[0002] Storage devices are commonly used household appliances in daily life. Take the refrigerator as an example. Due to the pressure difference between the inside and outside of the refrigerator and the suction of the refrigerator door seal, it is quite difficult to open the refrigerator.

[0048] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.
[0049] Reference below Figures 1-6 The power-assisting handle 100 and the storage device according to the embodiment of the present application are described.
[0050] It should be noted that the storage equipment in this embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, cold storage cabinets and refrigerated vending machines and other refrigeration storage equipment. The storage equipment has diverse structural forms and a wide range of applications.
[0051] Reference Figures 1 to 3 The power-assisting handle 100 includes an embedded box 110, a push rod 120, a handle 130 and a transmission assembly.
[0052] The embedded box 110 is used to be embedded in the front surface of the door body 200 of the storage device, so that the surface of the door body 200 of the storage device looks neater, without unnecessary protrusions or external devices. This embedded design can be perfectly integrated with the door body 200, improving the overall aesthetics. By embedding the embedded box 110 into the front surface of the door body 200, the operating space required for opening and closing the door of the storage device can be reduced to a certain extent. The embedded box 110 can be pre-installed when the storage device is manufactured, making the subsequent installation process easier. At the same time, because it is embedded, no additional brackets or fixing devices are required, reducing the complexity and cost of installation. Since the embedded box 110 is embedded inside the door body 200, it can provide better protection from external damage or accidental touch.
[0053] It should be noted that the embedded box 110 has various shapes, see Figure 4 In the embodiment of the present application, the embedded box 110 is a cube. Of course, in other embodiments, the embedded box 110 can also be cylindrical or rectangular, etc. Specifically, the present application does not limit this.
[0054] The push rod 120 is movably mounted within the embedded box 110 in a forward-backward direction, allowing one end of the push rod 120 to pass through the rear surface of the door 200 and abut against the storage device housing. This flexible mounting of the push rod 120 within the embedded box 110 achieves seamless integration between the push rod 120 and the storage device. This design eliminates the need for the push rod 120 to be attached to the door 200 as a separate component, thereby enhancing the overall neatness and aesthetics. The movable mounting of the push rod 120 allows the user to conveniently control the power-assisted opening of the storage device by actuating the push rod 120. One end of the push rod 120 can pass through the rear surface of the door 200 and abut against the housing, effectively pushing the housing. This design makes operation more intuitive and simple. The push rod 120 is mounted within the embedded box 110, providing stable support and positioning. This mounting method reduces the potential for wobble or misalignment of the push rod 120 during use, thereby enhancing its stability and reliability. The design of the embedded box 110 can provide a certain degree of protection for the push rod 120 . In addition, the design of the embedded box 110 also improves the convenience of maintenance and care.
[0055] The handle 130 is movably mounted within the embedded box 110, such that it has a first position in which it is located within the embedded box 110 and a second position in which it is at least partially located outside the embedded box 110. When in the second position, the handle 130 is adapted to rotate relative to the embedded box 110 about a first axis. Thus, when the handle 130 is in the first position, it is completely located within the embedded box 110 and does not occupy space outside the storage device door 200, thereby maximizing space utilization. This design also ensures the neatness and aesthetics of the door 200, preventing it from protruding from the exterior surface of the storage device door 200 and disrupting the design lines of the storage device. When in the first position, the handle 130 is concealed within the embedded box 110, reducing the possibility of accidental collisions or scratches. Furthermore, because the handle 130 is movably mounted, it provides a certain degree of cushioning against external forces, further enhancing user safety. When the handle 130 is adjusted to the second position, at least partially extending outside the embedded box 110, the user can easily grasp and operate the handle 130. This greatly improves ease of use. When the handle 130 is in the second position, it can rotate about the first axis relative to the embedded box 110, providing the user with more operational options. The user can adjust the angle and position of the handle 130 as needed to suit different usage scenarios and habits.
