Description

Technical Field

[0001] The present invention belongs to the technical field of air guiding, and relates to a louver wind shielding section and its series connection body. In addition, the present invention also provides a connecting arm, an air conditioner wind shielding system, and an assembling method for the louver wind shielding section. Background Art

[0002] An air conditioner is an electrical appliance for regulating the indoor air temperature and has been widely used in people's daily lives. However, during the use of an air conditioner, it is found that when the air conditioner wind blows directly on the human body, it may easily cause diseases such as colds and air conditioner diseases. Therefore, people have invented an air conditioner wind deflector, a wind shielding device arranged at the air outlet of the air conditioner. The principle of the air conditioner wind deflector is to use the wind deflector to block or change the direction of the air conditioner's air outlet, thereby reducing or avoiding the direct blowing of the air conditioner wind and reducing the health risks brought by the air conditioner to the human body to a certain extent. However, it is undeniable that the air conditioner wind after being processed by the air conditioner wind deflector has a single wind direction, and since the length of the air conditioner wind deflector is pre-made, it cannot be adapted to air conditioners with different air outlet lengths, affecting the scope of use and resulting in a poor overall user experience. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the length of the air conditioner wind deflector cannot be adapted to air conditioners with different lengths. In addition, the air outlet direction of the air conditioner after being processed by the air conditioner wind deflector is relatively single. Generally speaking, when the air blown out by the air conditioner hits the air conditioner wind deflector, part of the air blown out by the air conditioner will become the rebound wind towards the air outlet direction of the air conditioner, while the remaining air blown out by the air conditioner will only be the refraction wind blown out along the edge direction of the wind deflector. The air blown out by the air conditioner finally felt by the air conditioner user is the refraction wind. The direction of this kind of wind is usually single and will only change with the rotation angle of the wind deflector. For this reason, the present invention provides a louver wind blocking section to block the air blown out from the air conditioner air outlet. The louver wind blocking section includes a support arm, a wind blocking blade rotatably connected to the support arm, and a linkage mechanism for driving the wind blocking blade to rotate synchronously. The louver wind blocking section is provided with an external connection end for connecting another support arm at least at the end of one end of the support arm. The louver wind blocking section of the present invention can be connected to another louver wind blocking section through the external connection end, and the wind blocking area of the louver wind blocking section can be adjusted. For example, for an air conditioner air outlet with a longer length, several such louver wind blocking sections can be used, while for an air conditioner air outlet with a shorter length, the number of the louver wind blocking sections used can be reduced. The louver wind blocking section further includes a power transmission end. The power transmission end is directly or indirectly connected to the linkage mechanism, or the power transmission end and the linkage mechanism are of an integral structure. The power transmission end is connected to or separated from the power transmission end on the other support arm. The external connection end includes an opening, and the power transmission end passes through the opening to be connected to the power transmission end on the other support arm. In addition, using the external connection end of the louver wind blocking section of the present invention to connect multiple louver wind blocking sections in series can also provide multiple air outlet directions for the air blown out by the air conditioner. Specifically, the wind blocking blades rotatably connected to the same support arm rotate synchronously under the action of the same linkage mechanism, and the air blown out by the air conditioner can form a single-direction air outlet under the action of the wind blocking blades. However, the wind blocking blades on multiple support arms are controlled by their respective linkage mechanisms. Therefore, after being connected in series with each other under the action of the external connection end, the wind blocking blades connected to different support arms can rotate different angles, thereby forming multiple-direction air outlets of the air conditioner.

[0067] This part is a detailed description of the invention content part.

[0068] The present invention provides a louver wind shield section for blocking the air flow from the air outlet of an air conditioner, which includes a support arm, a wind shield blade rotatably connected to the support arm, and a linkage mechanism for driving the wind shield blade to rotate synchronously. The louver wind shield section is provided with an external connection end for connecting to another support arm at least at the end of one end of the support arm. In the present invention, an external connection end for connecting to another support arm is added at the end of one end of the support arm. The user can place the louver wind shield section in a position facing the air outlet of the air conditioner. Usually, its length covers the entire air outlet of the air conditioner to ensure that all the air flow from the air conditioner passes through the louver wind shield section and exits outward. When encountering a longer air outlet of the air conditioner, the external connection ends of the support arms of the louver wind shield section can be used to connect multiple louver wind shield sections in series. Therefore, the louver wind shield section of the present invention further has a wider range of use. In specific use, the louver wind shield section can include multiple support arms rotatably connected to the wind shield blade, such as two side-by-side support arms. The side-by-side support arms respectively support both ends of the wind shield blade, which can provide a more uniform supporting force for the wind shield blade. However, in this case, when multiple louver wind shield sections need to be connected in series to adapt to a longer air outlet of the air conditioner, more series connection operations will be faced, which is more time-consuming and laborious. Therefore, the louver wind shield section of the present invention tends to be provided with one support arm. Connecting multiple louver wind shield sections in series by using the external connection end of the louver wind shield section of the present invention can also provide multiple air outlet directions for the air flow from the air conditioner. Specifically, the wind shield blades rotatably connected to the same support arm rotate synchronously under the action of the same linkage mechanism. The air flow from the air conditioner can form a single-direction air outlet under the action of the wind shield blade. The wind shield blades on multiple support arms are controlled by their respective linkage mechanisms. Therefore, after being connected in series with each other under the action of the external connection end, the wind shield blades connected to different support arms can rotate at different angles, thereby forming air flow from the air conditioner in multiple directions.

