Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a drive component and a refrigeration device. Background Technology

[0002] Currently, refrigerator doors and cabinets are generally sealed using magnetic door seals. The door seal is installed on the door, forming a single unit. The door is held in place by the magnetic force of the door seal, achieving a seal between the door and cabinet, thus keeping the refrigerator warm. However, because the contact area between the door seal and the cabinet is relatively long, and the seal creates a closed space inside the refrigerator, opening the door requires considerable force due to the magnetic force and the negative pressure inside. This makes it difficult for the elderly and children to open the door, especially when both hands are full, requiring them to put down their items before opening the door, increasing inconvenience and wasting time and effort.

[0003] In related technologies, the automatic opening of doors is achieved through electromagnetic drive and motor drive. However, when the door is opened automatically through electromagnetic drive, the electromagnetic drive structure is relatively thick, resulting in low versatility. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, a first aspect of the present invention provides a driving component.

[0006] A second aspect of the present invention also provides a refrigeration device.

[0007] In view of this, a first aspect of the present invention provides a driving assembly, comprising: a push rod; a plurality of magnetic components, the plurality of magnetic components being spaced apart along the length direction of the push rod, each magnetic component having a first through hole, the plurality of first through holes of the plurality of magnetic components being correspondingly arranged, the push rod passing through the first through holes of the plurality of magnetic components, and the plurality of magnetic components being capable of driving the push rod to move along the length direction of the push rod.

[0008] The driving assembly provided by this invention includes a push rod and multiple magnetic components. Each magnetic component has a first through hole. The multiple magnetic components are spaced apart along the length of the push rod, such that the multiple first through holes of the multiple magnetic components are correspondingly arranged. This allows the push rod to pass through the multiple first through holes of the multiple magnetic components, meaning the multiple magnetic components are connected in series on the push rod. Under the action of the multiple magnetic components, the push rod can move along its length, thereby enabling the driving assembly to push other components. Simultaneously, driving the push rod with multiple magnetic components reduces the overall thickness of the driving assembly, improves its versatility, reduces the heat generation of individual magnetic components, and enhances the performance of the driving assembly. Furthermore, the spaced arrangement of multiple magnetic components along the length of the push rod effectively prevents magnetic leakage or short circuits between adjacent magnetic components.

[0009] It should be noted that multiple magnetic components are spaced apart along the length of the push rod, so that multiple magnetic components are connected in series on the push rod. The thrust generated by multiple magnetic components is superimposed. Therefore, the number of magnetic components can be increased or decreased according to the actual application scenario of the drive component, thereby improving the versatility of the drive component.

[0010] In practical applications, magnetic components include electromagnets. It is understood that an electromagnet generates magnetism when energized, and under the drive of this magnetism, it can push a push rod to move, thereby causing the push rod to move along its length.

[0011] Furthermore, when the magnetic component is energized, it can drive the push rod to move forward along the length of the push rod. When the magnetic component is de-energized, it stops generating thrust on the push rod. Alternatively, when the magnetic component is energized, it can drive the push rod to move forward along the length of the push rod. After the drive function of the drive component is realized through the movement of the push rod, the energizing signal of the magnetic component is switched to make the magnetic component drive the push rod to move backward along the length of the push rod, so that the push rod is reset, thereby realizing the next drive.

[0012] Understandably, in related technologies, when the door is opened by electromagnetic drive, the electromagnet body is quite thick. Due to the strict height restrictions on the refrigeration equipment during transportation and installation, its versatility is not high. However, the technical solution proposed in this application, by connecting multiple magnetic components in series and superimposing the thrust generated by each magnetic component, reduces the overall thickness of the drive component compared to the related technology that uses a single electromagnet to drive the push rod. This improves the versatility of the drive component. At the same time, under the condition of achieving the same driving force, driving the push rod by multiple magnetic components reduces the heat generation of a single magnetic component and improves the performance of the drive component.

[0013] The driving component provided by the present invention may also have the following additional technical features:

[0014] In some possible designs, any magnetic component includes: an electromagnet having a first through hole; a mounting portion including a mounting cavity, the electromagnet being disposed within the mounting cavity, the mounting cavity having a second through hole communicating with the first through hole, and a push rod passing through the second through hole and movably connected to the mounting cavity.

[0015] In this design, each magnetic component includes an electromagnet and a mounting portion. The mounting portion includes a mounting cavity, and the electromagnet is disposed within the mounting cavity to prevent it from affecting other structures. The electromagnet has a first through hole, and the mounting portion has a second through hole, which communicates with the first through hole. Therefore, the push rod can pass through both the first and second through holes within the electromagnet, and the electromagnet's action drives the push rod to move linearly, thus achieving the driving function of the drive component.

[0016] It is understandable that when an electromagnet is energized, it generates a magnetic field, which drives the push rod to move linearly under the action of the magnetic field, thereby realizing the driving function of the drive component.

[0017] In some possible designs, the electromagnet includes: a bracket with a first through hole; a coil disposed on the bracket, the coil including two terminals mounted on a mounting part, and multiple coils of multiple magnetic components connected in parallel.

