DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples.

[0039] In the prior art, some refrigerators are provided with drawers at the bottom of the cabinet, and items in the lower space of the cabinet can be conveniently accessed by pulling out the drawers. However, if heavy frozen items are placed in the drawers, when the drawers are fully pulled out, the drawers may tip forward due to the shift of their center of gravity, causing injuries to the user.

[0040] In order to solve the technical problem that the center of gravity of existing drawers is easily shifted and tipped over when pulled out, causing injuries to users, the present application provides a drawer and a refrigerator using the same, which can provide stable supporting force when the drawer is fully pulled out to prevent the center of gravity of the drawer from shifting and tipping forward, thereby ensuring the safety of the user.

[0041] Figures 1 to 3 A drawer 1 provided in an embodiment of the present application includes a slide rail 11, a bracket 12, a door body 14 and a support assembly 15. The bracket 12 is slidably arranged on the slide rail 11, and a drawer bucket 13 is arranged on the bracket 12; the door body 14 is arranged on the bracket 12, and a first accommodating cavity (not shown in the figure) is arranged on the door body 14; the support assembly 15 is embedded in the first accommodating cavity of the door body 14, and the support assembly 15 includes an installation box 151, a transmission device and a lifting leg 152, and the installation box 151 is fixed to the door body 14 The transmission device and the lifting leg 152 are connected, and the power output end of the transmission device is connected to the lifting leg 152 so that the lifting leg 152 can reciprocate relative to the mounting box 151; wherein the bracket 12 has a first position and a second position, and in the first position, the lifting leg 152 is accommodated in the mounting box 151; in the second position, one end of the lifting leg 152 passes through the mounting box 151 and the door body 14 in sequence and abuts against the supporting surface to support the drawer 13.

[0042] For the sake of ease of explanation and understanding, the side of the drawer 1 facing the user is referred to as the "front", and the side away from the user is referred to as the "rear". It can be understood that initially, the bracket 12 is located in the first position, that is, the bracket 12 is received in the first accommodating cavity, and at this time, the lifting leg 152 is completely received in the installation box 151. When an external force acts on the door body 14, the bracket 12 slides forward with the drawer 13 relative to the slide rail 11, and the lifting leg 152 moves downward relative to the installation box 151 until the bracket 12 reaches the second position (dead point position). At this time, one end of the lifting leg 152 passes through the installation box 151 and the door body 14 in turn and abuts against the supporting surface (such as the ground), thereby providing a stable supporting force to the door body 14. Since the door body 14 and the bracket 12 are connected, the lifting leg 152 can provide a stable supporting force to the drawer 13 to prevent the center of gravity from shifting and tipping forward, thereby ensuring the safety of the user.

[0043] It is worth mentioning that the user can also manually switch the bracket 12 from the second position to the first position so that the lifting legs 152 are restored to the initial state of being completely stored in the installation box 151, which is not limited here.

[0044] In some embodiments, Figures 4 to 6As shown, the transmission device includes a roller 153, a main shaft 154 and a first coil spring 155. The roller 153 is rotatably arranged in the installation box 151, and the main shaft 154 is partially embedded in the roller 153. The main shaft 154 and the lifting legs 152 are staggered. The first coil spring 155 is wound around the circumference of the main shaft 154, one end of the first coil spring 155 is clamped and connected to the roller 153, and the other end is clamped and connected to the main shaft 154. A transmission member is arranged between the main shaft 154 and the lifting legs 152, and the transmission member is arranged at one end of the main shaft 154 away from the first coil spring 155, so that the lifting legs 152 can rotate while sliding relative to the installation box 151.

[0045] When the bracket 12 switches from the first position to the second position, the roller 153 rotates relative to the installation box 151. Since the first coil spring 155 and the roller 153 are clamped and connected, the first coil spring 155 transmits the torque to the main shaft 154 after being stressed, driving the main shaft 154 to rotate relative to the installation box 151. Under the transmission action of the transmission member, the torque of the main shaft 154 is transmitted to the lifting leg 152, so that the lifting leg 152 can rotate and slide relative to the installation box 151 until one end of the lifting leg 152 abuts against the support surface.