[0056] The transmission mechanism connects the handle 130 and the push rod 120 to convert rotation of the handle 130 into movement of the push rod 120. Thus, when a user turns the handle 130, the rotation is efficiently converted into movement of the push rod 120, enabling the push rod 120 to rotate the door 200 of the storage device relative to the housing, achieving power-assisted opening of the door 200. The transmission mechanism typically amplifies or converts torque, allowing the user to turn the handle 130 with minimal force while still providing the push rod 120 with sufficient force to open the storage device. This not only reduces the user's operational burden but also improves operational convenience. The transmission connection design allows the handle 130 and push rod 120 to connect and mate within the embedded box 110, eliminating the need to occupy excessive space outside the door 200. This compact design optimizes the overall structure of the storage device, making the door 200 more neat and aesthetically pleasing. The transmission mechanism typically utilizes precision-engineered and manufactured components, ensuring excellent reliability and stability. This design can ensure that the rotation of the handle 130 can be accurately converted into the movement of the push rod 120, avoiding operational failures caused by looseness, wear or misalignment.
[0057] According to the storage device of the present application, the design of the power-assisting handle 100 embeds the embedded box 110 in the front surface of the door body 200 of the storage device, thereby optimizing the use of space. At the same time, because the handle 130 and the push rod 120 are both hidden in the embedded box 110, the door body 200 has a neat appearance and no protruding parts, which improves the aesthetics of the storage device. The handle 130 is embedded in the front surface of the door body 200, so that when the storage device is installed in an embedded manner, the power-assisting handle 100 will not interfere with foreign objects around the storage device, allowing the power-assisting handle 100 to smoothly assist in opening the door. This not only reduces the user's operating burden, but also improves the convenience of operation.
[0058] Reference Figure 4 and Figure 5In one embodiment, the push rod 120 is provided with a rack 121 extending in the front-to-back direction. The transmission assembly includes a driving bevel gear 141, a driven bevel gear 142, and a cylindrical gear 143. The driving bevel gear 141 is connected to the handle 130 and is adapted to rotate about the first axis. The driven bevel gear 142 is mounted in the embedded box 110 and is adapted to rotate about a second axis. The second axis is perpendicular to the front-to-back direction. The driven bevel gear 142 meshes with the driving bevel gear 141. The cylindrical gear 143 is connected to the driven bevel gear and adapted to rotate about the second axis. The cylindrical gear 143 meshes with the rack 121. In this way, the rotation of the handle 130 can be efficiently and accurately converted into the forward and backward movement of the push rod 120. This design ensures the continuity and stability of power transmission and improves transmission efficiency. By meshing the driving bevel gear 141 and the driven bevel gear 142, this design allows the transmission assembly to be arranged in a more compact manner within the embedded box 110, thereby optimizing space utilization. This design also optimizes the transmission ratio and load-bearing capacity, allowing it to withstand larger torques and loads, thereby improving the stability and reliability of the power-assisted handle 100. The user simply turns the handle 130 to activate the push rod 120 through the transmission assembly. This design makes operation more intuitive and convenient, reducing the difficulty of use. Because the various components of the transmission assembly are movably mounted, they can be easily disassembled and reinstalled when repair or replacement is required. In addition, the gear transmission structure is relatively simple, making it easier to maintain.
[0059] Reference Figure 5, in one embodiment, the base circle diameter of the driven bevel gear 142 is D1, and the base circle diameter of the cylindrical gear 143 is D2, where D2 < D1. In this way, it can be realized that the driven bevel gear 142 and the cylindrical gear 143 are coaxially arranged and fixedly connected, which ensures that the transmission relationship between them is more stable and reliable. This design makes the layout of the driven bevel gear 142 and the cylindrical gear 143 in the embedded box 110 more compact. This compactness not only optimizes the space utilization but also makes the entire transmission component more stable and less affected by external factors. With the setting of D2 < D1, this design can increase the transmission ratio. This means that when the handle 130 rotates, the force transmitted to the push rod 120 through the transmission component will be amplified, thus realizing the enhancement of the force for the movement of the push rod 120. After the transmission force is amplified, the push rod 120 can obtain a greater force when moving, enabling it to more easily overcome the resistance of the storage device door body 200 to open. In this way, the user experience can be significantly improved. Due to the amplification of the transmission force, the user does not need to apply too much force when operating the handle 130 to realize the movement of the push rod 120. This makes the operation easier and more convenient, reducing the user's operation difficulty. The amplification of the transmission force means that the push rod 120 can respond to the rotation of the handle 130 with higher efficiency, reducing the energy loss during the transmission process. This helps to improve the overall performance of the storage device, making it more efficient and faster to complete the opening action.
