Description

[0002] With the development of science and technology, the current cabinet air conditioner is not only a device for adjusting indoor temperature, but also has many additional functions. For example, a space for placing mobile devices is arranged at the bottom of some air conditioners. In view of safety, a sliding door structure is arranged for protection. At present, the opening of the sliding door is generally realized by a structure mode of a motor driving a gear and a rack. The motor drives the gear to rotate, and the gear drives the sliding door of the cabinet air conditioner to descend, thereby exposing the space for placing mobile devices, so that the mobile devices can be taken in and out.

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] Please refer to Figures 1 to 18 , the sliding door installation structure and the cabinet air conditioner of an embodiment of the present application aim to solve the technical problems of slow opening and high installation requirements of the existing sliding door. As Figures 1 to 10As shown, the sliding door mounting structure comprises a cabinet 1 and a sliding door 2, wherein the cabinet 1 is provided with a storage cavity 3 with one side open, and the cabinet 1 is in sliding connection with the sliding door 2, and the sliding door 2 can slide in a first direction to close or open the storage cavity 3. The sliding door 2 has two limit positions in the first direction relative to the cabinet 1, i.e. a first position and a second position, and the sliding door 2 can move between the first position and the second position. When in the first position, the sliding door 2 closes the storage cavity 3, in the closed state; and when in the second position, the sliding door 2 opens the storage cavity 3, in the open state. In particular, the sliding door mounting structure further has a resilient opening mechanism 5, two ends of the resilient opening mechanism 5 are connected with the sliding door 2 and the cabinet 1 respectively, and when the sliding door 2 is in the first position, the resilient opening mechanism 5 can provide elastic force to the sliding door 2 to pull it from the first position to the second position, so as to quickly open the sliding door 2 and complete the switching from the closed state to the open state.

[0051] As shown in the drawings, Figures 1 to 3 The cabinet 1 is provided with the above-mentioned storage cavity 3 at the end face provided with the air outlet, and the storage cavity 3 is recessed inward at the bottom of the cabinet 1, and the mobile device can be placed in the storage cavity 3. The cabinet 1 is further provided with a mounting cavity 4 recessed inward from the end face of the cabinet 1 provided with the storage cavity 3, and the mounting cavity 4 is located on the upper side of the storage cavity 3 and the side facing the sliding door 2 is in an open state, and the mounting cavity 4 provides a mounting space for the above-mentioned resilient opening mechanism 5. In particular, the sliding door 2 is square-shaped, and the width thereof corresponds to the cabinet 1, and the length thereof needs to be ensured not to interfere with the air outlet, and the opening of the above-mentioned mounting cavity 4 is located in the shielding area of the sliding door 2, i.e. the sliding door 2 is sufficient to shield the mounting cavity 4 when in the first position and the second position, so that the mounting cavity 4 is not exposed after the sliding door 2 is mounted, which can prevent dust and improve the overall aesthetics. However, the position of the storage cavity 3 can be adjusted according to the needs, for example, close to the air outlet, and the position of the mounting cavity 4 needs to be adjusted according to the position of the storage cavity 3. The above-mentioned cabinet 1 is provided with a sliding guide (not shown in the drawings) for the sliding of the sliding door 2, so as to guide the sliding of the sliding door 2, and the sliding guide also limits the sliding door 2 to move only between the first position and the second position.

