Description

Technical Field

[0001] This invention relates to the field of drawer organization technology, specifically to a drawer with a cover and a cabinet using the same. Background Technology

[0002] In modern, fully-furnished apartments, various types of table and cabinet furniture are used. These furniture pieces typically have drawers installed inside for storing various small items.

[0003] However, most drawers do not have a sealing lid, which is inconvenient for storing items that need to be kept clean and dry. Therefore, some drawers with lids have appeared on the market. Most drawers with lids on the market are made by adding a lid to the upper surface of the original drawer body through a horizontal sliding mechanism. The lid can be slid open or closed along the direction of the drawer's extension. The problems with this drawer with a cover are: (1) In order to maintain the smoothness of the cover when it is pushed and pulled along the extension direction of the drawer, the fit between the cover and the upper surface of the drawer body is poor, which means that dust and moisture can still enter the drawer through the gap between the cover and the upper surface of the drawer body, making it difficult to meet the requirements of maintaining high cleanliness and high dryness of the drawer interior space; (2) The cover and the upper surface of the drawer body are rigidly connected by a horizontal push-pull mechanism. The horizontal push-pull mechanism is prone to warping and deformation under external force during the opening and closing of the cover, which will affect the smoothness of the cover when it is opened or closed over time; (3) The cover and the upper surface of the drawer body are rigidly connected by a horizontal push-pull mechanism. During the transportation of the drawer, the cover is prone to sliding back and forth relative to the drawer body, which poses a risk of the cover hitting and damaging the inner wall of the drawer body. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a drawer with a cover and a cabinet using it. The drawer with a cover of this invention has the cover fixedly installed on the upper end of the support plate of the slide rail assembly. When the cover is opened, a drive mechanism and a locking mechanism work together. First, the locking mechanism lifts the support plate and cover upwards, separating them from the upper surface of the drawer body. Then, the drive mechanism moves the cover backwards to open. Conversely, when the cover is closed, the drive mechanism and locking mechanism work together. The drive mechanism moves the cover forward, and then the locking mechanism lowers the support plate and cover, sealing the cover with the upper surface of the drawer body. This ensures a good sealing effect inside the drawer, meeting the storage requirements for high-cleanliness and high-dryness items. The coordinated operation of the drive mechanism and locking mechanism effectively prevents warping and deformation of the slide rail assembly, ensuring high reliability. During drawer transportation, the cover is effectively prevented from sliding relative to the drawer body, improving transportation safety. The overall structure is ingeniously designed, simple, and reasonable, achieving automatic and intelligent operation of opening and closing the cover, providing customers with a good storage experience. The present invention provides a cabinet with a simple structural design, high feasibility in manufacturing and implementation, and strong practicality, providing a new approach to the design of cabinets with good sealing effect and storage space.

[0005] One objective of this invention is to provide a drawer with a cover, comprising a drawer body and a cover. The left and right sides of the drawer body are respectively provided with a slide rail assembly. The slide rail assembly includes a fixed rail, a movable rail, and a support plate. The fixed rail is fixed to either the left or right side of the drawer body. The left end of the cover is fixed to the upper end of the support plate located on the left side of the drawer body, and the right end of the cover is fixed to the upper end of the support plate located on the right side of the drawer body. The drawer body is further provided with a driving mechanism for driving the movable rail on the slide rail assembly to reciprocate along the front-back direction of the drawer body. A slant lifting mechanism is provided between the movable rail and the support plate. Locking mechanisms that cooperate with the slant lifting mechanism are provided on both the fixed rail and the movable rail. During the sliding opening of the movable rail relative to the fixed rail, the slant lifting mechanism and the locking mechanism work together to lift the support plate upwards, separating the cover from the upper surface of the drawer body and locking the movable rail and the support plate together. During the sliding closing of the movable rail relative to the fixed rail, the slant lifting mechanism and the locking mechanism work together to unlock the movable rail and the support plate, and lower the support plate so that the cover fits against the upper surface of the drawer body.

