Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides a technical solution: a lift window, comprising: a lift window frame 1, a fixed window sash 2 fixedly installed in the lower part of the lift window frame 1, a lift window sash 3 slidably arranged in the lift window frame 1, and a lift assembly 5 installed on the top of the lift window frame 1, the lift assembly 5 being connected to the lift window sash 3;

[0027] Specifically, the lifting component 5 includes a motor, a reducer, a winding roller 51, and a sheet-like chain belt 52. The motor is connected to the winding roller 51 through the reducer. The sheet-like chain belt 52 is wound around the winding roller 51. The lower end of the sheet-like chain belt 52 is fixedly connected to the lifting window sash 3. The sheet-like chain belt 52 is made of metal. Driven by the motor and the reducer, the winding roller 51 winds or extends the sheet-like chain belt 52, so that the lifting window sash 3 can automatically rise and fall along the lifting window frame 1.

[0028] To ensure the safety of the lifting window sash 3 in a stalled state, the lifting window frame 1 is equipped with an electromagnetic lock 6 for emergency braking of the sheet chain belt 52, and the lifting window sash 3 is equipped with a mechanical lock 8 for emergency braking on the side.

[0029] Slider 7 is symmetrically fixedly installed on the side of the lifting window sash 3. The slider 7 is centrally located on the side of the lifting window sash 3 and is fixedly connected to the sheet-like chain belt 52.

[0030] The slider 7 is fixedly connected to the side of the extension arm 71. The extension arm 71 is equipped with a sensor 72 and a sliding conductive terminal 73. The sensors 72 on the left and right sides of the lifting window sash 3 are a speed sensor and an acceleration sensor, respectively, which are used to monitor in real time whether the lifting window sash 3 is in a stall state.

[0031] The sliding conductive terminal 73 cooperates with the conductive slide bar of the lifting window frame 1 to achieve real-time conductivity and power the electronic components on the lifting window sash 3.

[0032] When the lifting window sash 3 is detected to be in a stalled state, the electromagnetic lock 6 and the mechanical lock 8 are triggered simultaneously to perform emergency braking on the lifting window sash 3 and improve safety.

[0033] The electromagnetic lock 6 includes a fixed base 61, which is fixedly installed inside the lifting window frame 1. Four first guide rods 62 are installed on the fixed base 61. A fixed plate 63 and a sliding seat 64 are fixedly installed on the first guide rods 62. The fixed plate 63 and the sliding seat 64 are located on both sides of the sheet-like chain belt 52. Silicon steel sheets and iron plates 66 are installed at the edges of the fixed plate 63 and the sliding seat 64. The silicon steel sheets are made conductive, so that they generate a strong attraction with the iron plates, so that the fixed plate 63 and the sliding seat 64 clamp the sheet-like chain belt 52. A composite braking plate 65 is fixedly installed on the opposite side of the fixed plate 63 and the sliding seat 64. The composite braking plate 65 clamps the sheet-like chain belt 52 to perform emergency braking, so that the lifting window sash 3 stops rising and falling.

[0034] The fixed plate 63 and the sliding seat 64 are provided with torsion springs 67 on their sides. When the power is off, the torsion springs 67 reset and the fixed plate 63 and the sliding seat 64 separate.

[0035] The mechanical lock 8 works with the rack 9 to achieve emergency braking. The rack 9 is fixedly installed inside the lifting window frame 1. The mechanical lock 8 includes a toggle block 81, which is fixedly connected to the rotating arm 82. The middle part of the rotating arm 82 is rotatably connected to the lifting window sash 3. The other end of the rotating arm 82 is fixedly installed with a convex shaft 821. The convex shaft 821 is slidably connected to the inclined groove 831 on the guide slide 83. When the guide slide 83 moves up and down, the inclined groove 831 and the convex shaft 821 work together to make the rotating arm 82 rotate due to the lever action, thereby pushing the toggle block 81 to mesh with the rack 9, so that the lifting window sash 3 is fixed relative to the lifting window frame 1.

[0036] The upper and lower ends of the guide slide plate 83 are fixedly connected to the guide slide rod 86. The guide slide rod 86 is slidably connected to two guide seats 87. The guide seats 87 are fixedly installed on the side of the lifting window sash 3. A first spring 85 is sleeved on the guide slide rod 86 at the lower end of the guide slide plate 83. The lower end of the first spring 85 abuts against the lower guide seat 87. A sliding handle 84 is fixedly installed on the side of the guide slide plate 83. The sliding handle 84 slides along the frame of the lifting window sash 3. The guide slide plate 83 is driven to descend by the sliding handle 84. The first spring 85 is compressed. The rotating arm 82 rotates and drives the actuating tooth block 81 to disengage from the rack 9.

[0037] The lower end of the guide slide rod 86 is connected to the trigger assembly 88. Specifically, the lower end of the guide slide rod 86 is fixedly installed with a stop block 861. The trigger assembly 88 includes a drive motor 881, a baffle plate 882, a second spring 883, a second guide rod 884, and a moving rack 885. The moving rack 885 is fixedly connected to the baffle plate 882, and the baffle plate 882 is fixedly connected to the second guide rod 884. The second spring 883 is sleeved on the second guide rod 884. The second spring 883 provides elastic force to the baffle plate 882, so that it engages with the stop block 861, thereby limiting the stop block 861 and keeping the guide slide rod 86 in a fixed state.

[0038] The movable rack 885 is slidably connected to the lifting window sash 3. The drive motor 881 drives the connecting gear, which meshes with the movable rack 885. The drive motor 881 is fixedly installed on the side of the lifting window sash 3. By driving the gear to rotate through the drive motor 881, the movable rack 885 drives the baffle 882 to disengage from the baffle 861. At this time, the first spring 85 resets and pushes the guide slide 83 upward, triggering the engagement of the actuating tooth block 81 with the rack 9, thereby realizing the emergency braking of the lifting window frame 1 and the lifting window sash 3.

[0039] Working principle: The lifting component 5 drives the sheet chain 52, which in turn drives the lifting window sash 3 to rise and fall. When the acceleration sensor and speed sensor detect that the lifting window sash 3 exceeds the normal speed, it is determined that the lifting window sash 3 is in a stall state. At this time, the electromagnetic lock 6 and the mechanical lock 8 are activated. The electromagnetic lock 6 performs an emergency braking on the sheet chain 52, and the mechanical lock 8 directly performs an emergency braking on the lifting window sash 3 and the lifting window frame 1, thereby improving the safety of the lifting window.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