[0018] In this design, the electromagnet includes a support and a coil. The coil is mounted on the support, and when energized, it generates a magnetic field, enabling the electromagnet to drive the push rod. The coil has two terminals, which connect it to the power supply unit. The terminals are mounted on the support, securing them and improving connection efficiency. Furthermore, the coils of multiple magnetic components are connected in parallel, meaning that multiple magnetic components are connected to the voltage in parallel. This ensures that multiple magnetic components generate magnetism simultaneously, thereby synchronously driving the push rod and guaranteeing timely action, thus fulfilling the driving function of the drive components.

[0019] Understandably, although the resistance values ​​of each coil may differ in actual production, the parallel connection of multiple coil voltages allows all coils to generate electromagnetic fields simultaneously. Even if the resistance values ​​of the electromagnets differ or there are assembly errors, it will not affect the synchronization of the push rod, nor will it affect the superposition of forces. Specifically, the magnetic field of each electromagnet can generate a thrust on the push rod, which in turn causes the thrust on the push rod to be superimposed, thereby achieving the driving function of the drive component through the push rod.

[0020] Furthermore, each bracket is provided with two mounting slots, and the two terminals are respectively locked in the two mounting slots.

[0021] In some possible designs, the drive assembly also includes a control unit connected to the terminals, which is used to control the coil to be energized or de-energized.

[0022] In this design, the drive assembly also includes a control unit. The control unit is connected to the terminals of the coil, thereby controlling the energization or de-energization of the coil.

[0023] In some possible designs, the electromagnet includes a solenoid electromagnet.

[0024] In this design, the electromagnet includes a solenoid electromagnet. When the solenoid electromagnet is energized, it becomes magnetic and can drive the push rod to move under the influence of the magnetic field, thus realizing the driving function of the drive component. When the solenoid electromagnet is de-energized, its magnetism disappears, thereby ensuring the reliability of the mechanism.

[0025] In some possible designs, multiple mounting parts of multiple magnetic components are connected sequentially.

[0026] In this design, multiple mounting parts of multiple magnetic components are connected sequentially along the length of the push rod, which improves the structural strength of the drive assembly, ensures that the multiple first through holes of multiple magnetic components correspond, and thus ensures the reliability of the push rod movement.

[0027] In some possible designs, the mounting section includes a steel plate that at least surrounds the periphery of the electromagnet.

[0028] In this design, the mounting part includes a steel plate, which is at least placed around the electromagnet, that is, the steel plate surrounds the electromagnet. On the one hand, this can improve the strength and reliability of the structure, and on the other hand, the steel plate can effectively prevent magnetic leakage.

[0029] It is understandable that there are gaps between multiple mounting cavities, and the spacing can effectively prevent magnetic leakage and magnetic short circuits.

[0030] In some possible designs, the mounting section is equipped with shock-absorbing pads.

[0031] In this design, the mounting section is equipped with shock-absorbing pads. When the drive assembly is installed on the refrigeration equipment, the drive assembly is connected to the refrigeration equipment through the shock-absorbing pads, which can prevent the vibration generated when the push rod moves from being transmitted to the refrigeration equipment and generating noise, thereby improving the performance of the refrigeration equipment.

[0032] In some possible designs, the push rod includes: a rod section comprising multiple connecting rods and multiple ferromagnetic rods, the connecting rods and multiple ferromagnetic rods being interleaved, and multiple magnetic components protruding from both ends of the rod section along the length of the push rod.

[0033] In this design, the push rod includes a rod section, which in turn includes multiple connecting rods and multiple ferromagnetic rods. These connecting rods and ferromagnetic rods are interconnected in an alternating manner, so that adjacent ferromagnetic rods are linked together by the connecting rods, thus preventing mutual interference of magnetic flux and ensuring that the magnetic potential energy at each position is the same. Furthermore, along the length of the push rod, both ends of the rod section protrude from multiple magnetic components, preventing the push rod from detaching from the first through-hole of the magnetic components during movement, thus ensuring the reliability of the drive assembly structure.

[0034] In practical applications, the connecting rod includes a stainless steel connecting rod.

[0035] Understandably, multiple connecting rods and multiple ferromagnetic rods are interleaved, so that adjacent ferromagnetic rods are connected by connecting rods, thereby avoiding the situation where magnetic flux interferes with each other due to direct connection between adjacent ferromagnetic rods, thus ensuring the driving effect on the push rod.

[0036] It should be noted that both ends of the rod protrude from the entire structure composed of all the magnetic components to ensure that all the magnetic components can drive the rod to move and to ensure that the rod will not detach from the magnetic components, thereby improving the reliability of the drive components.

[0037] In some possible designs, the push rod also includes a sleeve fitted onto the rod, with the sleeve positioned between two adjacent magnetic components.

[0038] In this design, the push rod also includes a sleeve, which is fitted onto the rod to prevent the rod from being exposed and affecting its appearance. The sleeve is located between two adjacent magnetic components, ensuring the spacing between them and thus preventing magnetic short circuits between adjacent magnetic components.

[0039] Understandably, the rod can slide within the sleeve, allowing it to move along the length of the push rod.

[0040] In practical applications, the two ends of the sleeve are connected to the mounting parts corresponding to the two adjacent magnetic components, respectively.

[0041] In some possible designs, the drive assembly also includes: an elastic element fitted onto the rod; a retaining ring located at the first end of the rod; the elastic element being connected to the retaining ring and the mounting portion of the magnetic assembly.

[0042] In this design, the drive assembly also includes an elastic element and a retaining ring. The retaining ring is located at the first end of the rod, and the elastic element is sleeved on the rod, with both ends connected to the retaining ring and the mounting part of the magnetic assembly, respectively. Thus, when the magnetic assembly is energized, it generates a magnetic field, which drives the rod to move along its length, thereby driving the corresponding component. At the same time, the first end of the push rod moves towards the adjacent magnetic assembly, compressing the elastic element and generating a driving force. When the magnetic assembly is de-energized, the magnetic field of the magnetic assembly disappears, and the rod returns to its original position under the action of the elastic element.

[0043] It is understandable that, among the multiple magnetic components, including the magnetic component closest to the first end of the rod, one end of the elastic element is mounted on the magnetic component closest to the first end of the rod.

[0044] Accordingly, the rod also includes a second end. The first end and the second end of the rod are two opposite ends of the rod. The second end of the rod is located closer to the component to be driven, while the first end of the rod is located away from the component to be driven.

[0045] In practical applications, elastic elements include springs.

[0046] In some possible designs, the rod is a one-piece structure.

[0047] In this design, the rod is a one-piece structure. This one-piece structure improves the connection strength between the connecting rod and the ferromagnetic rod, preventing the connecting rod and the ferromagnetic rod from separating during the driving function and causing the drive assembly to fail. Furthermore, designing the connecting rod and the ferromagnetic rod as a one-piece structure also facilitates the installation of the drive assembly.

[0048] In some possible designs, the drive assembly also includes a buffer located at the second end of the rod.

[0049] In this design, the drive assembly also includes a buffer, which is disposed on the second end of the rod. In this way, when the rod drives the part to be driven to move, the rod contacts the part to be driven through the buffer. This can avoid noise when contacting the part and also prevent the rod from scratching the surface of the part to be driven when driving it.

[0050] Specifically, the second end of the rod is positioned corresponding to the component to be driven. After the magnetic component is energized, the push rod moves towards the component to be driven, causing the second end of the rod to gradually approach the component until it drives the component to move. After the magnetic component is de-energized, the push rod returns to its original position under the action of the elastic element.

[0051] Furthermore, the cushioning element includes a rubber pad or a silicone pad.

[0052] According to a second aspect of the present invention, a refrigeration device is also provided, comprising: a drive component as described in any of the above-described technical solutions.

[0053] The refrigeration device provided in the second aspect of the present invention, having all the beneficial effects of the driving component proposed in any of the above-mentioned technical solutions, has all the benefits of the driving component.

[0054] In some possible designs, the refrigeration equipment also includes: a housing with an opening; and a door connected to the housing for opening or closing the opening, wherein a drive assembly is mounted on the housing, a second end of a push rod is correspondingly positioned to the door, and multiple magnetic components drive the push rod to open the door.

[0055] In this design, the refrigeration equipment also includes a cabinet and a door. The cabinet has an opening, and the door is rotatably connected to the cabinet, allowing the door to open or close the opening. The drive assembly is mounted on the cabinet, improving the reliability of the connection between the drive assembly and the refrigeration equipment. The second end of the push rod is positioned corresponding to the door; thus, multiple magnetic components drive the push rod towards the door, causing the push rod to push open the door through its second end, achieving automated door opening and reducing the difficulty of opening the door.

[0056] Furthermore, the magnetic component is an electromagnet. When the magnetic component is energized, it generates a magnetic field, which drives the push rod to move towards the door, causing the second end of the push rod to push open the door, reducing the difficulty of opening the door and thus improving the user experience of the refrigeration equipment.

[0057] Understandably, refrigeration equipment doors are equipped with door seal components, which are positioned between the door and the cabinet to ensure a tight seal and prevent cold air leakage. Because of the attraction between the door seal component and the cabinet, users need to exert considerable force to open the door, which is inconvenient when users have items in their hands or when elderly or children are opening the door. The drive component proposed in this application automates the door opening process, reducing the difficulty of opening the door and achieving automated door opening.

[0058] In some possible designs, the refrigeration equipment also includes: a housing with an opening; and a door connected to the housing for opening or closing the opening, wherein a drive assembly is mounted on the door, a second end of a push rod is correspondingly disposed to the housing, and multiple magnetic components drive the push rod to push the housing to open the door.