[0069] In most embodiments of the present invention, the louver wind shield section further includes a power transmission end. The power transmission end can be directly connected to the linkage mechanism, indirectly connected to the linkage mechanism, or even integrated with the linkage mechanism, so that the power transmission end can transmit the power from the linkage mechanism. The power transmission end is connected or separated from the power transmission end on another support arm, and the external connection end includes an opening. When the power transmission end needs to be connected to the power transmission end on the other support arm, the power transmission end passes through the opening and is connected to the power transmission end on the other support arm. When the power transmission end is connected to the power transmission end on the other support arm, the wind shield blades connected to different support arms can rotate synchronously. When the power transmission end is separated from the power transmission end on the other support arm, the wind shield blades connected to different support arms can rotate independently. Thus, for the louver wind shield section that simply adapts to different lengths of air outlets of air conditioners, the power transmission ends can be connected to each other, and for the louver wind shield section that needs to generate different air outlet directions of air conditioners, the power transmission ends can be separated from each other.

[0070] In some embodiments, the connection of the external connection end and the connection of the power transmission end are synchronous. For example, when the external connection end is connected to the other support arm, the power transmission end is connected to the power transmission end on the other support arm, so as to realize the synchronous rotation of all the windshield blades. When the external connection end is separated from the other support arm, the power transmission end is separated from the power transmission end on the other support arm.

[0071] In some embodiments, the connection of the external connection end and the connection of the power transmission end are asynchronous. For example, the external connection end is sequentially provided with a far connection position and a near connection position along the direction from the external connection end to the middle of the support arm. When the external connection end is connected to the other support arm at the far connection position, the power transmission end is separated from the power transmission end on the other support arm. When the external connection end is connected to the other support arm at the near connection position, the power transmission end is connected to the power transmission end on the other support arm. In this way, if the user hopes to realize the synchronous rotation of all the windshield blades, the external connection end is connected to the other support arm at the near connection position. If the user hopes to realize the independent rotation of the windshield blades on different support arms, the external connection end is connected to the other support arm at the far connection position. The operation is very simple.

[0072] As for the specific connection method, whether it is for the external connection end or the power transmission end, those skilled in the art can use common connection methods. Those skilled in the art also know what structures need to be set at their respective connection ends before connection, and apply these structures to the external connection end and the power transmission end. For example, a clamping connection or a magnetic attraction connection method can be selected for connection. Taking the clamping connection as an example, the external connection end can be provided with a clamping groove and / or a clamping block, and at least part of the clamping groove and the clamping block are matched. The specific operation is to first clamp the external connection end to the other support arm, and then clamp the power transmission end to the power transmission end on the other support arm. This requires two steps of operation. If a magnetic attraction connection is adopted, after the external connection end is magnetically attracted to the other support arm, the power transmission end can be automatically magnetically attracted to the power transmission end on the other support arm. Therefore, the present invention preferably adopts the magnetic attraction connection method. Of course, in some embodiments, since the power transmission end is a transmission gear, specifically, the connection method between the power transmission end and the power transmission end on the other support arm can also be a gear meshing connection.

[0073] As mentioned above, the power transmission end of the present invention can be indirectly connected to the linkage mechanism. In some embodiments, the power transmission end is one of a transmission gear, a transmission rod or a transmission rack. A rotating joint is provided between the support arm and the windshield blade. The rotating joint includes a rotating bearing and a rotating shaft on the rotating bearing. A gear meshing with the transmission gear or the transmission rack is provided on the rotating shaft. In another part of the embodiments, a rotating bar for connecting the transmission rod is provided on the rotating shaft, and the rotating bar is rotatably connected to the transmission rod.

[0074] As described above, the power transmission end of the present invention can also be directly connected to the linkage mechanism. In some embodiments, the power transmission end is a transmission gear, and the linkage mechanism is one of a linkage gear or a worm that meshes with the transmission gear. In some embodiments, the power transmission end is a transmission rod, and the linkage mechanism is one of a worm, a linkage rod, or a linkage rack that is connected to the transmission rod. As described above, the power transmission end and the linkage mechanism of the present invention can also be an integral structure. In some embodiments, the linkage mechanism is one of a worm, a linkage rod, and a linkage rack, and the power transmission end is located at the end of the linkage mechanism.

[0075] In some embodiments, the transmission gear is at least two mutually meshing transmission gear sets. Taking two mutually meshing transmission gear sets as an example, compared with the single transmission gear used in some embodiments, after the power transmission end meshes with the power transmission end on another support arm, the rotation directions of the rotating blades of the windshields on adjacent support arms are opposite.

[0076] The opening on the outer connection end of the support arm is usually always open, but it can also be in a closed state, which does not affect the connection between the power transmission end and the power transmission end on another support arm. At this time, the power transmission end is a transmission rod, the linkage mechanism is a worm connected to the transmission rod, and the transmission rod is provided with a magnet that attracts the transmission rod on another support arm through the closed opening.