[0052] As shown in the drawings, Figures 4 to 6 The resilient opening mechanism 5 is composed of a tension spring assembly, which is installed in the mounting cavity 4 in the first direction (i.e. the vertical direction) and connected with the sliding door 2 and the cabinet 1. Figure 1 and Figure 5As shown, the tension spring assembly comprises a tension spring 8, a first connecting block 9, a second connecting block 10, and a hanging ring 11. The tension spring 8 is a tension spring made of spring steel, with hooks 12 at both ends. The first connecting block 9 is connected to a hanging ring 11 via a round rod, forming a second connecting member. The second connecting block 10 is connected to another hanging ring 11 via another round rod, forming a first connecting member. Thus, the hooks 12 on the tension spring 8 can be hung on the hanging ring 11, forming a detachable connection between the tension spring 8 and the second and first connecting members. Furthermore, the hooks 12 are not limited to the tension spring 8; for example, hanging rings 11 can be provided at both ends of the tension spring 8, while hooks 12 can be provided on the second connecting block 10 and the first connecting block 9, or hooks can be provided on the tension spring 8, the second connecting block 10, and the first connecting block 9. Additionally, as... Figure 6 As shown, the upper end face of the first connecting block 9 is fixed to the cavity wall of the mounting cavity 4 away from the storage cavity 3, while the second connecting block 10 is fixed to the end face of the sliding door 2 facing the mounting cavity 4, and the second connecting block 10 is close to the storage cavity 3. When the tension spring 8 is not under force or only bears the weight of the sliding door 2, the sliding door 2 fully opens the storage cavity 3. The installation of this tension spring assembly only requires sequential connection, without the need for precise positioning, which achieves rapid installation. Moreover, if the operating speed of the sliding door is to be increased, only the tension spring needs to be changed, without changing the overall structural dimensions and specifications, resulting in a high degree of standardization and simple replacement. At the same time, the parts of this tension spring assembly are highly maintainable, have stable long-term operating performance, and will not fail or produce abnormal noise.

[0053] In addition, multiple tension spring assemblies can be provided, and multiple tension spring assemblies can work together to pull the sliding door 2, further improving the opening speed and response speed. The housing is provided with a buffer structure at the corresponding first and second positions to prevent the rapidly moving sliding door 2 from impacting the sliding guide or housing 1, and to avoid structural damage caused by excessive elastic potential energy.

[0054] In some exemplary embodiments, the tension spring 8 can also be an air spring. An air spring has a retractable, sealed container that can be filled with compressed air; it is a spring that utilizes the elasticity of air and is commonly known as an airbag, airbag cylinder, or bellows cylinder. In other exemplary embodiments, the tension spring 8 can also be an elastic rope, with both ends directly attached to the hanging ring 11. Both the air spring and the elastic rope can pull the sliding door open quickly. The tension spring generates greater elastic potential energy, allowing for rapid action and releasing significant power, resulting in a fast response speed.

[0055] When the sliding door 2 is in the first position, it closes the storage cavity 3, in the closed state, the sliding door 2 elongates the tension spring 8, which is in the stretched state, and the elastic force of the tension spring 8 can provide the second connecting block 10 with an upward force, so as to pull the sliding door 2 to start the opening operation instantaneously and quickly. When the sliding door 2 is in the second position, in the open state, the tension spring 8 can only be affected by the gravity of the sliding door 2, and can also be in the stretched state.

