[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0048] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] See also Figures 1 to 12The present application provides a rice box, comprising a box body 100, a box cover 200 and a cover plate 300. The box body 100 is used to store food, such as rice, mung beans, etc. The interior of the box body 100 is a storage space 110 and the top is open. The box cover 200 is arranged on the box body 100, specifically connected to the top of the box body 100, and the box cover 200 has a take-in and take-out opening 210 connected to the storage space 110. The cover plate 300 is movably mounted on the box cover 200, and has a closed state of enclosing the take-in and take-out opening 210, and an open state of exposing the take-in and take-out opening 210.

[0050] For the convenience of description and understanding, the rice box has Figure 1 The length, width and height directions are shown as X, Y and Z, wherein the length direction may also be referred to as the front-to-back direction.

[0051] In this embodiment, the rice box further includes a guide arm 400, a first elastic member 500 and a locking mechanism. The cover plate 300 is provided with a guide groove 310, the guide arm 400 is hinged to the box cover 200 and has a first free end away from the hinged part of the box cover, and the first free end cooperates with the guide groove 310 to limit the movement path of the cover plate 300. The first elastic member 500 acts between the box cover 200 and the cover plate 300, and the first elastic member 500 accumulates force when the cover plate 300 is in a closed state, and is used to drive the cover plate 300 to an open state. The locking mechanism acts between the box cover 200 and the cover plate 300 to keep the cover plate 300 in a closed state.

[0052] The cooperation between the first free end and the guide groove 310 is understood as that during the opening process of the cover plate, there is:

[0053] In the first matching state, the cover plate 300 moves synchronously with the rotation of the guide arm 400, such as the flipping relative to the box cover 200 described below;

[0054] In the second matching state, the cover plate 300 slides relative to the box cover 200 .

[0055] The following takes one of the movement paths as an example. During the opening operation, the locking mechanism is unlocked, and the cover 300 moves under the action of the first elastic member 500. In the initial stage of movement, it is restricted by the guide arm 400, that is, the first free end and the guide groove 310 are in the first matching state. Therefore, the cover 300 drives the guide arm 400 to rotate relative to the box cover 200. The cover 300 moves synchronously with the guide arm 400 until the first free end and the guide groove 310 switch to the second matching state, and the cover 300 begins to slide relative to the box cover 200 and switches to the open state.

[0056] The rice box of the present application uses the first elastic member as a power source, and with the help of the cooperation between the cover plate and the guide arm, the cover plate has at least two movement modes. On the one hand, it is different from the prior art and is a new structure; on the other hand, compared with the prior art, the cover plate can be closer to the box lid in the open state, so that the height of the rice box is lower when in use, and can be placed in a space with a lower height.

[0057] The first elastic member 500 is a tension spring, which is in a stretched state to store force when the cover 300 is in a closed state. Preferably, the tension spring is in a natural state or still in a stored force state when the cover 300 is in an open state to ensure that the cover 300 is fully opened.

[0058] In the figure, the cover plate 300 is located at the front side of the box cover 200 in the closed state, and is located at the rear side of the box cover 200 in the open state. One end of the tension spring is hooked on the front side of the cover plate 300, and the other end is connected to the guide arm 400. The guide arm 400 is provided with a force applying seat 410 for connecting the tension spring, and the force applying seat 410 and the first free end are arranged on different sides of the flip axis of the guide arm 400.

[0059] Key References Figures 9 to 12 When opening, the locking mechanism is in the unlocked state, the tension spring contracts to drive the guide arm 400 to flip, and under the guidance of the guide arm 400, the cover plate 300 and the first free end are in the first matching state, the rear end of the cover plate 300 flips and moves toward the rear side of the rice box as a whole, and when the cover plate 300 and the first free end are in the second matching state, the cover plate 300 slides to the rear side of the rice box relative to the box cover 200 until it switches to the open state. The above movement path of the cover plate can make the cover plate infinitely close to the upper surface of the box cover 200 in the open state, which depends on the length of the guide arm 400, the tilting angle of the cover plate 300, the extension path of the guide groove 310, etc.

