Detailed ways

Implementation Mode 1

The inventor of the present application found that the food pick-and-place box used in the prior art needs to manually open and close the box cover during the process of picking and placing the food, which is relatively cumbersome.

In view of this, in the first embodiment of the present application, a food pick-and-place box is provided, as shown in Fig. 1 and Fig. 2, including:

Shell 1 and box cover 3;

The supporting platform 2 is arranged in the casing 1, and is used for placing the food tray 4;

The opening and closing device 5 is arranged in the housing and is connected to the box cover 3 in transmission. The opening and closing device 5 is used to drive the box cover 3 to close when the food tray 4 is placed on the support platform 2; and when the food tray 4 leaves the support platform 2 o'clock, drive lid 3 to open.

Wherein, the casing 1 can usually be made of plastic material, and is used to form the overall frame of the object pick-and-place box of the present application. In order to enable the user to see the food in the box cover 3 more intuitively, preferably, the box cover 3 may be transparent. Support platform 2 can be a platform usually as the position of propping up food tray 4, can be provided with the rough surface that is used for anti-slip on support platform 2, and, can also be provided with for limiting the position of food tray 4 on support platform 2 limit department.

Wherein, the limiting portion can be formed as a downwardly recessed groove on the support platform 2 , and this groove can be matched with the protrusion at the bottom of the food tray 4 to achieve the purpose of limiting. As a further preference of the present application, as shown in FIG. 3 , the limiting portion can also be a single-sided blocking wall 21 formed by protruding upward from the surface edge of the support table 2.

In the present application, the opening and closing device 5 can be configured in various structures, as long as the opening and closing of the box cover 3 can be realized.

Moreover, when the food tray 4 is placed on the support platform 2, the opening and closing device 5 can be triggered in various ways.

For example, the opening and closing device 5 can be electrically controlled to realize the electric opening and closing of the lid 3 . At this time, the opening and closing device 5 may include a motor and transmission components. These transmission components may include various mechanical combinations such as gears, connecting rods, racks, etc., which can realize the above-mentioned functions only by virtue of existing technologies. In addition, the opening and closing part can also monitor whether the food tray 4 is placed on the support platform 2 through sensors. This sensor can be an optical sensor or a weight sensor. Specifically, when the sensor detects that the food tray 4 is placed on the support platform 2, the motor drives the transmission part to drive the lid 3 to close; and when the sensor detects that the food tray 4 is picked up from the support platform 2, the motor Drive transmission parts, drive lid 3 to open.

However, for the convenience of taking or putting down the food tray 4, as a further preference of the present application, as shown in FIG. Tray 4. Accordingly, the user can put his hand into the space covered by the box cover 3 through the pick-and-place opening 31, and then pick up the food tray 4, which is very convenient. Of course, when the pick-and-place opening 31 is not provided, the detection of the user's pick-and-place action can also be realized by using the sensor arranged outside the casing 1 of the food pick-and-place box.

In addition, as a further preference, an outwardly protruding grip handle can also be extended on the food tray 4, so that the size of the height direction of the pick-and-place opening 31 only needs to be adapted to the grip handle, so the pick-and-place The mouth 31 will occupy a smaller area, thereby further improving the freshness preservation effect of food.

In the prior art, it is necessary to manually open and close the lid during the process of taking and placing food. For the customers of the store, it takes a certain amount of time to manually open/turn over the lid 3 . When the switch setting of the box cover is relatively hidden, they also need to pay additional learning costs. In the application scenario of revolving sushi, it may even be too late to get the required food because the lid of the box is not opened in time. And the customer also easily damages the food pick-and-place box because of unskilled operation.

However, for the chefs in the store, when they need to add new food to the empty food pick-and-place box, they need to click triggers such as "trigger" and "switch" after putting the food tray in order to correct it. Close the lid firmly. This will take more time in repeated operations, and repeated repeated operations may lead to mistakes, or even forget to close the lid, which will affect the user experience.

Therefore, compared with the prior art, the food pick-and-place box of the present application has significantly improved convenience and user experience.

Implementation Mode Two

The inventors of the present application found that when the lid is opened and closed by electrical control, since the mechanical transmission consumes relatively more power, it poses a challenge to the battery life of the food pick-and-place box.

In view of this, the second embodiment of the present application provides a food pick-and-place box. The second embodiment is a further improvement of the first embodiment. The main improvement is that, in the second embodiment of the present application, The opening and closing of the box cover 3 is realized by means of purely mechanical transmission.

Specifically, in this embodiment, as shown in FIG. 4 , the supporting platform 2 can reciprocate along the height direction, that is, the arrow direction in FIG. 4 .

That is to say, under the pressure of the food tray 4, the support platform 2 will move downward along the height direction.

At this point, the opening and closing device 5 includes:

The elastic member 51 is in transmission connection with the support platform 2 and is used to make the support platform 2 tend to move upward along the height direction. The elastic force of the elastic member 51 is smaller than the pressure generated when the food tray 4 is placed on the support platform 2 .

That is to say, under the reaction force of the elastic member 51 , when there is no pressure from the food tray 4 , the supporting table 2 will move upward along the height direction.

During the movement of the support platform 2, a movement stroke will be generated. Accordingly, the opening and closing device 5 also includes:

The transmission transfer assembly 52 is connected with the support platform 2 and the box cover 3 respectively, and is used to convert the downward movement of the support platform 2 into the closing movement of the box cover 3, and is used to convert the upward movement of the support platform 2 For the opening motion of lid 3.

The cooperation between the elastic component 51 and the transmission transfer assembly 52 of the present application can have various forms. For example, as shown in Figure 4, the support platform 2 can be jacked up by means of an elastic member 51 arranged at the bottom of the support platform 2, that is, a spring; , convert the up and down movement of the support table 2 into the overturning movement of the box cover 3 .

After fully utilizing the movement stroke of the support platform 2, the up and down movement of the support platform 2 is converted into the opening and closing movement of the lid 3, so that the automatic opening and closing of the lid 3 can be realized without power intervention. Compared with the technical solution using sensors, motors and transmission components, the technical solution of this embodiment is simple in structure, low in cost, can work without power supply, has strong adaptability, good battery life, and has better practical advantages.

Implementation Mode Three

In order to further improve the stability of the movement and reduce the space occupied by components, the third embodiment of the present application provides a food pick-and-place box. The third embodiment is a further improvement of the second embodiment, and its main improvement is that, in the third embodiment of the present application, further improvements are made to the structure of the opening and closing device 5 .

Specifically, referring to Fig. 5 and Fig. 6, in this embodiment, the transmission transfer assembly 52 includes:

The first activity section 52a, the first activity section 52a has:

The first connecting portion 52a1 is pivotally connected to the support platform 2;

The first supporting part 52a2 is rotatably connected with the housing 1;

The second connecting part 52a3 is connected with the box cover 3;

The supporting platform 2 drives the first connecting part 52a1 to move in the same direction, the first supporting part 52a2 rotates and drives the second connecting part 52a3 to turn over relative to the first connecting part 52a1, thereby driving the box cover 3 to close or open.

Wherein, optionally, the transmission transfer assembly 52 may also include:

The second movable section 52c is arranged opposite to the first movable section 52a, and is used to assist the movement of the first movable section 52a. In order to assist the movement of the first movable section 52a, the second movable section 52c can also have:

The third connecting part 52c1 is pivotally connected with the supporting platform 2;

The second supporting portion 52c2 is rotatably connected with the casing 1 .

The second movable section 52c can be arranged on the opposite side of the first movable section 52a, so that the force of the supporting platform 2 is more balanced. The only difference from the first movable section 52a is that the second movable section 52c does not need to be connected with the box cover 3 .

The provided second movable section 52c makes the transmission movement between the supporting platform and the movable section more smooth, which can prolong the service life.

In this embodiment, the elastic member 51 may be similar to the second embodiment, and is configured to lift up a spring that supports the movement of the platform. However, in order to further promote the movement of the first movable joint 52a and improve fluency, optionally, as shown in FIG. Inside, and can reciprocate along the first track groove 11.

Meanwhile, the transmission transfer assembly 52 also includes:

The first pull rod 52b is pivotally connected to the first support portion 52a2, and can reciprocate along the length direction of the first track groove 11;

The elastic member 51 is connected to the first pull rod 52b, so that the first pull rod 52b tends to move toward the support platform 2, and the first movable joint 52a tends to lift the support platform 2 through the first connecting portion 52a1.

At this time, the elastic member 51 may be a tension spring, and by means of tension, drives the first support portion 52a2 to move toward the direction of approaching the support platform 2 , and then drives the first connecting portion 52a1 to tend to lift the support platform 2 .

When the second movable joint 52c is provided, similarly, the transmission transfer assembly 52 may also include: a second pull rod 52d, which is pivotally connected to the second support part 52c2, and can be arranged along the second track groove 12 on the housing 1. Reciprocating motion in the length direction.

At the same time, the elastic member 51 is respectively connected with the first pull rod 52b and the second pull rod 52d, so that both the first pull rod 52b and the second pull rod 52d tend to move in a direction close to the support platform 2, and the first movable joint 52a tends to pass through The first connecting portion 52a1 lifts up the supporting platform 2 , while the second movable joint 52c tends to lift up the supporting platform 2 through the second connecting portion 52a3 . At this time, the elastic member 51 may be a tension spring.