[0056] As shown in Figure 3 , Figure 9 and Figure 10 , the sliding door mounting structure further comprises a closing mechanism 6 for completing the closing operation of the sliding door 2, so that the sliding door 2 can be controlled to open or close as required. The mounting cavity 4 also provides sufficient mounting space for the closing mechanism 6, and the closing mechanism 6 is not exposed. Specifically, the closing mechanism 6 is composed of a third connecting block 16, a second pull rope 17, a speed reducer 19, a second motor 18 and a ratchet assembly, which utilizes the bidirectional rotation principle of the ratchet structure. The second motor 18 is provided with a speed reducer 19 to improve the output torque, and the output shaft 23 of the speed reducer 19 serves as the output end of the second motor 18. The ratchet assembly further comprises a shaft sleeve 20, a ratchet 22 and a pawl 21. The shaft sleeve 20 is fixed on the output shaft 23 and can rotate around the output shaft 23 in the axial direction under the drive of the speed reducer 19. The ratchet 22 is sleeved outside the shaft sleeve 20, and its inner diameter is slightly larger than the outer diameter of the shaft sleeve 20, so that it can rotate around the output shaft 23 in the axial direction. The ratchet 22 is provided with a winding groove for winding the second pull rope 17 on the outer periphery. The second pull rope 17 is a traction rope without elasticity, and its lower end extends to the storage cavity 3 and is wound in the winding groove of the ratchet 22. The upper end of the second pull rope 17 extends away from the storage cavity 3 and is provided with the third connecting block 16 at the end. The side wall of the third connecting block 16 can be fixed with the end surface of the sliding door 2. Figure 9 and Figure 10As shown, the inner wall of the ratchet wheel 22 is provided with a ratchet tooth 24, and the pawl 21 is located at the end of the sleeve 20 away from the second motor 18. One end of the pawl 21 is rotationally connected to the sleeve 20 at a certain angle, and the other end extends to the ratchet tooth 24 and cooperates with the ratchet tooth 24. Thus, when the second motor 18 rotates forward (i.e., the output shaft 23 rotates counterclockwise), the pawl 21 abuts against the ratchet tooth 24, which can drive the ratchet wheel 22 to rotate counterclockwise, thereby driving the second pull rope 17 to continue winding around the winding groove of the ratchet wheel 22, and the third connecting block 16 moves downward, and the sliding door 2 also moves downward. When the second motor 18 reverses (i.e., the output shaft 23 rotates clockwise), the pawl 21 cannot act on the ratchet tooth 24, and the ratchet wheel 22 will not rotate. At the same time, when the sliding door 2 is opened, the third connecting block 16 moves upward, and the second pull rope 17 is pulled, partially pushing away the ratchet wheel 22, and the ratchet wheel 22 rotates clockwise. However, at this time, the pawl 21 cannot act on the ratchet tooth 24, so only the ratchet wheel 22 rotates, and the sleeve 20 does not rotate.

[0057] A plurality of the above-mentioned closing mechanisms 6 can be arranged in the mounting cavity 4, and the plurality of closing mechanisms 6 jointly act to close the sliding door 2, ensuring stable and rapid closing. A partition (not shown in the figure) is arranged in the mounting cavity 4, which is arranged in the first direction to separate the mounting cavity 4 into two cavities. The elastic opening mechanism is arranged in one of the cavities, and the closing mechanism is arranged in the other cavity, and the two mechanisms are separated. In addition, the partition can be installed in the mounting cavity 4, and the partition can be removed or installed according to needs, improving the flexibility of use. The second pull rope can no longer be limited to the first direction, and the extension direction can be changed through a fixed pulley, as long as it can be wound around the ratchet wheel 22 and pull the sliding door 2 downward. The position of the ratchet wheel assembly can also be adjusted as needed.

[0058] When the sliding door 2 is in the second position, the sliding door 2 opens the storage cavity 3 and is in the open state. If it is necessary to close the sliding door 2, the second motor can be controlled to act to overcome the action of the tension spring 8, drive the ratchet wheel 22 to rotate, and the second pull rope 17 is partially wound around the ratchet wheel 22 again until the sliding door 2 reaches the first position.

