when it is closing, the elastic pressing member applies a force to it in the closing direction.

[0008] Preferably, an installation frame is fixedly connected to the outer wall of the housing by clamping. A motor mounting seat is fixed on one side of the installation frame, and an accommodation cavity for accommodating the turntable is formed on the other side. A plurality of anti - detachment blocks are annularly distributed in the accommodation cavity.

[0009] Preferably, the wind deflector assembly includes a wind deflector plate. A central shaft rod is installed on the wind deflector plate. One end of the central shaft rod penetrates through the housing and a crank is installed. One end of the crank is inserted into the trajectory groove.

[0010] Preferably, the elastic pressing member includes a cross bar installed in the housing. A connecting frame is elastically hinged on the cross bar. One end of the connecting frame is fixedly connected with a pressing rod. Anti - contact racks which are abutted and cooperated with the pressing rod are symmetrically and fixedly connected to one side of the wind deflector plate.

[0011] Preferably, a sleeve is rotatably sleeved at the end of the cross bar. A driven gear ring is fixedly connected to one end of the sleeve. A sector anti - contact tooth which meshes with the bottom of the driven gear ring is fixedly connected to one side of the wind deflector plate. A sleeve is coaxially sleeved at the other end of the sleeve. A top spring is installed between the sleeve and the shaft sleeve. A pressing tooth is fixedly connected to the end face of the sleeve. The other end of the connecting frame is symmetrically installed and sleeved on a shaft sleeve on the cross bar. A torsion spring is installed between the shaft sleeve and the cross bar. An anti - contact block which is abutted and cooperated with the pressing tooth is fixedly connected to the end face of the shaft sleeve.

[0012] Preferably, a sealing strip is arranged at the edge of the wind deflector plate. The pressing rod synchronously presses the sealing strip and the wind deflector plate. Arc anti - contact grooves which are axially coincident are respectively formed on the wind deflector plate and the sealing strip. And an anti - deviation docking groove is formed on one side of the inner wall of the limit accommodation groove. The arc anti - contact groove and the anti - deviation docking groove are both matched with the pressing rod. When the wind deflector plate is fully opened, the pressing rod enters the arc anti - contact groove and the anti - deviation docking groove.

[0013] Preferably, a closing anti-loosening part is rotatably installed on one side of the shell, and one end of the closing anti-loosening part is transmission connected to one of the windshield components. When the windshield component is closed, the friction between the closing anti-loosening part and the windshield component increases. At this time, the other windshield component is closed and plugged into the closing anti-loosening part.

[0014] Preferably, the closed anti-loosening component includes a connecting shaft rod passing through one side of the shell, the central shaft rod is fixedly connected with a fan-shaped transmission tooth on one side of the wind shield, one end of the connecting shaft rod is fixedly connected with a driven gear meshing with the fan-shaped transmission tooth, and the other end of the connecting shaft rod is fixedly connected with a cam, and an elastic band is sleeved between the two cranks to abut against the protrusion of the cam.

[0015] Preferably, the end face of the driven gear is fixedly connected with an abutment plate, and a slot for plugging in another wind shield component is fixedly installed on the outer circumferential surface of the abutment plate, and when the connecting shaft drives the cam protrusion to abut against the inner wall of the elastic band, the notch of the slot is on the movable path of the connector.

[0016] Preferably, an abutment spring is installed in the arc-shaped abutment groove on the inner side of the sealing strip, and the end of the abutment spring is fixedly connected to a top cover. When the pressure rod enters the arc-shaped abutment groove, the end of the pressure rod abuts and cooperates with the top cover.