[0059] In this design, the refrigeration equipment also includes a cabinet and a door. The cabinet has an opening, and the door is rotatably connected to the cabinet, allowing the door to open or close the opening. A drive assembly is mounted on the door, and the second end of a push rod is aligned with the cabinet. When the drive assembly is activated, the push rod moves towards the cabinet, causing the door to rotate relative to the cabinet, thus opening the opening. This automates door opening and reduces the difficulty of opening the door.

[0060] Furthermore, the magnetic component is an electromagnet. When the magnetic component is energized, it generates a magnetic field, which drives the push rod to move towards the cabinet, causing the door to move relative to the cabinet, thereby opening the cabinet and reducing the difficulty of opening the door, thus improving the user experience of the refrigeration equipment.

[0061] Understandably, refrigeration equipment doors are equipped with door seal components, which are positioned between the door and the cabinet to ensure a tight seal and prevent cold air leakage. However, due to the attraction between the door seal component and the cabinet, users need to exert considerable force to open the door, which is inconvenient when users have items in their hands or when elderly or children are opening the door. The drive component proposed in this application automates the door opening process, reducing the difficulty of opening the door and achieving automated door opening.

[0062] Specifically, refrigeration equipment also includes refrigerators.

[0073] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0074] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0075] The following reference Figures 1 to 6 The present invention describes a drive assembly and a cooling device according to some embodiments thereof.

[0076] like Figure 1 and Figure 2 As shown, according to a first embodiment of the present invention, the present invention provides a driving assembly, including: a push rod 1 and a plurality of magnetic components 2.

[0077] Specifically, multiple magnetic components 2 are arranged at intervals along the length direction of the push rod 1, each magnetic component 2 is provided with a first through hole, and multiple first through holes of multiple magnetic components 2 are arranged correspondingly. The push rod 1 passes through the first through holes of multiple magnetic components 2, and the multiple magnetic components 2 can drive the push rod 1 to move along the length direction of the push rod 1.

[0078] The driving assembly provided by this invention includes a push rod 1 and multiple magnetic components 2. Each magnetic component 2 has a first through hole. The multiple magnetic components 2 are spaced apart along the length of the push rod 1, such that the multiple first through holes of the multiple magnetic components 2 are correspondingly arranged. This allows the push rod 1 to pass through the multiple first through holes of the multiple magnetic components 2, meaning the multiple magnetic components 2 are connected in series on the push rod 1. Under the action of the multiple magnetic components 2, the push rod 1 can move along its length, thereby enabling the driving assembly to push other components. Simultaneously, by using multiple magnetic components 2 to drive the push rod 1, the overall thickness of the driving assembly is reduced, improving its versatility and reducing the heat generation of individual magnetic components 2, thus enhancing the performance of the driving assembly. Furthermore, the spaced arrangement of the multiple magnetic components 2 along the length of the push rod 1 effectively prevents magnetic leakage or short circuits between adjacent magnetic components 2.

[0079] It should be noted that multiple magnetic components 2 are arranged at intervals along the length of the push rod 1, so that multiple magnetic components 2 are connected in series on the push rod 1. The thrust generated by multiple magnetic components 2 is superimposed. Therefore, the number of magnetic components 2 can be increased or decreased according to the actual application scenario of the drive component, thereby improving the versatility of the drive component.

[0080] In specific applications, the magnetic component 2 includes an electromagnet 20. It is understood that the electromagnet 20 generates magnetism when energized, and under the drive of this magnetism, it can push the push rod 1 to move, thereby causing the push rod 1 to move along its length.

[0081] Furthermore, when the magnetic component 2 is energized, it can drive the push rod 1 to move forward along the length direction of the push rod 1. When the magnetic component 2 is de-energized, it stops generating thrust on the push rod 1. Alternatively, when the magnetic component 2 is energized, it can drive the push rod 1 to move forward along the length direction of the push rod 1. After the driving function of the driving component is realized through the movement of the push rod 1, the energizing signal of the magnetic component 2 is switched so that the magnetic component 2 drives the push rod 1 to move backward along the length direction of the push rod 1, thereby resetting the push rod 1 and realizing the next drive.

[0082] Understandably, in related technologies, refrigeration equipment uses a single electromagnet to directly open the door, and the electromagnet itself is quite thick. Due to the strict limitations on the height of the refrigeration equipment during transportation and installation, its versatility is not high. However, the embodiment proposed in this application connects multiple magnetic components 2 in series, and the thrust generated by each magnetic component 2 is superimposed. Compared with the related technologies that use a single electromagnet to drive the push rod 1, the embodiment proposed in this application reduces the overall thickness of the driving component and improves its versatility. At the same time, by using multiple magnetic components 2 to drive the push rod 1, the heat generated by a single magnetic component 2 is reduced, and the performance of the driving component is improved.

[0083] According to a second embodiment of the present invention, based on the first embodiment described above, any magnetic component 2 further includes: an electromagnet 20 and a mounting portion 22. Specifically, the electromagnet 20 is provided with a first through hole; the mounting portion 22 includes a mounting cavity 222, the electromagnet 20 is disposed in the mounting cavity 222, wherein the mounting cavity 222 is provided with a second through hole 220, the second through hole 220 communicating with the first through hole, and the push rod 1 passes through the second through hole 220 and is movably connected to the mounting cavity 222.