[0059] As Figure 2 , Figure 7 and Figure 8As shown, the sliding door mounting structure further comprises a locking mechanism between the sliding door 2 and the cabinet 1, which can lock the sliding door 2 in the first position or the second position. Specifically, the locking mechanism comprises a first motor (not shown in the figure), two clamping columns 7 and locking holes, wherein the first motor is in the cabinet 1, one end of the two clamping columns 7 is connected with the output end of the first motor, the cabinet 1 is provided with two positioning holes 13, the two clamping columns 7 are installed corresponding to the positioning holes 13, and the two clamping columns 7 can be extended out of the positioning holes 13, i.e. protrude from the cabinet 1, or completely immersed in the positioning holes 13. Correspondingly, the sliding door 2 is provided with four locking holes, which can be divided into two upper locking holes 14 and two lower locking holes 15, the two upper locking holes 14 are located at the two ends of the sliding door 2 in the width direction, and the two lower locking holes 15 are also located at the two ends of the sliding door 2 in the width direction, the two upper locking holes 14 are arranged corresponding to the second position, and the two lower locking holes 15 are arranged corresponding to the first position. Thus, when in the first position, the two clamping columns 7 can be driven by the first motor to protrude out of the positioning holes 13 and be inserted into the lower locking holes 15, so as to be locked in the closed state of the sliding door 2, at this time, no matter how the elastic opening mechanism 5 and the closing mechanism 6 act, the sliding door 2 cannot be moved, and vice versa. When in the second position, the two clamping columns 7 can be driven by the first motor to protrude out of the positioning holes 13 and be inserted into the upper locking holes 14, so as to be locked in the open state of the sliding door 2, at this time, no matter how the elastic opening mechanism 5 and the closing mechanism 6 act, the sliding door 2 cannot be moved. In addition, when in the second position, the tension spring 8 is arranged in the stretched state, the upper locking holes 14 can be omitted, and the sliding door 2 is locked by the tension of the tension spring.

[0060] The locking mechanism is not limited to the clamping column 7 and the sliding door 2, for example, the clamping column 7 can also be inserted into the second connecting block 10 to lock the sliding door 2, at this time, two clamping columns 7 arranged in the mounting cavity 4 are needed, the two clamping columns 7 correspond to the positions of the second connecting block 10 in the first position and the second position respectively, the side wall of the second connecting block 10 is provided with a insertion hole, and the clamping column 7 can be inserted into the insertion slot under the drive of the first motor to limit the second connecting block 10 in the first direction, so as to lock the sliding door 2. In some exemplary embodiments, the locking mechanism can comprise an electromagnetic assembly (not shown in the figure) and a magnet (not shown in the figure), the upper and lower ends of the sliding door can be respectively provided with a magnet, and correspondingly, the cabinet 1 is provided with an electromagnetic assembly corresponding to the magnet on the lower side in the closed state, and another electromagnetic assembly corresponding to the magnet on the upper side in the open state, the two electromagnetic assemblies can attract the magnet in the energized state to achieve the effect of locking the sliding door.

[0061] In order to determine whether the locking mechanism can lock the sliding door 2, the shell 1 is provided with a displacement monitoring device or a position monitoring device to monitor the position of the sliding door 2 in real time, and to determine whether the sliding door 2 is in the first position or in the second position. The displacement monitoring device or the position monitoring device can be electrically connected with the controller in the shell 1, and can send a locking signal when the sliding door 2 is in the first position and the second position. The controller can control the extension of the clamping column 7 according to the locking signal.

[0062] In use of the sliding door, especially when the storage cavity 3 needs to be opened in the closed state, an instruction can be input, which can be input through a remote controller, a mobile terminal or an operation panel on the shell 1. The controller in the shell 1 can control the first motor to drive the clamping column 7 to retract into the shell 1, at which time the sliding door is no longer affected by the locking mechanism and will open the storage cavity 3 under the action of the tension spring assembly, and start the opening operation. Until the sliding door 2 reaches the second position and is in the open state, at which time the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at which time the sliding door 2 is affected by the locking mechanism and is locked in the open state. If it is necessary to close the storage cavity 3, the controller can control the first motor to drive the clamping column 7 to retract into the shell 1 according to the instruction, at which time the sliding door is no longer affected by the locking mechanism, the ratchet assembly is rotated under the action of the second motor, the second tension rope is wound around the ratchet 22, and the sliding door is moved against the action of the tension spring until the sliding door 2 reaches the first position. At this time, the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at which time the sliding door 2 is affected by the locking mechanism and is locked in the closed state.

