Description

Technical Field

[0001] The present application relates to the field of door and window accessories, and more specifically to a lifting door and window driving mechanism. Background Art

[0002] Lifting doors and windows are favored by many consumers because they do not occupy indoor space, are flexible to open, can effectively increase indoor lighting, and improve the overall appearance of buildings. Existing lifting doors and windows are generally divided into single-drive lifting doors and windows and double-drive lifting doors and windows. Single-drive lifting doors and windows generally first set lifting wheel groups on both sides of the door and window, and drive the lifting wheel groups on both sides to rotate forward or reversely through the driving shaft connected to the driving motor, thereby achieving the lifting process of the door and window; double-drive lifting doors and windows are respectively set on both sides of the door and window. When the two sets of driving structures are running synchronously, they can drive the door and window to achieve lifting. However, the above two types of lifting doors and windows have their own disadvantages: for example, when single-drive lifting doors and windows are in use, it is easy to cause idling due to insufficient motor torque, making it impossible for the doors and windows to be lifted normally, and may even cause the doors and windows to fall directly. Some single-drive lifting doors and windows need to be equipped with counterweights with the same weight as the doors and windows, which greatly increases the weight of the product; the biggest problem faced by dual-drive lifting doors and windows is that the two sets of drive mechanisms may be out of sync during operation. When the two sets of drive mechanisms are out of sync, it may affect the normal lifting of the doors and windows at the least, and may cause the doors and windows to deform and break at the worst.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Example 1

[0030] like Figure 1-3 As shown, a lifting door and window driving mechanism includes two side guide frames 200 relatively arranged at the two ends of the door and window, a driving body 100 arranged between the two side guide frames 200, a driving rope whose two ends are connected to the two ends of the door and window after passing through the side guide frames 200, a driving rope whose middle is arranged on the driving body 100, and a controller connected to the driving body 100; a sliding pad block 105 is arranged in the driving body 100.

[0031] The driving rope is a steel rope, and its two ends are fixed to the left and right sides of the door and window through two side guide frames. When the two ends are tightened, the door and window will be pulled up by the driving rope, and when the two ends are loosened, the door and window will drive the driving rope downward under the action of its own gravity. In order to improve the effect of the product, the number of driving ropes can be set to two groups, which are symmetrically set at the two side guide frames, the sliding roller and the two ends of the fixed roller.

[0032] The driving body 100 is composed of a shell structure, a driving structure arranged in the shell structure, and a functional component arranged in the shell structure and matched with the driving structure.

[0033] The outer shell structure consists of a U-shaped trough shell 101 that passes through from front to back, an end cover 103 whose side is in the shape of a "7" and is arranged on the rear side of the U-shaped trough shell 101 and whose upper side rests on the rear end of the upper side of the U-shaped trough shell 101, and an upper cover 102 that is arranged on the upper side of the U-shaped trough shell 101 and whose rear end abuts against the end cover 103.

[0034] The purpose of setting the end cover in a "7" shape is to improve the positioning effect of the upper cover, reduce the difficulty of positioning the upper cover, make it easier to position and fix the upper cover, and greatly reduce the difficulty of product installation.

[0035] The driving structure comprises a guide rail 104 fixed to the bottom of the U-shaped groove shell 101, a front bearing block 108 arranged at the bottom of the U-shaped groove shell 101 and located in front of the guide rail 104, a rear bearing seat 111 arranged at the bottom of the U-shaped groove shell 101 and located behind the guide rail 104, a rear bearing arranged on the rear bearing seat 111, a screw rod 109 arranged above the guide rail 104, the rear end of which is fixed to the rear bearing and the front end of which passes through the front bearing block 108, and a screw rod 109 arranged at the top of the U-shaped groove shell 101. 01 groove bottom and located in front of the front bearing block 108, a coupling 107 arranged in the U-shaped coupling seat 112 and connected to the screw rod 109, and a servo motor 106 arranged in the front side of the U-shaped coupling seat 112 and connected to the coupling 107; the U-shaped coupling seat 112 is also symmetrically provided with two coupling seat reinforcement plates 113, and the coupling seat reinforcement plates 113 are inserted into the front side wall and the rear side wall of the U-shaped coupling seat 112 at the same time.