[0006] A drawer with a cover plate according to the present invention is configured by fixedly mounting the cover plate on the upper end of the support plate of the first slide rail assembly. When the cover plate is opened, the driving mechanism and the locking mechanism work in coordination: first, the locking mechanism drives the support plate and the cover plate to lift upward and separate from the upper end surface of the drawer main body, then the driving mechanism drives the cover plate to move backward to open. Conversely, when the cover plate is closed, the driving mechanism and the locking mechanism work in coordination: the driving mechanism drives the cover plate to move forward, then the locking mechanism drives the support plate and the cover plate to descend, so that the cover plate is in sealing fit with the upper end surface of the drawer main body, ensuring a good sealing effect inside the drawer and meeting the storage requirements for articles with high cleanliness and high dryness. Through the coordinated cooperation of the driving mechanism and the locking mechanism, the first slide rail assembly is effectively prevented from being prone to warping deformation, with high reliability. During the transportation of the drawer, the cover plate is effectively prevented from sliding relative to the drawer main body, which improves transportation safety. The overall structure is exquisitely designed, simple and reasonable, realizing automatic and intelligent operation of opening and closing the cover plate, and bringing a good storage experience to users.

[0007] A preferred technical solution is that the inclined groove lifting mechanism is a plurality of guide slot holes with a "7"-shaped structure arranged at intervals along the length direction on the movable rail, the high end of the guide slot hole faces the front side of the movable rail, on the side of the movable rail facing the corresponding fixed rail, at least a locking piece is arranged on the front side of one guide slot hole, the locking piece is made of elastic material, the front end of the locking piece is arranged on the movable rail, the rear end of the locking piece is provided with a locking hook correspondingly coinciding with the high end of the corresponding guide slot hole, the middle part of the locking piece is provided with a boss facing the corresponding fixed rail, the upper end surface of the boss is an arc-shaped convex surface structure, the fixed rail is provided with an unlocking pin correspondingly adapted to the boss, a plurality of locking pins which are movably and correspondingly inserted through the low ends of the guide slot holes on the corresponding movable rail one by one are fixed at intervals along the length direction on the support plate; during the process that the movable rail slides to open or slide to close relative to the fixed rail, the unlocking pin is used to trigger the boss to drive the locking hook on the locking piece to move downward to avoid the locking pin sliding and running along the guide slot hole, and the locking piece, the unlocking pin and the locking pin constitute the locking mechanism. The locking mechanism has a simple structural design and good adaptation and coordination with the first slide rail assembly, so that the cover plate can be lifted or lowered in a coordinated manner when the movable rail slides relative to the fixed rail, ensuring the smoothness when the driving mechanism drives the cover plate to open and close.

[0008] A further preferred technical solution includes a groove along its length on the side of the movable rail facing the corresponding fixed rail. The locking piece is located inside the groove on the movable rail, and the lower end of the locking piece has a support arm extending obliquely downwards and backwards from the movable rail. The lower end of the support arm abuts against the bottom surface of the corresponding groove. The locking piece being installed inside the groove of the movable rail effectively prevents interference with the sliding operation of the movable rail. The support arm at the lower end of the locking piece abuts against the bottom surface of the groove, significantly improving the rebound performance of the locking piece, thereby ensuring the agile response of the locking mechanism to the lifting or lowering of the cover plate, i.e., ensuring the smoothness of opening or closing the cover plate.

[0009] A further preferred technical solution includes a countersunk hole at the front end of the locking piece, which is riveted and fixed to the groove on the corresponding movable rail by a rivet passing through the countersunk hole; a limiting plate is fixed to the front end of the fixed rail, and the front ends of the movable rail and the support plate both abut against the limiting plate. The fixing and installation of the locking piece on the movable rail is simple, and the rivet is hidden inside the countersunk hole, avoiding obstruction to the sliding movement of the movable rail; the limiting plate limits the movement of the movable rail and the support plate, ensuring the accurate positioning of the cover when closed.

