Description

Technical Field

[0001] This invention relates to the field of product packaging technology, and specifically to a packaging box. Background Technology

[0002] Packaging boxes are used to package products, providing both protection and aesthetic appeal. In today's fiercely competitive market, product packaging has evolved from simply providing protection and integration to comprehensive packaging aimed at aesthetics and promotion. Whether packaging can attract consumers directly affects product sales.

[0003] Current packaging boxes are designed to be personalized and functional, serving as aids in product unpacking. However, when unpacking, the product is prone to colliding with the lid on top of the box, which can cause damage and may also cause the product to tip over. Summary of the Invention

[0004] In view of this, the present invention provides a packaging box to solve the problem that existing packaging boxes are prone to causing products to fall or tip over and be damaged during disassembly and assembly.

[0005] The present invention provides a packaging box, including a box body and a switching mechanism. The box body has an opening, and the switching mechanism is disposed in the box body. The switching mechanism includes a transmission component and an opening and closing component. The transmission component is connected to a product and can drive the product to enter and exit the box body through the opening. The opening and closing component is movable relative to the box body. The opening and closing component has a blocking state that blocks the opening and a avoiding state that avoids the opening.

[0006] Beneficial effects: When the product needs to be retrieved, the opening and closing component moves relative to the box body to a clearance state, allowing the opening and closing component to avoid the opening and open it. Then, the transmission component drives the product through the opening and removes it from the box body. When the product is put back, the transmission component drives the product through the opening and enters the box body. The opening and closing component moves relative to the box body to a blocking state, blocking the opening. The packaging box of this application can achieve convenient retrieval and storage of the product through the opening and closing mechanism. The opening and closing component can not only act as a lid to block the opening and prevent impurities and dust from entering, but also automatically avoid the opening through its movement relative to the box body. This solves the problem of damage or tipping caused by the product colliding with the lid on the top of the box body during the disassembly, assembly, and retrieval of the packaging box.

[0007] In one alternative implementation, the transmission assembly is drively connected to the opening / closing assembly, and both are driven by an actuating drive unit.

[0008] Beneficial effects: The transmission assembly and the opening / closing assembly are driven by a single actuator, which can improve structural compactness and reduce the number of power components.

[0009] In one optional embodiment, the transmission assembly includes a first guide rail and an in-and-out transmission part. The first guide rail is disposed inside the box and is arranged along the direction in which the product enters and exits the box. The actuation drive part drives the in-and-out transmission part to slide along the first guide rail. The in-and-out transmission part is connected to the opening and closing assembly and the product.

[0010] Beneficial effects: When the transmission component needs to move the product out of the box, the actuator drives the in-and-out transmission component to slide along the first guide rail toward the opening, thereby moving the opening and closing component relative to the box to a clearance state and moving the product out of the box through the opening, thus facilitating product retrieval through the opening. When the transmission component needs to move the product into the box, the actuator drives the in-and-out transmission component to slide away from the opening along the first guide rail, thereby moving the opening and closing component relative to the box to a blocking state and moving the product into the box, achieving blocking of the opening and storage of the product. The entire process is driven by a single actuator, resulting in good synchronization of movement and a simplified structure.

[0011] In one optional embodiment, the opening and closing assembly includes a second guide rail, an opening and closing transmission part, and a blocking part. The second guide rail is angled to and connected to the first guide rail. One end of the opening and closing transmission part is rotatably disposed on the second guide rail and can slide along the second guide rail. The other end of the opening and closing transmission part is hinged to the in-out transmission part. The blocking part is connected to the opening and closing transmission part and has the blocking state and the avoidance state.

[0012] Beneficial effects: When the actuator drives the in-and-out transmission unit to slide along the first guide rail toward the opening, the other end of the opening and closing transmission unit is subjected to a positive force from the in-and-out transmission unit and slides along the first guide rail toward the opening while rotating adaptively relative to the in-and-out transmission unit. One end of the opening and closing transmission unit is subjected to a component force along the direction of the second guide rail, which forces one end of the opening and closing transmission unit to slide along the second guide rail and rotate adaptively relative to the second guide rail. This causes the blocking part to move relative to the box to a clearance state. When the actuator drives the in-and-out transmission unit to slide away from the opening along the first guide rail, the other end of the opening and closing transmission unit is subjected to a reverse force from the in-and-out transmission unit and slides away from the opening along the first guide rail while rotating adaptively relative to the in-and-out transmission unit. One end of the opening and closing transmission unit is subjected to a component force along the direction of the second guide rail, which forces one end of the opening and closing transmission unit to slide along the second guide rail and rotate adaptively relative to the second guide rail. This causes the blocking part to move relative to the box to a blocking state.

[0013] In one alternative embodiment, the opening and closing assembly further includes a connecting portion, one end of which is connected to the opening and closing transmission portion, and the other end of which extends upward and is connected to the blocking portion.

[0014] Beneficial effects: The connecting part connects the blocking part and the opening and closing transmission part. When the opening and closing transmission part drives the connecting part to slide along the second guide rail, it simultaneously drives the blocking part connected to the connecting part to slide, so as to realize the switching of the blocking part between the avoidance state and the blocking state.

[0015] In one optional embodiment, two of each of the opening and closing transmission parts and the blocking parts are symmetrically arranged relative to the first guide rail. In the blocking state, the two blocking parts are brought together, and in the avoidance state, the two blocking parts are separated.

[0016] Beneficial effects: By symmetrically arranging two opening and closing transmission parts and two blocking parts relative to the first guide rail, when the transmission component moves, it can drive the two opening and closing transmission parts to slide away from each other or together, thereby driving the two blocking parts to separate to avoid the opening or driving the two blocking parts to come together to block the opening. The symmetrical arrangement of two parts can shorten the sliding stroke of the opening and closing transmission parts, thereby reducing the lateral size of the device and reducing the occupancy of the lateral space inside the box.

[0017] In one optional embodiment, the side of the shielding portion facing the transmission assembly is provided with a covering groove that matches the shape of the product. In the shielding state, the shielding portion covers the outer periphery of the product through the covering groove.

[0018] Beneficial effects: When shielded, the shielding part covers the outer periphery of the product through the covering groove, which can protect the product, reduce product bumps and collisions, and enhance the stability of the product when placed.

[0019] In one alternative implementation, the shielding portion is flush with the side facing the opening.

[0020] Beneficial effects: It facilitates the movement of the covering part inside the box, and the flush design also provides better coverage of the opening and improves aesthetics.

[0021] In one optional embodiment, the first guide rail is provided with a first slide groove, one end of the in-and-out transmission part is slidably connected to the first slide groove via a first slide post, the second guide rail is provided with a second slide groove communicating with the first slide groove, one end of the opening and closing transmission part is hinged to a second slide post, the second slide post is slidably connected to the second slide groove, and the other end of the opening and closing transmission part is hinged to the other end of the in-and-out transmission part via a hinge post, and the hinge post is slidably engaged with the first slide groove.

[0022] Beneficial effects: A first groove is provided on the first guide rail and a second groove is provided on the second guide rail that communicates with the first groove. When the transmission assembly and the opening and closing assembly move, the hinge pins at the other ends of the in-and-out transmission part and the opening and closing transmission part slide along the first groove, and the second sliding pin at one end of the opening and closing transmission part slides along the second groove, thereby improving the accuracy and stability of the sliding of the in-and-out transmission part and the opening and closing transmission part.

[0023] In one optional embodiment, the sliding stroke a of the in-and-out transmission part along the first slide groove is greater than or equal to the length b of the opening and closing transmission part, and the sliding stroke c of the opening and closing transmission part along the second slide groove is greater than or equal to the length b of the opening and closing transmission part.

[0024] Beneficial effect: It enables the opening and closing transmission part to slide to the maximum extent along the second slide groove, avoiding the situation where the opening and closing transmission part is stuck due to insufficient sliding stroke a or sliding stroke c.

[0025] In one alternative embodiment, the sliding stroke a of the in-and-out transmission unit along the first groove is greater than the farthest distance d from the top of the product to the opening, and the size of the opening is greater than the size of the product.

[0026] Beneficial effects: It enables the transmission components to slide the product into or through the opening to remove the product from the box, making it more convenient for users to retrieve the product.

[0027] In one optional embodiment, the lateral movement stroke of the blocking part is greater than half of the lateral width e of the product, and when the blocking part is in the blocking state, the distance f between the outer wall of the blocking part and the inner wall of the box is greater than or equal to the sliding stroke c of the opening and closing transmission part along the second slide groove.

[0028] Beneficial effects: The lateral movement stroke of the blocking part is limited to more than half of the lateral width e of the product, so that when the two blocking parts move laterally to the blocking state, they can close together to achieve seamless blocking of the opening. When the two blocking parts move laterally to the avoidance state, they can move to the sides of the product to avoid the product, making it convenient for the product to rise through the gap between the two blocking parts. At the same time, the distance f between the outer wall of the blocking part and the inner wall of the box is limited to be greater than or equal to the sliding stroke c of the opening and closing transmission part along the second slide groove, so that f has a sufficient size to facilitate the sliding of the opening and closing transmission part along the second slide groove, avoiding the situation where the opening and closing transmission part is stuck due to insufficient distance f between the outer wall of the blocking part and the inner wall of the box.

[0029] In one alternative embodiment, the transmission assembly is connected to a placement portion suitable for placing the product, the placement portion and the opening being disposed opposite each other.

[0030] Beneficial effects: The placement section facilitates product placement. The placement section and the opening are positioned opposite each other. When the transmission component drives the placement section to move toward the opening, the product on the placement section can be driven into the opening, making it convenient to retrieve the product.

[0031] In one optional embodiment, both the placement portion and the shielding portion are made of flexible cushioning material, or both the placement portion and the shielding portion are provided with a flexible cushioning layer.

[0032] Beneficial effects: The product can be protected on both the bottom and sides by using flexible cushioning materials, or the product can also be protected on both the bottom and sides by using flexible cushioning layers.

[0033] In one optional embodiment, the actuation drive unit includes an actuation knob, a drive gear, and a rack. The actuation knob is rotatably mounted on the housing via a rotating shaft. The drive gear is mounted inside the housing and connected to the rotating shaft. The rack is mounted on the in-out transmission unit and meshes with the drive gear.

[0034] Beneficial effects: When a product needs to be retrieved, rotating the knob clockwise causes the rotating shaft and drive gear to rotate clockwise simultaneously. Because the drive gear and rack mesh, the rack and the in-and-out transmission unit move synchronously toward the opening. When the product is returned, rotating the knob counterclockwise causes the rotating shaft and drive gear to rotate counterclockwise simultaneously. Because the drive gear and rack mesh, the rack and the in-and-out transmission unit move synchronously away from the opening. Therefore, by rotating the knob in different directions, the drive transmission components can be moved toward or away from the opening to allow the product to enter or exit the box, which is very convenient and also increases the user's enjoyment in retrieving the product.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The following combination Figures 1 to 7 The following describes embodiments of the present invention.

[0047] According to an embodiment of the present invention, a packaging box is provided, including a box body 1 and a switching mechanism. The box body 1 has an opening 11, and the switching mechanism is disposed inside the box body 1. The switching mechanism includes a transmission component 2 and an opening and closing component 3. The transmission component 2 is connected to a product 100 and can drive the product 100 to enter and exit the box body 1 through the opening 11. The opening and closing component 3 can move relative to the box body 1 and has a blocking state that blocks the opening 11 and a circumventing state that avoids the opening 11.

[0048] In this embodiment, when product 100 needs to be taken out, the opening and closing component 3 moves relative to the box body 1 to a clearance state, so that the opening and closing component 3 clears the opening 11 and opens the opening 11. Then, the transmission component 2 drives product 100 to move out of the box body 1 through the opening 11, so that product 100 can be taken out of the box body 1 for use. When product 100 is put back, the transmission component 2 drives product 100 to enter the box body 1 through the opening 11, and the opening and closing component 3 moves relative to the box body 1 to a blocking state, so that the opening and closing component 3 blocks the opening 11. The packaging box of this application can realize convenient access and storage of product 100 through the setting of the opening and closing mechanism. The setting of the opening and closing component 3 can not only act as a box lid to block the opening 11 and prevent impurities and dust from entering, but also automatically clear the opening 11 through the movement relative to the box body 1, solving the problem of product 100 colliding with the box lid on the top of the box body 1 during the process of taking out product 100, causing damage or tipping.

[0049] like Figure 1 and Figure 6 As shown, in this embodiment, the box body 1 is a hollow shell, which is suitable for accommodating the product 100 and the switch box mechanism. In terms of shape, the box body 1 can be a geometric, circular, or elliptical shell. In this embodiment, the box body 1 is preferably a square shell.

[0050] The opening 11 facilitates the removal of the product 100 from the box 1. Therefore, the size of the opening 11 should be larger than the size of the product 100, so that there is a gap between the product 100 and the inner wall of the opening 11 when the product 100 passes through it, making it convenient to hold the product 100. The opening 11 can be provided on the top or side of the box 1. This embodiment takes the opening 11 being provided on the top of the box 1 as an example for detailed description.

[0051] In terms of shape, the opening 11 can be set as a circular opening, an elliptical opening, or a geometric opening, depending on the specific needs. In this embodiment, the opening 11 is preferably set as a rectangular opening, and the length and width of the rectangular opening are both greater than the dimensions of the product 100 along the length and width directions.

[0052] like Figure 2 and Figure 3 As shown, the transmission component 2 can drive the product 100 toward the opening 11 when the product 100 needs to be taken out, so that the user can take the product 100 out of the box 1 through the opening 11. The transmission component 2 can also drive the product 100 away from the opening 11 when the product 100 needs to be stored, so as to realize the storage of the product 100.

[0053] When the product 100 needs to be taken out, the opening and closing component 3 can move relative to the box body 1 to a clearance state to open the opening 11, making it convenient for the user to take out the product 100 through the opening 11. When the product 100 needs to be stored, the opening and closing component 3 can also move relative to the box body 1 to a blocking state to cover the opening 11 and prevent external dust and water stains from entering the box body 1 through the opening 11 and contaminating the product 100.

[0054] Furthermore, in order to improve structural compactness and reduce the number of power components, in this embodiment, the transmission assembly 2 and the opening and closing assembly 3 are connected by transmission, and both are driven by an execution drive unit 4.

