[0027] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1 and Figure 2 As shown, a refrigeration device according to an embodiment of the present invention comprises a refrigeration box 100 for accommodating food or other items to be refrigerated (or frozen). In the following embodiments, the refrigeration device is a refrigerator.

[0031] The refrigeration box 100 includes a box body 20 and a drawer 40 that is push-pull mounted on the box body 20. When in use, the user pulls out the drawer 40 to place food (or other items) in or take them out of the drawer 40, and then pushes the drawer 40 back into the box body 20 to complete the taking of food (or other items).

[0032] The box body 20 includes a box body 21 and a box push-pull assembly 23. The box body 21 is a cubic shell structure, including a bottom wall, a left side wall, a right side wall, a rear side wall and a top wall, and the bottom wall, the left side wall, the right side wall, the rear side wall and the top wall are all rectangular plate structures. The left side wall and the right side wall are arranged at intervals on both sides of the bottom wall along the length direction of the bottom wall, and extend from the edge of the bottom wall along the thickness direction of the bottom wall toward the same side of the bottom wall; the rear side wall is arranged on one side of the bottom wall in the width direction and connected between the left side wall and the right side wall; the top wall is connected to the left side wall, the right side wall and the side of the top wall away from the bottom wall.

[0033] Thus, the bottom wall, the left side wall, the right side wall and the rear side wall together form a receiving cavity 212 having an open end and a closed end that are arranged opposite to each other, the bottom wall, the left side wall, the right side wall and the end of the top wall away from the rear side wall form an open end, and the bottom wall, the left side wall, the right side wall, the rear side wall and the top wall together form a closed end. It can be understood that the shape of the liner body 21 is not limited to this, and in other embodiments, the liner body 21 can be set to different shapes as needed.

[0034] The two sets of box push-pull assemblies 23 are correspondingly arranged on the left and right walls of the inner tank body 21, and each set of box push-pull assemblies 23 extends from the closed end of the accommodating cavity 212 to the open end of the accommodating cavity 212. The two sets of box push-pull assemblies 23 are used to cooperate with the drawer 40 to support the drawer 40 and guide the drawer 40 to move.

[0035] The drawer 40 includes a drawer body 41 and a drawer push-pull assembly 43 disposed on the drawer body 41. The drawer body 41 includes a drawer bottom wall and a drawer side wall extending in the same direction from the edge of the drawer bottom wall, and the drawer side wall surrounds the outer periphery of the drawer bottom wall to form a drawer storage cavity for accommodating food (or other items) together with the drawer bottom wall. Two groups of drawer push-pull assemblies 43 are symmetrically disposed on the drawer side walls on both sides of the drawer body 41, and each group of drawer push-pull assemblies 43 can respectively cooperate with a group of box push-pull assemblies 23 and slide along the box push-pull assemblies 23 in a controlled manner, so that the drawer body 41 moves between an extended position extending out of the accommodating cavity 212 and a retracted position stored in the accommodating cavity 212.

[0036] Among them, the box push-pull assembly 23 and / or the drawer push-pull assembly 43 include a rolling member with an outer cylindrical surface, and the box push-pull assembly 23 and / or the drawer push-pull assembly 43 have an arc-shaped stop surface. When the drawer body 41 is in the retracted position, the outer cylindrical surface of the rolling member contacts the arc-shaped stop surface to block the rolling member. In this way, the arc-shaped stop surface and the outer cylindrical surface of the rolling member have a large contact area, so that the impact force of the drawer push-pull assembly 43 on the box push-pull assembly 23 can be alleviated when the drawer body 41 returns to the retracted position from the extended position, so that the drawer body 41 can be braked smoothly, reducing the impact noise, thereby effectively improving the user experience.

