[0002] A refrigerator door consists of a door panel, a door body, and a mounting element connecting the door panel and the door body. The door body has a mounting hole. One end of the mounting element is fixed to the door panel with a screw, and the other end of the mounting element is used to engage with the mounting hole, thereby attaching the door panel and the door body together. In related structures, the mounting positions of the mounting elements are usually measured on the door panel, marked at the corresponding locations, and then screwed in at the marked locations to secure the mounting elements.

The term "and / or" used in the specification of this application includes any and all combinations of one or more of the relevant listed items.

[0030] See also Figures 1 to 4 The present application provides a refrigerator door panel positioning and mounting structure 100. The refrigerator door 200 includes a door panel 210, a door body 220, and a hanging member. The door body 220 has a hanging hole 221. The refrigerator door panel positioning and mounting structure 100 is used to open a mounting hole 211 on the door panel 210, and the mounting hole 211 is corresponding to the hanging hole 221. One end of the hanging member is mounted to the mounting hole 211, and the other end is hung and matched with the hanging hole 221. The refrigerator door panel positioning and mounting structure 100 includes a positioning mark assembly 101. The positioning mark assembly 101 includes a shell 110, a push-out mechanism 120, and a positioning mark assembly 101. and the punch 130, one end of the shell 110 is used to be installed in the hanging hole 221, and the other end is arranged near the door panel 210, the ejection mechanism 120 and the punch 130 are both movably installed in the shell 110, and at least part of the punch 130 extends from the end of the shell 110 close to the door panel 210, and is used to contact the door panel 210; as the punch 130 responds to the extrusion of the door panel 210 and moves a preset distance toward the ejection mechanism 120, the ejection mechanism 120 can eject the punch 130 toward the door panel 210, and make the punch 130 punch out the mounting hole 211 on the door panel 210.

[0031] It is understood that when punching the door panel 210 by setting the positioning mark assembly 101, one end of the housing 110 can be first mounted to the hanging hole 221, and then the door panel 210 can be placed against the punch 130 and pressed against the door body 220. As the punch 130 moves a preset distance toward the ejection mechanism 120 in response to the pressure of the door panel 210, the ejection mechanism 120 can eject the punch 130 toward the door panel 210, causing the punch 130 to punch the mounting hole 211 in the door panel 210. In this way, the position of the mounting hole 211 punched in the door panel 210 can be ensured to correspond to the position of the hanging hole 221 on the door body 220, thereby ensuring that when one end of the hanging member is mounted to the mounting hole 211, the other end can be hooked and matched with the hanging hole 221 on the door body. In addition, punching the door panel 210 using the positioning mark assembly 101 is simple and efficient.

[0032] The hanging member can be configured as a hook, one end of which is fixed to the mounting hole 211 via a screw, and the other end is used to be mounted in the hanging hole 221. The end of the housing 110 that is mounted in the hanging hole 221 has the same shape as the end of the hanging member that is mounted in the hanging hole 221. Moreover, the center position of the housing 110 when mounted in the hanging hole 221 coincides with the center position of the hanging member when mounted in the hanging hole 221. This helps ensure the accuracy of the position of the positioning mark assembly 101 when punching the mounting hole 211 in the door panel 210.

[0033] A through hole is provided at one end of the shell 110 close to the door panel 210, and the punch 130 is needle-shaped with a large cross-sectional area at one end and a small cross-sectional area at the other end. The end of the punch 130 with a larger cross-sectional area is located inside the shell 110, and the end of the punch 130 with a smaller cross-sectional area extends out from the through hole on the shell 110.

[0034] like Figures 4 to 7 As shown, the ejection mechanism 120 includes an elastic ejection portion 121 and a trigger seat 122. The trigger seat 122 is located axially between the punch 130 and the elastic ejection portion 121 along the housing 110. The trigger seat 122 has a triggered state and a de-triggered state. Specifically, when the trigger seat 122 is in the de-triggered state, the punch 130 can push the trigger seat 122 to squeeze the elastic ejection portion 121 axially along the housing 110. When the punch 130 moves to a predetermined distance, the trigger seat 122 switches to the triggered state, the elastic ejection portion 121 resets, and the punch 130 is ejected through the trigger seat 122.

[0035] It can be understood that in the process of the door panel 210 axially squeezing the punch 130 along the shell 110, the punch 130 squeezes the elastic pushing portion 121 through the trigger seat 122 so that the elastic pushing portion 121 accumulates elastic potential energy. When the door panel 210 continues to squeeze the punch 130 axially along the shell 110 to a preset distance, the trigger seat 122 switches to a trigger state to release the elastic pushing portion 121, so that the elastic pushing portion 121 can be reset and push the punch 130 toward the door panel 210 along the circumference of the shell 110 through the trigger seat 122, and the punch 130 impacts a mounting hole 211 on the door panel 210.

