Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a cabinet sliding door structure and a cabinet. Background Art

[0002] Existing cabinet sliding door structures usually use a rack and pinion transmission mechanism, for example:

[0003] The patent with publication number CN117328761A discloses a motion mechanism of a cabinet sliding door, wherein the motion mechanism has two and the two motion mechanisms are respectively arranged on the upper and lower sides of the large door panel (i.e., the sliding door), and includes a motor, a motor driving gear, a transmission rack and a stabilizing component, wherein the transmission rack is provided with a fixed block connected to the large door panel; the motor driving gear drives the transmission rack to rotate, and the transmission rack drives the fixed block and the large door panel connected to the fixed block to reciprocate; wherein the stabilizing component is connected to the transmission rack to ensure the stability of the transmission rack operation. Specifically, the stabilizing component includes a number of thrust pins fixedly mounted on the full circle transmission rack, three driven gears (the inner ring of which is provided with helical teeth that cooperate with the thrust pins) and a gear meshing with the driven gear. The three auxiliary gears are engaged. During the operation of the transmission rack, the thrust pin on the upper end face of the transmission rack also synchronously drives the three driven gears to rotate. The damping is increased by the meshing transmission of the three driven gears and the flexible transmission rack, and the meshing transmission of each driven gear and the corresponding auxiliary gear, so as to avoid warping or shaking during the operation of the transmission rack and ensure that the transmission rack (and the door panel) can move stably around the arc; in addition, the rotation of the transmission rack and the driven gear are both rotations with a certain resistance to further increase the stability of the rotation; finally, the motion mechanism realizes the "zero gap" closure of the door panel movement by setting a variable track part, and the irregular track operation trajectory is determined by the program set by the main board, and the reading speed and cycle set by the main board can determine the travel range.

[0004] It can be seen that the existing gear rack transmission mechanism faces the problem of unstable operation and poor operation accuracy of sliding doors. Although certain measures have been taken to try to solve this problem, such as using the above-mentioned stabilizing component to make the transmission rack run stably, or using the above-mentioned rotation method with resistance to increase the stability of the transmission rack and the driven gear rotation, or using a variable trajectory part to achieve the accuracy of the door panel movement position, such solutions result in more transmission parts or complex operation trajectories, high subsequent maintenance requirements and great difficulty, and cannot guarantee the long-term stability and accuracy of the system, and still fail to fundamentally solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a cabinet sliding door structure, which solves the problems of unstable operation and poor operation precision of the cabinet sliding door in the prior art.

[0006] According to an embodiment of the present invention, a cabinet sliding door structure is provided between a cabinet housing and an air duct assembly within the cabinet housing and is used to open and close an air vent on the cabinet housing. The structure includes:

[0012] On the other hand, according to an embodiment of the present invention, a cabinet is also provided, which includes the above-mentioned cabinet sliding door structure.

[0013] The technical principle of the present invention is as follows: the slide rail assembly, drive assembly, limit guide mechanism and sliding door are all arranged in the preset sliding path direction or cooperate with each other to achieve stability in the sliding door operation process and accuracy of the operation trajectory; specifically, the sliding door slides along the preset sliding path and is attached to the inner side of the cabinet shell and cooperates with the air outlet, that is, the preset sliding path is arranged to fit the inner side of the cabinet shell and it also passes through the air outlet, and the shape of the sliding door is also designed to fit the cabinet shell, so that the opening and closing process of the sliding door to the air outlet is as seamless as possible to ensure accuracy; the slide rail assembly is fixedly connected to the sliding door and is arranged along the preset sliding path direction, that is, the slide rail assembly has a certain length and its entirety is arranged along the preset sliding path direction, combined with the above-mentioned arrangement of the sliding door, thereby ensuring the sliding door, the slide rail assembly and the sliding The door-connected part and the rest of the slide rail assembly are always located on a preset sliding path; and the drive of the drive assembly is also directional. Specifically, the drive assembly is connected to the slide rail assembly and is used to drive the slide rail assembly to slide along the preset sliding path direction, ensuring that the slide rail assembly and the sliding door have a certain operating trajectory; in addition, the limiting guide mechanism is connected to the air duct assembly and is slidably connected to the slide rail assembly, and is used to limit the sliding of the slide rail assembly along the preset sliding path direction. That is to say, the limiting guide mechanism is also arranged along the preset sliding path direction, which limits the sliding of the slide rail assembly with a certain length within it, further ensuring that the slide rail assembly and the sliding door operate in a determined operating trajectory; plus there are two motion components and they are distributed at both ends of the sliding door for connection so that the sliding door is evenly stressed, ultimately ensuring the stability and accuracy of the operation.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Stable Operation. The rail assembly, limit guide mechanism, sliding door, and drive assembly are all arranged and always located in the preset sliding path direction, ensuring that the rail assembly and sliding door have a defined operating trajectory and always operate within the defined operating trajectory, ensuring stable and accurate operation. The two sets of motion components are symmetrically arranged at both ends of the sliding door, so that the sliding door is evenly stressed, further ensuring stable and accurate operation.

