Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle-mounted refrigerators, in particular to a damping buffer structure and a vehicle-mounted refrigerator. BACKGROUND

[0002] A vehicle-mounted refrigerator is a vehicle-mounted refrigeration or cold storage device. The refrigerator doors of the vehicle-mounted refrigerators on the market are of a flip-open structure. However, the space in a vehicle is limited, especially for compact cars and compact SUVs.

[0003] Among them, the refrigerator door is most commonly used in the use process of the vehicle-mounted refrigerator. The existing refrigerator door is directly connected with the refrigerator through a rotating shaft. However, such a structure will cause a large impact force on the rotating shaft when the refrigerator door is put down, which will easily damage the rotating shaft and generate a relatively large abnormal noise, affecting the use.

[0004] At present, a damping device is usually arranged between the door body and the box body of the existing vehicle-mounted refrigerator to improve the actual use effect of the refrigerator door. Among them, the commonly used damping buffer damping structures of the door body include rotating shaft dampers, gear dampers, spring tension, etc. However, the installation structure is relatively complex, and the damping effect is poor. SUMMARY

[0005] In view of the above shortcomings of the prior art, the purpose of the present application is to disclose a damping buffer structure and a vehicle-mounted refrigerator to improve the poor damping effect of the door body of the existing vehicle-mounted refrigerator during the actual opening and closing process, and to adjust the damping according to the opening angle of the door body.

[0006] To achieve the above-mentioned purpose and other related purposes, the present application discloses a damping buffer structure, which comprises:

[0007] A connecting rod rotates around a center axis, and the connecting rod comprises at least one limiting surface;

[0008] Among them, the limiting surface comprises an initial end and a terminal end, and the connecting surface between the initial end and the terminal end is a continuous arc surface; and in the direction from the initial end to the terminal end, the distance between the arc surface and the axis of the center axis is gradually changed; and

[0009] A limiting member is located on one side of the connecting rod, and the limiting member and the center axis are relatively fixed.

[0010] Among them, the limiting member applies a force to the connecting rod, and the size of the force increases in the direction from the initial end to the terminal end.

[0011] In an aspect of the present application, the limiting surface comprises two groups, including a first limiting surface and a second limiting surface; and the limiting member comprises two groups, one group of the limiting member acting on the first limiting surface, and the other group of the limiting member acting on the second limiting surface.

[0012] In an aspect of the present application, the limiting member and the center shaft are relatively fixedly arranged.

[0013] In an aspect of the present application, the limiting member is a rubber block, and the rubber block is in sliding connection with the connecting rod, and the rubber block is connected to the limiting surface.

[0014] In an aspect of the present application, the limiting member and the center shaft are relatively fixedly arranged.

[0015] In an aspect of the present application, the limiting member is a rubber block, and the rubber block is in sliding connection with the connecting rod, and the rubber block is connected to the limiting surface.

[0016] The present application also provides a vehicle-mounted refrigerator, which is provided with a box body and a door body, and the door body and the box body are arranged in a openable and closable manner.

[0017] Further comprising:

[0018] The damping buffer structure as claimed in any one of the above aspects;

[0022] In an aspect of the present application, a limiting protrusion is further included, which is fixedly connected with the connecting rod, and the limiting protrusion is located at the end of the connecting rod.

[0023] In summary, the present application discloses a damping buffer structure and a vehicle-mounted refrigerator, wherein the distance between the arc-shaped surface and the center axis is gradually changed, so as to adjust the force applied by the limiting member on the connecting rod. In the direction from the initial end to the end, the force gradually increases, so that the damping between the door body and the box body can be adjusted according to the opening angle of the door body. At the same time, the friction between the limiting member and the connecting rod further realizes the damping effect between the door body and the box body.

The present application can also be implemented or applied through other different specific embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application.

[0034] Please refer to Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc. shown in the drawings of the present specification are only used to cooperate with the content disclosed in the present specification, to be understood and read by those skilled in the art, and do not have technical substantive significance, and any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0035] Referring to Figure 1 As shown in the drawings, the present application discloses a damping buffer structure and a vehicle-mounted refrigerator, which can be used to improve the poor damping effect of the door body 100 of the existing vehicle-mounted refrigerator during actual opening and closing, and the difficulty in damping adjustment according to the opening angle of the door body 100. The vehicle-mounted refrigerator is usually provided with a door body 100 and a box body 200, and the door body 100 is a hingeable connection on the box body 200. In an embodiment, the vehicle-mounted refrigerator is provided with a damping buffer structure 300, and the damping buffer structure 300 is located between the door body 100 and the box body 200. Therefore, the damping setting between the door body 100 and the box body 200 can be realized through the damping buffer structure 300.

[0036] Referring to Figure 1 and Figure 2 As shown in the drawings, in an embodiment, the damping buffer structure 300 can include a connecting rod 310 and a limiting piece 320. The connecting rod 310 rotates around a center axis 340, and the limiting piece 320 is used on the connecting rod 310.

