In order to solve the problem, the invention designs a linear motor structure for a telescopic sliding door, in particular to a telescopic rotor assembly, which comprises a fixed part and a movable part, wherein a permanent magnet is arranged on the fixed part, a part of the permanent magnet is exposed outside, and the exposed part is positioned under a stator assembly. The lower part of the permanent magnet is also provided with a slot hole, the telescopic rod of the movable part is inserted into the slot hole and can slide left and right in the slot hole, the movable part is also provided with a motion output part, and the motion output part is connected with the door body and can output the motion of the rotor assembly to the door body. Since the fixed portion slides laterally by the magnetic force and the movable portion is inserted into the slot of the fixed portion by the telescopic rod, it is also necessary to connect and fix the movable portion and the fixed portion by using a fastener in order to transfer the sliding motion of the fixed portion to the movable portion.
Therefore, aiming at the situation that the width of the door frame is different, the extension and shortening of the rotor assembly can be realized only by adjusting the length of the telescopic rod inserted into the slot hole, namely, when the width of the door frame is wider, the telescopic rod is pulled out of the slot hole a little more, and when the width of the door frame is narrower, the telescopic rod is pulled out of the slot hole a little less, namely, the length of the telescopic rod pulled out of the slot hole can be flexibly adjusted according to different requirements, so that the rotor assembly can be suitable for various situations with different width of the door frame and has good universality. Once the length of the telescopic rod is adjusted according to a specific occasion, the movable part and the fixed part can be connected and fixed by adopting a fastener, so that the sliding of the movable part and the fixed part is synchronous, and the sliding can be further transmitted to the door body through the motion output part on the movable part to drive the door body to be opened and closed.
Further, in one embodiment, the fixing portion includes an upper portion and a lower portion, and the length of the upper portion of the fixing portion is greater than the length of the lower portion of the fixing portion, and a slot hole for inserting the telescopic rod is formed between the upper portion and the lower portion. The purpose of setting like this is in order to make the motion output part of movable part can slide to the below of fixed part upper portion to with the tip contact of fixed part lower portion, just so can further shorten the length of whole mover assembly, thereby make it can be applicable to narrower door frame, furthest strengthens the adaptability of mover assembly.
Further, one end of the telescopic rod is inserted into the slot, the other end of the telescopic rod is connected with the guide pulley, the guide pulley can slide in the slot, pulleys are arranged on two sides of the guide pulley, and the motion output part is arranged in the middle of the guide pulley.
Further, one end of the telescopic rod is inserted into the slotted hole, and the length of the telescopic rod pulled out of the slotted hole is adjusted according to actual needs, so that the telescopic function of the rotor assembly is realized. The other end of the telescopic rod is connected with a guide pulley which can slide in the slotted hole, when the door frame is narrower, the guide pulley slides in the slotted hole along with the telescopic rod and can slide to the end part of the lower part of the fixed part and is positioned below the upper part of the fixed part, so that the rotor assembly can adapt to the narrower door frame. In addition, the motion output part is arranged in the middle of the guide pulley, and when the guide pulley is used, the motion output part is connected with the door body, and when the guide pulley slides in a track along with the telescopic rod, the door body connected with the guide pulley is driven to slide synchronously.

As shown in fig. 1 and 10, the linear motor structure for a retractable sliding door comprises a mover assembly 1, wherein the mover assembly 1 comprises a fixed part 11 and a movable part 13, the fixed part 11 is provided with a permanent magnet 111, a slot 112 is arranged below the permanent magnet 111, the movable part 13 is provided with a telescopic rod 14 which can be slidably inserted from one end of the slot 112, and a motion output part 15 which can output the motion of the mover assembly 1, and the movable part 13 and the fixed part 11 are fixed by a fastener 19.