[0036] Specifically, the elastic pushing portion 121 includes an impact block 123 and a first elastic member 124. Along the axial direction of the shell 110, one end of the first elastic member 124 is connected to the inner wall of the shell 110, and the other end is connected to the impact block 123. The impact block 123 is provided with a groove 1231 on the end surface facing the trigger seat 122, and the groove 1231 has a flared opening 1232. When the trigger seat 122 is in a non-triggering state, the trigger seat 122 is tilted relative to the axial direction of the shell 110, and one end of the trigger seat 122 is connected to the impact block 123. The head 130 abuts, and the other end abuts against the surface of the flare 1232. As the trigger seat 122 slides along the surface of the flare 1232, the axial inclination of the trigger seat 122 relative to the shell 110 gradually decreases, and the first elastic member 124 is compressed by the impact block 123; when the trigger seat 122 slides to disengage from the surface of the flare 1232 and moves into the groove 1231, the trigger seat 122 switches to the trigger state, the trigger seat 122 is coaxially arranged with the shell 110, and the first elastic member 124 is reset.

[0037] Specifically, the cross-sectional area of the flared opening 1232 gradually decreases along the direction from the trigger seat 122 to the impact block 123. As the trigger seat 122 slides along the surface of the flared opening 1232, it gradually deflects about its contact point with the punch 130, thereby gradually decreasing its axial tilt relative to the housing 110. When the trigger seat 122 disengages from the surface of the flared opening 1232 and moves into the groove 1231, the groove 1231 provides a clearance for the trigger seat 122, allowing the first elastic member 124 to reset and push the impact block 123 in the opposite direction. This is until the impact block 123 pushes the trigger seat 122 in the opposite direction through the bottom wall of the groove 1231, further pushing the punch 130 toward the door panel 210, thereby punching the mounting hole 211 in the door panel 210. That is, by providing the flared opening 1232 and the groove 1231 on the impact block 123 , the trigger seat 122 can be switched between the non-trigger state and the trigger state during the process of moving the trigger seat 122 axially toward the impact block 123 along the housing 110 .

[0038] Optionally, in one embodiment, the surface of the flare 1232 is configured as an arc surface, so that at least part of the trigger seat 122 can be separated from the surface of the flare 1232 and moved into the groove 1231, thereby facilitating the trigger seat 122 to switch from the non-trigger state to the trigger state.

[0039] The ejection mechanism 120 also includes a second elastic member 126, one end of which is connected to the trigger seat 122 and the other end is connected to the inner wall of the shell 110; when the trigger seat 122 is in the non-triggered state, the second elastic member 126 is tilted relative to the axis of the shell 110; as the trigger seat 122 slides along the surface of the flared opening 1232, the second elastic member 126 is compressed and gradually drives the trigger seat 122 to deflect, so that the axial inclination of the trigger seat 122 relative to the shell 110 gradually decreases; when the trigger seat 122 switches to the triggered state, the second elastic member 126 is coaxially arranged with the shell 110. It is understood that the second elastic member 126 is used to keep the trigger seat 122 tilted relative to the axis of the housing 110 when in the non-triggered state, and is used to drive the trigger seat 122 to gradually deflect around the abutment position with the punch 130 when the trigger seat 122 slides along the surface of the flared opening 1232, so as to facilitate the trigger seat 122 to separate from the surface of the flared opening 1232 and move into the groove 1231. This facilitates the switching of the trigger seat 122 from the non-triggered state to the triggered state.

[0040] Specifically, the trigger seat 122 includes a coaxially arranged seat body 1221 and a trigger rod 1222 . The cross-sectional area of the seat body 1221 is larger than the cross-sectional area of the trigger rod 1222 . The seat body 1221 is used to abut against the punch 130 , and the trigger rod 1222 is used to slide with the flare 1232 .

[0041] Furthermore, a limiting step is provided on the seat body 1221 , and the second elastic member 126 is configured as a spring. The spring is sleeved on the outer periphery of the trigger seat 122 , and one end of the spring abuts against the limiting step, and the other end abuts against the inner wall of the shell 110 .

[0042] Optionally, in one embodiment, the punch 130 is provided with an arcuate groove 131, and the shape of the seat body 1221 is adapted to the shape of the arcuate groove 131. This allows the end of the trigger seat 122 that abuts the punch 130 to fit more closely with the punch 130, thereby facilitating the deflection of the trigger seat 122 about the abutment position with the punch 130, that is, facilitating the trigger seat 122 to switch to being coaxial with the housing 110, thereby preparing the trigger seat 122 to enter the trigger state.

