Description

Technical Field

[0001] This utility model relates to the field of louver technology, and in particular to a louver opening and closing device and a power supply vehicle. Background Technology

[0002] Venetian blinds are used in various industries, such as in power supply vehicles. The core equipment of these vehicles is a diesel generator (or other power generation device), which generates a large amount of heat during operation and requires the intake of cool air to maintain combustion and dissipate heat. Simultaneously, it needs to prevent external environmental factors (dust, rain, debris) from entering the equipment compartment. Therefore, the venetian blinds on the power supply vehicle, acting as a "breathing passage" for the equipment compartment, are particularly important. With the upgrading of building technology and living needs, venetian blind opening and closing technology is gradually evolving from manual to automated and intelligent. In existing technologies, for example, the blades are connected by levers, ropes, or gear mechanisms, allowing direct manual operation. For instance, rotating a handle drives the blades to rotate, and pulling a rope achieves overall lifting and lowering. Another example is using an electric motor as a power source, with gearboxes, connecting rods, or synchronous belts to achieve blade rotation or overall lifting and lowering. However, these structures are not only complex, but also directly affect the opening and closing of the venetian blinds when there is insufficient power or mechanical failure, causing them to malfunction and significantly impacting the efficiency and safety of the power supply vehicle.

[0006] A louver includes a window frame and a slat assembly rotatably disposed within the window frame. The slat assembly includes multiple slats arranged along the length or width of the window frame. The window frame is used to be embedded in a mounting wall.

[0007] At least one transmission component, each of the transmission components being located on one side of the blade group, the transmission component including a connecting code and a plurality of transmission plates, one end of each transmission plate being rotatably connected to the window frame and fixedly connected to one of the blades, and the other end being rotatably connected to the connecting code;

[0009] The driving assembly further includes a driving source, which is disposed on the window frame or the mounting wall. The fixed slider has a groove, and the driving end of the driving source is provided with a driving pin. The driving pin is movably inserted through the groove. The driving source can drive the driving pin to abut against one end of the groove and push the fixed slider to overcome the elastic element, or drive the driving pin to move towards the other end of the groove, so that the fixed slider can be reset under the action of the elastic force.

[0010] The fixed slider can overcome the movement of the elastic element under the action of a manual external force applied thereto, the drive pin moves relative to the slide groove, and can be reset after the manual external force is removed.

[0011] As a preferred embodiment of a louver opening and closing device, the drive end of the drive source is provided with an extended shaft tube, and the end of the extended shaft tube opposite to the drive end of the drive source is provided with an axial mounting groove, the fixed slider is slidably disposed in the mounting groove, and the drive pin is connected in the mounting groove.

[0012] As a preferred embodiment of a louver opening and closing device, the drive assembly further includes a drive source mounting base, which is disposed on the window frame or the mounting wall, and the drive source is movably mounted on the drive source mounting base.

[0013] As a preferred embodiment of a louver opening and closing device, the elastic element includes a tension spring.

[0014] As a preferred embodiment of the louver opening and closing device, it also includes a manual pull cord, one end of which is connected to the fixed slider.

[0016] As a preferred embodiment of the louver opening and closing device, it also includes an air volume sensor, which is electrically connected to the drive source and is used to detect the air volume entering through the blade assembly.

[0017] In a preferred embodiment of a venetian blind opening and closing device, the transmission piece includes a first segment and a second segment, which form an angle with each other.

[0018] A power supply vehicle includes a carriage and the louver opening and closing device described in any of the above technical solutions, wherein the side wall of the carriage is the mounting wall.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model provides a louver opening and closing device, which includes a louver, at least one transmission component, and at least one drive component. A drive source pushes a fixed slider to move, thereby driving a connecting bracket and multiple transmission plates to move, achieving simultaneous rotation of multiple blades. When the drive source removes its driving force, the driving pin gradually reduces and eventually removes its pushing force on the fixed slider. The fixed slider automatically resets under the elastic force of the elastic element, thus achieving reverse rotation of the multiple blades. This electrically opens or closes the blade assembly, resulting in a high degree of automation, good controllability of the blade assembly's opening and closing degree, and convenience. When the drive source fails and the fixed slider cannot move, an external force is applied to the fixed slider, causing it to overcome the elastic element and move. Due to the groove design, the drive pin moves relative to the groove without interfering with the movement of the fixed slider, thereby driving the connecting bracket and multiple transmission plates to move, achieving simultaneous rotation of multiple blades. After the external force is removed, the fixed slider returns to its original position under the elastic force of the elastic element, realizing the directional rotation of the blade group. This allows for manual opening or closing of the blade group, effectively preventing the blade group from failing due to drive source failure, ensuring the normal operation of the louvers, and demonstrating good reliability. This louver opening and closing device has a high degree of integration, low structural complexity, and is easy to operate.

