Description

Technical Field

[0001] This utility model relates to the field of drawer technology, and in particular to an automatic opening drawer cabinet, smart furniture and smart appliances. Background Technology

[0002] Traditionally, drawers are opened by manually pulling a handle on the outside. However, as users demand higher aesthetics from cabinets and drawer panels, they often remove the handle to achieve a cleaner, more sleek look. But eliminating the handle requires an alternative method for users to open the drawer.

[0003] Currently, there is a type of drawer structure on the market that can extend automatically. It uses an internal spring to provide the pushing force for the drawer to extend. However, this method still requires the user to manually press to trigger it. Therefore, the drawer cannot be opened if the user cannot press it manually, resulting in a low level of intelligence. Furthermore, it requires a large pressing force when the drawer is heavy, leading to a poor user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing drawer structures that cannot be opened automatically, have a low level of intelligence, and have a poor user experience, and to provide an automatic opening drawer cabinet, smart furniture, and smart appliances.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] In a first aspect, this utility model provides an automatically opening drawer cabinet, which includes a cabinet body, a drawer, and a drive system. The cabinet body forms a drawer cavity, and the drawer can be located in the drawer cavity and slidably connected to the cabinet body. The drive system includes a switching electromagnet, which is disposed on the cabinet body. The switching electromagnet includes a push rod, which can move toward and abut against the drawer when the switching electromagnet is energized, so as to push the drawer out of the drawer cavity.

[0007] The automatic opening drawer cabinet provided by this utility model uses an opening and closing electromagnet installed on the cabinet body. When energized, the electromagnet drives its push rod to move towards the drawer and abut against it, allowing the push rod to further push the drawer out of the drawer cavity. Thus, when the user needs to open the drawer, simply energizing the opening and closing electromagnet causes the push rod to push the drawer. Compared to existing methods that require manual pressing to open the drawer, the automatic opening drawer cabinet provided by this utility model eliminates the need for the user to press the drawer or apply significant pressure. Opening the drawer is achieved through electrical control, making operation more convenient, faster, and more intelligent, providing a better user experience.

[0008] Preferably, the drive system further includes a control module electrically connected to the opening and closing electromagnet; the drive system also includes a sensor for acquiring movement signals of a human body or object outside the drawer, the control module being electrically connected to the sensor to energize and de-energize the opening and closing electromagnet according to the movement signals; or, the drive system further includes a communication module for receiving external signals, the control module being electrically connected to the communication module to energize and de-energize the opening and closing electromagnet according to the external signals.

[0009] This design eliminates the need for users to directly open the drawers; instead, it automates the opening process remotely or through sensors, thereby enhancing the intelligence of the automatic drawer cabinet and improving the user experience.

[0010] Preferably, the opening and closing electromagnet further includes a housing, and a coil and an armature disposed inside the housing. A moving channel is formed on the housing, and the push rod passes through the moving channel and is connected to the armature. The moving channel extends toward the drawer. The coil can generate a magnetic field when energized, and drive the armature to move through the magnetic field force, so that the armature drives the push rod to move toward the drawer.

[0011] This design allows for the guidance and limiting of the push rod via the moving channel, making the push rod move more smoothly. The coil can provide sufficient thrust to the armature and push rod through the magnetic field, enabling the push rod to open the drawer.

[0012] Preferably, both ends of the push rod extend outside the housing, wherein one end of the push rod is positioned towards the drawer, and an elastic element is provided between the other end of the push rod and the housing.

[0013] This configuration allows the push rod to return to its initial position via an elastic element after the opening and closing electromagnet is de-energized, facilitating the next push action.

[0014] Preferably, the end of the push rod facing the drawer is provided with a flexible abutment.

[0015] This design prevents the push rod from colliding with the drawer surface and causing damage when it comes into contact with the drawer.

[0016] Preferably, the automatic opening drawer cabinet includes a limiting slide and a slider. One of the limiting slide and the slider is disposed on the cavity wall of the drawer cavity, and the other of the limiting slide and the slider is disposed on the outer side of the drawer. The slider is disposed in the limiting slide and is movable along the extension direction of the limiting slide. The extension direction of the limiting slide forms an angle with the horizontal direction, and the limiting slide extends downward at an angle in the direction toward the outside of the drawer cavity.

