These ventilation windows are equipped with vents and movable baffles, which are flipped to control the opening and closing of the vents. In order to cope with rainy weather and prevent rain from entering when the ventilation windows are open, waterproof structures such as waterproof blinds are added inside the ventilation windows. While waterproof blinds block rain, they can also ensure ventilation to a certain extent. However, in non-rainy weather, waterproof blinds may hinder the ventilation effect of the ventilation windows.

Ensuring that the heat dissipation ventilation windows of energy storage equipment are effectively waterproof in rainy weather while avoiding the negative impact of waterproof structures such as waterproof shutters on the ventilation effect in non-rainy weather has become a key technical issue that needs to be solved in the current field of energy storage equipment heat dissipation design.

[0038] The following is combined with Figure 1-11 This application is described in further detail. Example 1
[0039] The present application discloses a ventilation window. Figure 1 and Figure 2 The ventilation window includes a housing 1, and the housing 1 is used to be installed on the target device. The housing 1 is provided with an air duct 11 for heat exchange between the inside and outside of the target device. The side of the housing 1 located outside the target device is recorded as the outer side, and the side of the housing 1 facing the inside of the target device is recorded as the inner side. A baffle 12 is hinged on the outer side of the housing 1, and the baffle 12 can be flipped to block the air duct 11 and achieve a sealing effect on the air duct 11. The hinge axis of the baffle 12 is located above the air duct 11. When the baffle 12 is opened, the baffle 12 blocks the top of the air duct 11, which can play a rain-proof effect and reduce the situation where rainwater enters the fan.
[0040] In order to further improve the waterproof effect of the ventilation window, the housing 1 is further provided with waterproof shutters 13, and when the baffle 12 is closed, the waterproof shutters 13 are located between the baffle 12 and the air duct 11. After the baffle 12 is opened, the waterproof shutters 13 still cover the air duct 11, reducing the situation where the lateral wind blows rainwater into the air duct 11. However, the provision of the waterproof shutters 13 to block the air duct 11 will also affect the ventilation effect of the air duct 11, and to a certain extent affect the heat dissipation effect of the entire target device.
[0041] like Figure 3 and Figure 4 In the embodiment of the present application, the waterproof shutter 13 is hinged on the housing 1, and the hinge axis of the waterproof shutter 13 on the housing 1 is parallel to the hinge axis of the baffle 12 on the housing 1. A push rod 14 is movably arranged inside the housing 1, and a control device 15 for driving the push rod 14 to move is arranged inside the housing 1. The push rod 14 is connected to the baffle 12 through the first connection structure 2, and the push rod 14 is connected to the waterproof shutter 13 through the second connection structure 3.
[0042] In the embodiment of the present application, the push rod 14 is slidably disposed in the housing 1 along its own axial direction, and the axis of the push rod 14 is perpendicular to the hinge axis of the baffle 12 and the waterproof shutter 13 on the housing 1.
[0043] The control device 15 can be a screw nut mechanism driven by a motor, a pulley mechanism driven by a motor, or a gear 7 rack 71 mechanism driven by an electric cylinder 16. The driving component in the embodiment of the present application is an electric cylinder 16, which is fixedly installed in the housing 1, and the piston rod of the electric cylinder 16 is connected to the push rod 14. The operator controls the extension and retraction of the piston rod of the electric cylinder 16 to drive the push rod 14 to move axially.
[0044] like Figure 5 and Figure 6The electric cylinder 16 is connected to the push rod 14 through a linkage 17. The linkage 17 includes a guide shaft 18 fixedly connected to the housing 1. The central axis of the guide shaft 18 is colinear with the central axis of the push rod 14. The push rod 14 is provided with a guide groove for inserting the guide shaft 18. The push rod 14 is slidably arranged in the housing 1 through the guide shaft 18, and the push rod 14 is fixedly connected to the piston rod of the electric cylinder 16.
[0045] The first connection structure 2 includes a first sleeve 21, a first crank 22 and a first rotating shaft 23. The first rotating shaft 23 is fixedly connected to the baffle 12 and extends into the housing 1. The baffle 12 is hinged to the housing 1 through the first rotating shaft 23. The first crank 22 is located in the housing 1 and fixedly connected to the first rotating shaft 23. A first waist-shaped hole 24 is formed on the first crank 22. The length direction of the first waist-shaped hole 24 is parallel to the radial direction of the cross section of the first rotating shaft 23. The first sleeve 21 is sleeved on the push rod 14, and a first insertion rod 25 for inserting into the first waist-shaped hole 24 is fixedly connected to the first sleeve 21.
