However, the existing technical solutions of ground rail-free sliding door still have two major defects, which seriously limit its further promotion and application: The buffer structure has insufficient performance: in order to avoid collision with the frame when the door leaf slides, the existing products mostly use traditional buffer structures such as springs and hydraulic rods, but such structures have obvious limitations, one is that the buffer force is fixed and cannot be adjusted adaptively according to the sliding acceleration of the door leaf, and usually only the door leaf can be buffered at both ends of the sliding direction, and the buffering effect is not good; two is that the sealing and precision of the door leaf closing may be affected due to improper adjustment, aging and failure; The disassembly and maintenance is difficult: the pulley assembly of the existing ground rail-free sliding door is mostly pre-installed in the sliding cavity of the top rail, and the ends of the rail are usually closed by the door frame or wall, once the pulley is worn, damaged, the rail is deformed or the buffer structure is aged and damaged, the pulley assembly and the buffer structure need to be removed for maintenance, which not only is tedious and time-consuming, but also causes additional maintenance cost, which has a negative impact on the user experience.

DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings, in which several embodiments of the present application are given, but the present application can be realized in different forms and is not limited to the embodiments described herein, on the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixedly attached" to another element, it can be directly on the other element or there can be intervening elements, and when an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be intervening elements, the terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Please refer to the accompanying drawings Figures 1-11 A push-pull upper rail connecting device, comprising: The upper slide rail 1 is internally provided with a sliding cavity 2 with an open bottom, and both sides of the sliding cavity 2 are provided with wheel rails 3; The buffer track 4 is arranged in the sliding cavity 2 and parallel to the upper slide rail 1, and a plurality of ring magnets 5 are arranged along the length direction on the buffer track 4; The buffer sliding block 6 is slidably sleeved on the buffer track 4, and the buffer sliding block 6 is provided with an insulating coil 7 arranged along the length direction of the buffer track 4, and the bottom of the buffer sliding block 6 is provided with a plug-in part 8; The hoisting base 9 is arranged at the top of the door leaf, the hoisting base 9 is provided with storage holes 10 penetrating through both sides thereof, and the upper end of the hoisting base 9 provided with the storage holes 10 can be inserted into the sliding cavity 2; The door panel hanging assembly 12 is mounted on the hanging base 9. The door panel hanging assembly 12 includes a horizontal shaft 1202 rotatably mounted in the storage hole 10 via a vertical shaft 1201, and two rollers 1203 rotatably mounted at both ends of the horizontal shaft 1202. The vertical shaft 1201 drives the horizontal shaft 1202 to rotate, causing the rollers 1203 to move from the storage hole 10 to above the wheel rail 3. The lower linkage structure is located on the top of the hoisting base 9. The lower linkage structure is connected to the plug-in part 8 to realize the linkage between the hoisting base 9 and the buffer slider 6.

[0022] The state switching component 28 is mounted on the lifting base 9 and connected to the vertical shaft 1201. The state switching component 28 is used to drive the vertical shaft 1201 to rotate, thereby switching the position of the roller 1203.

[0023] During door installation, at least two ends of the top of the door leaf are fitted with mounting bases 9 secured by fastening screws. After the buffer rail 4 with the buffer slider 6 is installed into the sliding cavity 2, the two rollers 1203 of the door leaf mounting assembly 12 are housed in the storage holes 10 by the lower linkage structure. Subsequently, the door leaf with the mounting bases 9 on top is lifted, so that the upper part of the mounting base 9 with the storage holes 10 passes through the opening at the bottom of the sliding cavity 2 and enters the sliding cavity 2. The lower linkage structure at the top of the mounting base 9 aligns with and locks with the connector 8 at the bottom of the buffer slider 6, thereby connecting the buffer slider 6 to the door leaf. At this time, since the door leaf is lifted, the rollers 1203 are located above the plane of the two side rails 3. The state switching assembly 28 drives the vertical shaft 1201 to rotate the horizontal shaft 1202, so that the two rollers 1203, which were originally located in the storage holes 10, move above the two side rails 3 as the horizontal shaft 1202 rotates. After all the rollers 1203 at the top of the door leaf have moved to the wheel rail 3 in the above manner, the door leaf is released, so that the door leaf is suspended on the upper slide rail 1 by means of the multiple sets of rollers 1203 at the top.

[0024] When disassembling the door leaf, lift the door leaf so that the state switching component 28 drives the rollers 1203 at both ends of the horizontal shaft 1202 to move into the storage hole 10. When all the rollers 1203 at the top of the door leaf have moved into the corresponding storage hole 10, the lower linkage structure contacts and locks with the buffer slider 6. Then, operate the door leaf to disengage the lower linkage structure from the buffer slider 6 until the lifting base 9 and the lower linkage structure are removed from the sliding cavity 2, thus completing the disassembly of the door leaf. The rollers 1203 are also removed along with the door leaf to facilitate the replacement of worn or damaged rollers 1203 and the maintenance of the door leaf lifting component 12.