[0055] In terms of specific configuration, in this embodiment, the transmission component 2 includes a first guide rail 21 and an in-and-out transmission part 22. The first guide rail 21 is disposed inside the box body 1 and is disposed along the direction of the product 100 entering and exiting the box body 1. The execution drive part 4 drives the in-and-out transmission part 22 to slide along the first guide rail 21. The in-and-out transmission part 22 is connected to the opening and closing component 3 and the product 100.

[0056] In the above configuration, when the transmission component 2 needs to move the product 100 out of the box 1, the execution drive unit 4 drives the in-and-out transmission unit 22 to slide along the first guide rail 21 toward the opening 11, thereby moving the opening and closing component 3 relative to the box 1 to a clearance state and moving the product 100 out of the box 1 through the opening 11, thus facilitating the retrieval of the product 100 through the opening 11. When the transmission component 2 needs to move the product 100 into the box 1, the execution drive unit 4 drives the in-and-out transmission unit 22 to slide along the first guide rail 21 away from the opening 11, thereby moving the opening and closing component 3 relative to the box 1 to a blocking state and moving the product 100 into the box 1, thus achieving the blocking of the opening 11 and the storage of the product 100. The entire process is driven by one execution drive unit 4, resulting in good synchronization of movement and a simplified structure.

[0057] In this embodiment, the opening and closing assembly 3 includes a second guide rail 31, an opening and closing transmission part 32, and a blocking part 33. The second guide rail 31 is set at an angle to the first guide rail 21 and is connected to the first guide rail 21. One end of the opening and closing transmission part 32 is rotatably disposed on the second guide rail 31 and can slide along the second guide rail 31. The other end of the opening and closing transmission part 32 is hinged to the in-out transmission part 22. The blocking part 33 is connected to the opening and closing transmission part 32 and has a blocking state and an avoidance state.

[0058] In the above configuration, when the drive unit 4 drives the in-and-out transmission unit 22 to slide along the first guide rail 21 toward the opening 11, the other end of the opening and closing transmission unit 32 is subjected to a positive force from the in-and-out transmission unit 22, causing it to slide along the first guide rail 21 toward the opening 11 and rotate adaptively relative to the in-and-out transmission unit 22. One end of the opening and closing transmission unit 32 is subjected to a component force along the second guide rail 31, thereby forcing one end of the opening and closing transmission unit 32 to slide along the second guide rail 31 and rotate adaptively relative to the second guide rail 31. This causes the blocking part 33 to move relative to the box body 1 to an avoidance position. When the drive unit 4 drives the in-and-out transmission unit 22 to slide along the first guide rail 21 away from the opening 11, the other end of the opening and closing transmission unit 32 is subjected to a downward reverse force from the in-and-out transmission unit 22 and slides along the first guide rail 21 away from the opening 11 and rotates adaptively relative to the in-and-out transmission unit 22. One end of the opening and closing transmission unit 32 is subjected to a component force along the direction of the second guide rail 31, thereby forcing one end of the opening and closing transmission unit 32 to slide along the second guide rail 31 and rotate adaptively relative to the second guide rail 31, thereby driving the blocking part 33 to move relative to the box 1 to the blocking state.

[0059] In this embodiment, the first guide rail 21 is provided with a first slide groove 211, one end of the in-and-out transmission part 22 is slidably connected to the first slide groove 211 via a first slide post 221, the second guide rail 31 is provided with a second slide groove 311 communicating with the first slide groove 211, one end of the opening and closing transmission part 32 is hinged to a second slide post 321, the second slide post 321 is slidably connected to the second slide groove 311, and the other end of the opening and closing transmission part 32 is hinged to the other end of the in-and-out transmission part 22 via a hinge post 222, and the hinge post 222 is slidably engaged with the first slide groove 211.

[0060] The above configuration includes a first slide groove 211 on the first guide rail 21 and a second slide groove 311 on the second guide rail 31 that communicates with the first slide groove 211. This allows the transmission assembly 2 and the opening / closing assembly 3 to move, so that when they move, the hinge pins 222 at the other end of the transmission part 22 and the opening / closing transmission part 32 slide along the first slide groove 211, and the second slide pin 321 at one end of the opening / closing transmission part 32 slides along the second slide groove 311, thereby improving the accuracy and stability of the sliding of the transmission part 22 and the opening / closing transmission part 32.

[0061] Specifically, such as Figure 2 and Figure 3As shown, the first guide rail 21 can be vertically arranged inside the box 1, and the in-and-out transmission part 22 moves up and down along the first guide rail 21. The second guide rail 31 can be arranged perpendicular to the first guide rail 21, and the opening and closing transmission part 32 moves laterally along the first guide rail 21. The first guide rail 21 and the second guide rail 31 are connected to form a T-shaped guide rail. The bottom of the T-shaped guide rail extends to a first connecting surface that is fixedly connected to the bottom wall of the box 1, and the two sides of the T-shaped guide rail respectively extend to a second connecting surface that is fixedly connected to the inner wall of the box 1, so as to connect and fix the first guide rail 21 and the second guide rail 31 as a whole to the box 1 and ensure stability. It can be understood here that one end of the in-and-out transmission part 22 refers to the bottom of the in-and-out transmission part 22, and the other end of the in-and-out transmission part 22 refers to the top of the in-and-out transmission part 22.