[0046] The first sleeve 21 is slidably sleeved on the push rod 14, and the push rod 14 is fixedly connected with a first limiting ring 27 and a second limiting ring 28, the first limiting ring 27 is located above the second limiting ring 28, and the first sleeve 21 is located between the first limiting ring 27 and the second limiting ring 28. In the embodiment of the present application, a first elastic member 29 is arranged on the push rod 14 between the first limiting ring 27 and the first sleeve 21, and the first elastic member 29 pushes the first sleeve 21 toward pressing against the second push rod 14. The first elastic member 29 in the embodiment of the present application is a spring.
[0047] When the baffle 12 is in the closed state, the end of the first crank 22 away from the first rotating shaft 23 tilts upward, and the push rod 14 is in the lifted state. When the baffle 12 is opened, the electric cylinder 16 starts to drive the push rod 14 downward, and under the linkage of the first plug rod 25 and the first waist-shaped hole 24, the first crank 22 is driven to flip downward, and then the baffle 12 is driven to flip to the open state through the first rotating shaft 23. In this process, the first elastic member 29 always pushes the first sleeve 21 to press against the second limit ring 28. At this time, the first spring has a buffering effect. When the baffle 12 is subjected to a downward external force, the baffle 12 can overcome the elastic force of the first elastic member 29 and flip downward to achieve a buffering effect, which is conducive to improving the service life of the baffle 12.
[0048] A first limit seat 8 is provided in the casing 1, and two first support surfaces 81 are provided on the first limit seat 8 for limiting the flipping angle of the first crank 22. When the baffle 12 is in an open state, the first crank 22 abuts against one of the first support surfaces 81, and when the baffle 12 is in a closed state, the first crank 22 abuts against the other first support surface 81.
[0049] The second connection structure 3 includes a second sleeve 31, a second crank 32 and a second shaft 33. The second shaft 33 is fixedly connected to the waterproof shutter 13 and extends into the housing 1. The waterproof shutter 13 is hinged to the housing 1 through the second shaft 33. The second crank 32 is located in the housing 1 and fixedly connected to the second shaft 33. A second waist-shaped hole 34 is formed on the second crank 32. The length direction of the second waist-shaped hole 34 is parallel to the radial direction of the cross section of the second shaft 33. The second sleeve 31 is sleeved on the push rod 14, and a second insertion rod 35 is fixedly connected to the second sleeve 31 and is used to be inserted into the second waist-shaped hole 34.
[0050] When the waterproof shutter 13 is closed, the end of the second crank 32 away from the second rotating shaft 33 is tilted upward, and when the waterproof shutter 13 is opened, the end of the second crank 32 away from the second rotating shaft 33 is tilted downward. A second limit seat 83 is provided in the housing 1, and two second support surfaces 84 for limiting the flip angle of the second crank 32 are provided on the second limit seat 83. When the baffle 12 is in the open state, the second crank 32 abuts against one of the second support surfaces 84, and when the baffle 12 is in the closed state, the second crank 32 abuts against the other second support surface 84.
[0051] A first retaining ring 37 and a second retaining ring 38 are fixedly connected to the push rod 14 below the second limiting ring 28, the first retaining ring 37 is located above the second retaining ring 38, and the second sleeve 31 is located between the first retaining ring 37 and the second retaining ring 38. In the embodiment of the present application, a second elastic member 39 is provided on the push rod 14 between the second retaining ring 38 and the first sleeve 21, and the second elastic member 39 pushes the second sleeve 31 so that the end of the second crank 32 away from the second rotating shaft 33 remains in an inclined upward state. In this state, the waterproof shutter 13 is closed. The second elastic member 39 in the embodiment of the present application is a spring.
[0052] During the gradual opening of the baffle 12, the push rod 14 needs to gradually move downward, during which the first elastic member 29 pushes the first sleeve 21 to press against the second limiting ring 28, while the first retaining ring 37 is always located above the second sleeve 31 and does not contact the second sleeve 31. The second elastic member 39 opens, and its elastic potential energy decreases.
[0053] After the baffle 12 is fully opened, the push rod 14 continues to move downward, the first baffle ring 37 gradually approaches the second sleeve 31, and pushes the second sleeve 31 to move downward, and then the second crank 32 flips downward, so that the waterproof shutter 13 can be gradually opened. In this process, the first elastic member 29 is compressed, and its elastic potential energy increases; the second elastic member 39 continues to open, and its elastic potential energy decreases.