[0063] In some example embodiments, as Figure 11 and Figure 12As shown, the elastic opening mechanism comprises a compression spring assembly which is no longer stretched but compressed. Specifically, the compression spring assembly comprises a detachable cylinder 27, a pressing member, a compression spring 28 and a sliding block 29. The cylinder 27 is a square tub structure, one end of which is provided with an opening 30. The end of the cylinder 27 far from the opening 30 is closed, and the cylinder 27 is arranged in the mounting cavity 4 along a first direction, with the opening 30 at the end far from the storage cavity 3. The bottom of the cylinder 27 is fixed to the cavity wall of the mounting cavity 4 close to the storage cavity 3, forming a stable fixation. The cylinder 27 provides a mounting space for the sliding block 29 and the compression spring 28, so that the three become an integral whole. The sliding block 29 and the compression spring 28 are mounted in the cylinder 27. The compression spring 28 is a compression spring made of spring steel, located at the cylinder bottom, and the sliding block 29 is located at the side close to the opening 30. The sliding block 29 needs to press the compression spring 28 when moving towards the cylinder bottom. The shape of the sliding block 29 matches the cross section of the cylinder 27 to slide along the length direction (first direction) of the cylinder 27. The inner wall of the cylinder 27 is provided with a recessed guide groove, and the edge of the sliding block 29 is provided with a protruding guide protrusion. The guide protrusion and the guide groove are correspondingly inserted to further guide the sliding of the sliding block 29. The pressing member comprises an integrated pressing rod 26 and a fourth connecting block 25. The pressing member is also arranged above and below the cylinder 27, i.e. along the first direction. The side wall of the fourth connecting block 25 is fixed to the sliding door 2, and the outer dimensions of the fourth connecting block 25 are larger than the opening area of the opening 30 to avoid the fourth connecting block 25 also inserted into the cylinder 27. The pressing rod 26 is a round rod, the upper end of which is connected to the fourth connecting block 25, and the lower end of which can extend into the cylinder 27 to press against the sliding block 29 to press the compression spring. Notably, the cylinder 27, the sliding block 29 and the compression spring 28 constitute a spring cylinder, which is a separate part from the pressing member, and is separated from the sliding door 2 and the cabinet 1. There is no need to connect the two, and the two do not need to be precisely matched. Only the installation positioning needs to be accurate, and the installation is simple. There is only one sliding block in the whole structure, which can be lubricated by adding lubricating oil in the guide groove regularly, and the maintenance is simple. There is no other transmission device, and there will be no big noise problem in long-term operation. The limiting structure is arranged at the end far from the opening 30 of the guide groove to limit the sliding block from continuously sliding to the cylinder bottom.

[0064] In some example embodiments, the compression spring 28 can also use elastic blocks or air springs, which can be deformed by pressing. The deformation can provide power for the opening of the sliding door 2. The elastic blocks or air springs can push the sliding door to open, but the elastic potential energy generated by the compression spring is greater, which can quickly act and release a large amount of power, with a fast response speed.

[0065] When the sliding door 2 is in the first position, the sliding door 2 closes the storage cavity 3, the extrusion piece is in the lowest position, the extrusion spring is extruded, the compression spring is in the compressed state, the elastic force of the compression spring can provide an upward force to the fourth connecting block, so that the sliding door 2 can be pushed upward to start the opening operation instantaneously and quickly, especially after the locking mechanism is released. When the sliding door 2 is in the second position, the compression spring 28 can only be subjected to the gravity of the sliding door 2, or the lower end of the extrusion piece is separated from the sliding block, that is, the compression spring 28 is not subjected to the force. When it is needed to close the storage cavity 3, the extrusion piece falls from the highest position, the ratchet assembly is rotated under the action of the second motor, the second pull rope is wound on the ratchet 22, and the sliding door 2 is moved against the action of the compression spring 28 until the sliding door 2 reaches the first position. Similarly, in the first position and the second position, the position of the sliding door 2 can be locked by the locking mechanism. In addition, if it is needed to improve the running speed of the sliding door 2, the compression spring 28 with the corresponding size can be changed, without the need to replace the sliding block and other mechanisms, with strong commonality, high standardization degree, and simple replacement.