[0010] A preferred technical solution further includes a drive mechanism comprising a motor, a gearbox, and a lead screw. The motor is fixed to the outer wall of the rear panel of the drawer body. The lead screw is located below the slide rail assembly. A nut is screwed to the front end of the lead screw, and a connecting piece is fixed to the nut for fixed connection with the front end of the corresponding movable rail. The input end of the gearbox is connected to the output shaft of the motor via a drive shaft, and the output end of the gearbox is connected to the rear end of the lead screw. The drive mechanism has an ingenious structural design and a reasonable layout, ensuring the smooth fabrication and implementation of the drawer of this invention. Furthermore, the drive mechanism is located entirely outside the drawer, causing no interference with the internal space of the drawer and ensuring a large internal storage capacity.

[0011] A preferred technical solution also includes a "7"-shaped support plate fixedly mounted on the upper end of the bracket plate, with the left and right ends of the cover plate fixedly installed on the corresponding "7"-shaped support plates. The horizontal plate of the "7"-shaped support plate contacts the lower end face of the cover plate, appropriately increasing the contact area between the upper end of the bracket plate and the lower end face of the cover plate, improving the installation stability of the cover plate on the slide rail assembly, and also improving the convenience of fixing and installing the cover plate on the slide rail assembly.

[0012] A further preferred technical solution includes a sealing ring on the outer periphery of the upper surface of the drawer body and / or the lower surface of the cover, for sealing and filling the gap between the outer periphery of the upper surface of the drawer body and the lower surface of the cover. The sealing ring further improves the sealing performance between the cover and the upper surface of the drawer body, thus ensuring a better sealing effect inside the drawer.

[0013] The second objective of this invention is to provide a cabinet, comprising a cabinet body, wherein the cabinet body has the aforementioned drawer with a cover installed inside.

[0014] The present invention provides a cabinet with a simple structural design, high feasibility in manufacturing and implementation, and strong practicality, providing a new approach to the design of cabinets with good sealing effect and storage space.

[0015] Preferably, the drawer body's front panel has a slot on its outer wall; it also includes a cabinet door panel, the side of which facing the cabinet body has a buckle with a insert block. The cabinet door panel is inserted into the slot on the front panel of the drawer body via the insert block on the buckle, and the cabinet door panel and the front panel of the drawer body are further fixedly connected by screws. This simple connection method between the cabinet door panel and the front panel of the drawer body allows the drawer with a cover to match existing cabinets well, ensuring the overall aesthetic appeal of the cabinetry.

[0016] More preferably, the slot extends obliquely upwards towards the front side of the drawer body, and the opening of the slot is a countersunk groove structure; the insert on the buckle extends obliquely downwards towards the rear side of the cabinet door panel. During the assembly of the cabinet door panel and the drawer body, the cabinet door panel can be pre-positioned and suspended inside the slot on the front side panel of the drawer body using the insert on the buckle, and then the cabinet door panel and the front side panel of the drawer body are fixed together with screws, improving the convenience, precision, and efficiency of cabinet door panel installation.

[0017] The advantages and beneficial effects of this invention are as follows:

[0018] 1. This invention provides a drawer with a cover plate. The cover plate is fixedly installed on the upper end of the support plate of the slide rail assembly. When the cover plate is opened, a drive mechanism and a locking mechanism work together. First, the locking mechanism lifts the support plate and cover plate upwards, separating them from the upper surface of the drawer body. Then, the drive mechanism moves the cover plate backwards to open. Conversely, when the cover plate is closed, the drive mechanism and locking mechanism work together. The drive mechanism moves the cover plate forward, and then the locking mechanism lowers the support plate and cover plate, ensuring a tight seal between the cover plate and the upper surface of the drawer body. This ensures a good sealing effect inside the drawer, meeting the storage requirements for items requiring high cleanliness and dryness. The coordinated operation of the drive mechanism and locking mechanism effectively prevents warping and deformation of the slide rail assembly, ensuring high reliability. During drawer transportation, the cover plate is effectively prevented from sliding relative to the drawer body, improving transportation safety. The overall structure is ingeniously designed, simple, and reasonable, achieving automatic and intelligent operation of opening and closing the cover plate, providing customers with a superior storage experience.