[0017] This design allows the drawer to utilize the horizontal component of its own weight to generate a pushing force as it moves out of the drawer cavity, ensuring a continuous outward tendency and allowing the drawer to slowly and automatically continue moving out.

[0018] Preferably, the drawer has a receiving cavity with a bottom wall, and the extending direction of the bottom wall is parallel to the extending direction of the limiting groove.

[0019] This design allows items placed in the accommodating cavity to tend to move forward, thus providing a forward pushing force to the drawer, enabling it to slowly and automatically move out.

[0020] Preferably, the receiving cavity has a front cavity wall that is inclined in a direction away from the drawer cavity in the direction from the bottom to the top of the receiving cavity.

[0021] This design allows items inside the accommodating cavity to exert forward and downward forces on the front cavity wall when they come into contact with it. The forward force provides a driving force for the drawer to move out slowly, while the downward force provides a certain degree of damping for the movement of the slider within the limiting groove, allowing the drawer to open slowly.

[0022] Preferably, the number of the opening and closing electromagnets is at least two, and the at least two opening and closing electromagnets are respectively disposed on opposite sides of the drawer.

[0023] This design ensures a uniform distribution of the pushing force, allowing the drawer to slide out more smoothly without tilting.

[0024] Secondly, this utility model also provides a smart furniture, characterized in that it includes the automatically opening drawer cabinet as described above.

[0025] The intelligent furniture described in this utility model has the same beneficial effects as the aforementioned automatic opening drawer cabinet, and will not be repeated here.

[0026] Thirdly, this utility model also provides a smart appliance, characterized in that it includes the automatically opening drawer cabinet as described above.

[0027] The intelligent electrical appliance described in this utility model has the same beneficial effects as the aforementioned automatic opening drawer cabinet, and will not be repeated here.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model. Attached Figure Description

[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] Traditionally, drawers are opened by manually pulling a handle on the outside. However, as users demand higher aesthetics from cabinets and drawer panels, they often remove the handle to achieve a cleaner, more sleek look. But eliminating the handle requires an alternative method for users to open the drawer.

[0041] Currently, there is a type of drawer structure on the market that can extend automatically. It uses an internal spring to provide the pushing force for the drawer to extend. However, this method still requires the user to manually press to trigger it. If the user cannot press manually, the drawer cannot be opened. The level of intelligence is low, and a large pressing force is required when the drawer is heavy, resulting in a poor user experience.

[0042] In view of the above situation, this utility model provides an automatic drawer cabinet, smart furniture and smart appliances, which can realize the automatic opening and closing of drawers without the user having to manually press, thereby further improving the intelligence of the drawer structure and the user experience.

[0043] The above is the core idea of ​​this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0044] like Figure 1-5 As shown, this embodiment of the utility model provides an automatic drawer cabinet, which includes a cabinet body 1 and a drawer 2. The cabinet body 1 has a drawer cavity 10, and the drawer 2 is located within the drawer cavity 10. For example, the cabinet body 1 has a drawer opening 11, which connects to the drawer cavity 10 inside the cabinet body 1, allowing the drawer 2 to be inserted into the drawer cavity 10 through the drawer opening 11.

[0045] Furthermore, the automatic drawer cabinet also includes a drive system, which includes a switching electromagnet 3 mounted on the cabinet body 1. The switching electromagnet 3 also includes a push rod 31, which can move toward the drawer 2 and abut against the drawer 2 when the switching electromagnet 3 is energized, thereby pushing the drawer 2 out of the drawer cavity 10.

[0046] Specifically, when drawer 2 is inside drawer cavity 10, the opening / closing electromagnet 3 is not energized, and drawer 2 remains stationary. When the user needs to open drawer 2, the opening / closing electromagnet 3 is energized. At this time, the push rod 31 can move towards drawer 2 and abut against drawer 2 through the triggering of the opening / closing electromagnet 3. Furthermore, during the continuous movement, the push rod 31 can continue to push drawer 2 after abutting it, causing drawer 2 to move out of drawer cavity 10.