In the prior art, the mover assembly 1 is generally not adjustable, once it is determined, it can only be used on a door frame with a specific width, but for other door frames with different widths, the mover assembly 1 corresponding to the door frame can only be produced again, that is, the situation where the mover assembly 1 in the prior art is applicable is fixed and does not have the capability of adapting to various door frame widths, so that manufacturers must design the mover assembly 1 with one specification for each door frame width during production, thereby causing the defects of various varieties, high cost and the like. In order to solve the problem, the invention designs a linear motor structure for a telescopic sliding door, in particular to a telescopic rotor assembly 1, wherein the rotor assembly 1 comprises a fixed part 11 and a movable part 13, a permanent magnet 111 is arranged on the fixed part 11, a part of the permanent magnet is exposed outside, and the exposed part is positioned right below a stator assembly 2, when the stator assembly 2 is electrified, the fixed part 11 of the rotor assembly 1 positioned below the stator assembly 2 moves left and right along a track 3 under the pushing action of magnetic field force due to the electromagnetic induction principle. The permanent magnet 111 is also provided with a slot 112 below, the telescopic rod 14 of the movable part 13 is inserted into the slot 112 and can slide left and right in the slot 112, the movable part 13 is also provided with a motion output part 15, and the motion output part 15 is connected with the door body 4 and can output the motion of the rotor assembly 1 to the door body 4. Since the fixed portion 11 slides laterally by the magnetic force and the movable portion 13 is inserted into the slot 112 of the fixed portion 11 through the telescopic rod 14, the movable portion 13 and the fixed portion 11 must be connected and fixed by the fastener 19 in order to transmit the sliding motion of the fixed portion 11 to the movable portion 13.
In this way, for the occasions with different door frame widths, only the length of the telescopic rod 14 inserted into the slot 112 needs to be adjusted, so that the extension and shortening of the rotor assembly 1 can be realized, namely, when the door frame width is wider, the telescopic rod 14 is pulled out of the slot 112a little more, and when the door frame width is narrower, the telescopic rod 14 is pulled out of the slot 112a little less, that is, the length of the telescopic rod 14 pulled out of the slot 112 can be flexibly adjusted according to different requirements, so that the rotor assembly 1 can be suitable for various occasions with different door frame widths, and has good universality. Once the length of the telescopic rod 14 is adjusted according to a specific occasion, the movable part 13 and the fixed part 11 can be connected and fixed by adopting the fastener 19, so that the sliding of the movable part 13 and the fixed part 11 is synchronous, and the sliding can be further transmitted to the door body 4 through the motion output part 15 on the movable part 13 to drive the door body 4 to be opened and closed.
Further, in one embodiment, as shown in fig. 2-9, the fixing portion 11 is divided into an upper portion 114 and a lower portion 115, wherein the length of the upper portion 114 of the fixing portion is longer than that of the lower portion 115 of the fixing portion, and a slot 112 is formed between the upper portion 114 and the lower portion 115 for inserting the telescopic rod 14. The purpose of this arrangement is to enable the movement output portion 15 of the movable portion 13 to slide below the fixed portion upper portion 114 and contact the end of the fixed portion lower portion 115, which can further shorten the length of the entire mover assembly 1, thereby enabling it to be applied to a narrower door frame and maximally enhancing the adaptability of the mover assembly 1.
Further, one end of the telescopic rod 14 is inserted into the slot 112, the other end is connected with a guide pulley, the guide pulley 16 can slide in the slot 112, the pulleys 12 are arranged at two sides of the telescopic rod, and the motion output part 15 is arranged in the middle of the guide pulley 16.
Further, one end of the telescopic rod 14 is inserted into the slot 112, and the length of the telescopic rod pulled out of the slot 112 is adjusted according to actual needs, so that the telescopic function of the rotor assembly 1 is realized. The other end of the telescopic rod 14 is connected to a guide pulley 16, which guide pulley 16 is slidable in a slot 112. When the door frame is narrower, the guide pulley 16 follows the telescopic rod 14 to slide in the slot 112 and can slide to the end of the fixed lower portion 115 and under the fixed upper portion 114, which enables the mover assembly 1 to accommodate the narrower door frame. In addition, the motion output part 15 is arranged in the middle of the guide pulley 16, when the motion output part 15 is connected with the door body 4 in use, when the guide pulley 16 slides in the track 3 along with the telescopic rod 14, the door body 4 connected with the guide pulley is driven to slide synchronously.