[0021] This utility model also provides a power supply vehicle. By adopting the above-mentioned louver opening and closing device, both electric and manual control of the louvers can be realized, reducing the failure rate of the louvers and improving the reliability of use.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0038] like Figures 1 to 6 As shown, this embodiment provides a louver 1 opening and closing device, which can be applied to a vehicle or wall, such as in the carriage of a power vehicle, to achieve ventilation or sealing of the interior space. The louver 1 opening and closing device includes a louver 1, at least one transmission component 2, and at least one drive component 3. The drive component 3 drives the transmission component 2 to move, thereby opening and closing the louver 1. The louver 1 includes a window frame 11 and a blade assembly rotatably disposed within the window frame 11. The blade assembly includes multiple blades 12 arranged along the length or width direction of the window frame 11. The window frame 11 is used to be embedded in a mounting wall, for example, the side wall of the power vehicle carriage is the mounting wall, and the window frame 11 is embedded in the side wall of the power vehicle carriage.

[0039] Specifically, each transmission assembly 2 is located on one side of the blade group. Each transmission assembly 2 includes a connecting code 21 and multiple transmission plates 22. Each transmission plate 2 corresponds one-to-one with multiple blades 12. One end of each transmission plate 22 is rotatably connected to the window frame 11 and fixedly connected to one blade 12, while the other end is rotatably connected to the connecting code 21. The connecting code 21 connects to the multiple transmission plates 22, meaning that the movement of the connecting code 21 drives the multiple transmission plates 22 to move synchronously, thereby driving the multiple blades 12 to move synchronously, realizing the opening and closing of the blade group. It should be noted that the blades 12 can be rotatably mounted on the window frame 11 via the transmission plates 22, or they can be directly rotatably mounted on the window frame 11 via a rotating shaft. Two transmission assemblies 2 can be provided, corresponding to both sides of the blade group respectively, to improve the control force on the blade group. Each transmission component 2 corresponds to at least one drive component 3. The drive component 3 includes a fixed slider 31 and an elastic element 32. The fixed slider 31 is connected to the corresponding connecting code 21 and is connected to the window frame 11 or mounting wall via the elastic element 32. The fixed slider 31 can be forced to overcome the movement of the elastic element 32, or can be reset under the elastic force of the elastic element 32, thereby driving the blade assembly to rotate through the transmission component 2, thus opening or closing the blade assembly. The drive components 3 can be two, three, or four, depending on actual needs. For example, in the initial state, when the blade assembly is closed, the fixed slider 31 is forced to overcome the movement of the elastic element 32, causing the elastic element 32 to store force and drive the blade assembly to rotate and open. After the force is removed, the elastic element 32 returns to its original position, driving the fixed slider 31 to reset, thereby closing the blade assembly.

[0040] Preferably, the elastic element 32 includes a tension spring, one end of which is mounted on the mounting wall or window frame 11 via a fixing seat, and the other end is hooked to the fixing slider 31. Of course, in other embodiments, the elastic element 32 can also be other structures, such as a rubber band.

[0041] More specifically, the transmission plate 22 includes a first segment and a second segment, which are at an angle to each other. The end of the first segment opposite to the second segment is rotatably connected to the window frame 11 and fixedly connected to a blade 12. The end of the second segment opposite to the first segment is rotatably connected to the connecting bracket 21. That is, the transmission plate 22 is non-linear, which helps to save installation space.