[0017] In the above technical scheme, a turntable with a specific trajectory groove is set for linkage, and the dual action mechanism of the elastic pressure piece is cooperated to realize the alternating or synchronous opening and closing of multiple air vents to guide the wind under the drive of a single motor. Among them, the adaptation design of the limit accommodating groove and the motion trajectory of the wind shield component solves the problem of motion interference of the traditional wind divider. The elastic pressure piece implements collision excitation and closing force compensation respectively during the opening and closing process of the wind shield component, which makes the elastic abutment vibrate to shake off the attached debris during the opening process of the wind shield component, and allows the wind shield component to receive additional force from the elastic abutment after closing, thereby significantly improving the sealing efficiency of the wind shield component and reducing the noise generated by the closed wind shield component when high-speed airflow passes through.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-8 , a wind distributor provided by an embodiment of the present invention includes a housing 1 having at least two ventilation openings 101, and further includes a pair of wind blocking components 2 which are respectively rotatably installed in each ventilation opening 101. A limit receiving groove 102 adapted to the opening and closing trajectory of the wind blocking component 2 is provided in the housing 1. A driving motor 3 is installed on the outer wall of the housing 1. A turntable 301 is installed on the output shaft of the driving motor 3. Trajectory grooves 302 adapted to the respective wind blocking components 2 are provided on the end face of the turntable 301. An elastic pressing member 4 has one end elastically hinged inside the housing 1 and the other end abuts and cooperates with one of the wind blocking components 2. When the driving motor 3 drives the turntable 301 to rotate, the respective wind blocking components 2 are driven to swing through the trajectory grooves 302, so as to alternately open and close the ventilation of each ventilation opening 101. And when one of the wind blocking components 2 is opening, the elastic pressing member 4 continuously collides with it. When it is closing, the elastic pressing member 4 applies a force to it in the closing direction.

[0033] Specifically, the shell 1 is the main body of the air divider, wherein at least two vents 101 are provided on the shell 1 for switching the air flow channels, a limit accommodating groove 102 matching the movement trajectory of the windshield component 2 is provided in the shell 1, the depth of the limit accommodating groove 102 plus the width of the inner cavity of the shell 1 just matches the width of the windshield component 2, and the shape of the limit accommodating groove 102 matches the opening and closing swing range of the windshield component 2, ensuring that there is no mechanical interference during the independent swinging of each windshield component 2, the hinged windshield component 2 in the shell 1 is located at the air duct that controls the opening and closing of the corresponding vents 101, the driving motor 3 is fixed on the outside of the shell 1, and its output shaft is connected to the turntable 301, and two track grooves 302 are provided on the end face of the turntable 301, and the central axis of the windshield component 2 is connected to the track groove 302 through the connecting component. 02 transmission is connected together, when the motor drives the turntable 301 to rotate, the different curve designs of the two track grooves 302 ensure that the two windshield components 2 can be opened and closed at the same time and alternately, so as to realize the rotation of wind guide of each vent 101, and the elastic pressure member 4 can press one of the windshield components 2. During the opening process of the windshield component 2, the elastic abutment can continuously make the windshield component 2 vibrate, thereby shaking off the debris attached to the windshield component 2. After the windshield component 2 is closed, the pre-tightening force direction of the elastic pressure member 4 is also consistent with the closing direction of the windshield component 2, so that the sealing performance of the windshield component 2 is greatly improved. Through the coordinated design of mechanical linkage and elastic compensation, precise control of multiple vents 101 can be achieved with a single motor, and both self-cleaning and high sealing performance are achieved.

[0034] Compared with the prior art, the embodiment of the present invention realizes the alternating or synchronous opening and closing of multiple air vents 101 driven by a single motor to guide the air by setting a turntable 301 with a specific trajectory groove 302 for linkage, and cooperates with the dual action mechanism of the elastic pressure member 4, wherein the adaptation design of the limit accommodating groove 102 and the motion trajectory of the wind shield component 2 solves the problem of motion interference of the traditional wind divider, and the elastic pressure member 4 implements collision excitation and closing force compensation respectively during the opening and closing process of the wind shield component 2, so that the elastic abutment member vibrates during the opening process of the wind shield component 2 to shake off the attached debris, and the wind shield component 2 can be subjected to additional force from the elastic abutment member after closing, thereby significantly improving the sealing efficiency of the wind shield component 2 and reducing the noise generated by the closed wind shield component 2 when high-speed airflow passes through.

