The handle is movably disposed between the first and second side plates at the top of the base. The handle has a grip portion protruding from the top of the base, and the grip portion has a handle slot near the first side plate. The assist mechanism is disposed within the base and connected to the handle. When force is applied to the handle, it can move along the width of the base and drive the assist mechanism to achieve door-opening assistance. The assist mechanism comprises two sets, symmetrically arranged at both ends within the base. Each set assists... Each mechanism includes a connecting rod and a top plate; the connecting rod is rotatably connected to the box base; the first end of the connecting rod is rotatably connected to the top plate, and the first side plate of the box base has a top plate through-hole near the top plate, and the end of the top plate moves through the top plate through-hole of the box base; the second ends of the connecting rods of the two sets of assist mechanisms are respectively rotatably connected to the two ends of the handle, and when the handle is pressed, it moves towards the second side plate along the width direction of the box base, and the second end of the connecting rod moves towards the second side plate while rotating the handle, and the first end of the connecting rod moves towards the first side plate while rotating, thereby pushing the end of the top plate forward towards the first side plate.

[0006] In the optimized design, the connecting rod has a shaft hole near its middle portion, and the end of the housing has a main shaft corresponding to the shaft hole. The main shaft is inserted into the shaft hole of the connecting rod, allowing the connecting rod to be rotatably connected to the housing.

[0007] Furthermore, a return spring is fitted on the main shaft. One end of the return spring abuts against the housing and the other end abuts against the connecting rod. When the handle is pressed, the return spring is also compressed and stores force. After the return spring releases the force, it can push the handle to move along the width direction of the housing towards the first side plate.

[0008] Furthermore, the housing has a first insertion hole near the main shaft, and the connecting rod has a second shaft hole near the shaft hole. The two ends of the return spring are respectively fastened into the first insertion hole and the second shaft hole, so that the two ends of the return spring abut against the housing and the connecting rod respectively.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Example

[0032] refer to Figures 1 to 10 A refrigerator door-opening handle includes a base 1, a handle 2, and an assist mechanism. The base 1 is a long, rectangular shell structure with a first side plate 11 and a second side plate 12. The handle 2 is movably disposed between the first side plate 11 and the second side plate 12 at the top of the base 1. The handle 2 has a grip portion 21 protruding from the top of the base 1, and the grip portion 21 has a handle slot 22 on the side near the first side plate 11. The assist mechanism is disposed inside the base 1 and connected to the handle 2. When the handle 2 is subjected to force, it can move along the width direction of the base 1 and drive the assist mechanism to achieve door-opening assistance.

[0033] For details, please refer to the following: Figure 2 and Figure 3The assist mechanism includes two sets, symmetrically arranged at both ends within the box base 1. Each set of assist mechanisms includes a connecting rod 3 and a top plate 4. The connecting rod 3 is rotatably connected to the box base 1. The first end of the connecting rod 3 is rotatably connected to the top plate 4. The first side plate 11 of the box base 1 has a top plate through-hole 13 near the top plate 4. The end of the top plate 4 moves through the top plate through-hole 13 of the box base 1. The second ends of the connecting rods 3 of the two sets of assist mechanisms are rotatably connected to both ends of the handle 2. When the handle 2 is pressed, it moves along the width direction of the box base 1 towards the second side plate 12. The second end of the connecting rod 3 moves towards the second side plate 12 while rotating with the handle 2. The first end of the connecting rod 3 moves towards the first side plate 11 while rotating, thereby pushing the end of the top plate 4 forward towards the first side plate 11.

[0034] For details, please refer to the following: Figure 9 and Figure 10 When the refrigerator door assisted opening handle with the above structure is used to assist in opening and closing the refrigerator door, as described below, when the door 9 needs to be opened, the user presses the handle 2 through the handle slot 22 of the handle 2, and the handle 2 moves towards the second side plate 12, thereby driving the connecting rod 3 to rotate and push the end of the top piece 4 towards the front of the first side plate 11. That is, the end of the top piece 4 is pushed towards the front of the frame of the cabinet 8, and then the reaction force of the end of the top piece 4 on the cabinet 8 is used to assist in opening the door 9.

[0035] Furthermore, the top piece 4 also has an elastic head 40 at its end. When the end of the top piece 4 is pushed against the front of the frame of the box 8, the elastic head 40 buffers the force between the top piece 4 and the frame of the box 8, reducing door opening noise and ensuring the durability of the top piece 4.

[0036] Furthermore, the connecting rod 3 has a shaft hole 34 near its middle portion, and a main shaft 14 is located at the end of the housing 1 corresponding to the shaft hole 34. The main shaft 14 is inserted into the shaft hole 34 of the connecting rod 3, allowing the connecting rod 3 to be rotatably connected to the housing 1. This structure, through the engagement of the shaft hole 34 of the connecting rod 3 with the main shaft 14 within the housing 1, enables the connecting rod 3 to be rotatably connected to the housing 1.