[0077] The support arm of the present invention usually has a receiving space for accommodating the linkage mechanism inside, so as to obtain a louver windshield section with a smaller overall volume. A limiting block and a blocking wall are provided between the support arm and the linkage mechanism. When the linkage mechanism drives the windshield blade to rotate, the limiting block moves towards the blocking wall and is finally blocked by the blocking wall and stops moving, so that the linkage mechanism stops moving, controlling the rotation of the windshield blade within a certain rotation angle range. A special case is that the limiting block is located at the end of the linkage mechanism, and the blocking wall is arranged on the side of the support arm facing the end of the linkage mechanism. When the linkage mechanism drives the windshield blade to rotate, the linkage mechanism moves relative to the support arm, so that the end of the linkage mechanism is blocked by the side of the support arm facing the end of the linkage mechanism and stops moving. In some embodiments, a limiting block and a blocking wall are not provided between the support arm and the linkage mechanism, but a resisting surface is provided on both the upper and lower parts of the windshield blade. When the resisting surface on the lower part of the windshield blade rotates to the upper part of the adjacent windshield blade and abuts against the resisting surface on the upper part of the adjacent windshield blade, the rotation of the windshield blade relative to the support arm is prevented.

[0078] A rotating joint is provided between the support arm and the wind deflector blade of the present invention. The rotating joint includes a rotating bearing and a rotating shaft that rotates on the rotating bearing. The rotating shaft is connected to the wind deflector blade. As for the linkage mechanism, the present invention provides four main structures: For the first linkage mechanism, one side facing the rotating shaft is a rack, and the rotating shaft is provided with a gear matching the rack. Through the meshing of the rack and the gear, the linkage mechanism drives the wind deflector blade to rotate; for the second linkage mechanism, one side facing the rotating shaft is a worm, and the rotating shaft is provided with a gear matching the worm. Through the meshing of the worm and the gear, the linkage mechanism drives the wind deflector blade to rotate; for the third linkage mechanism, one side facing the rotating shaft is a linkage rod, and the rotating shaft is provided with a rotating bar connecting the linkage rod. The rotating bar is rotatably connected to the linkage rod, so that the linkage mechanism drives the wind deflector blade to rotate; the fourth linkage mechanism includes a linkage gear, the linkage gear is located between two adjacent rotating shafts, and the rotating shaft is provided with a gear matching the linkage gear. The rotation of the linkage gear can drive the wind deflector blade to rotate.

[0079] The louvered wind deflector section of the present invention can also be provided with a power input end that provides power for the wind deflector blade to rotate relative to the support arm through the linkage mechanism.

[0080] The present invention also provides three main structures: When one side of the linkage mechanism facing the power input end is a rack or a linkage gear, the first power input end is provided with a power gear or a power worm matching the rack or the linkage gear, and the rack is driven to move or the linkage gear is rotated through the power gear or the power worm; when one side of the linkage mechanism facing the power input end is a worm, the power input end is provided with a connecting shaft connected to the worm, and the worm is rotated through the connecting shaft; when one side of the linkage mechanism facing the power input end is a linkage rod, the power input end is provided with a push-pull bar connected to the linkage rod, and the linkage rod is driven to move through the push-pull bar. It should be noted that the structures on one side and the other side of the linkage mechanism can be different. For example, one side of the linkage mechanism is provided with a rack while the other side of the linkage mechanism is a linkage rod. Therefore, if it is necessary to connect to both sides of the linkage mechanism, the structures on both sides of the linkage mechanism need to be matched respectively. The power input end further includes an operating rod, and the operating rod is directly or indirectly connected to one of the power gear, the power worm, the connecting shaft, and the push-pull bar.

[0081] The present invention provides some specific connection methods for the operating rod. For example, when the side of the linkage mechanism facing the power input end is a rack or a linkage gear, one end of the operating rod is directly connected to the power gear, or a thread matching the power gear is provided at one end of the operating rod, or one end of the operating rod is directly or indirectly connected to one end of the power worm; when the side of the linkage mechanism facing the power input end is a worm, the operating rod is directly or indirectly connected to the connecting shaft; when the side of the linkage mechanism facing the power input end is a linkage rod, the push-pull bar is fixedly connected or rotatably connected to the linkage rod, the operating rod is connected to the push-pull bar, or the push-pull bar is rotatably connected to the linkage rod, or the power input end further includes a transmission gear located between the operating rod and the push-pull bar, the first transmission gear is connected to the push-pull bar, and a thread matching the first transmission gear is provided at one end of the operating rod.

[0082] The present invention also provides some specific connection methods when one end of the operating rod is indirectly connected to the power worm and the connecting shaft respectively. When one end of the operating rod is indirectly connected to the power worm, the power input end further includes a first bevel gear provided at one end of the operating rod and a second bevel gear provided at one end of the power worm, and the first bevel gear is connected to the second bevel gear in a mating manner; or; the power input end further includes a second transmission gear provided at one end of the power worm, and a thread matching the second transmission gear is provided at one end of the operating rod. When the operating rod is indirectly connected to the connecting shaft, the power input end further includes a third bevel gear provided at one end of the operating rod and a fourth bevel gear provided at one end of the worm, and the third bevel gear is connected to the fourth bevel gear in a mating manner; or; the power input end further includes a third transmission gear provided at one end of the worm, and a thread matching the third transmission gear is provided at one end of the operating rod.

[0083] In some embodiments, the operating rod is a driven operating rod extending towards the user direction of the louver windshield section, which is convenient for the user to manually control the rotation of the windshield blades. The rotation of the windshield blades can also be electrically controlled. For example, a motor is added to the power input end, and the motor is connected to the operating rod. In some embodiments, in addition to having an operating rod extending towards the user direction of the louver windshield section, the power input end further has a protruding portion provided at one end of the operating rod and located between the linkage mechanism and the support arm. The linkage mechanism and the support arm are both provided with a blocking surface for blocking the protruding portion, restricting the protruding portion between the linkage mechanism and the support arm, and preventing the operating rod from disengaging from the linkage mechanism and losing the direct or indirect control effect on the linkage mechanism. In some embodiments, the operating rod is provided at the end of one end of the louver windshield section and away from the windshield blades, or the operating rod can also be provided outside the rotation space of the windshield blades to prevent the windshield blades from hitting the operating rod when rotating.

[0084] For the louvered windshield section using the power input end, there is no need for other louvered windshields to output power to the linkage mechanism through the power transmission end. Therefore, in some embodiments, the opening is in a closed state or the opening is provided with a switch for closing or opening the opening. By closing or sealing the opening, the power source of the linkage mechanism is separated from the power input end. Such a louvered windshields section can ensure independent control of the rotation of the windshield blades without being affected by the outside world. When external control of the rotation of the windshield blades is required, the opening can be opened.

[0085] In addition, in most embodiments of the present invention, the length direction of the support arm in the louvered windshields section is the same as the length direction of the air outlet of the air conditioner. In this way, when facing air conditioner air outlets of different lengths, generally only the support arms of different lengths need to be replaced, and there is no need to replace the entire windshield structure. The originally used windshield blades can still be used, and the replacement cost can be greatly reduced.

[0086] The support arm is also provided with an external connection position for fixing the support arm opposite to the air outlet of the air conditioner. The external connection position includes one of a slide rail, a slider, or a mounting position. By using a hanger hanging on the air conditioner and selecting a structure matching the slide rail, the slider, or the mounting position, the support arm can be fixed in a position opposite to the air outlet of the air conditioner. Those skilled in the art can select the connection point between the hanger and the support arm, and this connection point can obviously be fixed or can vary by sliding along the slide rail.

[0087] Although a single louvered windshields section can be used alone as long as its length is basically the same as the length of the air outlet of the air conditioner, more commonly, the length of a single louvered windshields section is shorter than the length of the air outlet of the air conditioner. For this reason, the present invention also provides a series connection body of louvered windshields sections. In some embodiments, the series connection body of louvered windshields sections is the first series connection body. The first series connection body includes at least two louvered windshields sections connected in series with each other through an external connection end. None of the louvered windshields sections are provided with a power input end. The first series connection body can extend the windshield area for synchronously rotating the windshield blades. In some embodiments, the louvered windshields section is the second series connection body. The second series connection body includes at least two louvered windshields sections connected in series with each other through an external connection end, and at least one of the louvered windshields sections is provided with a power input end. For example, in one case, the second series connection body has only one louvered windshields section provided with a power input end, and all the louvered windshields sections can be driven by the power input end to drive the windshield blades to rotate, so that all the windshield blades rotate synchronously. In another case, all the louvered windshields sections in the second series connection body are provided with power input ends, and the windshield blades in each louvered windshields section rotate independently, so that air can be blown out from the air conditioner in multiple directions.

[0088] Considering the series body formed by directly connecting the louver windshields in series, the connection firmness cannot be guaranteed. In some embodiments, connection fasteners are added to the series body of the louver windshields. At least two adjacent louver windshields are connected by the connection fasteners. The external connection end is connected to the adjacent support arm through the connection fastener. The connection fastener is a connection sleeve that at least partially sleeves the external connection end or a plug that at least partially inserts into the external connection end. In some embodiments, the connection fastener is provided with a channel for the power transmission end that first passes through the opening to pass through and be connected to the power transmission end on the adjacent support arm. In some embodiments, the connection between the external connection end and the connection fastener and the connection of the power transmission end are synchronous. For example, when the external connection end is connected to the connection fastener, the power transmission end passing through the channel is connected to the power transmission end on the adjacent support arm. In other embodiments, the connection between the external connection end and the connection fastener and the connection of the power transmission end are not synchronous. For example, the external connection end is sequentially provided with a far connection position and a near connection position along the direction from the external connection end to the middle of the support arm. When both sides of the connection fastener are connected to the external connection end at the far connection position, the power transmission end is separated from the power transmission end on the adjacent support arm. When at least one side of the connection fastener is connected to the external connection end at the near connection position, the power transmission end passing through the channel is connected to the power transmission end on the adjacent support arm. In this way, if the user hopes to achieve synchronous rotation of all the windshield blades in the series body of the louver windshields, then connect at least one side of the connection fastener to the external connection end at the near connection position. If the user hopes to achieve independent rotation of the windshield blades on different support arms, then connect both sides of the connection fastener to the external connection end at the far connection position, and the operation is very simple.