[0084] In this design, any magnetic component 2 includes an electromagnet 20 and a mounting portion 22. The mounting portion 22 includes a mounting cavity 222, and the electromagnet 20 is disposed within the mounting cavity 222 of the mounting portion 22 to prevent the electromagnet 20 from affecting other structures. The electromagnet 20 has a first through hole, and the mounting portion 22 has a second through hole 220, which communicates with the first through hole. Therefore, the push rod 1 can pass through the first and second through holes 220 and be inserted into the electromagnet 20. The electromagnet 20 then drives the push rod 1 to move linearly, thus realizing the driving function of the drive component.

[0085] Specifically, each mounting part 22 is provided with two second through holes 220. Along the length direction of the push rod 1, the two second through holes 220 are arranged opposite to each other, so that the push rod 1 can pass through the first through hole and the second through hole 220 to pass through the electromagnet 20 and the mounting part 22, thereby realizing the linear movement of the push rod 1.

[0086] It is understandable that when the electromagnet 20 is energized, it generates a magnetic field, which drives the push rod 1 to move linearly under the action of the magnetic field, thereby realizing the driving function of the drive component.

[0087] According to a third embodiment of the present invention, based on the above-described embodiment two, the electromagnet 20 further includes a support and a coil. Specifically, the support is provided with a first through hole; the coil is disposed on the support and includes two terminals 200, which are mounted on the mounting portion 22, and multiple coils of multiple magnetic components 2 are arranged in parallel.

[0088] like Figure 2 As shown, in this design, the electromagnet 20 includes a support and a coil. The coil is mounted on the support, and when energized, it generates a magnetic field, enabling the electromagnet 20 to drive the push rod 1. The coil includes two terminals 200, which connect the coil to the power supply unit. The two terminals 200 are mounted on the support, fixing them and improving connection efficiency. The coils of multiple magnetic components 2 are connected in parallel, meaning that multiple magnetic components 2 are connected to the voltage in parallel. This ensures that multiple magnetic components 2 generate magnetism simultaneously, thereby synchronously driving the push rod 1 and ensuring timely action of the push rod 1, thus realizing the driving function of the drive components.

[0089] Understandably, although the resistance values ​​of each coil may differ in actual production, the parallel connection of multiple coil voltages allows all coils to generate electromagnetic fields simultaneously. Even if the resistance values ​​of the electromagnets 20 differ or there are assembly errors, it will not affect the synchronization of the push rod 1, nor will it affect the superposition of forces. Specifically, the magnetic field of each electromagnet 20 can generate a thrust on the push rod 1, thereby superimposing the thrusts on the push rod 1 to achieve the driving function of the drive component.

[0090] In practical applications, the bracket is provided with a mounting slot, and the terminal 200 is snapped into the mounting slot. In this way, the terminal 200 can be pre-installed in the mounting slot after the electromagnet 20 is installed, and then the terminal 200 is connected to the power supply, which improves the installation efficiency.

[0091] Furthermore, each bracket is provided with two mounting slots, and the two terminals 200 are respectively locked in the two mounting slots.

[0092] According to a fourth embodiment of the present invention, based on the above-described third embodiment, the driving assembly further includes a control unit connected to the terminal 200, which is used to control the coil to be energized or de-energized.

[0093] In this design, the drive assembly also includes a control unit. The control unit is connected to the coil terminals 200, thereby controlling the energization or de-energization of the coil.

[0094] Understandably, when the control coil is energized, it generates an electromagnetic field, which drives push rod 1 to move linearly along its length, thus realizing the driving function of the drive assembly. When the control coil is de-energized, the magnetic field generated by the coil disappears, and push rod 1 resets. The push rod 1 can be reset via a structure such as the elastic element 14, or by controlling the current signal within the control coil, allowing push rod 1 to reciprocate within the first through hole, thereby achieving both the pushing and resetting functions of push rod 1.

[0095] According to a fifth embodiment of the present invention, based on the above-described fourth embodiment, the electromagnet 20 further includes a solenoid electromagnet.

[0096] In this design, the electromagnet 20 includes a solenoid electromagnet. When the solenoid electromagnet is energized, it becomes magnetic and can drive the push rod 1 to move under the action of the magnetic field, thus realizing the driving function of the drive component. When the solenoid electromagnet is de-energized, its magnetism disappears, thereby ensuring the reliability of the mechanism.

[0097] like Figure 1 and Figure 2As shown, according to the sixth embodiment of the present invention, based on any one of the embodiments two to five above, the plurality of mounting portions 22 of the plurality of magnetic components 2 are further connected in sequence.

[0098] In this design, multiple mounting parts 22 of multiple magnetic components 2 are connected sequentially along the length of the push rod 1, which improves the structural strength of the drive assembly, ensures that the multiple first through holes of multiple magnetic components 2 correspond to each other, and thus ensures the reliability of the movement of the push rod 1.