[0060] In one embodiment, the guide groove 310 includes a first section and a second section, and the first free end of the guide arm 400 has a guide head 420 that cooperates with the guide groove 310. When the cover is in a closed state, the guide head 420 is in the second section. When the cover 300 is flipped up, the guide head 420 is adapted to the second section and is in a first cooperative state. When the cover 300 slides, the guide head 420 is adapted to the first section and is in a second cooperative state. Figure 7In the embodiment, the first section is a straight groove 311, and the second section is a circular groove 312. The diameter of the circular groove 312 is greater than the width of the straight groove 311, and the guide head 420 is a waist-shaped structure. When the cover plate 300 is tilted, the waist-shaped structure cooperates with the circular groove 312, but cannot enter the straight groove 311, thereby limiting the sliding of the cover plate 300 and only allowing it to tilt. During the rotation process of the guide arm 400, until the two planes 421 of the waist-shaped structure are adapted to the straight groove 311, the guide head 420 enters the straight groove 311 under the drive of the tension spring, and can slide in the straight groove 311 to guide the sliding of the cover plate 300.

[0061] Among them Figures 4 to 6 As shown, a first limit seat 220 is fixed on the box cover 200, and the first limit seat 220 acts on the guide arm 400 to limit its flipping range. Specifically, the guide arm 400 will be against and limited by the first limit seat 220 during the flipping process and cannot be further flipped. At the same time, the guide head 420 and the guide groove 310 are in the second matching state, and then the cover plate 300 is driven to slide under the traction of the tension spring.

[0062] In one embodiment, the cover plate 300 is provided with two ribs 320 arranged side by side on the side facing the box body 100, and the guide groove 310 is provided on each rib 320. Specifically, the two ribs 320 are arranged on both sides of the box body in the width direction, and the corresponding guide arms 400 are two independently configured, or one extending in the width direction and adopting an integrated structure. Among them, in the integrated structure, the guide arm 400 is a plate-like structure as a whole, and the plate-like structure is arranged across the access opening 210 along the length direction of the guide arm itself, and the guide head 420 and the force application seat 410 are respectively provided on both sides along the width direction of the guide arm itself.

[0063] In one embodiment, if Fig.13 As shown, a second limit seat 230 is fixed on the box cover 200. When the cover plate 300 is in the closed state, the second limit seat 230 acts on the guide arm 400 to limit the turning of the guide arm 400. When the cover plate 300 is in the closed state, the force generated by the locking mechanism is located at the front end of the cover plate 300, and the second limit seat 230 is located at the rear end of the access opening 210, generating a force on the rear end of the cover plate 300. Both the front and rear ends generate a force on the cover plate 300 to keep the cover plate 300 able to effectively close the access opening 210 to avoid partial warping.

[0064] At least one of the second limit seat 230 and the guide arm 400 is an elastic deformation structure at the matching part, including but not limited to the fact that both are made of plastic material and the local deformation ability of the plastic material itself. When the locking mechanism is in the unlocked state, the force generated by the tension spring drives the guide arm 400 to squeeze the second limit seat 230 to flip.

[0065] In one embodiment, if Fig.14As shown, the locking mechanism includes:

[0066] A fixed lock 240 is disposed on one of the box cover 200 and the cover plate 300;

[0067] The movable lock 330 is disposed on the other of the box cover 200 and the cover plate 300. The movable lock 330 cooperates with the fixed lock 240 to keep the cover plate 300 in a closed state;

[0068] The second elastic member 340 acts on the movable locking member 330 to keep the movable locking member 330 in cooperation with the fixed locking member 240 .

[0069] In the figure, the fixed lock member 240 is arranged on the box cover 200 , the movable lock member 330 is arranged on the cover plate 300 , and the cover plate 300 is further provided with an unlocking member 350 which is linked with the movable lock member 330 .

[0070] The rice box of the present application uses the first elastic member as a power source, and with the help of the cooperation between the cover plate and the guide arm, the cover plate has at least two movement modes. On the one hand, it is different from the prior art and is a new structure; on the other hand, compared with the prior art, the cover plate can be closer to the box lid in the open state, so that the height of the rice box is lower when in use, and can be placed in a space with a lower height.

[0071] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0072] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
