Description

Technical Field

[0001] This utility model relates to the field of window opener technology, and in particular to a novel concealed electric window opener. Background Technology

[0002] With the continuous development of modern architectural design concepts, people have placed higher demands on the comfort, intelligence, and aesthetics of their living and working environments. As an important component of the building envelope, windows are gradually evolving from traditional manual operation to electric and intelligent mechanisms. Electric window openers, due to their ease of operation and remote control capabilities, are finding increasingly widespread use in smart homes and modern buildings.

[0003] However, some existing electric window openers still have unresolved issues in practical applications. Currently, electric window openers on the market often prioritize electric opening and closing functions in their structural design, but their operability is severely limited in emergencies such as power outages. Once a power outage occurs, the window cannot be opened or closed electrically, causing considerable inconvenience to users. If users forcibly push or pull the window manually, the rigid connection between the motor and transmission mechanism may reverse the motor's rotation, damaging the motor and its reduction gear. This affects the reliability and user experience of the electric window opener. Furthermore, many electric window openers have their mechanical structures or drive components exposed after installation, which conflicts with the modern architectural trend towards simplicity and integration, affecting the overall visual effect. Additionally, some electric window openers lack an effective automatic locking mechanism when the window is fully open. In the event of strong winds or other external forces, the window may unexpectedly spring back or close, posing a safety hazard.

[0004] Therefore, this utility model proposes a novel concealed electric window opener to solve the problems of existing electric window openers, such as the inability to operate manually during power outages, the risk of motor damage, and the lack of consideration for automatic locking function and concealed aesthetic requirements. Utility Model Content

[0005] In view of the problems of existing novel concealed electric window openers, such as inability to be manually operated during power outages, lack of automatic locking function when the window is fully opened, resulting in inconvenience and low reliability, this utility model aims to provide a novel concealed electric window opener with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a novel concealed electric window opener, comprising: a window body and a window sill installed on the window body; a fixing mechanism, the fixing mechanism including a fixing block one fixed to the wall and a fixing block two moving with the window body; a conversion mechanism, the conversion mechanism being housed inside the window sill, the conversion mechanism including a motor, the output end of the motor being connected to a gear engagement device; the fixing mechanism further including a limiting corner block and an L-shaped block, the conversion mechanism further including a gear engagement device two that can engage or disengage with the gear engagement device one, and a fork-shaped connecting rod.

[0007] The fixing mechanism further includes a fixing column fixed to the fixing block two and extending toward the fixing block one.

[0008] Furthermore, the limiting corner block and the L-shaped block are rotatably connected to the fixing block one, and the fork-shaped connecting rod is used to drive the engagement device two to rise and fall so that it separates from or engages with the engagement device one. The engagement device two is driven to connect to the window. The electric and manual modes are switched through the action of the fork-shaped connecting rod, and the automatic locking of the window when it is opened is achieved through the cooperation of the fixing column with the limiting corner block and the L-shaped block.

[0009] Preferably, the conversion mechanism further includes a support block, and the fork-shaped connecting rod uses the support block as a fulcrum to drive the gear engagement device to rise and fall in a lever-like manner.

[0010] Preferably, the conversion mechanism further includes a disc and a limiting disc, the disc and the limiting disc being stacked sequentially above the second gear engagement device, and the fork-shaped connecting rod acting on the limiting disc to lift the limiting disc, the disc and the second gear engagement device.

[0011] Preferably, the conversion mechanism further includes a spring that acts between the fork-shaped connecting rod and the limiting plate to apply a restoring force to the fork-shaped connecting rod.

[0012] Preferably, the conversion mechanism further includes a limiting component, which includes a fixedly disposed groove and a limiting block connected to the fork-shaped link. The limiting block can slide within the groove to limit the stroke of the fork-shaped link.

[0013] Preferably, the fixing post has a locked position in which the fixing post has passed the limiting corner block and the L-shaped block and is blocked by the falling and reset limiting corner block and the L-shaped block to restrict the closing movement of the window.

[0014] Preferably, the shape and structure of the L-shaped block are adapted to be lifted by an external force so as to remove it from the obstruction of the fixed column.

[0015] Preferably, an installation space for accommodating the fixing mechanism is pre-set between the wall and the window.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that electric window openers cannot be manually opened during power failure and that forced operation can easily damage the motor by setting up a switching mechanism for the engagement and disengagement of the gears controlled by a fork-type connecting rod. It achieves the technical effect of easily switching to manual mode in the event of a power failure, which is convenient to use and effectively protects the motor, thereby improving the practicality and reliability of the product.

[0017] 2. This utility model solves the problem in the prior art that the window is not locked after it is opened to the maximum position, and is easily closed accidentally by external force, which poses a safety hazard. It achieves the technical effect of automatically locking the window when it is opened to the maximum position, effectively preventing accidental closure, improving the safety of use, and avoiding impact damage to the window opener itself.

[0018] 3. This utility model solves the problem of exposed structure of existing electric window openers, which affects the overall aesthetics of the window and wall, by cleverly incorporating the conversion mechanism inside the window sill and setting the fixing mechanism in the hidden space between the wall and the window. It achieves the overall hidden installation of the device, without damaging the original appearance of the building, and makes the window opener and the window integrated, thus meeting the technical effect of modern buildings' pursuit of simplicity and beauty.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Example: Please refer to Figures 1 to 5 This utility model provides a novel concealed electric window opener, which aims to solve the problems of existing concealed electric window openers being unable to be manually operated during power outages and lacking an effective automatic locking structure when opened to the maximum position.

[0023] like Figure 1 As shown, the new type of concealed electric window opener is applied between wall 1 and window 2. It includes a window 2 and a window sill 3 installed on the window 2. The main structure of the device includes a conversion mechanism 4 and a fixing mechanism 5. The conversion mechanism 4 is fully housed inside the window sill 3 to achieve concealed installation. The fixing mechanism 5 is set in the pre-set installation space between wall 1 and window 2. The fixing mechanism 5 includes a fixing block 1 51 fixedly connected to wall 1 and a fixing block 2 54 that moves with window 2.

[0024] Specifically, the conversion mechanism 4 is the core component for switching between electric and manual modes, such as... Figure 3 As shown, the conversion mechanism 4 is equipped with a motor 41 as a power source. The output end of the motor 41 is fixedly connected to a gear engagement device 42. Above the gear engagement device 42, a gear engagement device 43 is also provided. The gear engagement device 43 can move up and down to engage or disengage with the gear engagement device 42. The gear engagement device 43 is driven to connect to the window 2 through a transmission mechanism (not shown). The conversion mechanism 4 also includes a fork-shaped linkage 47 for controlling mode switching. The fork-shaped linkage 47 drives the gear engagement device 43 to rise and fall, thereby controlling the disengagement or engagement of the gear engagement device 43 with the gear engagement device 42.

[0025] The fixing mechanism 5 is used to lock the form 2 in the opened position, such as... Figure 4 and Figure 5As shown, a limiting corner block 52 and an L-shaped block 53 are rotatably connected to a fixed block 1 51, and a fixed post 55 is fixedly connected to a fixed block 2 54. The fixed post 55 extends toward the fixed block 1 51, and it mechanically interferes with the limiting corner block 52 and the L-shaped block 53 during the opening of the window 2.

[0026] Reference Figure 3 and Figure 4 The conversion mechanism 4 has a support block 48 inside, and a fork-shaped connecting rod 47 is lever-mounted on the support block 48. It moves up and down with the support block 48 as the fulcrum. A disc 44 and a limiting disc 45 are stacked on top of the second gear engagement device 43. A part of the fork-shaped connecting rod 47 spans above the limiting disc 45. When the operating end of the fork-shaped connecting rod 47 is pressed, the fork-shaped connecting rod 47 uses the support block 48 as the fulcrum to lift the limiting disc 45, the disc 44 and the second gear engagement device 43 as a whole upwards, thereby completely separating the second gear engagement device 43 from the first gear engagement device 42 below and cutting off the power transmission of the motor 41. This lever-type separation structure ensures that the manual switching action is labor-saving and reliable.