[0043] The housing 110 includes a base 111, an outer shell 112, and a connecting sleeve 113 connecting the base 111 and the outer shell 112. The connecting sleeve 113 has a baffle 1131. The baffle 1131 has a first side 1132 and a second side 1133 opposite to each other. A first space 114 is formed between the first side 1132 and the outer shell 112, and a second space 115 is formed between the second side 1133 and the base 111. The baffle 1131 is provided with a hole connecting the first space 114 and the second space 115. Through hole 116; punch 130, trigger seat 122, and second elastic member 126 are all located in first space 114, and the end of second elastic member 126 away from trigger seat 122 is used to abut and cooperate with first side 1132. Impact block 123 and first elastic member 124 are both located in second space 115, and impact block 123 has an open end surface for abutting and cooperating with second side 1133. At least a portion of trigger seat 122 can pass through through hole 116 and abut and cooperate with flared opening 1232. The base 111 has the same shape and size as the hanging member and is used to hang and cooperate with the hanging hole 221.

[0044] The cross-sectional area of the through hole 116 is larger than the cross-sectional area of the flared opening 1232 , so as to avoid interference between the trigger seat 122 and the baffle 1131 .

[0045] Optionally, in one embodiment, the connection position between the connecting sleeve 113 and the outer shell 112 along the axial direction of the housing 110 is configured to be adjustable. In this way, the distance between the outer shell 112 and the first side 1132 along the axial direction of the housing 110 is also configured to be adjustable, thereby adjusting the capacity of the first space 114 and further adjusting the compression stroke of the second elastic member 126.

[0046] In another embodiment, the connection position between the connecting sleeve 113 and the base 111 along the axial direction of the housing 110 is configured to be adjustable. In this way, the distance between the base 111 and the second side 1133 along the axial direction of the housing 110 is also configured to be adjustable, thereby adjusting the capacity of the second space 115 and further adjusting the compression stroke of the first elastic member 124.

[0047] Optionally, in one embodiment, one end of the connecting sleeve 113 is sleeved around the outer periphery of the housing 112 and is threadedly connected to the housing 112; the other end of the connecting sleeve 113 is sleeved around the outer periphery of the base 111 and is threadedly connected to the base 111. In this way, by screwing the housing 112 or the base 111, the connection position of the housing 112 or the base 111 and the connecting sleeve 113 can be adjusted along the axial direction of the housing 110.

[0048] like Figure 2 and Figure 8As shown, the refrigerator door panel positioning and installation structure 100 also includes a fixing seat 140, which has a first card slot 141 and a second card slot 142, and the second card slot 142 and the first card slot 141 are arranged along the pushing direction of the punch 130; the first card slot 141 is used to cooperate with the corner positioning of the door panel 210, and the second card slot 142 is used to cooperate with the corner positioning of the door body 220.

[0049] It should be noted that the corner of the door panel 210 refers to the location where two adjacent side surfaces of the door panel 210 intersect along its own circumference. Similarly, the corner of the door body 220 refers to the location where two adjacent side surfaces of the door body 220 intersect along its own circumference. By providing the first and second slots 141 and 142 on the fixing base 140, the door panel 210 and the door body 220 can be aligned, thereby facilitating improved assembly accuracy of the door panel 210 and the door body 220. Optionally, the number of fixing bases 140 is configured to be four, with the four fixing bases 140 being distributed at the four corners of the door panel 210.

[0050] Specifically, the fixing base 140 has an opening 144, a second partition 145, and a first partition 146 spaced apart along the direction of ejection of the punch 130. A second slot is formed between the opening 144 and the second partition 145, and a first slot 141 is formed between the first partition 146 and the second partition 145. The door body 220 can be inserted into the second slot 142 through the opening 144.

[0051] The refrigerator door panel positioning and mounting structure 100 also includes an adjusting member 150. One end of the adjusting member 150 is connected to the first partition 146, and the other end extends into the first slot 141 and is used to cooperate with the second partition 145 to clamp the door panel 210. In addition, the distance between the end of the adjusting member 150 extending into the first slot 141 and the second partition 145 is configured to be adjustable. In this way, the adjusting member 150 can cooperate with the fixing base 140 to clamp door panels 210 of different thicknesses, thereby improving the applicability of the refrigerator door panel positioning and mounting structure to door panels 210 of different thicknesses.

[0052] Optionally, a gasket 151 is mounted on the end of the adjusting member 150 that extends into the first slot 141. The gasket 151 prevents the end of the adjusting member 150 that extends into the first slot 141 from scratching the door panel 210. The adjusting member 150 is configured as a bolt that is threadedly connected to the first partition plate 146. Thus, the depth of the end of the adjusting member 150 that extends into the first slot 141 can be adjusted by tightening the bolt.

[0053] The process of punching holes in the door panel 211 of the refrigerator door positioning and installation structure provided in this application is as follows:
