Description

TECHNICAL FIELD

[0001] The present application relates to the field of door and window fittings, in particular to a self-locking door and window driving mechanism. BACKGROUND

[0002] Lift 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 the building. Existing lift doors and windows are generally divided into single-drive lift doors and windows and double-drive lift doors and windows. The single-drive lift doors and windows generally have lift wheel sets arranged on both sides of the door and window. The drive shaft connected to the drive motor drives the lift wheel sets on both sides to rotate forward or reverse, thereby enabling the door and window to lift. The double-drive lift doors and windows have a set of drive mechanisms arranged on both sides of the door and window. When the two sets of drive mechanisms operate synchronously, they can drive the door and window to lift. However, the above two types of lift doors and windows have their own disadvantages. For example, the single-drive lift doors and windows are prone to idling due to insufficient motor torque when in use, which prevents the door and window from lifting normally, and may even cause the door and window to fall directly. Some single-drive lift doors and windows need to be provided with a counterweight on the door and window, which greatly increases the weight of the product. The biggest problem faced by double-drive lift doors and windows is that the two sets of drive mechanisms may not operate synchronously. When the two sets of drive mechanisms are not synchronized, it may affect the normal lifting of the door and window, or even cause the door and window to deform and break.

[0039] Example 1

[0040] like Figures 1-6 As shown, a self-locking door and window drive mechanism includes a drive body 100 and two side guide frames 200 respectively disposed at the front and rear ends of the drive body 100 and connected to the drive body 100 by ropes.

[0041] The drive body 100 includes a housing 110, a drive part 120 disposed at the front end of the housing, a transmission part 130 connected to the front end of the drive part 120, a sliding part 140 cooperating with the transmission part 130, a track part 150 disposed in the housing 110 and cooperating with the sliding part 140, and a limiting structure 160 disposed in the housing 110 and used to limit the range of motion of the sliding part 140.

[0042] The side guide frame is existing technology. Its function is to change the direction of force on the rope and also to share the force with the driving body. Those skilled in the art can complete its installation and use without creative labor, so it will not be described in detail here.

[0043] The rope is made of steel, with its two ends fixed to the left and right sides of the door / window via two side guide frames. When the two ends are tightened, the door / window is pulled upward by the drive rope, and when the two ends are loosened, the door / window is pulled downward by its own weight. To improve the product's effectiveness, the rope can be set in two sets, symmetrically positioned at both ends of the two side guide frames, the sliding roller, and the fixed roller.

[0044] The shell part 110 is composed of a U-shaped shell body 111, an end cover 112 arranged at the rear end of the shell body 111, a fixed roller 113 arranged in the shell body 111 and adjacent to the end cover 112, and an upper cover 114 arranged on the upper side of the shell body 111; the end cover 112 is provided with a fixing hole for fixing the end cover 112 and a through hole for passing the rope.

[0045] The end cover is in the shape of "7", and the end cover is arranged in the shape of "7" to improve the positioning effect of the upper cover, reduce the positioning difficulty of the upper cover, facilitate the positioning and fixing of the upper cover, and greatly reduce the installation difficulty of the product.

[0046] The driving part 120 is composed of a U-shaped shaft coupling seat 122 fixed at the front end of the shell body 111, a shaft coupling 123 arranged in the U-shaped shaft coupling seat 122, and a driving motor 121 arranged at the front end of the U-shaped shaft coupling seat 122 and connected with the shaft coupling 123.

[0047] The driving motor can be a servo motor, which has better rotation accuracy and further improves the controllability of the opening and closing of the door and window.

[0048] The transmission part 130 is composed of a front bearing seat 131 arranged at the rear end of the U-shaped shaft coupling seat 122, a rear bearing seat 133 arranged at the rear end of the shell body 111 and adjacent to the fixed roller 113, and a lead screw 132 arranged at the two ends of the front bearing seat 131 and the rear bearing seat 133 and rotatable along the shaft.

[0049] The lead screw will rotate under the driving of the driving motor, and the sliding part will move forward or backward along the lead screw when the lead screw rotates.

[0050] The sliding part 140 is composed of a sliding seat 141 penetrated by the lead screw 132, a lead screw matching block 142 arranged at the front end of the sliding seat 141 and matched with the lead screw 132, and a self-locking structure arranged on the lower side of the sliding seat 141; the sliding seat 141 is provided with a sliding roller matched with the rope.

[0051] The lower side edge of the sliding seat can be arranged on the upper side of the rail strip, which is to reduce the downward force of the lead screw and better ensure that the lead screw will not be deformed due to the long-term pressure of the sliding part, but it should be noted that sufficient lubricant should be applied between the sliding seat and the guide rail strip to avoid large deformation of the sliding seat and the guide rail strip due to friction.

[0052] The self-locking structure is further composed of a connecting block 143 integrated with the sliding seat 141, a limiting block 144 arranged on the lower side of the connecting block 143, a permanent magnet block 145 embedded on the lower side of the limiting block 144, two rows of balls 146 arranged on the upper side of the limiting block 144 at the left and right edges, two rows of upper triangular blocks 147 arranged on the lower side of the limiting block 144 at the left and right edges, and at least two limiting guide rods 148 arranged on the lower side of the connecting block 143 and passing through the limiting hole 149, the limiting block 144 and the permanent magnet block 145 at the same time.

[0053] The track part 150 is composed of two track strips 151 parallel to each other and arranged on the bottom of the outer shell 111, two track grooves 152 symmetrically arranged on the opposite sides of the two track strips 151 respectively, lower triangular blocks 153 arranged on the lower side of the two track grooves 152 respectively, and an electromagnet 154 arranged on the bottom of the outer shell 111 and between the two track strips 151.

[0054] The distance between the upper side of the electromagnet 154 and the lower side of the connecting block 143 is greater than the length of the limiting guide rod 148; the width of the permanent magnet 145 is less than or equal to the width of the electromagnet 154; the two ends of the limiting block 144 respectively extend into the two track grooves 152; and the upper triangular blocks 147 and the lower triangular blocks 153 are arranged in a mirror image.

[0055] In order to ensure the use effect of the permanent magnet block and the electromagnet, the materials of the structures of the product need to be selected from materials that cannot be attracted by magnets, such as aluminum alloy, titanium alloy, stainless steel, etc.

[0056] When the product is not running, the electromagnet loses magnetic force after being powered off, the permanent magnet block is not forced, the limiting block naturally falls along the limiting guide rod under the action of gravity, the upper triangular block and the lower triangular block are staggered and overlapped together, thereby limiting the position of the limiting block, and finally the limitation is transmitted to the entire sliding part through the limiting guide rod, so that the sliding part also cannot move under the action of the rope.

[0057] When the electromagnet is powered on to generate magnetic force, the permanent magnet block is repelled by the electromagnet, and the permanent magnet block drives the limiting block to move upward along the limiting guide rod, and after the limiting block moves upward, the balls will be attached to the upper side of the guide rail groove, and the sliding friction between the limiting block and the upper side of the guide rail groove is changed to rolling friction through the arrangement of the balls, effectively reducing the friction and the waste of driving force of the driving motor; at the same time, since the limiting block moves upward, the upper triangular block and the lower triangular block are separated, so that the sliding part can easily move forward or backward along the track part under the action of the screw rod.

[0058] The limiting structure 160 is composed of a front limiting block 161 and a rear limiting block 162; two sliding grooves are arranged on the side walls of the outer shell 111 and are matched with the front limiting block 161 and the rear limiting block 162 respectively; the front limiting block 161 and the rear limiting block 162 are slidably and fixedly arranged in the two sliding grooves respectively

[0059] The limiting structure can adjust the specific positions of the front limiting block and the rear limiting block according to actual requirements, so as to limit the movement range of the sliding block, thereby meeting the requirements of doors and windows with different opening degrees.

[0060] A plurality of T-shaped holes are further arranged on the side walls of the outer shell, the arrangement of the T-shaped holes can facilitate the installation of the product, can facilitate the screwdriver to be inserted into the outer shell to tighten the fixing screws during the installation of the product, greatly reduces the installation difficulty of the product during actual use, and improves the installation efficiency of the product.

[0061] It should be noted that all the features disclosed in the specification, or the steps in all the disclosed methods or processes, can be combined in any manner, except for mutually exclusive features and / or steps.

[0062] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed range of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims.