[0016] 2. High precision.

The shape of the sliding door is also designed to fit the cabinet housing. In addition, the driving direction of the slide rail assembly, the limit guide mechanism, the sliding door, and the drive assembly are all arranged in the direction of the preset sliding path. Therefore, except for the drive assembly, the remaining parts of the cabinet sliding door structure of this application only occupy the space where the preset sliding path is located as much as possible. This design is relatively space-saving.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-11As shown, the embodiment of the present invention proposes a cabinet sliding door structure, which is arranged between the cabinet shell 100 and the air duct component 300 in the cabinet shell 100 and is used to open and close the air outlet on the cabinet shell 100. The cabinet sliding door structure includes a sliding door 400 and a motion component; it should be noted that the air duct component 300 is arranged inside the cabinet shell 100 along the length direction of the cabinet, and its position corresponds to the air outlet. In addition, the air outlet refers to the cabinet air outlet that can deliver cold air or hot air required by the user. The air outlet is generally arranged at the upper end of the cabinet, that is, it has a certain distance from the bottom of the cabinet to achieve more effective air supply. At this time, in order to reduce weight, the height of the sliding door 400 only needs to correspond to the height of the air outlet, and the width of the sliding door 400 is just It is advisable to well shield the air outlet. It should be noted that the sizes of the sliding door 400 in each embodiment of the present invention are all based on this standard; the sliding door 400 slides along a preset sliding path and is attached to the inner side of the cabinet shell 100 and cooperates with the air outlet. At this time, combined with the above-mentioned restrictions on the height and width of the sliding door 400, it can be seen that the preset sliding path is arranged to fit the inner side of the cabinet shell 100 and it also passes through the air outlet, and the shape of the sliding door 400 is also designed to fit the cabinet shell 100, so that the opening and closing process of the sliding door 400 to the air outlet can be seamlessly connected as much as possible to ensure accuracy; of course, the seamless connection is not seamless in the strict sense, and the objectively existing small gaps can be filled by corresponding gaps on the inner side of the cabinet shell 100. Narrow plates are provided at both ends of the air vent to slide and fit with the outer side of the sliding door 400 to further narrow the gap; preferably, in order to save space and make effective sliding, the preset sliding path extends from one end of the air vent to the other end of the air vent and continues to extend a certain distance to the side of the air vent, that is, the sliding door 400 stroke is approximately equal to the length of the corresponding air vent position on the sliding path to achieve the opening and closing of the air vent, and when the sliding door 400 moves to the position where the air vent is fully opened, the sliding door 400 is hidden on the inner side of the cabinet shell 100 close to the air vent; the sliding door 400 has a certain weight, and in order to make it evenly stressed for stable sliding, there are two moving components and they are distributed at both ends of the sliding door 400 for connection, and the two ends here specifically refer to the upper and lower ends of the sliding door 400. The upper and lower ends of the sliding door 400 are fixedly connected to each other, and the driving assembly and the limiting guide mechanism are provided. The sliding rail assembly is fixedly connected to the sliding door 400 and is arranged along the preset sliding path direction. That is, the sliding rail assembly has a certain length and is arranged along the preset sliding path direction as a whole. Combined with the arrangement of the sliding door 400, it is ensured that the sliding door 400, the portion of the sliding rail assembly connected to the sliding door 400, and the rest of the sliding rail assembly are always located on the preset sliding path. The driving assembly is connected to the sliding rail assembly and is used to drive the sliding rail assembly to slide along the preset sliding path direction. That is, the driving of the driving assembly is also directional, ensuring that the sliding rail assembly and the sliding door 400 have a fixed running trajectory.The position-limiting guide mechanism is connected to the air duct assembly 300 and is slidably connected to the slide rail assembly, and is used to limit the slide rail assembly from sliding along a predetermined sliding path. In other words, the position-limiting guide mechanism is also arranged along the predetermined sliding path, and it limits the slide rail assembly of a certain length to a position within the predetermined sliding path, further ensuring that the slide rail assembly and the sliding door 400 operate within a predetermined trajectory.