[0035] In a further embodiment of the present invention, a mounting bracket 5 is fixedly clamped to the outer wall of the housing 1. On one side of the mounting bracket 5, a motor mounting seat 501 is fixed, and on the other side, a receiving cavity 502 for receiving the turntable 301 is provided. A number of anti - detachment locking blocks 503 are annularly distributed in the receiving cavity 502. Specifically, the mounting bracket 5 is fixedly attached to the outer wall of the housing 1 by a clamping method. The mounting bracket 5 is made of integrally formed engineering plastic material. On one side thereof, there is a motor mounting seat 501. The driving motor 3 is fixed to the outside of the housing 1 by bolts. On the other side of the mounting seat, there is a circular receiving cavity 502 with an inner diameter slightly larger than the diameter of the turntable 301 for receiving the turntable 301 and restricting its radial offset. A plurality of anti - detachment locking blocks 503 are evenly distributed along the circumference of the inner wall of the receiving cavity 502. Before the turntable 301 enters the receiving cavity 502, it will push the anti - detachment locking blocks 503 open. After the turntable 301 enters, the anti - detachment locking blocks 503 cooperate with the edge of the outer end face of the turntable 301 to prevent the turntable 301 from disengaging during high - speed rotation, while allowing the turntable 301 to freely rotate in the cavity. The mounting bracket 5 and the housing 1 are quickly disassembled and assembled through a snap - type connecting member, which is convenient for maintenance. When the driving motor 3 operates, the turntable 301 rotates in the receiving cavity 502, and the anti - detachment locking blocks 503 suppress the axial displacement of the turntable 301 through mechanical limitation, ensuring the transmission stability of the track groove 302 and the connecting rod of the windshield assembly 2; the rigid structure of the mounting bracket 5 effectively disperses the motor vibration and reduces the noise. At the same time, the clamping design simplifies the modular assembly process of the motor and the turntable 301, improving the reliability and maintenance efficiency of the equipment.

[0036] In a further embodiment of the present invention, the wind shield assembly 2 includes a wind shield plate 201, on which a central shaft rod 202 is installed. One end of the central shaft rod 202 penetrates through the housing 1 and is equipped with a crank 203. One end of the crank 203 is inserted into the track groove 302. Specifically, the central shaft rod 202 penetrates through the side wall of the housing 1 through a sealed bearing and extends to the outside. The exposed end of the central shaft rod 202 is fixedly connected with an L-shaped crank 203 through a keyway. The free end of the crank 203 is embedded in the track groove 302 of the turntable 301, and the two are in clearance fit. A double-layer sealing rubber ring is arranged at the penetration of the housing 1 and the central shaft rod 202 to prevent air leakage. When the wind shield plate 201 is closed, it closely fits with the inner side wall of the limit receiving groove 102 to prevent the air flow from passing through the wind shield plate 201 and discharging from the corresponding ventilation opening 101. When the driving motor 3 drives the turntable 301 to rotate, the change in the curve profile position of the track groove 302 drives the crank 203 to swing, and then drives the central shaft rod 202 and the wind shield plate 201 to rotate around the axis, realizing the opening and closing control of the ventilation opening 101. The cranks 203 of the two wind shield assemblies 2 are inserted into the respective track grooves 302 of the same turntable 301 with a phase difference, ensuring that during the continuous rotation of the turntable 301, there are four states of alternating opening and closing and synchronous opening and closing between the wind shield assemblies 2 corresponding to the two ventilation openings 101. The elastic pressing member 4 removes dust by high-frequency collision when the wind shield plate 201 is opened, and enhances the pressing effect between the wind shield plate 201 and the limit receiving groove 102 in the housing 1 through a pre-tightening force when closed, ultimately realizing low-noise and high-sealing alternating air guiding.

[0037] In a further embodiment of the present invention, the elastic pressing member 4 includes a cross bar 401 installed in the housing 1. A connecting frame 402 is elastically hinged on the cross bar 401. One end of the connecting frame 402 is fixedly connected with a pressing rod 403. On one side of the wind shield plate 201, there are symmetrically fixedly connected abutting racks 207 that are in abutting cooperation with the pressing rod 403. Specifically, the cross bar 401 is horizontally fixed in the housing 1, and the pressing rod 403 is also horizontally pressed on the wind shield plate 201. The connecting frame 402 is used to fix the pressing rod 403 and enable the pressing rod 403 to rotate around the cross bar 401 under the extrusion of the wind shield assembly 2. A silicone buffer head is installed at the end of the pressing rod 403. When the wind shield plate 201 is flipped and opened, the abutting rack 207 will continuously contact the pressing rod 403. By pressing the abutting rack 207 with the pressing rod 403, the wind shield plate 201 generates vibration, thereby vibrating off the sundries attached to the wind shield assembly 2. Each time the wind shield assembly 2 is opened and closed, the dust on its surface can be cleaned to avoid excessive accumulation of sundries and dust affecting the sealing effect after the wind shield assembly 2 is completely sealed.