[0037] Specifically, the shape of the arcuate stop surface matches the shape of the outer cylindrical surface of the rolling element, and the radius of the arcuate stop surface is 0.5mm-1mm larger than the radius of the outer cylindrical surface of the rolling element, thereby having a larger contact area and effectively alleviating the impact while avoiding the rolling element from getting stuck.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the box push-pull assembly 23 includes a box slide rail 22 in the shape of a long strip, and the box slide rail 22 extends from the closed end of the accommodating cavity to the open end. The box slide rail 22 is provided with a box slide groove 221 extending from the closed end of the accommodating cavity 212 to the open end of the accommodating cavity 212, and one end of the box slide groove 221 close to the closed end of the accommodating cavity 212 forms a box arc-shaped stop surface 2212a, and one end of the box slide groove 221 close to the open end of the accommodating cavity 212 is connected to the end wall of the box slide rail 22 facing the open end.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, the drawer push-pull assembly 43 includes a drawer rail 432 and a drawer rolling member 434. The shape of the drawer rail 432 matches the shape of the box slide groove 221 of the box slide rail 22, and the drawer rolling member 434 is arranged at one end of the drawer rail 432. In this way, the drawer push-pull assembly 43 extends into the box slide groove 221 from one end of the box slide groove 221 close to the opening end of the accommodating cavity 212. When the drawer body 41 is in a push-pull state, the drawer rolling member 434 rolls along the box slide groove 221 to improve the smoothness of the push-pull process. When the drawer body 41 is in the retracted position, the outer cylindrical surface of the drawer rolling member 434 contacts the arc-shaped stop surface 2212a of the box to disperse the impact force.

[0040] like Figure 4 As shown, in some embodiments, one end of the drawer rail 432 away from the drawer rolling member 434 is bent to one side to form a drawer arc stop surface 4321, and the box push-pull assembly 23 includes a box rolling member 24, and the box rolling member 24 is located at one end of the box rail 22 close to the opening end of the accommodating cavity. In this way, when the drawer body 41 is in a push-pull state, the box rolling member 24 and the drawer rail 432 are separated from each other. When the drawer 40 is in the retracted position, the outer circumferential surface of the box rolling member 24 contacts the drawer arc stop surface 4321 to disperse the impact force.

[0041] Further, in some embodiments, the box slide 221 includes a first sliding section 2212 near the closed end of the accommodating cavity 212 and a second sliding section 2214 near the open end of the accommodating cavity 212, the first sliding section 2212 bends and extends from one side of the second sliding section 2214 in the direction of gravity, the arc stop surface is located at the first sliding section 2212, and the height of the first sliding section 2212 in the direction of gravity is less than the height of the second sliding section 2214 in the direction. Correspondingly, the shape of the drawer slide 432 also matches the shape of the box slide 221. In this way, there is a certain height difference between the first sliding section 2212 and the second sliding section 2214, so that the drawer 40 forms a gravity self-locking, which effectively prevents the drawer body 41 from sliding out of the accommodating cavity 212 when the refrigeration box 100 tilts forward slightly or when the box push-pull assembly 23 and the drawer push-pull assembly 43 collide with each other.

[0042] Specifically, in some embodiments, the maximum height difference between the first sliding section 2212 and the second sliding section 2214 is 8 mm-10 mm, thereby achieving the gravity self-locking requirement while ensuring a good push-pull feel and further improving the user experience.

[0043] See also Figure 5In some embodiments, the drawer rolling member 434 includes a drawer rolling member body 4341 and a drawer rolling member body buffer ring 4343 that can generate restorable deformation. The drawer rolling member body 4341 is provided with a limiting groove along the circumferential direction. The drawer rolling member body buffer ring 4343 is partially limited in the limiting groove so as to surround the drawer rolling member body 4341. The drawer rolling member body buffer ring 4343 forms an outer circular surface in contact with the drawer arc stop surface 4321. In this way, the drawer rolling member body buffer ring 4343 can play a buffering role, further buffering the impact force of the drawer rolling member 434 on the drawer arc stop surface 4321.

[0044] The box rolling element 24 includes a box rolling element body and a box rolling element buffer ring that can generate restorable deformation. The box rolling element body is provided with a limiting groove along the circumferential direction. The box rolling element buffer ring is partially limited in the limiting groove so as to surround the box rolling element body. The box rolling element buffer ring forms an outer circumferential surface in contact with the box arc-shaped stop surface 2212a. In this way, the box rolling element buffer ring can play a buffering role, further buffering the impact force of the box rolling element 24 acting on the box arc-shaped stop surface 2212a.

[0045] The above-mentioned refrigeration box 100 and refrigeration equipment, because the collision surface of the box push-pull assembly 23 and the drawer push-pull assembly 43 is an arc surface, has a large buffer area, can effectively disperse the impact force, and at the same time limit the impact bounce and impact rebound of the rolling element. In addition, because the front and rear of the box slide groove 221 of the box push-pull assembly 23 have a certain height difference, the gravity self-locking effect can be effectively utilized to effectively prevent the drawer body 41 from sliding out of the accommodating cavity when the refrigeration box 100 is slightly tilted forward or when the box push-pull assembly 23 and the drawer push-pull assembly 43 collide with each other.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