[0037] It can be understood that the center axis 340 is located on the box body 200. The door body 100 and the box body 200 are hingeably connected, so the center axis 340 is coincidentally arranged with the hinge center of the door body 100. One end of the connecting rod 310 is fixedly connected with the door body 100, and the other end is slidingly arranged on the box body 200. The limiting piece 320 is located on the box body 200, and the limiting piece 320 and the center axis 340 can be relatively fixedly arranged. At the same time, the limiting piece 320 acts on the connecting rod 310, and through the interaction between the limiting piece 320 and the connecting rod 310, the damping setting between the door body 100 and the box body 200 is realized.

[0038] Specifically, the connecting rod 310 includes at least one limiting surface, and the limiting piece 320 acts on the limiting surface. The limiting surface includes an initial end 3110 and a terminal end 3112, and the initial end 3110 and the terminal end 3112 are connected by a continuous arc surface 3111. The initial end 3110 and the terminal end 3112 are connected to facilitate the relative movement of the limiting piece 320 relative to the arc surface 3111. It should be noted that the distance between the arc surface 3111 and the axis of the center axis 340 is gradually changed to adjust the force exerted by the limiting piece 320 on the connecting rod 310. In the direction from the initial end 3110 to the terminal end 3112, the size of the force increases in turn. In turn, the damping between the door body 100 and the box body 200 can be adjusted according to the opening angle of the door body 100.

[0039] Referring to Fig Figure 3As shown, in an embodiment, the limiting surface of the connecting rod 310 is provided with two groups, including the first limiting surface 301 and the second limiting surface 302. At the same time, the limiting piece 320 includes two groups, one group of limiting pieces 320 is acting on the first limiting surface 301, and the other group of limiting pieces 320 is acting on the second limiting surface 302. Therefore, by providing multiple groups of limiting surfaces, the damping effect of the damping and buffering structure 300 during actual use can be effectively improved to ensure the stability of the damping.

[0040] As shown in the Figures 1 to 3 As shown, in an embodiment, the limiting piece 320 and the center shaft 340 are relatively fixedly arranged. It can be understood that the limiting piece 320 is fixedly connected to the cabinet 200 of the refrigerator, and the limiting piece 320 is connected to the limiting surface. The specific mode of the force between the limiting piece 320 and the limiting surface can be determined according to actual needs.

[0041] For example, the limiting piece 320 can be a rubber block made of rubber, and the rubber block and the connecting rod 310 are relatively slidably arranged. At the same time, the rubber block is connected to the limiting surface. The distance between the arc surface 3111 on the limiting surface and the axis of the center shaft 340 is gradually changed, and the gradual change includes that the distance between the arc surface 3111 and the axis of the center shaft 340 decreases or increases in turn. Therefore, when the door body 100 is opened and closed relative to the cabinet 200, the pressure between the limiting block and the limiting surface increases in turn as the angle increases.

[0042] As shown in the Figure 1 and Figure 4 As shown, in an embodiment, the limiting piece 320 and the center shaft 340 are relatively slidably arranged. For example, the limiting piece 320 can be a rubber block, and the limiting piece 320 and the cabinet 200 are further connected with a spring. The spring can be used to drive the rubber block to be connected to the limiting surface. Therefore, by arranging the limiting piece 320 to be slidably arranged, the limiting piece 320 can be allowed to be in contact with the limiting surface under the action of the spring. At the same time, under the action of the spring, the actual damping effect can be effectively improved.

[0043] As shown in the Figures 2 to 4 As shown, in an embodiment, the end of the connecting rod 310 is further connected with a limiting protrusion 330, and the limiting protrusion 330 and the connecting rod 310 are fixedly connected. The limiting rod can be used to limit the limit angle between the door body 100 and the cabinet 200, so as to improve the actual use effect of the device.

[0044] To sum up, the application discloses a damping buffer structure and a vehicle-mounted refrigerator, wherein the distance between the arc surface 3111 and the axis of the central shaft 340 is gradually changed, so as to adjust the force applied by the limiting piece 320 to the connecting rod 310. In the direction from the initial end 3110 to the end end 3112, the force is gradually increased, so that the damping between the door body 100 and the box body 200 can be adjusted according to the opening angle of the door body 100. At the same time, the damping effect between the door body 100 and the box body 200 is further realized by the friction between the limiting piece 320 and the connecting rod 310.

[0045] Therefore, the problem that the damping effect of the door body 100 of the existing vehicle-mounted refrigerator is poor in the actual opening and closing process and it is difficult to adjust the damping according to the opening angle of the door body 100 can be effectively improved.

[0046] Therefore, the application effectively overcomes some practical problems in the prior art, so it has high utilization value and use significance.

[0047] The above examples only exemplarily illustrate the principles and effects of the application, and are not used to limit the application. Any person skilled in the art can modify or change the above examples without departing from the spirit and scope of the application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the application should be covered by the claims of the application.