[0066] In use of the sliding door, especially when it is needed to open the storage cavity 3, a command can be input, the controller in the shell 1 can control the first motor to drive the clamping column 7 to act, at this time, the sliding door is no longer subjected to the action of the locking mechanism, and the storage cavity 3 is opened under the action of the compression spring assembly. Until the sliding door 2 reaches the second position, at this time, the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at this time, the sliding door 2 is subjected to the action of the locking mechanism and is locked in the open state. If it is needed to close the storage cavity 3, the controller can control the first motor to drive the clamping column 7 to act according to the command, at this time, the sliding door is no longer subjected to the action of the locking mechanism, the ratchet assembly is rotated under the action of the second motor, the second pull rope is wound on the ratchet 22, the sliding door is moved against the action of the compression spring until the sliding door 2 reaches the first position. At this time, the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at this time, the sliding door 2 is subjected to the action of the locking mechanism and is locked in the closed state. As known from the above, the compression spring stores a large elastic potential energy, and can quickly act after receiving the opening signal, and releases a large capacity at the same time, with a quick response speed.

[0067] In some example embodiments, as Figures 13 to 18As shown, the elastic opening mechanism is composed of a rotating elastic body 31 capable of generating torsion, and in order to realize the conversion of torsion into pulling force on the sliding door, it is also necessary to have a first pulling rope 37, a first housing and a rotating member 36. Specifically, the rotating elastic body 31 can be a torsion spring or a volute spring, and in this example, a volute spring, also known as a clock spring, is used, which is a spring with one end fixed and the other end subjected to a torque, and under the action of the torque, the spring material produces bending elastic deformation, causing the spring to produce torsion in the plane, and the size of the deformation angle is proportional to the torque. The volute spring is processed from a spring sheet and is made of metal, but is not limited to using steel or other metals, and the whole is in the shape of a vortex, having two ends, namely a first end 32 in the middle position and a second end 33 at the outer periphery. The first end 32 and the second end 33 are both flat plates, the first end 32 extends inward along the radial direction, and the second end 33 extends outward along the radial direction.

[0068] As shown in Figure 15 , Figure 16 and Figure 18 , the first housing is a hollow structure, including a split bottom shell 34 and an upper cover 35, the upper cover 35 can be covered on the bottom shell 34 to form the installation space of the volute spring, and the volute spring needs to be installed in the first housing. The inner wall of the first housing (i.e. the inner wall of the bottom shell 34) is provided with a first fixing part 39, which is provided as two protruding tendons, the two tendons are arranged in parallel, and a first limiting groove is formed between the two tendons; the second end 33 of the volute spring needs to be arranged corresponding to the first fixing part 39, i.e. the free end of the second end 33 can be inserted into the first limiting groove to position the second end 33 in the circumferential direction. The upper cover 35 is provided with a mounting hole, and the rotating member 36 is rotatably mounted at the mounting hole of the upper cover 35, so that it can rotate around its own axis on the upper cover 35, one end of the rotating member 36 extends into the first housing and is connected with the first end 32 through a fixing position 40, so that the rotating member 36 can drive the first end 32 to rotate, and the other end of the rotating member 36 is outside the first housing. The fixing position 40 is specifically two parallel flat plates, a second limiting groove is formed between the two flat plates, and the free end of the first end 32 can be inserted into the second limiting groove to relatively fix the first end 32 and the rotating member 36. The part of the rotating member 36 outside the first housing is also processed with a winding groove, and the first pulling rope 37 is a non-elastic traction rope, one end of which is fixed in the winding groove and partially wound on the winding groove, and the other end of the first pulling rope 37 is fixed on the fifth connecting block 38. The first housing is fixed on the cavity wall of the installation cavity 4 away from the storage cavity 3, and the first pulling rope 37 extends downward, and the side wall of the fifth connecting block is fixed with the sliding door 2. When the sliding door 2 completely opens the storage cavity 3, the volute spring is only subjected to the gravity of the sliding door 2, or is still in the force storage state.