[0036] The lead screw will rotate under the drive of the servo motor, and when the lead screw rotates, it will push the matching block forward or backward along the lead screw.

[0037] The functional component consists of a screw rod matching block 114 which is sleeved on the screw rod 109 and matched with the screw rod 109, a connecting block 115 which is sleeved on the screw rod 109 and fixed on the screw rod matching block 114, a sliding seat 116 which is sleeved on the screw rod 109 and fixed on the connecting block 115, a sliding roller 117 which is arranged on the sliding seat 116 and is perpendicular to the setting direction of the guide rail 104, and a fixed roller 118 which is arranged at the rear section of the U-shaped groove shell 101 and is at the same height as the sliding roller 117 and is arranged parallel to the sliding roller 117; the sliding pad block 105 is fixed below the sliding seat 116 and is slidably arranged on the guide rail 104.

[0038] The matching block will move forward or backward along the lead screw. When the matching block moves along the lead screw, it will drive the connecting block and the sliding seat to move. Due to the limitation of the guide rail, the sliding seat will move forward or backward on the guide rail along the direction of the lead screw.

[0039] like Figure 4 , 5 As shown, the sliding pad 105 is in an inverted U shape, and the bottom of the slide groove 124 of the sliding pad 105 is fitted on the guide rail 104. A plurality of oil injection chambers 126 parallel to the guide rail 104 are arranged in the sliding pad 105, and each of the oil injection chambers 126 is provided with an extrusion hole 125 connected to the slide groove 124.

[0040] The sliding pad is made of rubber or plastic. When in use, lubricating oil needs to be applied to the guide rail to improve the sliding smoothness of the sliding pad, and at the same time, it can effectively reduce the wear rate of the sliding pad. However, as the use time increases, the lubricating effect of the lubricating oil will gradually decrease under the long-term back and forth sliding of the sliding pad, which will lead to a gradual increase in the wear rate of the sliding pad. Frequent disassembly and assembly to replenish the lubricating oil is obviously unrealistic. Therefore, this embodiment sets an oil filling chamber in the sliding pad. In addition to applying lubricating oil on the guide rail during use, lubricating oil can also be added to the oil filling chamber. When the friction between the sliding pad and the guide rail increases, the sliding pad will be deformed to a certain extent due to the friction, and the lubricating oil in the oil filling chamber will be squeezed out from the extrusion hole, thereby achieving the effect of replenishing the guide rail lubricating oil, greatly extending the service life of the product and reducing the maintenance frequency of the product.

[0041] A front limit groove 119 is horizontally arranged on the front section of the side wall of the U-shaped trough shell 101, and a rear limit groove 120 is horizontally arranged on the rear section of the side wall of the U-shaped trough shell 101; a front limit block 121 fixed on the front limit groove 119 is arranged on the inner wall of the U-shaped trough shell 101, and a rear limit block 122 fixed on the rear limit groove 120 is arranged on the inner wall of the U-shaped trough shell 101.

[0042] The front limit block and the rear limit block can effectively limit the travel range of the sliding seat. Since the running length of the sliding seat required by different products is different, the position of the front limit block and the rear limit block can be adjusted according to actual usage requirements, further improving the use effect of the product.

[0043] A plurality of T-shaped holes 123 are also provided on the side walls of the U-shaped trough shell 101 .

[0044] The T-shaped hole can facilitate the installation of the product. It can be convenient for the screwdriver to be inserted into the U-shaped groove shell to tighten the fixing screws during the installation of the product, which greatly reduces the installation difficulty of the product in actual use and improves the installation efficiency of the product.

[0045] The controller is electrically connected to the servo motor 106 , and the servo motor 106 is also provided with a brake electrically connected to the controller; the front limit block 121 and the rear limit block 122 are respectively provided with a touch button electrically connected to the controller.

[0046] The purpose of setting the brake is to ensure that the servo motor will not rotate in the reverse direction under the action of external force when it stops, thereby ensuring that the doors and windows will not drive the screw rod to rotate in the reverse direction under the action of gravity when in use, ensuring the stability of the doors and windows and improving the safety of the use of the doors and windows.

[0047] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0048] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims.