[0099] In a specific application, the mounting portion 22 of any magnetic component 2 also includes a connecting plate, which is located between two adjacent mounting cavities 222 and connected to the two adjacent mounting cavities 222 to realize the connection between the two adjacent mounting portions 22.

[0100] like Figure 1 and Figure 2 As shown, according to the seventh embodiment of the present invention, based on any one of the embodiments two to five above, the mounting part 22 further includes a steel plate, which at least surrounds the periphery of the electromagnet 20.

[0101] In this design, the mounting part 22 includes a steel plate, which is at least disposed around the electromagnet 20, that is, the steel plate surrounds the electromagnet 20. On the one hand, this can improve the strength and reliability of the structure, and on the other hand, the steel plate can effectively prevent magnetic leakage.

[0102] It is understandable that there are gaps between the multiple mounting cavities 222, and the setting of the gaps can effectively prevent magnetic leakage and magnetic short circuits.

[0103] The spacing between the mounting cavities 222 is set according to the actual situation. Specifically, while ensuring the overall length, the spacing between adjacent mounting cavities 222 is made large enough to avoid magnetic short circuits.

[0104] Furthermore, steel plates are arranged around the periphery, top, and bottom of the electromagnet 20 so that the electromagnet 20 is completely enclosed within the mounting cavity 222, further preventing magnetic leakage and preventing dust from entering the electromagnet 20 and affecting its performance. At the same time, the electromagnet 20 is also prevented from being exposed, which would affect its aesthetics.

[0105] like Figure 1 and Figure 2 As shown, according to the eighth embodiment of the present invention, based on any one of the embodiments two to five above, the mounting part 22 is further provided with a shock-absorbing pad 3.

[0106] In this design, the mounting part 22 is equipped with a shock-absorbing pad 3. When the drive component is installed on the refrigeration equipment, the drive component is connected to the refrigeration equipment through the shock-absorbing pad 3, thereby preventing the vibration generated when the push rod 1 moves from being transmitted to the refrigeration equipment and generating noise, thus improving the performance of the refrigeration equipment.

[0107] In specific applications, the shock-absorbing pad 3 includes a rubber pad or a silicone pad. The setting of the rubber pad or silicone pad can prevent the vibration generated by the push rod 1 from being transmitted to the refrigeration equipment and affecting the performance of the refrigeration equipment, and can also reduce the noise generated by the movement of the push rod 1.

[0108] like Figure 3 and Figure 4 As shown, according to the ninth embodiment of the present invention, based on any of the above embodiments, the push rod 1 further includes: a rod portion 10, the rod portion 10 including a plurality of connecting rods 102 and a plurality of ferromagnetic rods 104, the plurality of connecting rods 102 and the plurality of ferromagnetic rods 104 being alternately connected, and along the length direction of the push rod 1, the two ends of the rod portion 10 protrude from a plurality of magnetic components 2.

[0109] In this design, the push rod 1 includes a rod portion 10, which comprises multiple connecting rods 102 and multiple ferromagnetic rods 104. The connecting rods 102 and ferromagnetic rods 104 are staggered, so that adjacent ferromagnetic rods 104 are connected together through the connecting rods 102, thereby preventing mutual interference of magnetic flux and ensuring that the magnetic potential energy at each position is the same. Along the length of the push rod 1, both ends of the rod portion 10 protrude from multiple magnetic components 2, preventing the push rod 1 from disengaging from the first through-hole of the magnetic component 2 during movement, thus ensuring the reliability of the drive component structure.

[0110] In specific applications, link 102 includes a stainless steel connecting rod.

[0111] It is understandable that multiple connecting rods 102 and multiple ferromagnetic rods 104 are connected in an alternating manner, so that two adjacent ferromagnetic rods 104 are connected by connecting rods 102, thereby avoiding the situation where two adjacent ferromagnetic rods 104 are directly connected and their magnetic flux interferes with each other, thus ensuring the driving effect on push rod 1.

[0112] It should be noted that the two ends of the rod 10 protrude from the whole composed of all the magnetic components 2, so as to ensure that all the magnetic components 2 can drive the rod 10 to move and to ensure that the rod 10 will not be dislodged from the magnetic components 2, thereby improving the reliability of the drive components.

[0113] like Figure 1 As shown, according to the tenth embodiment of the present invention, based on the above embodiment nine, the push rod 1 further includes a sleeve 12, which is sleeved on the rod portion 10, and the sleeve 12 is located between two adjacent magnetic components 2.

[0114] In this design, the push rod 1 also includes a sleeve 12, which is fitted onto the rod portion 10 to prevent the rod portion 10 from being exposed and affecting aesthetics. The sleeve 12 is located between two adjacent magnetic components 2, ensuring the spacing between them and thus preventing magnetic short circuits between adjacent magnetic components 2.

[0115] Understandably, the rod 10 can slide within the sleeve 12 so that the rod 10 moves along the length of the push rod 1.

[0116] In practical applications, the two ends of the sleeve 12 are respectively connected to the mounting parts 22 corresponding to the two adjacent magnetic components 2.