[0089] Different from the channel setting, a transfer linkage mechanism is provided in the connecting fastener in some embodiments. The transfer linkage mechanism is for the power transmission end passing through the opening to connect and is connected to the power transmission end on the adjacent support arm through the transfer linkage mechanism. In some embodiments, the connection between the external connection end and the connecting fastener is synchronous with the connection of the power transmission end. For example, when the external connection end is connected to the connecting fastener, the power transmission end passing through the opening is connected to the transfer linkage mechanism. In other embodiments, the connection between the external connection end and the connecting fastener is not synchronous with the connection of the power transmission end. For example, the external connection end is sequentially provided with a far connection position and a near connection position along the direction from the external connection end to the middle of the support arm. When both sides of the connecting fastener are connected to the external connection end at the far connection position, the power transmission end is separated from the transfer linkage mechanism. When at least one side of the connecting fastener is connected to the external connection end at the near connection position, the power transmission end passing through the opening is connected to the transfer linkage mechanism. In this way, if the user hopes to achieve synchronous rotation of all the wind-shielding blades in the series body of the louver wind-shielding section, then connect at least one side of the connecting fastener to the external connection end at the near connection position. If the user hopes to achieve independent rotation of the wind-shielding blades on different support arms, then connect both sides of the connecting fastener to the external connection end at the far connection position. The operation is also very simple.

[0090] As for the specific transfer linkage mechanism, it can be determined according to the specific form of the power transmission end. As mentioned above, the power transmission end can be one of a transmission gear, a transmission rod or a transmission rack. The transfer linkage mechanism is a transfer rod connected to the transmission rod or the transmission rack or a transfer gear meshing with the transmission gear. Referring to the foregoing, the external connection end and the connecting fastener can also adopt snap connection or magnetic attraction connection. The specific connection structure can refer to the foregoing. The present invention also preferably adopts magnetic attraction connection. Similarly, referring to the foregoing, the power transmission end and the power transmission end on the adjacent support arm can also adopt snap connection or magnetic attraction connection. The power transmission end and the transfer linkage mechanism can also adopt snap connection or magnetic attraction connection. The specific connection structure can refer to the foregoing. The present invention also preferably adopts magnetic attraction connection.

[0091] Referring to the foregoing, for the series body of the louver wind-shielding section, a connection fastener can also be provided with an external connection position for fixing the connection fastener at a position where the louver wind-shielding section faces the air outlet of the air conditioner. The external connection position includes one of a slide rail, a slider or a mounting position. By using a hanger hanging on the air conditioner and selecting a structure matching the slide rail, the slider or the mounting position, the connection fastener can be fixed at a position where the louver wind-shielding section faces the air outlet of the air conditioner.

[0092] The present invention also provides a connecting arm, which is used to extend the support arm in the louver wind-shielding section but is not connected to the wind-shielding blades, so as to cope with the usage scenarios where a longer louver wind-shielding section is required but more wind-shielding areas are not needed. The connecting arm is connected to the outer connecting end of the support arm. In some embodiments, the connecting arm is provided with a channel through which the power transmission end passing through the opening passes and is connected to the power transmission end on the other support arm. In other embodiments, the connecting arm is provided with a transfer linkage mechanism, and the transfer linkage mechanism is connected to the power transmission end passing through the opening and is connected to the power transmission end on the other support arm through the transfer linkage mechanism. Specifically, the power transmission end is one of a transmission gear, a transmission rod or a transmission rack, and the transfer linkage mechanism is a transfer rod connected to the transmission rod or the transmission rack or a transfer gear meshing with the transmission gear.

[0093] In some embodiments, at least one end of the connecting arm has the same structure as the outer connecting end of the support arm, so that after the connecting arm is connected to the support arm, it still has the same outer connecting end as the original support arm, and thus can be smoothly connected to the other support arm. Of course, when implementing the connecting arm, those skilled in the art can also refer to the connecting fasteners described above.

[0094] The present invention also particularly provides an air-conditioning wind-shielding system, which includes at least two air-conditioning air outlets arranged in series. There is a closed part for closing the air-conditioning air outlet between two adjacent air-conditioning air outlets. The system also includes a series body of louver wind-shielding sections, and the series body includes a blank section without connected wind-shielding blades and a wind-shielding section with connected wind-shielding blades. The length of the blank section is the same as that of the closed part and faces the closed part, and the wind-shielding section faces the air-conditioning air outlet. Obviously, the blank section can include the part of the support arm without connected wind-shielding blades and / or the connecting fasteners. The system can ensure that no wind-shielding facilities are configured at the closed part without air-conditioning air outlet, so that the wind-shielding utilization rate of the series body of louver wind-shielding sections is the highest.

