[0036] like Figures 1 to 10As shown, the present application provides a refrigerator 100, which includes a box body 10, a door body 20 and a push switch 30, the door body 20 is installed on the box body 10 and is provided with a trigger surface 21, and the surface of the box body 10 facing the door body 20 is defined as the first surface 11 (that is, the surface of the box body 10 closest to the door body 20 is the first surface 11); the push switch 30 includes a shell 31, a trigger rod 32 and an elastic member 33, the shell 31 is installed on the box body 10, the elastic member 33 is installed on the shell 31, and one end of the trigger rod 32 abuts against the elastic member 33. On the elastic member 33, the other end protrudes from the first surface 11 and its end surface is defined as a contact surface 321. The contact surface 321 can contact the trigger surface 21 as the trigger rod 32 is subjected to force to trigger the press switch 30; wherein, the maximum stroke of the trigger rod 32 is Z, the actual value between the first surface 11 and the trigger surface 21 is X, the theoretical value between the first surface 11 and the trigger surface 21 is X0, and the upper deviation between X and X0 is m, and the compensation displacement value a between the contact surface 321 and the trigger surface 21 satisfies: m<a<Z.

[0037] In this way, by making the compensation displacement value a between the abutting surface 321 and the triggering surface 21 satisfy: m<a<Z; in this way, when X=X0+m, the assembly deviation between the box body 10 and the door body 20 can be compensated by the compensation displacement value a, and because m<a, the abutting surface 321 and the triggering surface 21 can always be made to have an interference fit; at the same time, a<Z, so that it can be ensured that the elastic member 33 can be normally compressed (overpressure protection) during the triggering process. In this way, m<a<Z can effectively ensure that the push switch 30 can be effectively triggered to ensure the normal opening of the door body 20, thereby eliminating the press failure phenomenon caused by assembly deviation.

[0038] For example, Z = 6.5 mm, Y = 6 mm, X0 = 4 mm, m = 1 mm, n = 1 mm, then the value of a can be 3 mm, 3.5 mm, etc. For another example, Z = 5 mm, Y = 4.5 mm, X0 = 3 mm, m = 1 mm, n = 1 mm, then the value of a can be 2.5 mm, 3 mm, etc. Here, the values ​​of m, a, Z, and X are the dimensions along the axis of the trigger rod 32.

[0039] It should be explained that the lower deviation n of X0, that is, X0+m≥X≥X0-n. When X=X0-n, in actual assembly, the door body 20 is relatively close to the box body 10. The trigger surface 21 and the abutting surface 321 are already in contact, and no compensation a is required. At the same time, when X=X0+m, in actual assembly, the door body 20 is relatively far away from the box body 10. To ensure that the door body 20 is pressed, there is a trigger signal, the trigger surface 21 is in contact with the abutting surface 321 and Z>0, so a<Z.

[0040] In one embodiment, a trigger protrusion 211 is provided on the trigger surface 21, and the trigger protrusion 211 is used to cooperate with the trigger rod 32. In this way, the trigger protrusion 211 is used to further compensate the distance between the door body 20 and the box body 10, so as to ensure that during the pressing process, the trigger surface 21 and the abutting surface 321 are interference-fitted, so that the push switch 30 can be effectively triggered.

[0041] Furthermore, when the door body 20 is pressed, the maximum distance that the door body 20 can move is L, and the theoretical distance between the first surface 11 and the abutting surface 321 is Y, wherein L, Y, and Z satisfy the relationship: Z>Y>L. It should be explained that due to the deviation of X0, in order to ensure that after actual assembly, pressing the door body 20 can cause the push switch 30 to operate. During design, an interference is made between the trigger surface 21 and the abutting surface 321, and the interference value (i.e., the compensation displacement value) is a (a=Y-X0). That is, during assembly, when the door body 20 is closed, the door body 20 will push the trigger rod 32 to move a distance, the theoretical value of which is a, so that the elastic member 33 is further compressed. Thereafter, the door body 20 is pressed, and the door body 20 pushes the trigger rod 32, so that the push switch 30 senses the pressure and then outputs a signal, thereby realizing the normal opening of the door body 20.

[0042] In one embodiment, if Figure 8 As shown, the housing 31 is detachably connected to the box body 10. In this way, the housing 31 can be easily disassembled and installed.

[0043] Here, the housing 31 and the box body 10 can be detachably connected via a threaded member 313 or a snap member. Here, the threaded member 313 is configured as a bolt or a screw.

[0044] Furthermore, if Figure 5 As shown, a switch bracket 12 is provided on the box body 10, and the switch bracket 12 is formed with the above-mentioned first surface 11; wherein, a through hole 111 is opened on the first surface 11, and one end of the trigger rod 32 having abutting surface 321 passes through the through hole 111 for matching with the trigger surface 21.

[0045] In one embodiment, the switch bracket 12 is detachably mounted on the box body 10. Here, the switch bracket 12 is detachably connected to the box body 10 via a screw or a snap-fit ​​member.

[0046] Furthermore, in order to enhance the structural strength of the switch bracket 12, a plurality of spaced reinforcing members 121 are provided on the switch bracket 12. Here, the reinforcing members 121 are provided integrally with the switch bracket 12, which facilitates processing and can enhance the structural strength of the switch bracket 12.

[0047] In one embodiment, the maximum stroke Z of the trigger rod 32 and the maximum compression M of the elastic member 33 satisfy: Z≤M. In this way, when the trigger rod 32 is at the maximum stroke, the elastic member 33 can still be compressed. In this way, the trigger rod 32 can effectively operate normally.

[0048] Please continue to refer to Figure 5 The push switch 30 further includes a support plate 34 and a circuit board 35. The support plate 34 is received in the housing 31 and divides the interior of the housing 31 into a first cavity 311 and a second cavity 312. The circuit board 35 is located in the first cavity 311. The end of the elastic member 33 away from the trigger rod 32 acts on the support plate 34. In this way, the circuit board 35 is received in the separate first cavity 311 divided by the support plate 34, so that the circuit board 35 can be protected separately.

[0049] Furthermore, a mounting seat 341 is provided on the support plate 34, a trigger seat 342 is installed on the mounting seat 341, and one end of the elastic member 33 away from the trigger rod 32 is sleeved on the trigger seat 342. In this way, not only can the installation and position limiting of the elastic member 33 be achieved, but also, through the transmission of the mounting seat 341, the trigger seat 342 and the elastic member 33, the transitional contact between the trigger rod 32 and the circuit board 35 is avoided, that is, the damage of the press switch 30 is avoided when the door is closed with too much force.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0051] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