[0025] When the door is in use, the sliding door causes the insulated coil 7 on the buffer slider 6 to cut the magnetic field lines around the annular magnet 5 on the buffer track 4, thereby inducing a current in the insulated coil 7. This induced current, as it passes through the insulated coil 7, creates a magnetic field around it that opposes the relative motion of the other annular magnets 5, thus buffering the door. Especially when the door slides rapidly, the magnetic flux increases rapidly in a short time, causing the induced current and magnetic field in the insulated coil 7 to increase rapidly as well, thus achieving adjustable buffering force based on the door's acceleration. Compared to buffering methods using springs or hydraulic rods, this method has the advantages of adaptively adjusting the buffering force according to the door's acceleration, simple structure, easy installation, and the ability to buffer the door at any position.

[0026] The buffer track 4 includes a cylindrical rod 401 and a partition sleeve 402. Multiple partition sleeves 402 are equally spaced on the cylindrical rod 401. The annular magnet 5 is located in the annular groove formed between adjacent partition sleeves 402. The outer diameter of the annular magnet 5 is the same as the outer diameter between the partition sleeves 402. The cylindrical rod 401 is provided with positioning holes 13 at multiple partition sleeves 402. The partition sleeves 402 are provided with through holes 14. The cylindrical rod 401 is connected to the crossbeam 15 by screws passing through the through holes 14 and positioning holes 13, so as to facilitate the disassembly and assembly of the buffer track 4 and the ring magnet 5, and to facilitate the replacement of the ring magnet 5.

[0027] The partition sleeve 402 serves two purposes. First, it facilitates the connection between the cylindrical rod 401 and the crossbeam 15. Multiple partition sleeves 402 are fixed to the crossbeam 15 with screws, achieving a multi-point stable connection between the buffer track 4 and the crossbeam 15. Second, the annular magnet 5 is axially positioned by two adjacent partition sleeves 402, preventing axial movement of the annular magnet 5 on the cylindrical rod 401 and ensuring that the door's buffering function can be properly implemented.

[0028] Correspondingly, the buffer slider 6 has a central hole 16 at its axial center position, and the side of the buffer slider 6 has a fan-shaped notch 17 that connects to the central hole 16. The fan-shaped notch 17 passes through both ends of the buffer slider 6, and the central angle corresponding to the fan-shaped notch 17 is less than 180°, so as to ensure that the buffer slider 6 can be slidably sleeved on the buffer track 4 through the central hole 16. The fan-shaped notch 17 is located above the buffer track 4. A crossbeam 15 is provided on the wall of the sliding cavity 2 along the length of the buffer track 4. The bottom of the crossbeam 15 passes through the fan-shaped notch 17 and is connected to the buffer track 4.

[0029] The buffer track 4 is hoisted via the crossbeam 15. Compared to supporting the buffer track 4 at both ends, this method prevents the buffer track 4 from bending due to gravity. Especially when the buffer track 4 is long, it effectively maintains the straightness of the buffer track 4, preventing collisions between the buffer slider 6 and the buffer track 4 or the ring magnet 5 when the door leaf moves along the buffer track 4. The fan-shaped notch 17 on the buffer slider 6 avoids the crossbeam 15, allowing the buffer slider 6 to slide on the buffer track 4, which is hoisted by the crossbeam 15.

[0030] Furthermore, the design of the fan-shaped notch 17 allows the buffer slider 6 to rotate around the buffer track 4 within a certain range. When installing the door leaf, the door leaf can be tilted at a certain angle to reduce the total vertical height of the door leaf and the hanging base 9, so that the hanging base 9 can be inserted into the sliding cavity 2. By allowing the buffer slider 6 to rotate around the buffer track 4 by a corresponding angle, the lower linkage structure at the top of the hanging base 9 can be aligned with the plug-in 8 at the bottom of the buffer component, thereby realizing the docking of the lower linkage structure and the plug-in 8.

[0031] In addition, the top of the wheel rail 3 is provided with an arc-shaped anti-deviation groove 30. The difference between the outer diameter of the roller 1203 and the diameter of the horizontal shaft 1202 is greater than the depth of the anti-deviation groove 30. The anti-deviation groove 30 is used to guide and limit the roller 1203, that is, to prevent the roller 1203 from rotating horizontally and leaving the wheel rail 3, while guiding the roller 1203 to roll in a straight line along the wheel rail 3. The contour of the anti-deviation groove 30 is adapted to the shape of the roller 1203. Preferably, the wheel surface of the roller 1203 is arc-shaped, so that the roller 1203 can roll normally when the door leaf is subjected to vertical force.