[0034] In the present invention, the slide rail assembly, the drive assembly, the limit guide mechanism, and the sliding door 400 are arranged or coordinated with each other in a predetermined sliding path direction to achieve stability and accuracy of the sliding door 400 during operation; specifically, as follows:

[0035] On the one hand, the operation is stable. The driving direction of the slide rail assembly, the limiting guide mechanism, the sliding door 400, and the drive assembly are all arranged and always located in the preset sliding path direction, ensuring that the slide rail assembly and the sliding door 400 have a defined operating trajectory and always operate within the defined operating trajectory, ensuring stable and accurate operation. The two sets of motion components are symmetrically arranged at both ends of the sliding door 400, so that the sliding door 400 is evenly stressed, further ensuring stable and accurate operation.

[0036] On the other hand, the high precision is achieved. The determined running trajectory ensures the precision of the operation, and the sliding door 400 conforms to the shape of the cabinet housing 100 and the sliding operation mode of the sliding door 400 slidingly attached to the inner side of the cabinet housing 100, which together make the opening and closing process of the sliding door 400 to the air outlet as seamless as possible, further ensuring the precision of the operation.

[0037] Finally, space is saved. The preset sliding path is arranged to fit the inside of the cabinet housing 100 and passes through the air vent. The shape of the sliding door 400 is also designed to fit the cabinet housing 100. In addition, the driving direction of the slide rail assembly, the limiting guide mechanism, the sliding door 400, and the drive assembly are all arranged in the direction of the preset sliding path. Therefore, except for the drive assembly, the remaining parts of the cabinet sliding door structure of the present application only occupy the space where the preset sliding path is located as much as possible, which is a relatively space-saving design.

[0038] like Figure 4 、 Figure 7 as well as Figures 9-11As shown, according to another embodiment of the present invention, in the cabinet sliding door structure, the slide rail assembly includes a slide rail 510 and a connecting portion 520; the slide rail 510 is arranged along a preset sliding path direction and is slidably connected to the limit guide mechanism. At this time, in order to stabilize the sliding door 400 in a determined running track, preferably, one end of the slide rail 510 is located at one end of the sliding door 400, and the slide rail 510 extends from one end of the sliding door 400 along the width direction of the sliding door 400 to the other end of the sliding door 400 and continues to extend, and when the sliding door 400 completely blocks the air outlet, the other end of the slide rail 510 still remains in contact with the limit guide mechanism. More preferably, when the sliding door 400 completely blocks the air vent, the other end of the slide rail 510 is located at the end of the limiting guide mechanism away from the air vent. In this case, the slide rail 510 is longer and the structure is more stable. The connecting portion 520 is connected between the slide rail 510 and the sliding door 400. One end of the connecting portion 520 is fixedly connected to the sliding door 400 and the other end is connected to the drive assembly. In order to ensure the stability of the structure, the connecting portion 520 preferably extends from one end of the slide rail 510 to the other end of the slide rail 510, and the connecting portion 520 has a contact surface fixedly connected to the sliding door 400, and the contact surface has a certain width. The above arrangement forms a sliding clearance space 530 between the slide rail 510 and the sliding door 400, so that the portion of the slide rail 510 corresponding to the sliding door 400 can also slide smoothly in the limiting guide mechanism, thereby ensuring that the preset sliding path can pass through the air vent and is the shortest.