[0095] Embodiment 1

[0096] See Figure 1 , this embodiment provides a louver wind-shielding section. Figure 1Shows the structure at one end of the louver wind shield section, including a support arm 5, a wind shield blade 1 and a linkage mechanism. A rotating shaft 9 extends from the middle of the wind shield blade 1 towards the support arm. A rotating bearing 3 is provided at the corresponding position of the support arm 5 and the rotating shaft 9. The rotating shaft 9 is inserted into the rotating bearing 3 to form a rotating joint. To facilitate the installation and removal of the rotating shaft 9 on the rotating bearing 3, a slideway 10 for the rotating shaft 9 to slide into the rotating bearing hole is provided on the rotating bearing 3. One side of the coupling mechanism facing the wind shield blade 1 is a rack 7. A receiving space 4 for accommodating the linkage mechanism is provided inside the support arm 5. A gear 2 matching the rack 7 is arranged on the rotating shaft 9. The reciprocating movement of the rack 7 in the receiving space 4 inside the support arm 5 can drive the wind shield blade 1 to rotate relative to the support arm 5 through the gear 2. The reciprocating movement of the linkage mechanism in the receiving space 4 is restricted. One of the reasons is to ensure that the rotation angle of the wind shield blade 1 relative to the support arm 5 is within a certain range, such as 0° - 180°, 30° - 120°, etc. Therefore, in this embodiment, a blocking wall 6 is provided on the linkage mechanism, and a limiting block 8 is provided inside the support arm 5. The reciprocating movement of the linkage mechanism in the receiving space 4 is limited by the movement of the limiting block 8 relative to the blocking wall 6, that is, when the blocking wall 6 blocks the limiting block 8, the linkage mechanism stops moving.

[0097] As a replacement for the louver wind shield section described in this embodiment, the distance between the two wind shield blades 1 is relatively short, for example, less than the width of the wind shield blade 1. A resisting surface 22 is provided on the upper part of the wind shield blade 1, and a resisting surface 21 is provided on the lower part of the wind shield blade 1. When the resisting surface 21 at the lower part of the wind shield blade abuts against the resisting surface 22 at the upper part of the wind shield blade, the rotation of the wind shield blade can be stopped. In this way, the functions of the limiting block 8 and the blocking wall 6 can be replaced. However, the limiting block 8 and the blocking wall 6 can set the rotation angle of the wind shield blade 1 within any rotation range, and only need to adjust the maximum distance between the limiting block 8 and the blocking wall 6. To prevent the linkage mechanism from disengaging from the receiving space, a blocking block is provided at the top of the limiting block 8, and the blocking block blocks the linkage mechanism to make the linkage mechanism move in the receiving space. A special blocking block is a cover plate covering the receiving space.

[0098] As another replacement for the louver wind shield section described in this embodiment, a limiting block 24 is provided at the end of the linkage mechanism, and a blocking wall 23 is provided on the surface of the support arm facing the end of the linkage mechanism. When the blocking wall 23 abuts against the limiting block 24, the linkage mechanism can stop moving.

[0099] See Figure 2 , Figure 2 In Figure 1On the basis of the above, the power input end is additionally shown. The louver wind shield section further includes a power input end, and the power input end includes an operating rod 16 for manual operation by the user. Since the side of the linkage mechanism facing the connection of the power input end is not a rack but a linkage rod 25, the linkage mechanism is a linkage rod relative to the power input end. The linkage rod 25 is provided with a connection groove 18, and the power input end further includes a push-pull bar 17 inserted into the connection groove 18. The push-pull bar 17 can push and pull the linkage rod 25. The linkage rod 25 and the push-pull bar 17 are rotatably connected through the connection groove 18, and the push-pull bar 17 is fixedly connected to the operating rod 16.

[0100] See Figure 3 , Figure 3 shows another power input end different from Figure 2 . The side of the linkage mechanism facing the connection of the power input end is a rack 19, and the power input end includes a power gear 20 for driving the rack 19 to move.

[0101] See Figure 4 , Figure 4 is Figure 3 a comparison diagram of the structure before and after assembly. The left side of the diagram shows the structure before assembly, and the right side shows the structure after assembly. The diagram shows a protruding portion 28 located at the end of the operating rod and protruding outward relative to the end of the operating rod as a whole. The support arm is provided with a blocking surface 26 for blocking the protruding portion 28, and the linkage mechanism is provided with a blocking surface 27 for blocking the protruding portion 28. During assembly, first pass a part of the operating rod through the space surrounded by the blocking surface 26, and block the operating rod through the protruding portion 28. Then install the linkage mechanism, and use the blocking surfaces 26 and 27 to limit the movement space of the protruding portion 28 to prevent the operating rod from detaching from the linkage mechanism.

[0102] Embodiment 2

[0103] See Figure 5 , Figure 5 shows another structure at one end of the louver wind shield section. The louver wind shield section is partially the same as that in Embodiment 1, for example, both include a support arm and a wind shield blade 29. A gear 32 is provided on the rotating shaft of the wind shield blade 29. The main difference is that the linkage mechanism is a linkage gear 30, and the linkage gear 30 is located between two adjacent rotating shafts. One end of the operating rod is provided with a gear 31 that meshes with both the gear 32 and the linkage gear 30.

[0104] Embodiment 3

[0105] See Figure 6 , Figure 6 shows another structure at one end of the louver wind shield section. The louver wind shield section is the same as Figure 5The structures are generally the same. For example, a connection slot 34 is provided on one side of the linkage mechanism facing the power output end. The power input end further includes an operating rod and a push-pull bar 35 inserted into the connection slot 34 and rotatably connected to the connection slot 34. The main difference is that the power input end further includes a gear 37 and a runner 35. The push-pull bar 35 is fixed on the gear 37 through the runner 36. One end of the operating rod is provided with a thread meshing with the gear 37. Rotating the operating rod can indirectly push and pull the push-pull bar 35 to drive the linkage mechanism.