[0062] Of course, in some embodiments, the first guide rail 21 may be arranged horizontally or obliquely inside the box 1, and the second guide rail 31 may be arranged at other angles to the first guide rail 21, not limited to this embodiment.

[0063] The first slide groove 211 is a vertical strip hole along the height direction of the first guide rail 21, and the second slide groove 311 is a horizontal strip hole along the length direction of the second guide rail 31. The first slide post 221 and the hinge post 222 are both slidably engaged in the vertical strip hole, and the second slide post 321 is slidably engaged in the horizontal strip hole.

[0064] It should be noted that the hinge column 222 can slide only along the first slide groove 211. In this case, both the in-and-out transmission part 22 and the opening and closing transmission part 32 can be rotatably sleeved on the outer periphery of the hinge column 222. Alternatively, the hinge column 222 can slide along the first slide groove 211 and rotate within the first slide groove 211. In this case, the in-and-out transmission part 22 can be rotatably sleeved on the outer periphery of the hinge column 222, and the opening and closing transmission part 32 is fixedly connected to the hinge column 222. The second slide column 321 can slide only along the second slide groove 311. In this case, the opening and closing transmission part 32 can be rotatably sleeved on the outer periphery of the second slide column 321. Alternatively, the second slide column 321 can slide along the second slide groove 311 and rotate within the second slide groove 311. In this case, the opening and closing transmission part 32 is fixedly connected to the outer periphery of the second slide column 321.

[0065] In terms of shape, in this embodiment, the in-and-out transmission part 22 can be configured as an L-shaped transmission plate. The vertical portion of the L-shaped transmission plate is provided with hinge pins 222 and first sliding pins 221 spaced vertically. The horizontal portion of the L-shaped transmission plate is used to connect with the product 100. The opening and closing transmission part 32 can be configured as a rectangular transmission plate. The second sliding pin 321, which is hinged at one end of the rectangular transmission plate, is slidably disposed in the second sliding groove 311. The other end of the rectangular transmission plate is hinged to the L-shaped transmission plate through the hinge pins 222.

[0066] It should be noted that, since the second slide groove 311 and the first slide groove 211 are connected, the sliding stroke of the second slide post 321 along the second slide groove 311 is the distance from the end of the second slide groove 311 to the connection point between the second slide groove 311 and the first slide groove 211. The sliding stroke of the hinge post 222 along the first slide groove 211 is the distance from the hinge post 222 to the connection point between the first slide groove 211 and the second slide groove 311 when the product 100 is at its lowest position.

[0067] To facilitate understanding of the driving principle of this embodiment, the force conditions of the hinge column 222 and the second sliding column 321 will now be analyzed, as follows: Figure 4 As shown, Figure 4 The diagram shows the forces acting on the hinge column 222 and the second sliding column 321. During the upward movement of the transmission assembly 2, the hinge column 222 is subjected to an upward thrust F1, which forces the hinge column 222 to slide upward. During the downward movement of the transmission assembly 2, the hinge column 222 is subjected to a downward pull F2, which forces the hinge column 222 to slide downward.

[0068] like Figure 4 As shown, the second sliding column 321 is subjected to an upward thrust Fa during the upward movement of the transmission assembly 2. This upward thrust Fa can be decomposed into a partial thrust Fa1 along the second slide groove 311 and a partial thrust Fa2 perpendicular to the second slide groove 311. Due to the limitation of the second sliding column 321 by the second slide groove 311, even if the partial thrust Fa2 exists, the second sliding column 321 will not move in the direction perpendicular to the second slide groove 311. Under the push of the partial thrust Fa1, the second sliding column 321 drives the opening and closing transmission part 32 to slide along the direction of the second slide groove 311, thereby driving the blocking part 33 to move to the avoidance state to avoid the opening 11. Conversely, the second sliding column 321 moves downward during the upward movement of the transmission assembly 2. During the descent, it is subjected to a downward pulling force Fb. The downward pulling force Fb can be decomposed into a pulling force Fb1 along the second slide groove 311 (the direction of Fb1 is opposite to the direction of Fa1) and a pulling force Fb2 perpendicular to the second slide groove 311 (the direction of Fb2 is opposite to the direction of Fa2). Since the second slide groove 311 limits the second slide column 321, even if there is a pulling force Fb2, the second slide column 321 will not move in the direction perpendicular to the second slide groove 311. Under the pull of the pulling force Fb1, the second slide column 321 drives the opening and closing transmission part 32 to slide along the direction of the second slide groove 311, thereby driving the blocking part 33 to move to the blocking state to block the opening 11.