[0019] 2. The locking mechanism has a simple structural design and good compatibility with the slide rail assembly. As the moving rail slides relative to the fixed rail, it can work together to lift or lower the cover plate, ensuring the smoothness of the drive mechanism when opening and closing the cover plate.

[0020] 3. The locking plate is installed inside the groove of the moving rail, which effectively avoids the locking plate interfering with the sliding operation of the moving rail; the support arm at the lower end of the locking plate abuts against the bottom surface of the groove, which significantly improves the rebound performance of the locking plate, thereby ensuring the responsiveness of the locking mechanism when the cover is raised or lowered, that is, ensuring the smoothness of the cover opening or closing.

[0021] 4. The locking plate is easy to install on the movable rail, and the rivets are hidden inside the countersunk holes to avoid obstructing the sliding operation of the movable rail; the limiting plate limits the movable rail and the bracket plate, ensuring the accuracy of the cover plate when it is closed.

[0022] 5. The ingenious structural design and reasonable layout of the drive mechanism ensure that the drawer of this invention can be successfully manufactured and implemented. Furthermore, the drive mechanism is located outside the drawer and does not interfere with the internal space of the drawer, thus ensuring that the drawer has a large capacity.

[0023] 6. The horizontal plate of the “7”-shaped support plate contacts the lower end face of the cover plate, which appropriately increases the contact area between the upper end of the support plate and the lower end face of the cover plate, improves the installation stability of the cover plate on the slide rail assembly, and improves the convenience of fixing and installing the cover plate on the slide rail assembly.

[0024] 7. The cabinet of the present invention has a simple structural design, is highly feasible to manufacture and implement, and is highly practical, providing a new idea for the design of cabinets with good sealing effect and storage space.

[0025] 8. The simple fixing method between the cabinet door panel and the front panel of the drawer body allows the drawer with the cover to match the existing cabinet well, ensuring the overall aesthetic effect of the cabinet.

[0026] 9. The slot extends obliquely upwards towards the front side of the drawer body, and the opening of the slot is a countersunk groove structure. The insert on the buckle extends obliquely downwards towards the rear side of the cabinet door panel. During the assembly of the cabinet door panel and the drawer body, the cabinet door panel can be pre-positioned and suspended in the slot on the front side panel of the drawer body by inserting it through the insert on the buckle. Then, the cabinet door panel and the front side panel of the drawer body are fixedly connected by screws, which improves the convenience, precision, and efficiency of the cabinet door panel installation.

[0046] like Figures 1-12As shown in the figure, the present invention is a drawer with a cover plate, comprising a drawer main body 1 and a cover plate 2, wherein a first slide rail assembly 3 is correspondingly arranged on each of the left side plate and the right side plate of the drawer main body 1, the first slide rail assembly 3 comprises a fixed rail 3-1, a movable rail 3-2 and a support plate 3-3, the fixed rail 3-1 is fixedly arranged on the left side plate or the right side plate of the drawer main body 1, the left end of the cover plate 2 is fixedly arranged at the upper end of the support plate 3-3 located on the left side of the drawer main body 1, the right end of the cover plate 2 is fixedly arranged at the upper end of the support plate 3-3 located on the right side of the drawer main body 1, the drawer main body 1 is further provided with a driving mechanism 4 for driving the movable rail 3-2 on the first slide rail assembly 3 to slide reciprocatingly along the front-rear direction of the drawer main body 1, an inclined slot lifting mechanism is arranged between the movable rail 3-2 and the support plate 3-3, and a locking mechanism 5 matched with the inclined slot lifting mechanism is arranged on the fixed rail 3-1 and the movable rail 3-2;

[0047] During the process that the movable rail 3-2 slides and opens relative to the fixed rail 3-1, the inclined slot lifting mechanism and the locking mechanism 5 cooperate synergistically to drive the support plate 3-3 to lift upward, so that the cover plate 2 is separated from the upper end face of the drawer main body 1, and the movable rail 3-2 and the support plate 3-3 are locked with each other;

[0048] During the process that the movable rail 3-2 slides and closes relative to the fixed rail 3-1, the inclined slot lifting mechanism and the locking mechanism 5 cooperate synergistically to unlock the movable rail 3-2 and the support plate 3-3 from each other, and drive the support plate 3-3 to descend, so that the cover plate 2 is attached to the upper end face of the drawer main body 1. A control panel electrically connected with the driving mechanism 4 is arranged on the drawer main body 1 or the cover plate 2.