[0106] Embodiment 4

[0107] See Figure 7 , Figure 7 shows the structure of one end of another louver windshield section. The louver windshields of Embodiment 1 Figure 1 The louver windshields are partially the same. The main difference is that the linkage mechanism is a power worm 39. The power input end includes a connecting shaft connected to the power worm 39 and an operating rod. A gear 40 is provided on the connecting shaft. One end of the operating rod is provided with a thread 41 meshing with the gear 40. Rotating the operating rod can drive the power worm 39 to rotate. As an improvement of this embodiment, the gear 40 is a bevel gear. Another bevel gear matching the bevel gear is provided at one end of the operating rod. The operating rod controls the rotation of the worm 39 through the bevel gear set.

[0108] Embodiment 5

[0109] See Figure 8 , Figure 8 shows the structure of one end of another louver windshields. The louver windshields are the same as those of Figure 6 The basic structures are generally the same. The main difference is that a rotating bar 42 is provided on the rotating shaft connected to the windshield blade. A connection slot 43 for inserting the rotating bar 42 is provided on the side of the linkage mechanism facing the windshield blade. The rotating bar 42 and the linkage mechanism are rotatably connected through the connection slot 43. The movement of the linkage mechanism can drive the windshield blade to rotate through the rotating bar 42 inserted into the connection slot 43.

[0110] Embodiment 6

[0111] This embodiment shows the structure of connecting two louver windshields described in Embodiment 1 in series. See Figure 9 , Figure 9 shows the louver windshields described in Embodiment 1 Figure 1 The structure of the other end opposite to the shown end before they are connected to each other (only the support arm part is shown). An external connection end is provided at the end of the support arm 5. A card slot 11 is provided at the external connection end of some support arms 5, and a card block 12 is provided at the external connection end of some support arms 5. When the card block 12 is inserted into the card slot 11, the series connection of the two louver windshields can be completed. Of course, those skilled in the art can also perform operations on Figure 1 the shown end of the support arm asFigure 9 The modification of the end of the support part enables both ends of the support arms in the louver windshield section described in Embodiment 1 to be serially connected to other support arms. The slot 11 and the block 12 can also be magnets, and the two are magnetically connected.

[0112] Embodiment 7

[0113] See Figure 10 , on the basis of Embodiment 6, this embodiment additionally shows a linkage mechanism and a power transmission end. The linkage mechanism is a rack 62, and the power transmission end is a transmission rod 60. The support arm is provided with an opening 61 for the transmission rod 60 to pass through. The support arm is connected to another support arm through an external connection end. The transmission rod 60 can pass through the opening 61 and be connected to the transmission rod 63 on another support arm. In this embodiment, the above two connections are not synchronized. As Figure 10 shown, although the two support arms are already connected to each other, the transmission rod 60 is not connected to the transmission rod 63. The transmission rod 61 is provided with a block, and the transmission rod 63 is provided with a slot. The user needs to connect the two after the two support arms are connected to each other. Figure 11 This embodiment is improved, that is, a magnet 64 is provided on the transmission rod. When the two support arms are connected to each other, the two transmission rods are also connected to each other through the magnet 64. Therefore, the connection of the support arm to another support arm through the external connection end is synchronized with the connection of the transmission rod to another transmission rod.

[0114] Embodiment 8

[0115] See Figure 12 , this figure shows that the power transmission end in this embodiment can be a transmission gear 65. The gear 66 is connected to the rotating shaft of the windshield blade. The linkage mechanism is a linkage gear 67. Different from the integral structure or connection mode of the transmission rod and the rack described in Embodiment 7, the transmission gear 65 described in this embodiment meshes with the gear 66 and does not directly mesh with the linkage gear 67. The external connection end of the support arm is also provided with an opening 68 for the transmission gear 65 to pass through. Specifically, part of the teeth of the transmission gear 65 pass through the opening 68 and are exposed outward so as to mesh with the transmission gears on other support arms. That is, as described in Embodiment 7, when the external connection end of the support arm is connected to the other support arm, the transmission gear 65 meshes with the transmission gears on the other support arms. Of course, an improvement of this embodiment is to replace the transmission gear 65 with a transmission gear set, and the effect can be seen in the relevant content of the specific implementation manner.

[0116] Embodiment 9

[0117] See Figure 13, this embodiment shows a structure different from the structure in which the two louver windshields described in Embodiment 6 are connected in series as described in Embodiment 1. The main difference is that a far connection position 69 and a near connection position 70 are sequentially arranged along the outer end of the support arm towards the middle of the support arm, and a linkage mechanism and a power transmission end are added. The linkage mechanism is a worm 71, and the power transmission end is a transmission rod 72 connected to the worm 71. A corresponding transmission rod 73 is also arranged on the other support arm. Only the transmission rod 72 has a plug, while the transmission rod 73 has a groove. In Figure 13 In the described state, the support arm and the other support arm are clamped at the far connection position 69. At this time, the transmission rod 72 and the transmission rod 73 are still in a separated state, and in Figure 14 In the described state, the support arm and the other support arm are clamped at the near connection position 70. At this time, the transmission rod 72 and the transmission rod 73 are clamped. Therefore, the user can intuitively know whether the transmission rods are connected to each other through different connection positions.