[0060] In addition, since the driven bevel gear 142 and the cylindrical gear 143 are fixedly connected, they can be treated as a whole during maintenance and replacement, simplifying the maintenance process. In addition, the coaxial arrangement reduces the number of components in the transmission component, further reducing the complexity of maintenance. The cylindrical gear 143 with a smaller base circle diameter may involve less material and a simpler processing technology during manufacturing, which helps to reduce the production cost.
[0061] It should be noted that since the base circle diameter D1 of the driven bevel gear 142 is greater than the base circle diameter D2 of the cylindrical gear 143, it can be realized that the number of teeth of the driven bevel gear 142 is greater than the number of teeth of the cylindrical gear 143. In this way, the amplification of the transmission force of the transmission component can be realized. In addition, in the embodiments of the present application, the pitch of the cylindrical gear 143 is the same as the pitch of the driven bevel gear 142. Of course, in other embodiments, the pitch of the cylindrical gear 143 can be different from the pitch of the driven bevel gear 142. Specifically, the present application does not limit this.
[0062] In one embodiment, the number of teeth of the driving bevel gear 141 is Z1, and the number of teeth of the driven bevel gear 142 is Z2, where Z1 < Z2. Due to the fact that the number of teeth Z1 of the driving bevel gear 141 is less than the number of teeth Z2 of the driven bevel gear 142, according to the principle of gear transmission, this design can increase the transmission ratio. The increase in the transmission ratio means that when the driving bevel gear 141 rotates, the driven bevel gear 142 will transmit a larger torque at a smaller rotational speed to the subsequent transmission components, thereby enhancing the force for the movement of the push rod 120. By making Z1 less than Z2, the small rotation of the driving bevel gear 141 can be converted into a large torque output of the driven bevel gear 142, thus more effectively transmitting the force applied by the user on the handle 130 to the push rod 120 and achieving a more efficient force transmission. Due to the increase in the transmission ratio, the user only needs to apply a smaller force when operating the handle 130 to achieve a larger movement of the push rod 120. This not only reduces the operation difficulty for the user but also improves the operation efficiency, making the process of opening the door body 200 of the storage device easier and faster.
[0063] Specifically, in the embodiment of the present application, Z1 / Z2 = 1 / 2. In this way, the transmission ratio can be precisely controlled. In this design, the transmission ratio is 1:2, which means that when the driving bevel gear 141 rotates one full circle, the driven bevel gear 142 will rotate half a circle. This precise control of the transmission ratio helps to achieve precise control of the movement of the push rod 120, ensuring that the rotation of the handle 130 can be accurately converted into the movement of the push rod 120. The design with a transmission ratio of 1:2 enables the driven bevel gear 142 to transmit a larger torque when rotating. This means that the force applied by the user through the handle 130 can be transmitted to the push rod 120 with higher efficiency after passing through the transmission components, thereby more effectively driving the opening of the door body 200 of the storage device. Due to the optimization of the transmission ratio, the user only needs to apply a smaller force when operating the handle 130 to achieve a larger movement of the push rod 120. This reduces the operation difficulty, enabling the user to more easily control the opening or closing process of the storage device. The precise design of the transmission ratio helps to reduce friction and wear in the transmission components, thereby reducing the maintenance cost and extending the service life of the transmission components.
[0064] It should be noted that in other embodiments, Z1 / Z2 can also be other values. For example, Z1 / Z2 can also be 1 / 3, 1 / ④, 1 / 5 or others. Specifically, the present application does not limit this. The specific value of Z1 / Z2 can be set according to needs.
[0065] Refer to Figures 4 to 6 It should be noted that in the above translation, "④" in the original text is likely a misrepresentation and is translated as "④" here. If this is an incorrect symbol, please correct it in the original text for a more accurate translation.In one embodiment, the transmission assembly further includes a bearing 144. An inner core 1441 of the bearing 144 is connected to the handle 130 and is mounted within the embedded box 110 for rotation about the first axis. An outer ring 1442 of the bearing 144 is connected to the driving bevel gear 141 and adapted to rotate synchronously with the inner core 1441. Connecting the handle 130 and the driving bevel gear 141 via the bearing 144 ensures smooth transmission of the handle 130's rotation to the driving bevel gear 141, reducing friction and vibration that would otherwise be generated by a direct connection, thereby improving the smooth rotation of the entire transmission assembly. Because the use of the bearing 144 reduces the risk of wear and failure, the maintenance frequency and cost of the transmission assembly are also reduced. The low coefficient of rotational friction of the bearing 144 reduces energy loss during transmission and improves transmission efficiency. This helps more effectively transmit the force applied by the user to the handle 130 to the push rod 120, enabling more efficient opening of the door 200 of the storage device.