[0069] Furthermore, in this embodiment, the transmission assembly 2 is connected to a placement part 24 suitable for placing the product 100, and the placement part 24 and the opening 11 are arranged opposite to each other. The placement part 24 facilitates the placement of the product 100. The placement part 24 and the opening 11 are arranged opposite to each other. When the transmission assembly 2 drives the placement part 24 to move toward the opening 11, the product 100 on the placement part 24 can be driven into the opening 11, making it convenient to take out the product 100.

[0070] In this embodiment, the placement part 24 is located below the opening 11. The placement part 24 is fixedly connected to the horizontal part of the L-shaped transmission plate. The top of the placement part 24 is provided with a placement groove suitable for placing the product 100. The product 100 can be snapped into the placement groove to achieve fixation.

[0071] Optionally, the placement part 24 can be configured as a rectangular structure, with the placement groove located at the center of the rectangular structure, and the shape of the placement groove matching the shape of the product 100. For example, if the product 100 has a cylindrical shape, the placement groove can be configured as a circular groove.

[0072] In this embodiment, the opening and closing assembly 3 further includes a connecting portion 34. One end of the connecting portion 34 is connected to the opening and closing transmission portion 32, and the other end of the connecting portion 34 extends upward and connects to the blocking portion 33. The connecting portion 34 connects the blocking portion 33 and the opening and closing transmission portion 32. When the opening and closing transmission portion 32 drives the connecting portion 34 to slide along the second guide rail 31, it simultaneously drives the blocking portion 33 connected to the connecting portion 34 to slide, thereby realizing the switching of the blocking portion 33 between the avoidance state and the blocking state.

[0073] It is understandable that since the opening and closing transmission part 32 will change angle during the movement, in order to avoid the connection part 34 tilting due to the angle change, in this embodiment, the second sliding column 321 is set to be able to slide only along the second sliding groove 311, and the connection part 34 and the second sliding column 321 are connected to ensure that the connecting column can only slide along the second sliding groove 311 with the second sliding column 321 and does not rotate.

[0074] The connecting part 34 can be configured as a “]” shaped structure, with the top of the “] shaped structure connected and fixed to the shielding part 33, and the bottom of the “] shaped structure connected and fixed to the second sliding column 321.

[0075] In terms of quantity, in this embodiment, two opening / closing transmission parts 32 and two blocking parts 33 are symmetrically arranged relative to the first guide rail 21. In the blocking state, the two blocking parts 33 are side by side, and in the avoidance state, the two blocking parts 33 are separated. By symmetrically arranging two opening / closing transmission parts 32 and two blocking parts 33 relative to the first guide rail 21, when the transmission component 2 moves, it can drive the two opening / closing transmission parts 32 to slide away from each other or side by side, thereby driving the two blocking parts 33 to separate to avoid the opening 11 or driving the two blocking parts 33 to side by side to block the opening 11. The symmetrical arrangement of two parts can shorten the sliding stroke of the opening / closing transmission parts 32, thereby reducing the lateral size of the device and reducing the occupancy of the lateral space inside the box 1.

[0076] The combined size of the two blocking portions 33 is larger than the size of the opening 11, so as to completely block the opening 11. In this embodiment, the blocking portions 33 can be set as rectangles, the combined length of the two blocking portions 33 is greater than the length of the opening 11, and the combined width of the two blocking portions 33 is greater than the width of the opening 11.

[0077] Furthermore, the lower part of the shielding portion 33, facing the transmission assembly 2, is provided with a covering groove 331 that matches the shape of the product 100. In the shielding state, the shielding portion 33 covers the outer periphery of the product 100 through the covering groove 331. In the shielding state, the shielding portion 33 covering the outer periphery of the product 100 through the covering groove 331 can protect the product 100, reduce the impact on the product 100, and enhance the stability of the product 100 when placed.

[0078] The shape of the covering groove 331 matches the shape of the product 100. For example, when the overall appearance of the product 100 is cylindrical, the covering groove 331 is set as a semi-circular groove. When the two blocking parts 33 are brought together, the two semi-circular grooves on them are joined to form a complete circular groove, so as to completely cover the outer periphery of the cylindrical product 100.

[0079] It is understandable that the covering groove 331 is not connected to the side of the blocking part 33 facing the opening 11, so that the blocking part 33 can better block the opening 11.

[0080] The shielding part 33 is flush with the side facing the opening 11 so that the shielding part 33 can move inside the box 1. The flush position can also provide a better shielding effect on the opening 11 and improve the aesthetics.

[0081] In terms of materials, in this embodiment, both the placement part 24 and the shielding part 33 can be made of flexible cushioning material to protect the bottom and sides of the product 100. Alternatively, both the placement part 24 and the shielding part 33 can be provided with a flexible cushioning layer to protect the bottom and sides of the product 100.