[0054] In order to improve the stability of the waterproof shutter 13 in the closed state and reduce the possibility of accidental opening thereof. In the embodiment of the present application, a connecting rod 4 is rotatably arranged in the housing 1, and the connecting rod 4 is used to support the second sleeve 31 and limit the second sleeve 31 from moving downward to prevent the waterproof shutter 13 from unfolding. The connecting rod 4 is provided with a first guide rail 41 and a second guide rail 42, and the first guide rail 41 and the second guide rail 42 are interconnected. The guide rod 43 is used to be in the first guide rail 41 or the second guide rail 42. When the guide rod 43 is in the first guide rail 41, the connecting rod 4 is supported on the side of the second sleeve 31 away from the first retaining ring 37. When the guide rod 43 is in the second guide rail 42, the connecting rod 4 releases the supporting and limiting effect on the second sleeve 31.
[0055] In the process of the baffle 12 moving from closed to fully open, the first baffle ring 37 moves downward with the push rod 14 but never contacts the upper surface of the second sleeve 31, and the guide rod 43 is always located in the first guide rail 41 during the process and moves toward the second guide rail 42. If the push rod 14 stops moving at this time, the baffle 12 is in the open state, while the waterproof shutter 13 is in the closed state, and the connecting rod 4 abuts against the lower surface of the second sleeve 31 to limit the waterproof shutter 13 from turning over.
[0056] If the push rod 14 continues to move downward, before the first stop ring 37 contacts the second sleeve 31, the guide rod 43 gradually moves from the first guide rail 41 to the second guide rail 42. When the first stop ring 37 contacts the second sleeve 31, the guide rod 43 is located in the second guide rail 42, the connecting rod 4 completes the flip, and the supporting and limiting effect on the second sleeve 31 is released.
[0057] As the push rod 14 continues to move downward, the first retaining ring 37 pushes the second sleeve 31 downward and drives the second crank 32 to flip, thereby driving the waterproof shutter 13 to gradually open until it is fully opened, thereby making the baffle 12 and the waterproof shutter 13 both in an open state.
[0058] The operator can control the moving distance of the push rod 14 to control the baffle 12 to open alone, or control the baffle 12 and the waterproof shutter 13 to open, so as to adapt to different environmental requirements. Example 2
[0059] like Figure 7 and Figure 8 The difference between this embodiment 2 and embodiment 1 is that the push rod 14 is rotatably connected to the casing 1, the first rotating shaft 23 is still fixed on the baffle 12, and is rotatably connected to the casing 1 through the first rotating shaft 23, the second rotating shaft 33 is still fixed on the waterproof louver 13, and is rotatably connected to the casing 1 through the second rotating shaft 33, and the rotation axis of the push rod 14 is parallel to the rotation axis of the first rotating shaft 23 and the second rotating shaft 33.
[0060] like Fig. 9 and Fig.10 The first connection structure 2 includes a first groove wheel 5 fixedly connected to the first rotating shaft 23 coaxially, and a first radial groove 51 and a first driven locking arc 52 are provided on the first groove wheel 5, and the first driven locking arc 52 is recessed on the circumferential surface of the first groove wheel 5. A first active dial 53 is rotatably connected to the housing 1 through a push rod 14, and a first cylindrical pin 54 and a first active locking arc 55 are provided on the first active dial 53, wherein the first cylindrical pin 54 is used to cooperate with the first radial groove 51, the central axis of the first active locking arc 55 is colinear with the rotation axis of the first active dial 53, and the first active locking arc 55 is used to cooperate with the first driven locking arc 52. The electric cylinder 16 is connected to the first active dial 53 through a linkage 17 to drive the first active dial 53 to rotate.
[0061] The linkage member 17 can be driven by the gear 7 and the rack 71, or by a pulley, or by the crank connecting rod 4. In the embodiment of the present application, the linkage member 17 includes a gear 7 coaxially fixedly connected to the push rod 14, and a rack 71 is provided on the piston rod of the electric cylinder 16 at a position corresponding to the gear 7, and the gear 7 and the rack 71 are meshed with each other. When the piston rod of the electric cylinder 16 moves, the rack 71 is driven to move, and under the transmission action of the gear 7 and the rack 71, the gear 7 drives the first active dial 53 to rotate.
[0062] Two first driven locking arcs 52 are provided on the first groove wheel 5 , and the two first driven locking arcs 52 are symmetrically arranged about the first cylindrical pin 54 .
[0063] When the baffle 12 is closed, the first active locking arc 55 of the first active dial 53 cooperates with one of the first driven locking arcs 52 to limit the first shaft 23 and the baffle 12 from turning over. At this time, the first cylindrical pin 54 and the first radial groove 51 are separated from each other.