[0049] Preferably, the inclined slot lifting mechanism is a plurality of "7"-shaped guide slot holes 3-2-1 arranged at intervals along the length direction on the movable rail 3-2, the high end of the guide slot hole 3-2-1 faces the front side of the movable rail 3-2, on the side of the movable rail 3-2 facing the corresponding fixed rail 3-1, at least a locking piece 5-1 is arranged at the front side of one guide slot hole 3-2-1, the locking piece 5-1 is made of elastic material, the front end of the locking piece 5-1 is arranged on the movable rail 3-2, the rear end of the locking piece 5-1 is provided with a locking hook 5-1-2 correspondingly coinciding with the high end of the corresponding guide slot hole 3-2-1, the middle part of the locking piece 5-1 is provided with a boss 5-1-3 facing the corresponding fixed rail 3-1, the upper end face of the boss 5-1-3 is of an arc-shaped convex surface structure, the fixed rail 3-1 is provided with an unlocking pin 5-3 correspondingly adapted to the boss 5-1-3, and a plurality of locking pins 5-2 which are correspondingly and movably inserted through the low ends of the guide slot holes 3-2-1 on the corresponding movable rail 3-2 one by one are fixedly arranged on the support plate 3-3 at intervals along the length direction;

[0050] During the process of sliding open or close of the movable rail 3-2 relative to the fixed rail 3-1, the unlocking pin 5-3 is used to trigger the boss 5-1-3 to drive the locking hook 5-1-2 on the locking piece 5-1 to move downward to avoid the locking pin 5-2 sliding along the guide slot 3-2-1. The locking piece 5-1, the unlocking pin 5-3, and the locking pin 5-2 constitute the locking mechanism 5.

[0051] More preferably, the movable rail 3-2 has a groove along its length on one side facing the corresponding fixed rail 3-1, the locking piece 5-1 is located inside the groove on the movable rail 3-2, and the lower end of the locking piece 5-1 has a support arm 5-1-4 that extends obliquely downward toward the rear side of the movable rail 3-2, the lower end of the support arm 5-1-4 abutting against the bottom surface of the corresponding groove.

[0052] In a further preferred embodiment, the locking piece 5-1 has a countersunk hole 5-1-1 at its front end, and the front end of the locking piece 5-1 is riveted and fixed to the groove on the corresponding movable rail 3-2 by a rivet 5-4 passing through the countersunk hole 5-1-1; the fixed rail 3-1 has a limiting plate 3-1-1 fixedly provided at its front end, and the front ends of the movable rail 3-2 and the support plate 3-3 both abut against the limiting plate 3-1-1.

[0053] Preferably, the drive mechanism 4 includes a motor 4-1, a gearbox 4-3, and a lead screw 4-4. The motor 4-1 is fixed to the outer wall of the rear side panel of the drawer body 1. The lead screw 4-4 is located below the slide rail assembly 3. A nut 4-5 is screwed to the front end of the lead screw 4-4. A connecting piece 4-5-1 for fixed connection with the front end of the corresponding movable rail 3-2 is fixed on the nut 4-5.

[0054] Preferably, a “7”-shaped support plate 3-3-1 is fixedly provided on the upper end of the bracket plate 3-3, and the left and right ends of the cover plate 2 are fixedly installed on the corresponding “7”-shaped support plate 3-3-1.

[0055] Furthermore, preferably, the outer periphery of the upper end face of the drawer body 1 and / or the lower end face of the cover plate 2 is provided with a sealing ring for sealing and filling the gap between the outer periphery of the upper end face of the drawer body 1 and the lower end face of the cover plate 2.