[0038] In a further embodiment of the present invention, a sleeve 405 is rotatably sleeved at the end of the cross bar 401. One end of the sleeve 405 is fixedly connected with a driven gear ring 406. On one side of the wind deflector 201, a sector-shaped abutting tooth 210 meshing with the bottom of the driven gear ring 406 is fixedly connected. The other end of the sleeve 405 is coaxially sleeved with a sleeve 408 through a bushing 409. A slider is fixedly connected to the inner wall of the sleeve 408. A chute matching the slider is horizontally opened on the outer side of the sleeve 405. A top spring 410 is installed between the sleeve 408 and the bushing 409. A pressing tooth 411 is fixedly connected to the end face of the sleeve 408. The other end of the connecting frame 402 is symmetrically installed and sleeved on the bushing 409 on the cross bar 401. A torsion spring 412 is installed between the bushing 409 and the cross bar 401. An abutting block 413 in abutting cooperation with the pressing tooth 411 is fixedly connected to the end face of the bushing 409. Specifically, when the wind deflector 201 rotates and opens, the sector-shaped abutting tooth 210 drives the driven gear ring 406 and the sleeve 405 to rotate synchronously, so that the pressing tooth 411 of the sleeve 408 pushes the abutting block 413 on the bushing 409, and the acting force generated by the rotation of the sleeve 408 of the sleeve 405 is transmitted to the connecting frame 402 through the collision of the pressing tooth 411 and the abutting block 413, causing the connecting frame 402 and the pressure rod 403 to vibrate at a high frequency. The top spring 410 can not only push the sleeve 408 to axially displace on the sleeve 405, so that the pressing tooth 411 meshes with the abutting block 413, but also contract and store energy when the pressing tooth 411 and the abutting block 413 are pressed together, so as to quickly impact the connecting frame 402 through the pressing tooth 411, and make the pressure rod 403 impact the wind deflector 201 at a high frequency through the connecting frame 402, realizing further vibration for impurity removal. At the same time, the torsion spring 412 in the shaft can ensure that the connecting frame 402 drives the pressure rod 403 to continuously abut against the wind deflector 201. After the wind deflector 201 is closed, a radial component force is generated on the wedge-shaped inclined surface of the pressing tooth 411 and the abutting block 413, and a locking pre-tightening force is applied to the sleeve 408 through the top spring 410, improving the anti-airflow impact stability of the wind deflector 201 in the sealed state.