In this way, the force of the two can be more balanced, so the service life of the food pick-and-place box can be better extended.

It is particularly worth mentioning that, even if no track groove is provided, the purpose of the present application can also be achieved through some other deformation structures when only each supporting portion is pivotally connected to the housing 1 . For example, the first connecting part 52a1 can be telescopically arranged on the first movable joint 52a, and when the elastic member 51 moves the supporting platform 2 upward, the first connecting part 52a1 is elongated to match the rising of the supporting platform 2 . When the supporting platform 2 moves downward, the first connecting portion 52a1 shortens to match the lowering of the supporting platform 2 .

There are many other deformable structures, which are not repeated in this application due to space limitations.

In addition, optionally, the angle formed by the plane shared by the first connecting portion 52a1 and the first supporting portion 52a2 and the plane shared by the second connecting portion 52a3 and the first supporting portion 52a2 is greater than or equal to 90 degrees.

Setting the angle between the two to a state greater than or equal to 90 degrees can make the opening of the lid 3 larger, making it easier to take out the food tray 4, and avoiding the positional interference between the lid 3 and the food tray 4, resulting in the use of The problem of food placement space. Accordingly, the projection of the first movable section 52a on the side can be formed in a shape similar to the character "7", so as to save the space it occupies.

In the implementation of the present application, a process step of opening and closing the food pick-and-place box based on the above-mentioned structure is given, and a simple example is as follows:

1. Referring to Fig. 5, the food tray 4 is placed in the food pick-and-place box. The pressing of the food tray 4 to the supporting platform 2 makes the supporting platform 2 descend to the lowest position of the stroke. At this time, the first connecting portion 52a1 of the first movable section 52a is pressed down to a lower point, causing the first supporting portion 52a2 to be pushed farther away from the support platform 2 along the first track groove 11, while the second connecting portion Part 52a3 is affected by the transmission, drives and makes the box cover 3 in the closed state. Since the first support part 52a2 is far away from the support platform 2 and at the same time the first pull rod 52b is connected to the first support part 52a2, the first pull rod 52b is also pulled to a position far from the support platform 2 . The same is true for the second pull rod 52d, so after the first pull rod 52b and the second pull rod 52d pull the elastic component 51 apart, the elastic component 51 will store elastic potential energy.

2. As shown in FIG. 6 , when the food tray 4 is gently lifted upward from the pick-and-place opening 31 , the supporting table 2 no longer receives pressure. The elastic potential energy of the elastic member 51 is released, so that the first pull rod 52b and the second pull rod 52d move toward each other, and synchronously drive the first support portion 52a2 and the second support portion 52c2 along the first track groove 11 and the second track groove respectively. 12 opposite movement. The movement of the two props up the first connecting portion 52a1 on the first movable section 52a and the third connecting portion 52c1 on the second movable section 52c upwards synchronously, so that the supporting platform 2 is jacked up, and at the same time, due to the first movable The second connecting portion 52a3 on the section 52a is driven to tilt, causing the box cover 3 to be driven to open. After the lid 3 is opened, the food tray 4 can be taken out.

3. Referring to Fig. 5 again, when the box cover 3 needs to be closed, only the food tray 4 needs to be put in again. Under the pressure of the food tray 4, the supporting platform 2 will descend and drive the lid 3 to close again.

It can be seen that the embodiment of the present application can take out and place the food tray 4 very naturally, which has the advantages of convenience and quickness.

In addition, optionally, as shown in FIG. 7, the opening and closing device 5 further includes:

The guide part 6 is in contact with the support platform 2 and is used to guide the movement direction of the support platform 2 . The guide member 6 may generally be formed as various rails or position-limiting members. Specifically for this embodiment, the guide member 6 may include a convex rib 61 formed on the support platform 2 and a concave strip 62 formed on the inner wall of the housing 1 . When the support platform 2 moves up and down, the convex rib 61 slides up and down in the concave strip 62, which can make the movement of the support platform 2 smoother and prevent the support platform 2 from deviating from the expected movement track.

When the countdown of the timer reaches the preset time, a warning message will be displayed on the display to remind the staff to pay attention. In particular, the warning message can also be divided into multiple levels of prompt messages. For example, when it exceeds one hour, it only prompts that the best tasting period of the corresponding food has been exceeded. When the time exceeds two hours, the staff is prompted to remove the corresponding food pick-and-place box and dispose of the food therein.

In this application, through the set timer, in cooperation with the trigger switch 7 and the alarm, the traceability of the best time limit for food appreciation can be realized. Since the trigger switch 7 of the present application is linked with the switch of the lid 3, no additional actions are required to open and close the trigger switch 7, which can improve convenience and avoid mistakes caused by forgetting.