[0027] To achieve automatic reset after mode switching, the conversion mechanism 4 also includes a spring 46. The spring 46 acts between the fork-shaped link 47 and the limiting plate 45 and continuously applies a reset force to the fork-shaped link 47. When the external pressing force disappears, the elastic force of the spring 46 will push the fork-shaped link 47 back to the initial position, thereby causing the second gear 43 to fall and re-engage with the first gear 42, restoring the electric mode.

[0028] To ensure the stability and accuracy of the movement of the fork-shaped link 47, the conversion mechanism 4 is also provided with a limiting component 49. The limiting component 49 includes a fixedly set groove 492 and a limiting block 491 fixedly connected to the fork-shaped link 47. The limiting block 491 can slide inside the groove 492. The contour of the groove 492 limits the movement stroke of the fork-shaped link 47 to prevent excessive displacement or movement interference.

[0029] Reference Figure 4 and Figure 5The structure of the fixing mechanism 5 has been further optimized. The fixing post 55 has a locking position. In the locking position, the main body of the fixing post 55 has passed the limiting corner block 52 and the L-shaped block 53 and is blocked by the side walls of the limiting corner block 52 and the L-shaped block 53 after falling and resetting. This structural blocking relationship restricts the movement of the window 2 in the closing direction, thereby achieving a stable lock. The shape and structure of the L-shaped block 53 are designed to be lifted by external force. Specifically, the L-shaped block 53 has an operating part that extends upward or outward. The operating part provides a convenient force point. When the window 2 needs to be closed, the user can lift the operating part to make the L-shaped block 53 rotate around its rotation connection point, thereby freeing it from the obstruction of the fixing post 55 and unlocking it. There is a pre-set installation space between the wall 1 and the window 2 to accommodate the fixing mechanism 5, so that the fixing mechanism 5 can be completely hidden in the gap between the wall and the window when the window 2 is closed, without affecting the overall aesthetics of the building.

[0030] The working principle is as follows: In the electric opening mode, the motor 41 starts and drives the window 2 to open through the meshing gear 1 42 and gear 2 43. As the window 2 moves, the fixing block 2 54 and fixing post 55 fixed on it move synchronously toward the fixing block 1 51 fixed to the wall 1. During the movement, the fixing post 55 pushes and lifts the limiting corner block 52 and L-shaped block 53 that are rotatably connected to the fixing block 1 51. When the window 2 is opened to the preset maximum position, the main body of the fixing post 55 completely passes over the limiting corner block 52 and L-shaped block 53. At this time, the limiting corner block 52 and L-shaped block 53 fall back to their original positions under the action of gravity and block behind the fixing post 55, thereby forming a stable mechanical lock to prevent the window 2 from closing accidentally.

[0031] When switching to manual mode is required, such as in the event of a power outage, the operator presses the fork-shaped linkage 47. The fork-shaped linkage 47, using the support block 48 as a fulcrum, overcomes the elastic force of the spring 46 and pushes upward the limiting plate 45, the disc 44, and the second gear 43, thereby disengaging the engagement between the second gear 43 and the first gear 42. This cuts off the power transmission path between the motor 41 and the window 2. At this time, the window 2 can be manually opened or closed like a normal window, and the disengaged state protects the motor 41 from being driven in reverse. During the entire switching process, the limiting block 491 connected to the fork-shaped linkage 47 slides within the groove 492 of the limiting component 49, ensuring the precise travel of the switching action. When it is necessary to restore the electric mode, the pressure on the fork-shaped linkage 47 is released, and the restoring force of the spring 46 will drive all components to reset, causing the second gear 43 to re-engage with the first gear 42.