[0039] In a further embodiment of the present invention, a sealing strip 204 is provided at the edge of the wind deflector 201. The pressure rod 403 simultaneously presses against the sealing strip 204 and the wind deflector 201. Arc-shaped abutting grooves 205 are respectively formed on the wind deflector 201 and the sealing strip 204 with axially coincident positions. On one side of the inner wall of the limit accommodating groove 102, an anti-deviation docking groove 103 is formed. Both the arc-shaped abutting groove 205 and the anti-deviation docking groove 103 are matched with the pressure rod 403. When the wind deflector 201 is fully opened, the pressure rod 403 enters the arc-shaped abutting groove 205 and the anti-deviation docking groove 103. Specifically, the sealing strip 204 made of silica gel is embedded at the edge of the wind deflector 201. Arc-shaped abutting grooves 205 with the same center and the same radian are respectively formed at the connection between the sealing strip 204 and the wind deflector 201. The arc-shaped abutting groove 205 is matched with the pressure rod 403. The silica gel buffer head of the pressure rod 403 is set to be spherical, and its diameter is slightly smaller than the width of the arc-shaped abutting groove 205 to ensure that the pressure rod 403 can be embedded into the groove. The anti-deviation docking groove 103 is machined on one side of the inner wall of the limit accommodating groove 102 close to the ventilation opening 101, and its depth is the same as that of the arc-shaped abutting groove 205. The axes of the anti-deviation docking groove 103 and the arc-shaped docking groove coincide when the wind deflector 201 is fully opened. When the wind deflector 201 rotates to the maximum opening degree, the pressure rod 403 simultaneously enters the arc-shaped abutting grooves 205 of the wind deflector 201 and the sealing strip 204 and the anti-deviation docking groove 103 of the limit accommodating groove 102 to form a multi-point positioning structure. When the wind deflector 201 is opened, the pressure rod 403 is driven by the torsion spring 412 of the elastic pressing member 4 to continuously press against the surface of the wind deflector 201 and the sealing strip 204, and the attached substances are removed by high-frequency impact. When the wind deflector 201 is fully opened to the limit position, the buffer head of the pressure rod 403 is embedded into the overlapping groove body of the arc-shaped abutting groove 205 and the anti-deviation docking groove 103, thereby locking the position of the wind deflector 201 to prevent the yaw vibration caused by the air flow impact. And if there is a dislocation between the sealing strip 204 and the wind deflector 201, the axes between the arc-shaped abutting groove 205 on the wind deflector 201 and the arc-shaped abutting groove 205 on the sealing strip 204 deviate, which will cause the pressure rod 403 to be unable to enter the arc-shaped abutting grooves 205 on the sealing strip 204 and the wind deflector 201 completely. If the axis of the elastic pressing member deviates, the pressure rod 403 therein cannot enter the arc-shaped abutting groove 205 and the anti-deviation docking groove 103. At this time, the windshield assembly 2 cannot be fully opened. By observing the air volume, the problem can be quickly found to facilitate subsequent maintenance and replacement. At the same time, the contact surface between the arc-shaped abutting groove 205 of the sealing strip 204 and the pressure rod 403 forms an additional friction interface to further reduce the noise. During the closing process, the pressure rod 403 disengages from the anti-deviation docking groove 103, and the elastic pressing member 4 pushes the pressure rod 403 to tightly press against the sealing strip 204 through the pre-tightening force of the torsion spring 412 to ensure the firm connection between the wind deflector 201 and the sealing strip 204 in the closed state and stabilize the sealing performance.

[0040] In a further embodiment of the present invention, a closing anti-loosening member 6 is rotatably installed on one side of the shell 1, and one end of the closing anti-loosening member 6 is drivingly connected to one of the windshield components 2. When the windshield component 2 is closed, the friction between the closing anti-loosening member 6 and the windshield component 2 increases. At this time, the other windshield component 2 is closed and plugged into the closing anti-loosening member 6. Specifically, when one windshield component 2 is flipped and closed, the closing anti-loosening member 6 will be driven during the flipping process to increase the friction between it and the windshield component 2. When the windshield component 2 is completely closed, the friction between the closing anti-loosening member 6 and the windshield component 2 is maximum, so that the friction force on the axial direction of the windshield component 2 is significantly increased, thereby suppressing vibration loosening in the closed state. At the same time, the plug-in component on the other windshield component 2 can be plug-in-matched with the closing anti-loosening member 6 to form an axial limit, thereby preventing the two windshield components 2 from accidentally opening due to airflow impact or vibration. This design ensures the stability of the windshield component 2 during alternating wind guide and the entire closing process through a dual anti-loosening mechanism of friction self-locking and mechanical plug-in, while avoiding interference problems caused by the simultaneous closure of the two windshield components 2.