[0082] For example, the flexible cushioning material or flexible cushioning layer can be made of materials such as rubber, silicone, or sponge.

[0083] In addition, such as Figure 3 and Figure 7 As shown, this embodiment also includes some parameter designs, as detailed below:

[0084] The sliding stroke a of the in-and-out transmission unit 22 along the first slide groove 211 is greater than or equal to the length b of the opening and closing transmission unit 32, and the sliding stroke c of the opening and closing transmission unit 32 along the second slide groove 311 is greater than or equal to the length b of the opening and closing transmission unit 32. This arrangement allows the opening and closing transmission unit 32 to slide to the maximum extent along the second slide groove 311, avoiding the situation where the opening and closing transmission unit 32 gets stuck due to insufficient sliding stroke a or sliding stroke c.

[0085] Furthermore, the sliding stroke 'a' of the in-and-out transmission unit 22 along the first slide groove 211 is greater than the farthest distance 'd' from the top of the product 100 to the opening 11, and the size of the opening 11 is greater than the size of the product 100. This arrangement allows the transmission assembly 2 to drive the product 100 to slide at least partially into or through the opening 11, thereby enabling the product 100 to be removed from the box 1, making it more convenient for the user to retrieve the product 100.

[0086] It should be noted that when the opening 11 is located at the top of the box body 1 and the first guide rail 21 is vertically arranged, the farthest distance d is the distance from the top surface of the product 100 to the opening 11 when the inlet / outlet transmission unit 22 drives the product 100 to descend along the first guide rail 21 to the bottom of the box body 1 or to the stop position; when the opening 11 is located on the side of the box body 1 and the first guide rail 21 is horizontally arranged, the farthest distance d is the distance from the side of the product 100 facing the opening 11 to the opening 11 when the inlet / outlet transmission unit 22 drives the product 100 to move along the first guide rail 21 away from the opening 11 to the stop position.

[0087] Furthermore, the lateral movement stroke of the blocking part 33 is greater than half of the lateral width e of the product 100. When the blocking part 33 is in the blocking state, the distance f between the outer wall of the blocking part 33 and the inner wall of the box body 1 is greater than or equal to the sliding stroke c of the opening and closing transmission part 32 along the second slide groove 311. This configuration limits the lateral travel of the blocking part 33 to be greater than half the lateral width e of the product 100. This allows the two blocking parts 33 to come together seamlessly to block the opening 11 when they move laterally to the blocking state, and to move to the sides of the product 100 when they move laterally to the avoidance state, thus avoiding the product 100 and facilitating its ascent through the gap between the two blocking parts 33. At the same time, the distance f between the outer wall of the blocking part 33 and the inner wall of the box 1 is greater than or equal to the sliding travel c of the opening and closing transmission part 32 along the second slide groove 311. This ensures that f has a sufficient size to facilitate the sliding of the opening and closing transmission part 32 along the second slide groove 311, preventing the opening and closing transmission part 32 from getting stuck due to insufficient distance f between the outer wall of the blocking part 33 and the inner wall of the box 1.

[0088] It should be noted that, in this embodiment, the sliding stroke a of the in-and-out transmission part 22 along the first slide groove 211 is equal to the distance from the hinge post 222 to the connection point of the first slide groove 211 and the second slide groove 311 when the product 100 is at its lowest position; the length b of the opening and closing transmission part 32 is equal to the straight length from the second slide post 321 to the hinge post 222; the sliding stroke c of the opening and closing transmission part 32 along the second slide groove 311 is equal to the distance from the end of the second slide groove 311 to the connection point of the second slide groove 311 and the first slide groove 211; the distance f between the outer wall of the shielding part 33 and the inner wall of the box body 1 is equal to the distance from the side wall of the shielding part 33 opposite to the covering groove 331 to the inner wall of the box body 1 corresponding to that side wall.

[0089] By limiting the parameters mentioned above, the opening or closing of the switch box mechanism can be better realized. When the width e of product 100 is changed, the corresponding parameters can be modified through the various related dimensions mentioned above to make it applicable to products 100 of different sizes.

[0090] It should be clarified here that the execution drive unit 4 set in this embodiment is part of the transmission assembly 2. The execution drive unit 4 is in transmission cooperation with the inlet and outlet transmission unit 22 in the transmission assembly 2 to drive the inlet and outlet transmission unit 22 to transmit power. The inlet and outlet transmission unit 22 can simultaneously drive the opening and closing assembly 3 and the product 100 to move.

[0091] like Figure 2 , Figure 5 and Figure 6As shown, in this embodiment, the execution drive unit 4 includes an execution knob 41, a drive gear 43, and a rack 223. The execution knob 41 is rotatably mounted on the housing 1 via a rotating shaft 42. The drive gear 43 is mounted inside the housing 1 and connected to the rotating shaft 42. The rack 223 is mounted on the in-and-out transmission unit 22 and meshes with the drive gear 43.