[0046] In some embodiments, Figure 4 As shown, the transmission member includes a worm 1543 and a gear 156 meshingly connected to the worm 1543, the main shaft 154 and the worm 1543 are coaxially arranged and fixedly connected, the gear 156 is rotatably arranged in the installation box 151, the axial direction of the gear 156 is provided with a limited structure, the gear 156 is sleeved on the circumference of the lifting leg 152 and a mutually matching thread is arranged between the two. Through the transmission action of the worm 1543 and the gear 156, the gear 156 is forced to rotate, and because the axial direction of the gear 156 has been limited, under the threaded transmission action of the gear 156 and the lifting leg 152, the lifting leg 152 slowly descends or slowly rises.

[0047] Furthermore, if Figure 4 As shown, the roller 153 has a first opening 1531, and the main shaft 154 is provided with a cover 1541, which covers the first opening 1531 of the roller 153, and the first coil spring 155 is received in the receiving space formed by the roller 153 and the cover 1541; one end of the main shaft 154 away from the transmission member extends into the first opening 1531 and is provided with a first slot 1542 ( Figure 6), one end of the first coil spring 155 is connected to the first clamping groove 1542 by clamping, and the inner side wall of the roller 153 is provided with a clamping rib 1533, and the other end of the first coil spring 155 is connected to the clamping rib 1533 by clamping. The storage space formed by the cover 1541 and the roller 153 can limit the side of the first coil spring 155 to prevent the first coil spring 155 from axial displacement and movement, thereby ensuring the smooth sliding of the lifting leg 152.

[0048] In some embodiments, Figures 4 to 6 As shown, the outer wall of the drum 153 is provided with a wire-receiving groove 1532, and a second coil spring 157 is wound on the wire-receiving groove 1532; the installation box 151 is provided with a second opening 1513, one end of the second coil spring 157 is fixedly connected to the outer wall of the drum 153, and the other end passes through the second opening 1513 and is fixedly connected to the external device. The second coil spring 157 is initially in a relaxed state. When the user pulls the door body 14 to make the bracket 12 slide forward, the second coil spring 157 is slowly pulled out, so that the drum 153 rotates relative to the installation box 151 until the bracket 12 reaches the second position (dead point position), and the lifting leg 152 slowly descends relative to the installation box 151. During this process, the second coil spring 157 stores elastic potential energy; when the bracket 12 is forced to leave the second position, under the action of the elastic restoring force of the second coil spring 157, the drum 153 rewinds the second coil spring 157 in the wire-receiving groove 1532, and the lifting leg 152 slowly rises and resets relative to the installation box 151.

[0049] Furthermore, if Figure 2 As shown, the bracket 12 is provided with a slide plate 121 that is slidably connected to the slide rail 11, and the end of the slide rail 11 facing the door body 14 is provided with a limit groove 111 that can be clamped and connected to the slide plate 121. By providing the limit groove 111, the end of the slide rail 11 facing the user is lower than the other end of the slide rail 11 in the horizontal direction. When the bracket 12 moves forward along the slide rail 11 to the limit groove 111, the drawer 13 as a whole is deflected downward by gravity, and the bracket 12 is clamped at the position of the limit groove 111, which is the dead point position, so that the drawer 13 is fixed as a whole, thereby realizing the self-locking of the drawer 13. When the drawer 13 is to be restored, the user manually lifts the drawer 13 and pushes it back slightly to disengage the drawer 13 from the dead point position.

[0050] In some embodiments, Figure 5 and Figure 6 As shown, a first sleeve 1544 is provided on the main shaft 154, a first convex rib 1514 is provided on the inner side wall of the mounting box 151, and the end surface of the first sleeve 1544 abuts against the first convex rib 1514 to achieve axial positioning of the main shaft 154. The first sleeve 1544 limits the degree of freedom of the main shaft 154, so as to prevent the main shaft 154 from generating radial vibration during the rotation process.

[0051] In some embodiments, Figure 5 and Figure 7 As shown, a second sleeve 1561 is provided on the axle of the gear 156, a second rib 1515 is provided on the inner side wall of the mounting box 151, and the end surface of the second sleeve 1561 abuts against the second rib 1515 to achieve axial limiting of the gear 156. The second sleeve 1561 can not only limit the axial displacement of the axle of the gear 156, but also prevent the gear 156 from generating radial vibration during the rotation process.

[0052] In some embodiments, Figure 3 As shown, the installation box 151 includes a transverse box body 1511 and two longitudinal box bodies 1512, and the two longitudinal box bodies 1512 are respectively arranged at both ends of the transverse box body 1511; two lifting legs 152 are provided, and the two lifting legs 152 correspond to the longitudinal box bodies 1512 one by one, and the lifting legs 152 are slidably arranged in the longitudinal box bodies 1512; two main shafts 154 are provided, and the roller 153 and the two main shafts 154 are all arranged in the transverse box body 1511. Through the above arrangement, the stability of the lifting legs 152 supporting the drawer 13 can be improved.