[0064] During the process of opening the baffle 12, the first active dial 53 rotates, so that the first cylindrical pin 54 gradually approaches and inserts into the first radial groove 51, and at the same time, the first active locking arc 55 gradually separates from the original first driven locking arc 52. When the first cylindrical pin 54 is inserted into the first radial groove 51, the first active locking arc 55 just separates from the first driven locking arc 52. As the first active dial 53 continues to rotate, the first cylindrical pin 54 pushes the groove wall of the first radial groove 51 to drive the first rotating shaft 23 and the baffle 12 to rotate.
[0065] When the baffle 12 is fully opened, the first active locking arc 55 enters into the other first driven locking arc 52, and the first cylindrical pin 54 is separated from the first radial groove 51. The first active dial 53 continues to rotate, so that the first active locking arc 55 is concavely matched with the first driven locking arc 52, and the baffle 12 remains in the open state.
[0066] The second connection structure 3 in the embodiment of the present application has the same structure as the first connection structure 2, and the second connection structure 3 includes a second groove wheel 6 fixedly connected to the second rotating shaft 33 coaxially, and the second groove wheel 6 is provided with a second radial groove 61 and a second driven locking arc 62, and the second driven locking arc 62 is recessed on the circumferential surface of the second groove wheel 6. A second active dial 63 is rotatably connected in the housing 1, and a second cylindrical pin 64 and a second active locking arc 65 are provided on the second active dial 63, wherein the second cylindrical pin 64 is used for sliding cooperation with the second radial groove 61, the central axis of the second active locking arc 65 is colinear with the rotation axis of the second active dial 63, and the second active locking arc 65 is used for concave-convex cooperation with the second driven locking arc 62. There are two second driven locking arcs 62 on the second groove wheel 6, and the two second driven locking arcs 62 are symmetrically arranged about the second cylindrical pin 64.
[0067] The first active dial 53 and the second active dial 63 may be coaxially fixedly connected to the same push rod 14 , or may be separately fixed to different push rods 14 . In the embodiment of the present application, the first active dial 53 and the second active dial 63 are coaxially fixedly connected to the same push rod 14 .
[0068] like Fig. 9 , Fig.10 as well as Fig.11 , the process of the baffle 12 from the closed state to the fully open state is as follows: State a: the first active locking arc 55 first cooperates with one of the first driven locking arcs 52, and the first cylindrical pin 54 is arranged away from the first radial groove 51; State b: As the first active dial 53 rotates, the first active locking arc 55 gradually moves away from the original first driven locking arc 52, and the first cylindrical pin 54 gradually inserts into the first radial groove 51, driving the first groove wheel 5, the first rotating shaft 23 and the baffle 12 to rotate; State c: With the continued rotation of the first active dial 53 , until the first active locking arc 55 cooperates with the other first driven locking arc 52 , the first cylindrical pin 54 is disengaged from the first radial groove 51 again.
[0069] State ac: During the process of the baffle 12 changing from the closed state to the fully opened state, the waterproof shutter 13 is always in the closed state, and although the second active dial 63 rotates synchronously with the first active dial 53, the second active locking arc 65 always cooperates with one of the second driven locking arcs 62 to limit the rotation of the baffle 12. At the same time, the second active locking arc 65 gradually separates from the second driven locking arc 62, and the second cylindrical pin 64 gradually moves toward the second radial groove 61.
[0070] After the baffle 12 is fully opened, the second active dial 63 and the first active dial 53 continue to rotate synchronously, and the process is as follows: State d: The first active locking arc 55 always cooperates with the subsequent first driven locking arc 52, and the second active locking arc 65 is separated from the second driven locking arc 62, and the second cylindrical pin 64 pushes the groove wall of the second radial groove 61 to drive the second rotating shaft 33 to rotate, so that the waterproof shutter 13 gradually opens.
[0071] State e: When the waterproof shutter 13 is fully opened, the second cylindrical pin 64 is again separated from the second radial groove 61, and the second active locking arc 65 cooperates with another second driven locking arc 62. At this time, the first active locking arc still maintains a cooperative state with the subsequent first driven locking arc 52. The baffle 12 and the waterproof shutter 13 are both in the open state.
[0072] In summary, the baffle 12 and waterproof shutter 13 of the ventilation window can be pushed by the push rod 14 from closed to open in the following three states: the baffle 12 and waterproof shutter 13 are both closed, the baffle 12 is open and the waterproof shutter 13 is closed, and the baffle 12 and waterproof shutter 13 are both open. The operator can control the ventilation window to be in any of the above states by controlling the extension distance of the piston rod of the electric cylinder 16 to adapt to different environmental requirements.
[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