[0032] It should be noted that the buffer slider 6 can be adjusted to a tilted state using tools such as tape or levers.

[0033] It should be noted that the above-described method of inserting the mounting base 9 into the sliding cavity 2 by operating the door leaf and connecting the connector 8 with the lower linkage structure is based on the case where the mounting base 9 and the door leaf are pre-installed. However, it is also possible to first insert the mounting base 9 into the sliding cavity 2, lock the connector 8 with the lower linkage structure, and adjust the roller 1203 before installing the mounting base 9 to the top of the door leaf using fasteners.

[0034] It should be understood that the above-described door installation method is based on conventional door assembly methods. On the one hand, this facilitates the understanding of the technical solution, and on the other hand, it avoids obscuring the key points of the technical solution of this invention. That is, the installation method and optimization scheme of the hanging base 9 and the door are not the core of the technical solution of this invention, and will not be elaborated here.

[0035] To avoid the insulating coil 7 on the buffer slider 6 from interfering with the crossbeam 15, the insulating coil 7 can be set in an arc shape or a circle. In addition, the buffer slider 6 is provided with a plurality of insertion holes 18 arranged around the buffer track 4. The insulating coil 7 is placed in the insertion holes 18 to facilitate the installation of the insulating coil 7 and to prevent the insulating coil 7 from bending under the action of gravity.

[0036] Furthermore, the insulated coil 7 is a spiral elastic structure made of beryllium copper enameled wire. Both ends of the insulated coil 7 are electrically connected to conductive slip rings 19, and the conductive slip rings 19 are slidably disposed in the insertion hole 18. When the door accelerates, the conductive slip rings 19 compress the insulated coil 7 by inertia, so as to enhance the strength of the induced magnetic field generated by the insulated coil 7.

[0037] Beryllium copper possesses high strength, elasticity, hardness, and fatigue strength, along with excellent physical, chemical, and mechanical properties such as low elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetism, and no sparking upon impact. The helical insulated coil 7, wound with beryllium copper enameled wire, exhibits excellent elasticity. When the door slides with acceleration, for example, to the left, the conductive slip ring 19 on the left will move to the right relative to the insulated coil 7 under inertia, thus compressing the insulated coil 7 and reducing its length. The magnetic field strength of the insulated coil 7 is calculated using the formula H = N × I / L (H: magnetic field strength; N: number of turns of the insulated coil 7; I: current flowing through the insulated coil 7; L: effective length of the insulated coil 7). Therefore, when the insulated coil 7 is compressed by the conductive slip ring 19, the magnetic field strength generated by the insulated coil 7 increases, thereby enhancing the buffering effect on the door.

[0038] In addition, the insulating coil 7 is made of multiple strands of beryllium copper enameled wire arranged in a cylindrical or sheet shape, and then wound in a spiral shape after being shaped by gluing and binding. That is, the strength of the induced magnetic field generated by the insulating coil 7 is enhanced by increasing the number of turns of the insulating coil 7. By adjusting the number of turns of the insulating coil 7 and selecting ring magnets 5 with different magnetic forces, the buffering needs of door leaves of different sizes and weights can be met.

[0039] Furthermore, the conductive slip ring 19 is preferably made of an iron-copper alloy, or a metal sheet made of iron, cobalt, nickel, or their alloys is provided on the side of the two conductive slip rings 19 that are close to each other. By using a hysteresis material, the conductive slip ring 19 generates hysteresis. When the insulating coil 7 is compressed, since the conductive slip rings 19 at both ends are magnetized by the energized insulating coil 7, and the magnetic poles of the conductive slip rings 19 at the ends that are close to each other are in opposite directions, the two conductive slip rings 19 at both ends attract each other through magnetic force, thereby slowing down the reset of the conductive slip rings 19 under the elastic force of the insulating coil 7, that is, slowing down the restoration of the insulating coil 7 to its initial length.

[0040] When the door's acceleration decreases but its speed remains high, the insulating coil 7 will not quickly return to its initial length due to the decrease in door acceleration (although the magnetic field strength of the insulating coil 7 weakens, the conductive slip rings 19 at both ends will still retain relatively strong magnetism for a period of time due to hysteresis), thus effectively buffering the door.