[0047] In practical implementation, the energization and de-energization of the opening and closing electromagnet 3 can be achieved through a contact button on the cabinet 1. That is, after the button is triggered, the opening and closing electromagnet 3 can receive a current signal, thereby generating a driving force on the push rod 31, causing the push rod 31 to move. For example, this button can be a capacitive touch screen, that is, it can be triggered by manual contact without pressing. Of course, in other feasible methods, the opening and closing electromagnet 3 can also be energized and de-energized in other ways, such as triggering the generation of current through non-contact light or infrared sensors.

[0048] In summary, the automatic opening drawer cabinet provided by this utility model embodiment, by setting an opening and closing electromagnet 3 on the cabinet body 1, enables the opening and closing electromagnet 3 to drive its push rod 31 towards the drawer 2 and abut against the drawer 2 when energized, and enables the push rod 31 to further push the drawer 2 out of the drawer cavity 10. In this way, when the user needs to open the drawer 2, energizing the opening and closing electromagnet 3 will cause the push rod 31 to push the drawer 2. Compared with the existing method of opening the drawer 2 by manually pressing it, the automatic opening drawer cabinet provided by this utility model embodiment does not require the user to press the drawer 2 or provide a large pressing force. The drawer 2 can be opened by power control, which is more convenient, faster and more intelligent, and provides users with a better user experience.

[0049] It should be noted that the present utility model Figure 1 The structure of the automatic opening drawer cabinet provided in this paper is only a schematic diagram of a drawer cabinet structure and does not mean that the automatic opening drawer cabinet provided by this utility model can only be applied to... Figure 1 Structurally, in practice, the structure of the drawer cabinet may form other similar structures. Figure 1 Different structural forms may exist, but this does not affect the effectiveness of the automatic opening drawer cabinet.

[0050] Regarding the aforementioned power supply and de-energization of the opening and closing electromagnet 3, in one specific implementation, the drive system may further include a control module and a sensor. The control module is electrically connected to the opening and closing electromagnet 3, and the sensor is used to acquire movement signals of a human body or object outside the drawer 2. The control module is further electrically connected to the sensor to power the opening and closing electromagnet 3 according to the movement signals.

[0051] Specifically, the aforementioned movement signal refers to the digital electrical signal sent by the sensor to the control module. In other words, the sensor can acquire physical signals of movement of a person or object outside drawer 2, convert these physical signals into digital electrical signals, and then send these digital electrical signals to the control module. The control module reads the digital electrical signal sent by the sensor, performs logical judgment, and then sends a control command to the opening / closing solenoid 3. Upon receiving the control command from the control module, the opening / closing solenoid 3 energizes its coil 33, causing the push rod 31 to move towards drawer 2. Conversely, when the sensor does not detect a physical signal, the control module changes the control command, and the opening / closing solenoid 3 is de-energized.

[0052] For example, the sensor can be an infrared sensor, a light sensor, or an ultrasonic sensor. The specific connection methods and response principles of the sensor, control module, and opening / closing electromagnet 3 are existing technologies and will not be described in detail here.

[0053] In other embodiments, other methods can be used to switch the electromagnet on and off. For example, in another implementation, the drive system may further include a control module and a communication module, wherein the communication module is used to receive external signals, and the control module is electrically connected to the communication module to switch the opening and closing electromagnet 3 on and off according to the external signals.

[0054] Specifically, the external signal refers to a wireless signal sent to the automatically opening drawer cabinet via a communication device, such as a Bluetooth or radio frequency signal. The communication device could be a remote control or a mobile phone. After receiving the wireless signal, the communication module can parse it into commands recognizable by the control module and transmit the commands to the control module. The control module can then energize or de-energize the coil 33 of the opening / closing electromagnet 3 according to the commands.