[0066] Reference Figure 5 In one embodiment, the outer wall surface of the inner core 1441 is provided with a plurality of teeth 1443, and the plurality of teeth 1443 are arranged at intervals along the circumference of the outer ring 1442, and a cylinder 1444 is provided between each adjacent tooth 1443, and the cylinder 1444 is extended along the extension direction of the first axis, and the inner wall surface of the outer ring 1442 is provided with a plurality of grooves (not drawn in the figure), and the plurality of grooves are arranged in a one-to-one correspondence with the plurality of cylinders 1444, and the inner wall surface of each groove is suitable for abutting against the side wall surface of the corresponding cylinder 1444. In this way, when the inner core 1441 is driven to rotate, the inner core 1441 can abut against the inner wall surface of the groove through the outer wall surface of the cylinder 1444, thereby driving the outer ring 1442 to rotate. This design ensures the accuracy and reliability of the transmission and avoids transmission failure caused by dislocation or slippage. Cylinder 1444 abuts the sidewalls of the groove. This design reduces the friction area during rotation, thereby reducing friction and wear. This not only helps extend the service life of bearing 144, but also improves transmission efficiency and reduces energy loss. The design of teeth 1443, cylinder 1444, and grooves facilitates and simplifies the assembly of inner core 1441 and outer ring 1442. The structural design of teeth 1443 and cylinder 1444 enables bearing 144 to maintain stable rotation performance even under heavy loads, improving the applicability and reliability of the transmission assembly.
[0067] Reference Figure 5In one embodiment, two adjacent tooth portions 1443 have a first tooth surface 14431 and a second tooth surface 14432 that are arranged opposite to each other, and the area of the first tooth surface 14431 is larger than the area of the second tooth surface 14432. In this way, since the area of the first tooth surface 14431 is larger than the area of the second tooth surface 14432, this asymmetric tooth surface design can more effectively disperse the load and reduce the stress concentration between the tooth surfaces. This helps to achieve smoother and more uniform force transmission during the transmission process, thereby improving transmission efficiency. A large tooth surface area means a larger contact area. This design can better withstand the force and torque generated by heavy loads or high-speed rotation, thereby improving the durability and reliability of the bearing 144.
[0068] It should be noted that in the embodiment of the present application, the push rod 120 can be moved by rotating the handle 130 clockwise to realize the power-assisted opening of the storage device light strip door 200. Then the first tooth surface 14431 is in front of the second tooth surface 14432. In this way, when the handle 130 is rotated clockwise, the first tooth surface 14431 will first abut against the cylinder 1444 and transmit force to drive the outer ring 1442 to rotate. Since the area of the first tooth surface 14431 is large, it can more effectively disperse the load and transmit torque, thereby improving the efficiency of the transmission. The large area of the first tooth surface 14431 not only provides stronger transmission capacity, but also enhances the stability of the structure. This helps to reduce the vibration and noise caused by force transmission and improve the stability and reliability of the entire transmission assembly.
[0069] To reset push rod 120, inner core 1441 is rotated counterclockwise. This causes second tooth surface 14432 to abut against cylindrical body 1444. Specifically, cylindrical body 1444 first abuts against the smaller second tooth surface 14432. The smaller area of second tooth surface 14432 provides a buffering effect for the transmission assembly, reducing the impact and damage to tooth portion 1443 and the entire transmission system caused by sudden reverse rotation or overload. This design helps protect the transmission assembly and extend its service life.
[0070] Reference Figure 4 In one embodiment, the handle 130 is rotatably connected to the inner core 1441 about a third axis, and the direction of the third axis is perpendicular to the front-to-back direction. In this way, since the handle 130 is rotatably connected to the inner core 1441 about the third axis perpendicular to the front-to-back direction, this design allows the user to operate the handle 130 to switch between the first position and the second position, so that the handle 130 is hidden in the embedded box 110 or at least partially exposed outside the embedded box 110, and the operation is simple, thereby improving the convenience of operation.