[0117] like Figure 1 and Figure 2 As shown, according to the eleventh embodiment of the present invention, based on the above embodiment nine, the driving assembly further includes: an elastic member 14 and a retaining ring 16, the elastic member 14 being sleeved on the rod portion 10; the retaining ring 16 being disposed at the first end of the rod portion 10, and the elastic member 14 being connected to the retaining ring 16 and the mounting portion 22 of the magnetic assembly 2.

[0118] In this design, the drive assembly also includes an elastic element 14 and a retaining ring 16, such as Figure 5 and Figure 6 As shown, the retaining ring 16 is disposed at the first end of the rod 10, and the elastic element 14 is sleeved on the rod 10, with both ends connected to the retaining ring 16 and the mounting part 22 of the magnetic component 2, respectively. Thus, when the magnetic component 2 is energized, the magnetic component 2 generates a magnetic field, which drives the rod 10 to move, causing the rod 10 to move along its length, thereby driving the corresponding component. At the same time, the first end of the push rod 1 moves toward the adjacent magnetic component 2, causing the elastic element 14 to be compressed and generating a driving force. When the magnetic component 2 is de-energized, the magnetic field of the magnetic component 2 disappears, and the rod 10 is reset under the action of the elastic element 14.

[0119] It is understood that, among the multiple magnetic components 2, including the magnetic component 2 closest to the first end of the rod 10, one end of the elastic member 14 is mounted on the magnetic component 2 closest to the first end of the rod 10.

[0120] Accordingly, the rod 10 also includes a second end. The first end and the second end of the rod 10 are two opposite ends disposed on the rod 10. Relative to the component to be driven, the second end of the rod 10 is disposed close to the component to be driven, and the first end of the rod 10 is disposed away from the component to be driven.

[0121] In specific applications, the elastic element 14 includes a spring.

[0122] According to the twelfth embodiment of the present invention, based on the above-described embodiment nine, the rod 10 is further characterized as an integral structure.

[0123] In this design, the rod 10 is a one-piece structure. This one-piece structure improves the connection strength between the connecting rod 102 and the ferromagnetic rod 104, preventing the connecting rod 102 and the ferromagnetic rod 104 from separating during the driving function of the rod 10, which could cause the drive assembly to fail. Furthermore, designing the connecting rod 102 and the ferromagnetic rod 104 as a one-piece structure also facilitates the installation of the drive assembly.

[0124] like Figure 5 and Figure 6 As shown, in some possible designs, the drive assembly also includes a buffer 4, located at the second end of the rod 10.

[0125] In this design, the drive assembly also includes a buffer 4, which is disposed on the second end of the rod 10. In this way, when the rod 10 drives the component to be driven to move, the rod 10 contacts the component to be driven through the buffer 4. This can avoid noise when contacting the component and also prevent the rod 10 from scratching the surface of the component to be driven when driving it.

[0126] Specifically, the second end of the rod 10 is positioned corresponding to the component to be driven. After the magnetic component 2 is energized, the push rod 1 is driven to move towards the component to be driven, so that the second end of the rod 10 gradually approaches the component to be driven until the component to be driven moves, thus enabling the component to move. After the magnetic component 2 is de-energized, the push rod 1 is reset under the action of the elastic element 14.

[0127] Furthermore, the buffer 4 includes a rubber pad or a silicone pad.

[0128] According to a thirteenth embodiment of the present invention, based on any of the above embodiments, a further provision is made: a refrigeration device comprising: a drive component as described in any of the above embodiments.

[0129] The refrigeration device provided in the thirteenth embodiment of the present invention has all the beneficial effects of the drive component because it includes the drive component proposed in any of the above embodiments.

[0130] According to the fourteenth embodiment of the present invention, based on the above-described thirteenth embodiment, the refrigeration equipment further includes: a housing and a door. The housing includes an opening; the door is connected to the housing and is used to open or close the opening, wherein a drive assembly is mounted on the housing, the second end of the push rod 1 is correspondingly disposed with respect to the door, and a plurality of magnetic components 2 drive the push rod 1 to open the door.

[0131] In this design, the refrigeration equipment also includes a cabinet and a door. The cabinet has an opening, and the door is rotatably connected to the cabinet, allowing the door to open or close the opening. The drive assembly is mounted on the cabinet, improving the reliability of the connection between the drive assembly and the refrigeration equipment. The second end of the push rod 1 is positioned corresponding to the door. Thus, multiple magnetic components 2 drive the push rod 1 towards the door, causing the push rod 1 to push open the door through its second end, achieving automated door opening and reducing the difficulty of opening the door.

[0132] Furthermore, the magnetic component 2 is an electromagnet. When the magnetic component 2 is energized, it generates a magnetic field, which drives the push rod 1 to move towards the door, causing the second end of the push rod 1 to push open the door, reducing the difficulty of opening the door and thus improving the user experience of the refrigeration equipment.