[0055] By controlling the opening and closing of the electromagnet 3 in the above manner, the opening of drawer 2 can be automated through remote or sensor-based means, eliminating the need for the user to directly open drawer 2. This further enhances the intelligence of the automatic opening drawer cabinet and improves the user experience.

[0056] Of course, in other embodiments, different methods than the two mentioned above can also be used to achieve automatic opening of drawer 2.

[0057] Furthermore, the control of the opening and closing of the electromagnet 3 specifically refers to the control of the opening and closing of the coil 33 inside the electromagnet 3. Therefore, please refer to... Figure 4 and Figure 5As shown, in some embodiments, the opening and closing electromagnet 3 specifically includes a housing 32, and a coil 33 and an armature 34 disposed inside the housing 32. A moving channel 321 is formed on the housing 32, and a push rod 31 passes through the moving channel 321 and is connected to the armature 34 inside the housing 32. Furthermore, the moving channel 321 extends towards the drawer 2. When the coil 33 is energized, it generates a magnetic field, which drives the armature 34 to move, causing the armature 34 to move the push rod 31 towards the drawer 2.

[0058] For example, coil 33 is formed by winding insulated wire. Correspondingly, the automatic opening drawer cabinet is also equipped with a power source to supply current to coil 33, which is the energy source for forming a magnetic field. Armature 34 is made of magnetic material. Specifically, how coil 33 enables the movement of armature 34 and push rod 31, and how the control module achieves electrical connection, are all existing technologies and will not be elaborated here.

[0059] Based on the above, in some embodiments, both ends of the push rod 31 can extend to the outside of the housing 32, wherein one end of the push rod 31 is positioned towards the drawer 2, and the other end extends in a direction away from the drawer 2.

[0060] Furthermore, to ensure that the push rod 31 can return to its initial position when the electromagnet 3 is de-energized, in some embodiments, an elastic element 35 is provided between the other end of the push rod 31 and the housing 32. This elastic element 35 is in a free state when the coil 33 is not energized; that is, at this time, the elastic element 35 exerts no force on the housing 32 or the push rod 31. When the coil 33 is energized, the push rod 31 moves towards the drawer 2, and the elastic element 35 is stretched. In this state, the elastic element 35 exerts a pulling force on the push rod 31. However, the force exerted by the magnetic field generated by the energized coil 33 on the armature 34 and the push rod 31 is greater than this pulling force, allowing the push rod 31 to overcome the pulling force of the elastic element 35 and continue moving.

[0061] Correspondingly, when the coil 33 is de-energized, the magnetic field force immediately disappears, and the pulling force exerted by the elastic element 35 will drive the push rod 31 to move back until it returns to its initial position. In specific implementation, the elastic element 35 can be, for example, a spring, and a limiting platform 311 can be provided at the other end of the push rod 31 to fix the spring between the push rod 31 and the housing 32.

[0062] It should be noted that the specific structure of the opening and closing electromagnet 3 mentioned above is the internal structure of the opening and closing electromagnet 3 listed in this embodiment. In other embodiments, the opening and closing electromagnet 3 used in the automatic opening drawer cabinet of this embodiment can also adopt other structural forms. For example, the moving channel 321 can be formed on the guide inside the housing 32, and the elastic element 35 can be set inside the housing 32. In specific implementation, various opening and closing electromagnets 3 with different structures can be used flexibly according to the actual situation, as long as it can ensure that the push rod 31 mentioned above can move and push the drawer 2 out when the electromagnet is energized.

[0063] Furthermore, when installing opening and closing electromagnets 3 on the automatic opening drawer cabinet, at least two can be installed, with the at least two opening and closing electromagnets 3 positioned on opposite sides of the drawer 2. Moreover, at least one of the opening and closing electromagnets 3 is simultaneously energized, thereby simultaneously pushing the drawer 2. This ensures a uniform distribution of the pushing force, resulting in a smoother and more stable movement of the drawer 2 without tilting. In other embodiments, the at least two electromagnets can also be placed in other locations on the drawer 2.

[0064] In some embodiments, a flexible abutment may be provided at the end of the push rod 31 facing the drawer 2 to avoid damage to the surface of the drawer 2 when the push rod 31 abuts against the drawer 2.