[0039] Further, such as Figure 10-11 As shown, in order to ensure the accuracy of the running trajectory, the slide rail assembly also includes a stopper 540, which is arranged at one end of the slide rail 510 along its length direction, and is blocked at one end of the corresponding limiting guide mechanism after the air outlet is fully opened.

[0040] like Figure 4 、 Figure 6 as well as Figures 9-11As shown, according to another embodiment of the present invention, in the cabinet sliding door structure, the limiting guide mechanism includes a limiting guide frame 610 and a slide groove 620; one end of the limiting guide frame 610 is connected to the air duct assembly 300. Preferably, the limiting guide frame 610 is connected to the air duct assembly 300 close to the side of the air outlet. This arrangement makes full use of the space inside the cabinet shell 100. Specifically, the general cabinet shell 100 has a relatively flat outline in the front and back and has an outward convex arc on the left and right sides (the side where the air outlet is located is designated as the front of the cabinet, and accordingly, a back cover is provided at the back of the cabinet). Therefore, the left and right sides of the space enclosed by the cabinet shell 100 and the air duct assembly 300 are relatively large, and it is also more convenient to place the limiting guide frame 610 here. The slide groove 620 has multiple slide grooves 620 and the multiple slide grooves 620 are arranged in sequence along the preset sliding path direction at the other end of the limiting guide frame 610. Specifically, since the sliding door 400 has a certain weight, each slide groove 620 is preferably extended in the vertical direction and opened upward. At this time, when the slide rail 510 is stationary or sliding in the slide groove 620, the slide groove 620 can bear part of the weight of the sliding door 400, making the structure more stable; and also because the sliding door 400 has a certain weight, in order to reduce the sliding friction between the slide rail 510 and the slide groove 620 so that the slide rail 510 can move more easily and smoothly. Sliding in the slide groove 620, a guide wheel 630 rotatably connected to the limiting guide frame 610 is provided between two adjacent slide grooves 620, and the slide rail 510 slides in the slide groove 620 to drive the guide wheel 630 to rotate, and the rotation of the guide wheel 630 converts the sliding friction part into rolling friction, thereby greatly reducing the friction between the slide rail 510 and the slide groove 620; in order to enhance the limiting guiding effect of the guide wheel 630 on the slide rail 510, the peripheral side of the guide wheel 630 can be designed as a groove (which can be named as a guide wheel groove 631), and the guide wheel groove 631 is also arranged along the preset sliding path direction. The above arrangement ensures that the slide rail 510 is always limited along the preset sliding path when moving on the slide groove 620 and the guide wheel 630, and the guide wheel 630 converts the sliding friction on the slide rail 510 into rotational friction, thereby better achieving the guiding function and allowing the slide rail 510 to run smoothly under load conditions, thereby ensuring the stability of the operation of the slide rail 510 and the sliding door 400.

[0041] Further, such as Figure 4 、 Figure 9 and Figure 11 As shown, the cabinet sliding door structure further includes a sealing plate 800, which is arranged along the circumference of the sliding door 400 and extends into the interior of the cabinet. A clearance notch 810 is opened at a corresponding position on the sealing plate 800 for the connection portion 520 to pass through. The other side of the sealing plate 800 opposite to the clearance notch 810 abuts against the side wall of the air duct assembly 300 after the air outlet is closed. Specifically:

[0042] As can be seen from the above, the left and right spaces within the space enclosed by the cabinet shell 100 and the air duct assembly 300 are larger, and a limited guide mechanism has been set in the enclosed space on one side. At this time, in the enclosed space on the other side (and close to the air outlet), the shell of the air duct assembly 300 can adaptively extend and abut against the inner side of the cabinet shell 100, and the extended portion of this air duct assembly 300 has a fitting surface that abuts against the corresponding side of the sealing plate 800. When the sliding door 400 completely covers the air outlet, the sealing plate 800 and the extended portion of the air duct assembly 300 abut against this fitting surface to further reduce the air outlet. A gap can exist; in addition, a duct slot that cooperates with the corresponding side of the closing plate 800 can be provided on this fitting surface, so that the closing plate 800 can be partially inserted into the duct slot when the air outlet is blocked, so as to improve the accuracy of the movement trajectory; or, a duct slot that cooperates with the corresponding side of the air duct assembly 300 can be provided at the position of the closure plate 800 corresponding to this fitting surface, so that the air duct assembly 300 can be partially inserted into the duct slot when the air outlet is blocked. At this time, not only the accuracy of the movement trajectory can be improved, but also the air duct assembly 300 can bear part of the weight of the sliding door 400 to improve the stability of the structure. The clearance gap 810 is specifically located on the closing plate 800 near the limiting guide mechanism, and the clearance gap 810 is also on a preset sliding path to allow the connecting portion 520 to pass through, so as to better achieve the limitation and fixation of the connecting portion 520; more specifically, the clearance gap 810 is in the sliding clearance space 530 formed between the slide rail 510 and the sliding door 400. When the sliding door 400 slides to open the air outlet, preferably, the corresponding slide groove 620 on the closing plate 800 always slides and sticks to the side of the slide groove 620 away from the air duct assembly 300, and stops sliding when the block 540 abuts against the inner side of the closing plate 800. At this time, the air outlet is fully opened, and most of the weight of the sliding door 400 is borne by the slide groove 620.

[0043] like Figure 3 、 Figure 4 as well as Figures 9-11As shown, according to another embodiment of the present invention, in the cabinet sliding door structure, the driving assembly includes a rotary driver 710 and a connecting rod 720. The selection of the rotary driver 710 is relatively flexible, and devices with a rotary driving function such as a rotary cylinder, a rotary motor, and a rotary motor can be used; the rotary driver 710 is fixedly connected to the air duct assembly 300. Specifically, in order to save space, the two rotary drivers 710 are symmetrically arranged on the outer side of the upper base plate or the lower base plate of the air duct assembly 300; one end of the connecting rod 720 is fixedly connected to the output shaft of the rotary driver 710 and the other end is connected to the connecting part 520. The end of the connecting rod 720 connected to the connecting part 520 rotates along the preset sliding path direction, that is, the connecting rod 720 transmits the rotational motion of the rotary driver 710 to the connecting part 52 0, the connecting part 520 drives the slide rail 510 and the sliding door 400 to rotate along the preset sliding path direction, and the connecting rod 720 here also bears part of the weight of the sliding door 400; at this time, in order to further save space, the output shaft of the rotary driver 710 is arranged in the vertical direction, and the connecting rod 720 is arranged in the horizontal direction and is in the shape of a flat plate with a certain thickness, and the end of the connecting rod 720 connected to the connecting part 520 is attached to the connecting part 520. Based on this arrangement, the part of the air duct assembly 300 located within the rotation range of the connecting rod 720 is provided with a rotation avoidance gap 310, and the parts of the air duct assembly 300 located at both ends of the rotation avoidance gap 310 can limit the connecting rod 720, so as to control the rotation of the connecting rod 720 within the preset angle range while saving space, thereby greatly improving the accuracy of the running trajectory. This embodiment adopts a driving method of a rotary driver 710 and a connecting rod 720, and controls the driving direction to extend along a circular arc. At this time, the preset sliding path is also on a circular arc. Under this driving method, on the one hand, the transmission effect of the connecting rod 720 is more stable and effective, making the sliding more stable and smooth. On the other hand, the motion range of the connecting rod 720 is easier to control, making the sliding trajectory more precise. Finally, the arc-shaped sliding path is more in line with the shape of the common cabinet housing 100, so that the opening and closing of the air outlet by the sliding door 400 can be as seamless as possible, thereby saving space while further improving the accuracy of the opening and closing of the air outlet.