[0053] like Figure 8 As shown, the door body 14 includes a door shell 141 and a door lining 142 arranged on the door shell 141. The door lining 142 is sealed around with a seal 143. Usually, the door lining 142 is filled with a foaming liquid to form an insulation layer to achieve heat preservation of the refrigerator. It should be noted that the horizontal box body 1511 and the longitudinal box body 1512 are integrally arranged to form an integral shell. Since the installation box 151 is pre-installed in the door lining 142, this arrangement can prevent the foaming liquid from leaking into the installation box 151 and affecting the normal operation of the lifting legs 152. In order to allow the lifting legs 152 to pass through the door body 14 to provide support, the bottom of the door lining 142 of the door body 14 is also provided with a through groove (not shown in the figure) for the lifting legs 152 to pass through.

[0054] Furthermore, if Figure 4 As shown, two first openings 1531 are provided, and the two first openings 1531 are arranged back to back. The first openings 1531 are symmetrically arranged on both sides of the wire taking-up groove 1532, so as to ensure the uniform force of the first coil spring 155. After the first coil spring 155 is stressed, the torque is transmitted to the main shaft 154, driving the main shaft 154 to rotate relative to the installation box 151, and then driving the lifting legs 152 to descend smoothly.

[0055] In some embodiments, Figure 8As shown, a limit rod 122 is provided at one end of the bracket 12 away from the lifting leg 152, and a second clamping groove connected to the limit rod 122 is provided on the drawer 13. The limit rod 122 and the second clamping groove are clamped to limit the horizontal direction of the drawer 13, thereby preventing the drawer 13 from being disengaged from the bracket 12 backwards during the pulling process.

[0056] In some embodiments, Figure 8 As shown, a mounting plate 123 is provided at one end of the bracket 12 near the lifting leg 152, and the door body 14 is connected to the mounting plate 123 by a fastener. The fastener can be a screw, and the mounting plate 123 is provided to limit the horizontal direction of the drawer 13 by the door body 14, so as to prevent the drawer 13 from detaching forward from the bracket 12 during the drawing process.

[0057] like Fig. 9 and Fig.10 As shown, the embodiment of the present application also provides a refrigerator 100, including a cabinet body 2 and a drawer 1 as described above, wherein the cabinet body 2 is provided with a second accommodating cavity (not shown in the figure); the drawer 1 is embedded in the second accommodating cavity 21, and the slide rail 11 of the drawer 1 is fixedly connected to the cabinet body 2. The working principle and working process of the refrigerator 100 refer to the aforementioned embodiment of the drawer 1, and are not described in detail here. By providing the drawer 1 as described above, the lifting legs 152 can provide a stable supporting force to the drawer 1 during the pulling process, so as to prevent the center of gravity of the refrigerator 100 from moving forward and tipping over.

[0058] It should be noted that one end of the second coil spring 157 away from the roller 153 passes through the second opening 1513 and is fixedly connected to the bottom of the second accommodating cavity to achieve automatic resetting of the lifting leg 152 .

[0059] Optionally, a grille is provided inside the cabinet 2 to divide the internal space of the cabinet 2 into an upper accommodating chamber and a lower accommodating chamber, wherein the lower accommodating chamber is the aforementioned second accommodating chamber. By providing a slidable drawer 13 in the lower accommodating chamber of the cabinet 22, the user pulls the door 14 to slide forward, and the bracket 12 slides the drawer 13 forward, thereby facilitating the access to items stored in the lower accommodating chamber of the refrigerator 100, and at the same time, it can avoid excessive loss of cold caused by opening the door for too long, thereby reducing the risk of frost inside the refrigerator 100.

[0060] In addition, a driving member (such as a cylinder) can be provided on the cabinet 2, and the power output end of the driving member is transmission-connected to the bracket 12, so that the bracket 12 can automatically switch between the first position and the second position under the driving force of the driving member, which is not limited here.

[0061] It should be noted that the drawer 1 provided in the present application is intended for use in the field of refrigeration equipment, and can also be applied to other equipment that requires a drawer 1, such as cabinets in the electrical industry, cabinets and wardrobes in the home improvement industry, etc., which will not be repeated here.