[0118] Embodiment 10

[0119] See Figure 15 , Embodiment 10 is in exactly the same state as in Embodiment 9. The difference is that the transmission rod 74 is provided with a magnet, and the opening 75 through which the transmission rod 74 passes is Figure 13 open in Figure 15 , but it can actually be closed. After closing, the transmission rod 74 can still be magnetically attracted to each other through the opening by the magnet. Of course, it is also possible to set a switch on the opening 75, which does not affect the magnetic attraction connection of the transmission rod 74.

[0120] Embodiment 11

[0121] Embodiment 8 shows that the transmission gear does not mesh with the linkage mechanism, but meshes with the gear arranged on the rotation shaft of the windshield blade. Regarding the various structures on the rotation shaft of the windshield blade, this embodiment refers to the various structures described in Embodiments 1-5, and correspondingly replaces the transmission gear with a transmission rod or a transmission rack.

[0122] Embodiment 12

[0123] See Figure 16 , this embodiment provides a simple series connection body of louver windshields. The series connection body includes two louver windshields and a connecting fastener 14. Complex series connection bodies often include at least three or more louver windshields. In fact, Figure 10 - 11 , Figure 13 - 15 has already partially shown the series connection body of the louver windshields. The support arms of this part of the series connection body are directly connected to each other, while the series connection body of the louver windshields described in this embodiment adds a connecting fastener 14 between the two louver windshields. The connecting fastener 14 can at least strengthen the connection strength of the two louver windshields. For Figure 16The external connection end of the support arm shown does not have an obvious external connection structure by itself, such as the clamping structure mentioned above, but magnets can be provided, or two support arms can be connected in series with the help of the connecting member 14, which can also play the role of external connection.

[0124] See Figure 16 , only an opening 13 for the power transmission end to pass through is provided at the external connection end of the support arm 5. The connecting fastener 14 is a connecting sleeve, and both ends respectively sleeve the external connection end of the support arm 5, so as to connect two support arms in series. A channel 15 is provided in the connecting member 14, and the power transmission end passing through the opening 13 is connected to the power transmission end on another support arm 5 through the channel 15. The specific structure of the power transmission end can refer to the foregoing embodiments. When both sides of the connecting fastener are clamped (or magnetically connected) to the external connection end of the support arm, the power transmission ends on the support arm are connected to each other. The louver windshield section can be selected to have a power input end or not. In this way, the series body composed entirely of louver windshields without a power input end only simply extends the windshield range and cannot rotate the windshield blades. However, after being connected in series with the series body of the louver windshields with at least one power input end, the windshield blades can be rotated to achieve the windshield effect. The specific structure of the power input end can refer to the foregoing embodiments. The specific structure inside the support arm is not shown in this embodiment. In fact, multiple power input ends can be provided on the series body. Then, the windshield area controlled by the louver windshields with power input ends has the ability to independently control the windshield direction.

[0125] Embodiment 13

[0126] See Figure 17 , this embodiment provides a special series body of louver windshields. The series body of louver windshields uses two Figure 12The described louver windshield section and the connecting fastener 46 sleeved on the outer ends of the support arms of two louver windshields. An opening 45 is provided at the outer end of the support arm of the louver windshield section. The transmission gear 44 adjacent to the opening 45 passes through the opening 45, and the teeth of part of the transmission gear 44 pass through the opening 45 and engage with the transmission gear on the other support arm through the channel of the connecting fastener 46. The connecting fastener is provided with a clamping hole 49 and a clamping hole 48 that are clamped with the clamping head 47 at the outer end of the support arm. The outer end of the support arm is provided with a far connection position at the clamping head 47 and a near connection position at 76. When the clamping head 47 is clamped with the clamping hole 48, the outer end of the support arm is connected to the connecting fastener 46 at the far connection position. At this time, the transmission gears 44 are separated, so that all the windshields of the series body of the louver windshield section cannot rotate synchronously, but the windshields on the two support arms rotate synchronously independently. When the clamping head 47 is clamped with the clamping hole 49, the outer end of the support arm is connected to the connecting fastener 46 at the near connection position 76. At this time, the transmission gears 44 are engaged with each other. Thus, all the windshields of the series body of the louver windshield end can rotate synchronously.

[0127] Embodiment 14

[0128] This embodiment separately shows the support arm, see Figure 18 , this figure shows that an installation position 50 is provided on one side of the support arm, and this installation position can fix the support arm at a position facing the air outlet of the air conditioner.

[0129] Embodiment 15

[0130] See Figure 19 , this embodiment is an improvement on Embodiment 13. The main difference is that a transfer linkage gear 53 is provided in the connecting fastener 52 and there is no longer a channel. When the outer end of the support arm is connected to the connecting fastener 52 and is at the near connection position 78, among the two outer ends of the support arms connected by the connecting fastener 52, the transmission gears 51 and 54 adjacent to the opening are both engaged with the transfer linkage gear 53. Thus, all the windshields of the series body of the louver windshield section can rotate synchronously in the same direction.