[0065] To ensure the smooth movement of drawer 2 when the push rod 31 pushes it, in some embodiments, the automatic opening drawer cabinet also includes a limiting groove and a slider (not shown in the figure). The slider is located on the wall of the drawer cavity 10, and the limiting groove is located on the outer surface of drawer 2. The slider can be located within the limiting groove and can move along the extension direction of the limiting groove.

[0066] In practical implementation, the slider can be an elongated structure to further ensure the fit between the limiting groove and the slider. Multiple sliders can also be arranged along the extension direction of the limiting groove, thereby providing better guidance and limiting effects. In other embodiments, the positions of the limiting groove and the slider can be interchanged. That is, the limiting groove is set on the cavity wall of the drawer cavity 10, and the slider is set on the drawer 2, as long as the aforementioned sliding guiding function can be achieved.

[0067] In addition, for example, a set of limiting grooves and slider structures can be provided on each of the left and right sides of drawer 2 to further ensure the smoothness of drawer 2 movement.

[0068] Furthermore, in this embodiment, the extension direction of the limiting slide groove forms an angle with the horizontal direction, and the limiting slide groove extends downward in a direction toward the outside of the drawer cavity 10.

[0069] Since the push rod 31 cannot continue to push the drawer 2 to its limit position after pushing the drawer 2 outward due to its limited length, the user still needs to manually pull the drawer 2 open after it is partially opened. Therefore, with the above setting, the drawer 2 can use the horizontal component of its gravity to form a pushing force during the process of moving the drawer 2 outward, so that the drawer 2 can continue to have the tendency to move outward and the drawer 2 can continue to move outward slowly and automatically.

[0070] In practice, setting the included angle to a small angle, such as 5°, can achieve the above effect. Of course, in other embodiments, the included angle can also be greater than 5°, as long as the above effect can be achieved.

[0071] like Figure 2 As shown, the drawer 2 structure has a receiving cavity with an opening at the top. Specifically, the drawer 2 structure can include a front panel 22 of the body 21. The body 21 further includes a bottom plate 211, two side plates 212, and a rear plate 213. The two side plates 212 are located on either side of the bottom plate 211, and the rear plate 213 is connected to the rear edge of the bottom plate 211. Correspondingly, the front panel 22 and the rear plate 213 are positioned opposite each other, so that the bottom plate 211, the two side plates 212, the rear plate 213, and the front panel 22 together enclose the receiving cavity structure.

[0072] Building upon the above, to further enhance the automation and convenience of opening, in some embodiments, the extending direction of the bottom wall of the receiving cavity can be parallel to the extending direction of the limiting slide. That is, the bottom wall of the receiving cavity also extends at an angle, so that items placed in the receiving cavity tend to move forward, thereby providing a forward pushing force for drawer 2, allowing drawer 2 to slowly and automatically move out.

[0073] In practice, the base plate 211 of the main body 21 can be set at an inclination, so that the upper surface of the base plate 211 extends at an inclination.

[0074] When using the above-mentioned setup, in order to ensure that the drawer 2 remains stationary when it is not pulled out, a snap-fit ​​structure can be set between the drawer 2 and the cabinet 1. The snap-fit ​​structure can prevent the drawer 2 from moving outward to a certain extent, and only when the push rod 31 of the opening and closing electromagnet 3 pushes the drawer 2 can the force applied by the push rod 31 on the drawer 2 disengage the snap-fit ​​structure, thereby realizing the outward movement of the drawer 2.

[0075] Furthermore, in some embodiments, the front wall of the receiving cavity may be configured such that, along the direction from the bottom to the top of the receiving cavity, the front wall is inclined away from the drawer cavity 10. This configuration allows the item inside the receiving cavity to exert forward and downward forces on the front wall when it comes into contact with it. The forward force provides a driving force for the drawer 2 to move out slowly, while the downward force provides damping for the movement of the slider within the limiting groove, enabling the drawer 2 to open slowly.

[0076] In practice, the front panel 22 can be tilted so that the front cavity wall extends at an angle.