[0092] With the above setup, when product 100 needs to be taken out, rotating the execution knob 41 clockwise causes the rotating shaft 42 and drive gear 43 to rotate clockwise synchronously. Since the drive gear 43 meshes with the rack 223, the rack 223 and the in-and-out transmission part 22 move synchronously toward the opening 11. When product 100 is put back, rotating the execution knob 41 counterclockwise causes the rotating shaft 42 and drive gear 43 to rotate counterclockwise synchronously. Since the drive gear 43 meshes with the rack 223, the rack 223 and the in-and-out transmission part 22 move synchronously away from the opening 11. Therefore, by rotating the execution knob 41 in different directions, the drive transmission component 2 can be moved toward or away from the opening 11 to allow product 100 to enter or exit the box 1, which is very convenient and also increases the user's enjoyment of taking out product 100.

[0093] Specifically, the side wall of the box 1 is provided with a through hole, and the rotating shaft 42 is installed in the through hole through a bearing to reduce rotational wear. One end of the rotating shaft 42 is located outside the box 1 and the other end is located inside the box 1. The actuation knob 41 is fixedly connected to the rotating shaft 42 outside the box 1, and the drive gear 43 is fixedly connected to the rotating shaft 42 inside the box 1.

[0094] The rack 223 is vertically arranged along the edge of the transmission section 22. The length of the rack 223 limits the sliding stroke a of the transmission section 22. Therefore, the length of the rack 223 should be reasonably set, preferably greater than or equal to the sliding stroke a.

[0095] It should be noted that the stopping position of product 100 is achieved by the self-locking of the actuator 4, that is, the actuator knob 41 is set as a self-locking knob, which can position the product 100 when it is not turned. Since the structure and implementation principle of the self-locking knob are existing technologies, they will not be described in detail in this embodiment.

[0096] To facilitate understanding of the packaging box in this embodiment, please refer to the instruction manual. Figures 1 to 7 The usage process is described as follows:

[0097] When product 100 needs to be taken, the actuator knob 41 is rotated clockwise, which drives the rotating shaft 42 and the drive gear 43 to rotate clockwise synchronously. Since the drive gear 43 and the rack 223 mesh, the rack 223 and the inlet / outlet transmission part 22 are driven to rise and slide synchronously along the first slide groove 211 of the first guide rail 21. This causes the other end of the opening and closing transmission part 32 to slide upward along the first slide groove 211 and rotate adaptively relative to the inlet / outlet transmission part 22 due to the upward thrust from the inlet / outlet transmission part 22. One end of the opening and closing transmission part 32 is subjected to the partial thrust Fa1 along the direction of the second guide rail 31, which forces one end of the opening and closing transmission part 32 to slide along the second slide groove 311 of the second guide rail 31 and rotate adaptively relative to the second guide rail 31. This causes the symmetrically arranged connecting parts 34 on both sides to move away from each other, so that the two adjacent blocking parts 33 separate and move to the avoidance state. At the same time, the inlet / outlet transmission part 22 drives the product 100 on the placement part 24 to rise to the opening 11, and the user can take the product 100 through the opening 11.

[0098] When product 100 needs to be stored in box 1, first place product 100 in placement part 24 through opening 11, then rotate the execution knob 41 counterclockwise, causing rotating shaft 42 and drive gear 43 to rotate counterclockwise synchronously. Since drive gear 43 meshes with rack 223, rack 223 and inlet / outlet transmission part 22 are driven to descend synchronously along the first slide groove 211 of first guide rail 21. This causes the other end of opening / closing transmission part 32 to slide downward along the first slide groove 211 under the downward pulling force from inlet / outlet transmission part 22, and to rotate adaptively relative to inlet / outlet transmission part 22, thus opening / closing transmission part 32. One end of the moving part 32 is subjected to a pulling force Fb1 along the direction of the second guide rail 31, which forces one end of the opening and closing transmission part 32 to slide along the second slide groove 311 of the second guide rail 31 and rotate adaptively relative to the second guide rail 31. This causes the connecting parts 34 arranged symmetrically on both sides to move closer together, so that the two separate blocking parts 33 move together to the blocking state to completely block the opening 11. The two blocking parts 33 cover the outer periphery of the product 100 through the covering groove 331. At the same time, the in-and-out transmission part 22 drives the product 100 on the placement part 24 to descend to the lowest position.

[0099] Of course, the above description is merely the optimal technical solution for this embodiment. Furthermore:

[0100] In some embodiments, the transmission assembly 2 and the opening / closing assembly 3 may be configured with independent actuators 4, which drive the movement of the transmission assembly 2 and the opening / closing assembly 3 respectively.

[0101] In some embodiments, the drive unit 4 may also be configured as a transmission form consisting of a motor and a lead screw or a chain and a sprocket.

[0102] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