[0044] Based on the above scheme, if Figure 3-Figure 5 as well as Figures 9-11As shown, in order to better fix and further control the rotation range, the rotary driver 710 is fixedly connected to the air duct assembly 300 via a mounting bracket. The mounting bracket has a rotation limit space 731. The end of the connecting rod 720 connected to the output shaft of the rotary driver 710 is rotationally limited within the rotation limit space 731. Preferably, the mounting bracket has a base 732. One end of the base 732 is fixedly connected to the outer side of the upper base plate or the lower base plate of the air duct assembly 300. The other end of the base 732 is provided with a mounting step 733. The mounting step 733 has a corner and forms the rotation limit space 731, and the rotation limit space 731 includes the corner. The end of the mounting step 733 away from the base 732 is fixedly connected to the rotary driver 710. The output shaft of the rotary driver 710 extends in the vertical direction. Enter the rotation limit space 731; the connecting rod 720 is fixedly mounted on the output shaft of the rotation driver 710 through a sleeve 734, and the sleeve 734 is arranged along the length direction of the output shaft and its vertical axis coincides with the vertical axis of the output shaft, and the base 732 is provided with a limiting round block 735 that cooperates with the sleeve 734, that is, one end of the sleeve 734 is rotatably mounted on the limiting round block 735; the length direction of the connecting rod 720 is perpendicular to the output shaft of the rotation driver 710. Under the above-mentioned preferred arrangement, on the one hand, the rotation of the output shaft of the rotary driver 710 is controlled in the vertical direction by the sleeve 734 and the limiting circle 735, thereby avoiding the connecting rod 720 that indirectly bears the weight of the sliding door 400 being directly connected to the output shaft and affecting the rotation accuracy of the output shaft, thereby making the output of the rotary driver 710 more stable and ensuring the stability of the entire motion assembly; on the other hand, the connecting rod 720 expands the rotation radius of the rotary driver 710 so that when one end of the connecting rod 720 rotates along the preset sliding path direction, it will be blocked by the parts of the mounting platform 733 located at both ends of the corner, which further controls the movement of the connecting rod 720 within the preset angle range, thereby ensuring the accuracy of the movement.

[0045] On the other hand, Figure 1-Figure 3 As shown, an embodiment of the present invention further proposes a cabinet, including a cabinet sliding door structure in any of the above embodiments, and having the advantages of the cabinet sliding door structure in any of the above embodiments.

[0046] In this embodiment (taking the sealing plate slot and the rotating motor as an example), when in use:

[0047] Initial state: The sliding door 400 is in a state of completely covering the air outlet. At this time, the air duct assembly 300 is partially stuck in the sealing plate slot, and the weight of the sliding door 400 is borne directly by the air duct assembly 300 or indirectly through the sliding slot 620 and the connecting rod 720.

[0048] Opening the vents: The cabinet unit is turned on (started), which activates the rotary motor. The rotary motor drives the connecting rod 720 via the sleeve 734, which in turn drives the slide rail 510 to slide within the slide groove 620. The sliding of the slide rail 510 drives the guide wheel 630 to rotate. The rotation of the guide wheel 630 in turn provides assistance to the movement of the slide rail 510, allowing the slide rail 510 to more easily and smoothly drive the sliding door 400 in the direction of opening the vents. The presence of the sliding clearance space 530 also allows the portion of the slide rail 510 corresponding to the sliding door 400 to slide smoothly within the slide groove 620. The sliding stops when the stopper 540 abuts the inside of the sealing plate 800. At this point, the connecting rod 720 is also blocked by the portion of the air duct assembly 300 at one end of the rotational clearance notch 310 and the portion of the mounting platform 733 at one end of the corner, stopping its rotation. The rotary motor then turns off. The vents are now fully open, delivering the desired cool or hot air.

[0049] To shield the air vents: To shut down the cabinet (shutdown), the rotary motor is activated and set to rotate in the opposite direction to when the cabinet was turned on. The rotation of the rotary motor, through the transmission action of the sleeve 734, the connecting rod 720, and the slide rail 510, drives the sliding door 400 in the direction of shielding the air vents. The sliding stops when part of the air duct assembly 300 is locked into the cover plate slot. At this time, the connecting rod 720 is also blocked by the part of the air duct assembly 300 on the other side of the rotation avoidance gap 310 and the part of the mounting platform 733 on the other side of the corner, stopping the rotation of the rotary motor. The rotary motor is then turned off. The air vents are now completely shielded, and the cabinet returns to its initial state.