[0037] For details, please refer to the following: Figures 4 to 6 Furthermore, a return spring 5 is fitted onto the main shaft 14, with one end of the return spring 5 abutting against the housing 1 and the other end abutting against the connecting rod 3. When the handle 2 is pressed, the return spring 5 is also compressed and stores force. After the return spring 5 releases its force, it can push the handle 2 along the width direction of the housing 1 towards the first side plate 11, and pull the end of the top piece 4 back towards the first side plate 11. The specific actions are as follows: (See details) Figure 9 and Figure 10 When handle 2 is pressed, connecting rod 3 rotates, which in turn causes one end of return spring 5 to be compressed and store force. (See details...) Figure 7 and Figure 8 After the door 9 is opened, the user releases the handle 2, and the handle 2 is no longer pressed. The elastic force stored in the reset spring 5 is released naturally, which causes the connecting rod 3 to rotate and reset. One end of the rotating and resetting connecting rod 3 pushes the handle 2 to move and reset towards the first side plate 11, and the other end of the connecting rod 3 pulls the end of the top plate 4 back towards the first side plate 11.

[0038] Furthermore, the housing 1 has a first insertion hole 15 near the main shaft 14, and the connecting rod 3 has a second shaft hole 341 near the shaft hole 34. The two ends of the return spring 5 are respectively fastened into the first insertion hole 15 and the second shaft hole 341, thereby causing the two ends of the return spring 5 to abut against the housing 1 and the connecting rod 3 respectively. In the above structure, the cooperation between the two ends of the return spring 5 and the first insertion hole 15 and the second shaft hole 341 achieves contact between the two ends of the return spring 5 and the housing 1 and the connecting rod 3. The return spring 5 can stably store pressure as the connecting rod 3 rotates, ensuring a stable release of elastic force from the return spring 5 to the connecting rod 3.

[0039] The housing 1 also has a protective post 16 on the outer side corresponding to the return spring 5. The protective post 16 is coaxially arranged with the main shaft 14, and the first insertion hole 15 is located in the gap between the protective post 16 and the main shaft 14. In the above structure, the protective post 16 further provides limiting protection for the return spring 5, ensuring that the return spring 5 undergoes uniform and stable elastic deformation within a limited radial space, and ensuring the effectiveness of the return spring 5 in automatically resetting the handle 2.

[0040] Furthermore, the first end of the connecting rod 3 has a first rotating shaft 35, and the top plate 4 has an elongated top plate shaft hole 45 corresponding to the first rotating shaft 35. The first rotating shaft 35 is inserted into the top plate shaft hole 45, so that the first rotating shaft 35 of the connecting rod 3 can rotate and move along the top plate shaft hole 45. Also, the handle 2 has elongated handle shaft holes 25 at both ends, and the second end of the connecting rod 3 has a second rotating shaft 36 inserted into the handle shaft hole 25, so that the second rotating shaft 36 of the connecting rod 3 can rotate and move along the handle shaft hole 25. The above structure, through the elongated top plate shaft hole 45 and handle shaft hole 25, realizes the relative rotation and movement space between the two ends of the connecting rod 3 and the top plate 4 and handle 2, ensuring the stability of the linkage between the handle 2, connecting rod 3, and top plate 4.

[0041] In this embodiment, the specific installation structure of the box base 1 and the handle 2 is as follows: the top of the box base 1 has a top opening, and the top two ends of the box base 1 are respectively equipped with cover plates 10, so that the middle part of the box base 1 forms a handle movable through-hole. The handle 2 has end plate portions 26 at both ends of the hand-held part 21. The end plate portions 26 at both ends of the handle 2 are respectively located inside the top two ends of the box base 1, so that the hand-held part 21 of the handle 2 is exposed through the handle movable through-hole, thereby facilitating the installation of the two sets of assistive mechanisms and the handle 2.

[0042] For details, please refer to the following: Figure 11 and Figure 12 The refrigerator using the refrigerator-assisted door handle of this embodiment includes a cabinet 8 and a door 9. The door 9 is hinged to the front of the cabinet 8 by a door hinge 90. The refrigerator-assisted door handle of this embodiment is installed on the side of the door 9 away from the door hinge 90. The housing 1 is installed inside the door 9, with its top protruding from the side of the door 9. The first side plate 11 of the housing 1 is located near the rear of the door 9, and the second side plate 12 is located near the front of the door 9. The end of the top plate 4 is movably protruding from the back of the door 9 and is located facing the front of the frame of the cabinet 8. When the handle 2 is pressed, it can press the end of the top plate 4 against the front of the frame of the cabinet 8, thereby realizing door opening assistance.

[0043] The base 1 is pre-installed on the door body 9 before the foaming process, and is then securely fixed to the door body 9 during the foaming process. After the foaming process of the door body 9 is completed, the power assist mechanism, handle 2, and other components are then sequentially installed on the base 1. For specific usage instructions, please refer to [the relevant documentation / reference]. Figure 9 and Figure 10 When the user presses the handle 2 through the handle slot 22, the handle 2 moves toward the second side plate 12, thereby driving the connecting rod 3 to rotate and push the end of the top plate 4 toward the front of the frame of the cabinet 8. The end of the top plate 4 presses against the front of the frame of the cabinet 8 to generate a reaction force, which helps the door 9 to open, thereby greatly saving the force required to open the refrigerator door, improving the comfort of opening the refrigerator door, and ensuring the comfort of using the refrigerator.