[0071] It should be noted that there are many ways to switch the handle 130 between the first position and the second position. For example, in one embodiment, the handle 130 can also be slidably installed on the core body along the front-rear direction. In other embodiments, the inner core 1441 can also be slidably installed on the embedded box 110 along the front-rear direction. Specifically, this application does not limit this.
[0072] In addition, the reciprocating motion of the handle 130 between the first position and the second position can be achieved through manual drive, electric drive, or a combination of manual and electric drive. Specifically, this application does not limit this.
[0073] Reference Figure 6 In one embodiment, the power-assisting handle 100 further includes an elastic reset member 150, which is elastically connected to the embedded box 110 and the transmission assembly and is used to drive the transmission assembly to move in the direction of resetting the push rod 120. In this way, the elastic reset member 150 can automatically restore the transmission assembly and the push rod 120 to their initial positions after the user releases the handle 130. This automatic reset function not only facilitates user use, but also avoids the problem of the storage device door 200 not being able to close correctly due to forgetting to reset. With the elastic reset member 150, the user only needs to perform a simple rotation action to achieve the power-assisted opening of the door 200 of the storage device without having to pay extra attention to the reset operation. This greatly reduces the complexity of the operation and improves the convenience of use. Since the elastic reset member 150 uses its own elastic potential energy to achieve the reset function, it does not require the consumption of additional electricity or other energy, and is therefore energy-saving.
[0074] It should be noted that in the embodiment of the present application, the elastic return member 150 includes a torsion spring, one end of which is connected to the embedded box 110 and the other end is connected to the inner core 1441. As such, the torsion spring has unique torsional characteristics, capable of providing a smooth and constant return torque to the inner core 1441. When the user releases the handle 130, the torsion spring can use its torsional force to restore the inner core 1441 to its initial position, thereby driving the push rod 120 to reset. This reset method is both stable and reliable, ensuring the correct closure of the storage device door 200. Because the torsion spring achieves its reset function through torsion, it can adapt to operations at different angles. Regardless of the angle from which the user rotates the handle 130, the torsion spring can effectively provide a return torque, allowing the push rod 120 to reset smoothly. This adaptability makes the design more flexible and versatile, meeting the needs of different usage scenarios.
[0075] Of course, in other embodiments, the elastic return element 150 may also include a tension spring, located between the rack 121 and the embedded box 110 and extending in the front-to-back direction. One end of the spring is connected to the rack 121, and the other end is connected to the embedded box 110. In this way, the spring, due to its elastic properties, can provide a stable return force for the rack 121. When the user releases the handle 130, the elastic force provided by the spring quickly and effectively returns the rack 121 to its initial position, ensuring that the transmission assembly and push rod 120 are properly reset, allowing the storage device door 200 to close smoothly. The provision of the spring enables the rack 121 to respond quickly to external forces and effectively transmit force through the transmission assembly. This fast and accurate transmission response helps improve the transmission efficiency of the entire system, providing users with a smoother and more fluid experience during operation. By directly connecting the spring between the rack 121 and the embedded box 110, the structural design of the transmission assembly can be simplified. This simple design not only reduces manufacturing costs, but also improves system reliability and reduces the potential for malfunctions and maintenance issues caused by complex structures. As a common elastic element, the spring has excellent durability and stability. The spring is placed between the rack 121 and the embedded box 110 to ensure the long-term effectiveness of the reset function and increase the service life of the entire system.
[0076] In a second aspect, the present application further provides a storage device, comprising the power-assisting handle 100 as described above.
[0077] According to the storage device of the present application, the design of the power-assisting handle 100 embeds the embedded box 110 in the front surface of the door body 200 of the storage device, thereby optimizing the use of space. At the same time, because the handle 130 and the push rod 120 are both hidden in the embedded box 110, the door body 200 has a neat appearance and no protruding parts, which improves the aesthetics of the storage device. The handle 130 is embedded in the front surface of the door body 200, so that when the storage device is installed in an embedded manner, the power-assisting handle 100 will not interfere with foreign objects around the storage device, allowing the power-assisting handle 100 to smoothly assist in opening the door. This not only reduces the user's operating burden, but also improves the convenience of operation.