[0041] Furthermore, when the door slides back and forth quickly, for example, when the door slides quickly to the left and then quickly to the right, due to the mutual attraction of the conductive slip rings 19 at both ends, while the left conductive slip ring 19 is slowed down by the inertia and the elastic force of the insulating coil 7 to return to its original position, the right conductive slip ring 19 will further compress the insulating coil 7 under the action of inertia and magnetic force, thereby further enhancing the buffering effect on the door. A further optimization of the above embodiment is that both ends of the buffer slider 6 are provided with arc-shaped end caps 20, and the inner side of the arc-shaped end caps 20 is provided with multiple guide copper pillars 21, which are inserted into the corresponding insertion holes 18. The conductive slip ring 19 is sleeved on the guide copper post 21 and is electrically connected to the guide copper post 21. Under the elastic force of the insulating coil 7, the two conductive slip rings 19 respectively abut against the inner side of the two arc-shaped end caps 20. The insulated coil 7 is sleeved on two coaxial and spaced guide copper pillars 21, and the two guide copper pillars 21 are connected by an insulating pad 22. The arc-shaped end cap 20 is provided with an arc-shaped copper sheet 23 electrically connected to a plurality of guide copper pillars 21, and the arc-shaped end cap 20 is provided with a sliding contact 24 electrically connected to the arc-shaped copper sheet 23; The sliding cavity 2 is provided with a pair of conductive slide rails 25, and the sliding contacts 24 on the two arc-shaped end caps 20 are respectively electrically connected to the two conductive slide rails 25.

[0042] The insertion holes 18 are sealed by the arc-shaped end caps 20 at both ends, preventing dust and moisture from entering and extending the service life of the insulated coil 7 and the conductive slip ring 19. Furthermore, when the door is stationary, the conductive slip ring 19, under the elastic force of the insulated coil 7, abuts against the arc-shaped end caps 20, preventing a large gap between the conductive slip ring 19 and the arc-shaped end caps 20 from causing a lag in the compression of the insulated coil 7 when the door accelerates. The conductive slip ring 19 is slidably fitted onto the guide copper post 21. The insulated coil 7 is electrically connected to the arc-shaped copper sheet 23 on the arc-shaped end cap 20 through the conductive slip ring 19 and the guide copper post 21, thereby achieving electrical connection between the arc-shaped end and one end of multiple insulated coils 7.

[0043] The sliding contact 24 on the arc-shaped end cap 20 is electrically connected to the corresponding conductive slide rail 25, thereby transmitting the induced current generated by the multiple insulated coils 7 to the electronic devices connected to the two conductive slide rails 25, thus powering the sensors, controllers, and batteries. For example, powering or auxiliary powering small smart home devices such as irradiance sensors and door / window sensors via batteries or directly is not only energy-saving and environmentally friendly, but also in line with the trend of smart home development. It can meet the direct power supply needs of small electronic devices such as door / window sensors, temperature and humidity sensors, and irradiance sensors, reducing the layout of power supply lines. Furthermore, it is achieved through the integration of the door's buffer structure and installation structure, eliminating the need for a separate mechanical energy conversion power generation device.

[0044] The sliding contact 24 includes a sliding electrode 2401 and a copper spring 2402. The sliding electrode 2401 is electrically connected to the conductive slide rail 25. The sliding electrode 2401 is electrically connected to the arc-shaped copper sheet 23 through the elastically bent copper spring 2402. The function of the copper spring 2402 is, on the one hand, to electrically connect the sliding electrode 2401 and the arc-shaped copper sheet 23. On the other hand, when the door swings in a direction perpendicular to the door during the sliding process, the buffer slider 6 will rotate on the buffer track 4, causing the distance between the top two sides of the buffer slider 6 and the two conductive slide rails 25 to change. Therefore, the flexible copper spring 2402 is used to adapt to the change in distance between the buffer slider 6 and the conductive slide rail 25.

[0045] Both sides of the insertion hole 11 are provided with arched rubber blocks 26. The arc surfaces of the two arched rubber blocks 26 form a gap for the insertion of the connector 8. The two arched rubber blocks 26 can restrict the lateral relative movement between the lifting base 9 and the connector 8, while also accommodating the change in the relative angle between the lifting base 9 and the connector 8 when the door is subjected to a vertical force and swings. Both ends of the insertion hole 11 are provided with elastic rubber buffer blocks 27 to buffer the impact between the lifting base 9 and the connector 8 when the door slides and stops.

[0046] The state switching component 28 includes an operating lever 2801 and a bushing 2802, with one end of the operating lever 2801 connected to the bushing 2802. The mounting base 9 has a through-hole 29 on its side, and the lower end of the vertical shaft 1201 is located within the through-hole 29. The bushing 2802 is circumferentially fixed on the vertical shaft 1201. The operating lever 2801 can rotate at least 90° within the through-hole 29; that is, by reciprocating 90° with the operating lever 2801, the roller 1203 reciprocates above the receiving hole 10 and the wheel rail 3. It should be noted that since the roller 1203 is restricted by the anti-deviation groove 30 when the door is in use, there is no need to lock the operating lever 2801.

[0047] The present invention has been described by way of example in conjunction with the accompanying drawings.