[0056] The working principle of a drawer with a cover in Example 1:

[0057] (I) Cover opening principle: In the initial state, the locking pin 5-2 is located at the lower end of the guide slot 3-2-1, and the unlocking pin 5-3 is located behind the boss 5-1-3 and is in a disengaged state (see Appendix). Figures 7-8 When the start button on the control panel is pressed, the output shaft of motor 4-1 drives the transmission shaft 4-2 to rotate, which in turn drives the lead screw 4-4 to rotate via gearbox 4-3. Simultaneously, nut 4-5 drives movable rail 3-2 to move backward via connecting piece 4-5-1. Locking pin 5-2 gradually moves from the lower end of guide slot 3-2-1 to the higher end of guide slot 3-2-1. At this time, unlocking pin 5-3 triggers the rear end of boss 5-1-3 and drives locking hook 5-1-2 to move downward to avoid locking pin 5-2 (see appendix). Figures 9-10 Simultaneously, the cover plate 2 gradually moves upward along with the support plate 3-3 and gradually separates from the upper surface of the drawer body 1. As the movable rail 3-2 continues to move backward, the locking pin 5-2 moves to the high end of the guide slot 3-2-1, and the unlocking pin 5-3 moves to the front end of the boss 5-1-3 and disengages from the boss 5-1-3. Then, the locking hook 5-1-2 springs back and hooks onto the locking pin 5-2 located at the high end of the guide slot 3-2-1 to lock it in place (see Appendix). Figures 11-12 As the movable rail 3-2 continues to move backward, the cover plate 2, the movable rail 3-2, and the support plate 3-3 continue to move backward until the movable rail 3-2 and the fixed rail 3-1 are fully opened, and the cover plate 2 is fully opened.

[0058] (II) Cover plate closing principle:

[0059] When the close button on the control panel is activated, the output shaft of motor 4-1 drives the transmission shaft 4-2 to rotate, which in turn drives the lead screw 4-4 to rotate via gearbox 4-3. Simultaneously, nut 4-5 drives the movable rail 3-2 and cover plate 2 forward via connecting piece 4-5-1 until the unlocking pin 5-3 triggers the front end of boss 5-1-3 and drives the locking hook 5-1-2 to move downward and unlock and disengage from locking pin 5-2. As the movable rail 3-2 continues to move forward, locking pin 5-2 gradually moves from the high end of guide slot 3-2-1 to the low end of guide slot 3-2-1. At the same time, cover plate 2 gradually moves downward with bracket plate 3-3 until the movable rail 3-2 and bracket plate 3-3 reach the front end of fixed rail 3-1. At this point, the front end of movable rail 3-2 and the front end of bracket plate 3-3 abut against limit plate 3-1-1, and cover plate 2 is fully closed and fits against the upper surface of drawer body 1.

[0060] Example 2

[0061] like Figures 13-16As shown, the present invention is a cabinet, including a cabinet body 6, inside which a drawer with a cover as described in Embodiment 1 is installed. The drawer with the cover is installed inside the cabinet body 6 via a slide rail assembly 2 9. The fixed rail of the slide rail assembly 2 9 is fixedly installed on the side panel of the cabinet body 6, and the drawer with the cover is fixedly installed on the movable rail of the slide rail assembly 2 9.

[0062] Preferably, the drawer body 1 has a slot 1-1-1 on the outer wall of the front side panel 1-1; it also includes a cabinet door panel 7, the cabinet door panel 7 has a buckle 8 on the side facing the cabinet body 6, the buckle 8 has a plug 8-1, the cabinet door panel 7 is inserted into the slot 1-1-1 on the front side panel 1-1 of the drawer body 1 through the plug 8-1 on the buckle 8, and the cabinet door panel 7 and the front side panel 1-1 of the drawer body 1 are also fixedly connected by screws.

[0063] More preferably, the slot 1-1-1 extends obliquely upward toward the front side of the drawer body 1, and the opening of the slot 1-1-1 is provided as a countersunk groove structure, and the insert 8-1 on the buckle 8 extends obliquely downward toward the rear side of the cabinet door panel 7.

[0064] The present invention provides a cabinet with a simple structural design, high feasibility in manufacturing and implementation, and strong practicality, providing a new approach to the design of cabinets with good sealing effect and storage space.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