[0133] Understandably, refrigeration equipment doors are equipped with door seal components, which are positioned between the door and the cabinet to ensure a tight seal and prevent cold air leakage. Because of the attraction between the door seal component and the cabinet, users need to exert considerable force to open the door, which is inconvenient when users have items in their hands or when elderly or children are opening the door. The drive component proposed in this application automates the door opening process, reducing the difficulty of opening the door and achieving automated door opening.

[0134] Furthermore, the refrigeration equipment also includes an input device, which is connected to the control unit of the drive assembly. When the user needs to open the door, the input device sends a command to the control unit of the drive assembly, thereby controlling the energization or de-energization of the magnetic component 2. When the magnetic component 2 is energized, the push rod 1 moves to open the door. When the magnetic component 2 is de-energized, the push rod 1 resets.

[0135] According to the fifteenth embodiment of the present invention, based on the above-described thirteenth embodiment, the refrigeration equipment further includes: a housing and a door. The housing includes an opening; the door is connected to the housing and is used to open or close the opening, wherein a drive assembly is mounted on the door, the second end of the push rod 1 is correspondingly disposed with respect to the housing, and a plurality of magnetic components 2 drive the push rod 1 to push the housing to open the door.

[0136] In this design, the refrigeration equipment also includes a cabinet and a door. The cabinet has an opening, and the door is rotatably connected to the cabinet, allowing the door to open or close the opening. A drive assembly is mounted on the door, and the second end of the push rod 1 is aligned with the cabinet. Thus, when the drive assembly is activated, the push rod 1 moves towards the cabinet, causing the door to rotate relative to the cabinet, thereby opening the opening and automating the door opening process, reducing the difficulty of opening the door.

[0137] Furthermore, the magnetic component 2 is an electromagnet. When the magnetic component 2 is energized, it generates a magnetic field, which drives the push rod 1 to move towards the cabinet, causing the door to move relative to the cabinet, thereby opening the cabinet opening, reducing the difficulty of opening the door and improving the user experience of the refrigeration equipment.

[0138] Understandably, refrigeration equipment doors are equipped with door seal components, which are positioned between the door and the cabinet to ensure a tight seal and prevent cold air leakage. However, due to the attraction between the door seal component and the cabinet, users need to exert considerable force to open the door, which is inconvenient when users have items in their hands or when elderly or children are opening the door. The drive component proposed in this application automates the door opening process, reducing the difficulty of opening the door and achieving automated door opening.

[0139] Furthermore, the refrigeration equipment also includes an input device, which is connected to the control unit of the drive assembly. When the user needs to open the door, the input device sends a command to the control unit of the drive assembly, thereby controlling the energization or de-energization of the magnetic component 2. When the magnetic component 2 is energized, the push rod 1 moves to open the door. When the magnetic component 2 is de-energized, the push rod 1 resets.

[0140] Specifically, the refrigeration equipment also includes a refrigeration system, which is used to cool the enclosure.

[0141] In a specific application, this invention provides a driving assembly for a refrigeration device. The driving assembly includes multiple magnetic components 2 and a push rod 1. Each magnetic component 2 includes an electromagnet, with multiple electromagnets connected in series, as shown in the specific structure below. Figure 1 and Figure 2 As shown.

[0142] Furthermore, each magnetic component 2 consists of a solenoid electromagnet, a mounting part 22, and a terminal 200, with the mounting part 22 including a metal plate. The push rod 1 mainly consists of a stainless steel connecting rod 102 and a ferromagnetic rod 104. To ensure synchronization, each solenoid electromagnet is connected in parallel to the same input voltage. Although the resistance values ​​of each solenoid electromagnet 20 differ in actual production, they can all generate electromagnetic fields simultaneously, and each push rod 1 can simultaneously generate an attractive force F (surface + end face), thus ensuring the synchronous superposition of the attractive forces F.

[0143]

[0144] Meanwhile, the push rod 1 is composed of a stainless steel connecting rod 102 and a ferromagnetic rod 104 to prevent mutual interference of magnetic flux and ensure that the magnetic potential energy at each position is the same. Each electromagnet 20 is an independent module, and the number can be increased or decreased according to the force requirements. At the same time, the push rod 1 can also be customized according to different needs.

[0145] The drive assembly proposed in this application, through the series structure of multiple magnetic components 2, the parallel connection of the coils of electromagnets 20, the integrated design of push rod 1, and the modular design of electromagnets 20, achieves the same thrust and stroke while reducing the power of a single electromagnet 20 in the drive assembly, effectively solving the problem of severe heat dissipation of electromagnets 20, thus making it compatible with more models.

[0146] Among them, such as Figures 3 to 6 As shown, the electromagnetic push rod 1 is made into a single unit, with the entire coil voltage connected in parallel. Even if the resistance values ​​of the electromagnets 20 are different or there are assembly errors, the synchronization of the push rod 1 will not be affected, nor will the superposition of the effects be affected. The mounting part 22 includes a steel plate, and the use of steel plates for connection ensures the strength of the drive assembly and prevents deformation of the drive assembly. At the same time, the distance between the electromagnets 20 is designed to be large enough to effectively prevent magnetic leakage and magnetic short circuits.