[0041] In a further embodiment of the present invention, the closing anti-loosening member 6 includes a connecting shaft 601 that passes through one side of the shell 1, the connecting shaft 601 is located between the two windshield components 2, the central shaft 202 is fixedly connected to a fan-shaped transmission tooth 206 on one side of the windshield plate 201, one end of the connecting shaft 601 is fixedly connected to a driven gear 603 that meshes with the fan-shaped transmission tooth 206, and the other end of the connecting shaft 601 is fixedly connected to a cam 604, and an elastic band 605 that abuts against a raised portion of the cam 604 is sleeved between the two cranks 203. Specifically, when a certain windshield component 2 is closed, its central shaft 202 drives the fan-shaped transmission tooth 206 to rotate, driving the driven gear 603 and the connecting shaft 601 to rotate, so that the raised portion of the cam 604 squeezes the inner side of the elastic band 605, forcing The elastic band 605 is deformed and holds each crank 203 on the two windshield components 2, thereby increasing the friction resistance of the crank 203 and playing a role in preventing loosening and slipping. The gear and cam 604 are linked with the elastic elastic band 605 to achieve adaptive friction anti-loosening in the closed state, ensuring high stability when the single-sided windshield component 2 is closed, while reducing the risk of mechanical interference. The design uses a dual anti-loosening mechanism of gear transmission and elastic compression of the cam 604 and elastic band 605 to dynamically adjust the friction resistance between the crank 203 and the track groove 302 when the windshield component 2 is closed, thereby preventing loosening caused by airflow impact and avoiding motion interference caused by locking the two windshield components 2 at the same time. The elastic deformation of the elastic band 605 can adaptively compensate for the wear gap of parts and extend the service life.

[0042] In a further embodiment of the present invention, a contact disk 606 is fixedly connected to the end face of the driven gear 603. A slot 607 for inserting another windshield assembly 2 is fixedly installed on the outer peripheral surface of the contact disk 606. A plug-in member 7 is installed on the windshield assembly 2. When the convex part of the cam 604 drives by the connecting shaft rod 601 abuts against the inner wall of the elastic band 605, the notch of the slot 607 is on the moving path of the plug-in member 7. Specifically, when one of the windshield assemblies 2 moves in a closing motion to drive the driven gear 603 to rotate, the connecting shaft rod 601 drives the cam 604 to squeeze the elastic band 605 under the rotation of the driven gear 603, increasing the frictional resistance of the crank 203. At the same time, the contact disk 606 on the driven gear 603 rotates synchronously, so that the slot 607 accurately aligns with the moving path of the plug-in member 7 on the other windshield assembly 2. When the other windshield assembly 2 closes, its plug-in member 7 rotates with the crank 203 and inserts into the slot 607 of the contact disk 606 to form a mechanical plug-in lock, preventing the two closed windshield assemblies 2 from loosening due to vibration or air flow impact. The clamping force of the elastic band 605 further inhibits the offset of the rotating shaft, ensuring that after the air distributor is completely closed, the channel will not be pushed open by some residual air flow, and the structural stability is strong. When the windshield assembly 2 is opened, the cam 604 disengages from the elastic band 605, and the contact disk 606 rotates in the reverse direction to disengage the slot 607 from the plug-in member 7, ensuring the freedom of movement and realizing the coordinated control of double anti-loosening in the fully closed state and zero interference in the open state.

[0043] In a further embodiment of the present invention, a contact spring 208 is installed in the arc contact groove 205 inside the sealing strip 204. The end of the contact spring 208 is fixedly connected to a top cover 209. When the pressure rod 403 enters the arc contact groove 205, the end of the pressure rod 403 abuts and cooperates with the top cover 209. Specifically, when the pressure rod 403 is embedded in the arc contact groove 205 as the windshield plate 201 is opened, the end of the pressure rod 403 squeezes the top cover 209, forcing the contact spring 208 to be further compressed. The elastic force of the contact spring 208 dynamically adjusts the pressing force of the pressure rod 403 on the sealing strip 204, which not only enhances the positioning stability of the windshield plate 201, but also compensates for the wear gap of the sealing strip 204 through elastic deformation. During the closing process, the contact spring 208 pushes the top cover 209 to rebound, assisting the pressure rod 403 to quickly disengage from the contact groove. At the same time, the spring vibration drives the sealing strip 204 to vibrate slightly to remove the dust accumulated in the groove of the sealing strip 204. The top cover 209 is in flexible contact with the rod head of the pressure rod 403 connected to the contact spring 208, reducing the collision noise, and the elastic support structure can adapt to the air flow pressure fluctuation, avoiding the fatigue cracking of the sealing strip 204 caused by hard collision and significantly extending the sealing life.