[0069] When the sliding door 2 is in the first position, the sliding door 2 closes the storage cavity 3, the scroll spring generates a shape plate, the scroll spring is in a force storage state, and there is a torsion force, the force of which can be provided to the fifth connecting block to provide an upward force, so that the fifth connecting block is pulled upward when opening, especially after the locking mechanism is released, and part of the first pull rope is also rewound on the rotating member, and the sliding door 2 starts the opening operation instantaneously and quickly. When the sliding door 2 is in the second position, the scroll spring is only subjected to the gravity of the sliding door 2. When it is needed to close the storage cavity 3, the ratchet assembly is rotated under the action of the second motor, the second pull rope is pulled to be wound on the ratchet 22, and the sliding door 2 is moved upward against the action of the scroll spring until the sliding door 2 reaches the first position. In addition, if it is needed to improve the running speed of the sliding door 2, the scroll spring can be changed, and the overall structure size does not need to be changed, and the standardization degree is high and the replacement is simple. The first pull rope can no longer be limited to the first direction, and the extension direction can be changed through a fixed pulley, as long as the scroll spring can be deformed and the sliding door 2 can be pulled upward, and the position of the scroll spring can be adjusted as needed.

[0070] When the sliding door is used, especially when it is needed to open the storage cavity 3, a command can be input, the controller in the shell 1 can control the first motor to drive the clamping column 7 to act, at this time, the sliding door is no longer subjected to the action of the locking mechanism, and the sliding door is moved upward under the action of the scroll spring to open the storage cavity 3. Until the sliding door 2 reaches the second position, at this time, the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at this time, the sliding door 2 is subjected to the action of the locking mechanism and is locked in the open state. If it is needed to close the storage cavity 3, the controller can control the first motor to drive the clamping column 7 to act according to the command, at this time, the sliding door is no longer subjected to the action of the locking mechanism, the ratchet assembly is rotated under the action of the second motor, the second pull rope is pulled to be wound on the ratchet 22, and the sliding door is moved downward against the action of the scroll spring until the sliding door 2 reaches the first position. At this time, the displacement monitoring device monitors the movement data of the sliding door 2, and the controller can control the first motor to drive the clamping column 7 to extend according to the monitoring data, at this time, the sliding door 2 is subjected to the action of the locking mechanism and is locked in the closed state. As known from the above, the scroll spring can store a large amount of elastic potential energy, and after receiving the opening operation signal, the scroll spring can quickly act and release a large amount of energy, so that the sliding door 2 can be quickly switched from static to motion, and the action speed is fast

[0071] The application further provides an air conditioner cabinet, comprising the sliding door mounting structure, and possibly further comprising a mobile device (not shown in the figure). The mobile device can be an independent device, and is placed in the storage cavity 3 and can be quickly in and out after starting operation, regardless of whether the mobile device is associated with the air conditioner cabinet. The cabinet 1 is provided with a controller, which is electrically connected with the first motor and the second motor. In the specific use process, when the mobile device needs to be moved out of the storage cavity 3, an instruction can be sent to the controller. The controller controls the sliding door locking mechanism to be unlocked, the sliding door to be opened, and the sliding door to be locked again in sequence according to the signal. Then the mobile device can be automatically moved out under the control of the controller or manually taken out. After the mobile device is moved out for a preset time, the controller can control the locking mechanism to be unlocked, the sliding door to be closed, and the sliding door to be locked again in sequence, so as to avoid dust entering the storage cavity 3. When the mobile device needs to return to the storage cavity 3, the user can send an instruction to the controller. The controller controls the sliding door locking mechanism to be unlocked, the sliding door to be opened, the sliding door to be locked, the mobile device to enter the storage cavity 3, the locking mechanism to be unlocked, the sliding door to be closed, and finally the sliding door to be locked in sequence according to the signal, so as to complete the return of the mobile device to the cabinet 1.
