[0015] See also Figures 1 to 4 , provided in one embodiment of the utility model, is a frame sliding door structure, comprising a housing 101, and further comprising:

[0016] Door panel assembly 2, used to control the opening and closing of the door panel;

[0017] The door panel assembly 2 includes a door panel A201, a door panel B202 and a slider 203. The door panel A201 is rotatably connected to the shell 101 via a short axis thereon. The door panel B202 is hinged to the door panel A201. The other end of the door panel B202 is rotatably connected to the slider 203. The slider 203 is slidably connected to the shell 101.

[0018] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific door panels A201 and B202 described in the above embodiments. For example, sealing strips are provided at the frames of the door panels A201 and B202. The purpose of this setting is to increase the tightness of the connection in this way, thereby improving the airtightness of the device.

[0019] Specifically, the slider 203 is threadedly connected to the screw rod 204 , the screw rod 204 is rotatably connected to the housing 101 , and a main shaft 207 is rotatably connected to the housing 101 .

[0020] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific shell 101 described in the above embodiments. For example, multiple bolts are provided on both sides of the shell 101. The purpose of this arrangement is to facilitate the installation of the shell 101 at a predetermined position by bolts and to facilitate the transportation of the device.

[0021] Specifically, the upper and lower sides of the main shaft 207 are fixedly connected with worms 208 respectively, and the two worms 208 are meshedly connected with worm wheels 206 respectively. Any one of the worm wheels 206 is fixedly connected to the screw 204, and the axis of the other worm wheel 206 is fixedly connected with a left-handed screw 209.

[0022] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific main shaft 207 described in the above embodiments. For example, a bearing ring is provided at the connection between the main shaft 207 and the housing 101. The purpose of this arrangement is to prevent the main shaft 207 from breaking in this way.

[0026] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific slide 302 described in the above embodiments. For example, a damping rubber strip is provided at the connection between the slide 302 and the shell 101. The purpose of this setting is to increase the friction at the connection in this way and prevent abnormal noise when sliding.

[0027] Specifically, the two slide cylinders 302 are respectively hinged with support rods A303, and the other ends of the two support rods A303 are hinged to support rods B304. A damping rubber ring is provided at the hinged joint between the support rods A303 and B304.

[0028] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific support rod A303 described in the above embodiments. For example, the support rod A303 should be made of an integrated material. The purpose of this setting is to prevent it from being broken by stress in this way.

[0029] Specifically, a gear 305 is fixedly connected to the main shaft 207 , and the gear 305 is meshedly connected with a gear fixedly assembled on the output shaft of the motor 306 , and the motor 306 is fixedly connected to the housing 101 .

[0030] For the above example, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific motor 306 described in the above embodiment. For example, the motor 306 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate controlling the opening speed of the door panel by adjusting its output frequency.

[0031] In the embodiment of the utility model, the relevant technicians start the motor 306, so that the motor 306 drives the gear 305 meshing with its output gear to start rotating, so that the main shaft 207 fixedly connected at the axis of the gear 305 rotates synchronously, so that the worm 208 fixedly connected on the main shaft 207 rotates synchronously, so that the worm 208 drives the worm wheel 206 meshing with it to start rotating, so that the worm wheel 206 drives the screw rod 204 fixedly connected at its axis to start rotating, so that the slider 203 threadedly connected on the screw rod 204 starts to move linearly along the connection between it and the shell 101, so that the slider 203 drives the door panel B202 rotatably connected to it to start synchronous movement, so that the door panel A201 moves with its rotational connection with the shell The connection between the body 101 begins to fold, and at the same time, the connection between the door panel A201 and the door panel B202 begins to bulge, and at this time, the left-handed screw 209 fixedly connected at the axis of the worm gear 206 begins to rotate, so that the left-handed screw 209 drives the right-handed screw 301 fixedly connected thereto to rotate synchronously, so that the left-handed screw 209 and the slide 302 threadedly connected on the right-handed screw 301 begin to move linearly along the connection between them and the shell 101, so that the right-handed screw 301 begins to push the support rod A303 hinged thereto to move synchronously, so that the support rod A303 begins to push the support rod B304 hinged thereto to start linear movement, so as to push away the debris near the door panel through the support rod B304 to prevent the impurities from blocking the door panel from opening and causing damage to the door panel.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0034] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0035] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0036] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