[0042] In this embodiment, as Figure 2 , Figure 4 and Figure 5As shown, the fixed slider 31 can be electrically driven, exhibiting a high degree of automation and excellent controllability of the opening and closing degree of the blade assembly, making it convenient and quick. Specifically, the drive assembly 3 also includes a drive source 33, which is mounted on the window frame 11 or the mounting wall. The fixed slider 31 has a groove 310, and the drive end of the drive source 33 is provided with a drive pin 34. The drive pin 34 movably passes through the groove 310. The drive source 33 can drive the drive pin 34 to abut against one end of the groove 310 and push the fixed slider 31 to move against the elastic element 32, or drive the drive pin 34 to move towards the other end of the groove 310, so that the fixed slider 31 moves and resets under the action of elastic force. The drive source 33 is a cylinder or a telescopic hydraulic cylinder, meaning the drive source 33 moves linearly. For example, multiple blades 12 are arranged along the height direction of the window frame 11. The downward movement of the connecting code 21 can drive the blade assembly to open. The groove 310 on the fixed slider 31 extends along the height direction. The tension spring is located above the fixed slider 31, and the drive source 33 is located above the fixed slider 31. When the drive end of the drive source 33 extends, the drive pin 34 abuts against the lower end of the groove 310 and pushes the fixed slider 31 downward, thereby driving the blade assembly to open. When the drive end of the drive source 33 retracts, the tension spring pulls the fixed slider 31 upward, thereby driving the blade assembly to close. It should be noted that "downward" refers to vertical downward and downward at a certain angle, with a general downward trend. The same applies to "upward".

[0043] More specifically, the drive assembly 3 also includes a drive source mounting base 36, which is disposed on the window frame 11 or the mounting wall, and the drive source 33 is movably mounted on the drive source mounting base 36. For example, a sleeve is rotatably disposed on the drive source mounting base 36, and the drive source 33 passes through the sleeve. During the process of the drive source 33 driving the fixed slider 31, the sleeve has a certain degree of freedom of movement, so that the drive source 33 has a degree of freedom of movement, allowing the drive source 33 to smoothly drive the fixed slider 31 and avoid jamming or other situations.

[0044] Preferably, such as Figure 3 As shown, the drive end of the drive source 33 is provided with an extended shaft tube 35. The end of the extended shaft tube 35 away from the drive end of the drive source 33 is provided with an installation groove 350 along its axial direction. The fixed slider 31 is slidably disposed in the installation groove 350, and the drive pin 34 is connected in the installation groove 350. This makes the relative position of the fixed slider 31 and the drive source 33 more stable, and also makes the cooperation between the drive pin 34 and the slide groove 310 more stable, avoiding situations such as disengagement or interference jamming.

[0045] In this embodiment, as Figure 2 and Figure 6As shown, the fixed slider 31 can also be manually driven. Under the action of a manual external force applied to it, the fixed slider 31 overcomes the elastic element 32, allowing the drive pin 34 to move relative to the slide groove 310. It can also reset itself after the manual external force is removed. When the drive source 33 fails, preventing the fixed slider 31 from moving, an external force is applied to the fixed slider 31, causing it to overcome the elastic element 32. Due to the slide groove 310, the drive pin 34 moves relative to the slide groove 310 without interfering with the movement of the fixed slider 31. This drives the connecting code 21 and multiple transmission plates 22 to move, enabling the simultaneous rotation of multiple blades 12. After the external force is removed, the fixed slider 31 resets itself under the elastic force of the elastic element 32, allowing the blade group to rotate in the direction of rotation. This allows for manual opening or closing of the blade group, effectively preventing the blade group from failing due to a drive source 33 failure, ensuring the normal operation of the louver 1, and demonstrating good reliability.

[0046] Preferably, the louver 1 opening and closing device further includes a manual pull cord 4, one end of which is connected to a fixed slider 31. Applying force to the manual pull cord 4 to pull the fixed slider 31 facilitates operation.

[0047] More preferably, the louver 1 opening and closing device also includes a manual throttle cable, with the other end of the manual pull rope 4 connected to the manual throttle cable. The manual throttle cable is a relatively mature existing technology, so it will not be described in detail here. The manual throttle cable facilitates operation by the operator and can lock the manual pull rope so that the fixed slider 31 stops at the expected position, thus ensuring that the slat assembly stops at the expected opening angle.

[0048] Furthermore, the louver 1 opening and closing device also includes an airflow sensor, which is electrically connected to the drive source 33. The airflow sensor is used to detect the airflow through the blade assembly. For example, the airflow sensor is installed in the passenger compartment to detect the ventilation situation inside the compartment. The drive source 33 operates according to the detection signal from the airflow sensor, such as by adjusting the extension or retraction length of the drive end, to control the opening angle of the blade assembly, thereby controlling the airflow.

[0049] This embodiment also provides a power supply vehicle, which includes a carriage and the aforementioned louver 1 opening and closing device, with the side wall of the carriage serving as the mounting wall. By employing the aforementioned louver 1 opening and closing device, both electric and manual control of the louver 1 can be achieved, reducing the failure rate of the louver 1 and improving its reliability.

[0050] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
