Description

Technical Field

[0001] This invention belongs to the field of refrigerator technology, and in particular relates to an assistive handle structure. Background Technology

[0002] When refrigerators and freezers are in cooling mode, a large negative pressure is generated inside the unit after the door is opened or closed, which can cause the door to lock, making it difficult to open and affecting the user experience. Forcing the door open can also cause the refrigerator or freezer to tip over or damage the door handle.

[0003] For example, CN218815737U discloses an assisted door handle and a refrigerator. When the door is opened with assistance, a pressing force is applied to the push handle, and the toothed transmission mechanism drives the assisted push rod to move towards the fixed magnet, thereby continuously reducing the distance between the movable magnet and the fixed magnet and continuously increasing the repulsive force, thus realizing assisted door opening.

[0004] However, the aforementioned prior art includes a gear transmission mechanism, a first rack on the push rod body that meshes with the gear, and a second rack on the push handle that meshes with the gear. Power is transmitted through the meshing of the gear and rack. This method makes the overall structure of the power assist handle more complex and larger in size, resulting in higher installation difficulty and production cost. Summary of the Invention

[0005] The purpose of this invention is to provide an assisted handle structure, which drives the transmission column to rotate by cooperating with the first slide groove, and drives the push rod to extend out of the box seat through the second slide groove of the transmission column, thereby realizing assisted door opening. This invention solves the problems of existing assisted handle structures being complex and bulky, resulting in installation difficulties and high production costs.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to an assistive handle structure, comprising a base with a mounting groove; a handle is connected within the mounting groove, and both ends of the mounting groove are rotatably connected to a transmission column, with a push rod movably inserted therethrough; the circumferential surface of the transmission column has a first sliding groove and a second sliding groove, the first and second sliding grooves forming a spiral groove structure, and the spiral directions of the first and second sliding grooves being opposite; an elastic element is fixedly connected between the handle and the inner wall of the mounting groove, and a first guide post cooperating with the first sliding groove is fixedly connected to the end of the handle; a second guide post cooperating with the second sliding groove is fixedly connected to the side of the push rod, for pulling the handle, using the first guide post to drive the transmission column to rotate, and using the second sliding groove to drive the second guide post to move, so that the push rod extends out of the base, realizing assisted door opening.

[0008] As a preferred embodiment of the present invention, the box base is provided with a third sliding groove, and the handle includes a first support plate and a second support plate, wherein the first support plate and the second support plate are integral structures and form an L-shaped structure; the first support plate and the third sliding groove are slidably engaged.

[0009] As a preferred embodiment of the present invention, the box base is provided with a fourth sliding groove, and the push rod is slidably engaged with the fourth sliding groove.

[0010] As a preferred embodiment of the present invention, the first guide post is connected to the end of the second support plate.

[0011] As a preferred embodiment of the present invention, a first positioning post is fixedly connected to the side of the second support plate, and a second positioning post corresponding to the position of the first positioning post is fixedly connected to the inner wall of the mounting groove; the two ends of the elastic member are respectively connected to the first positioning post and the second positioning post.

[0012] As a preferred embodiment of the present invention, the two side walls of the mounting trough are provided with connection holes, and the end of the transmission column is connected to a rotating shaft that mates with the connection hole, so that the transmission column is rotatably connected to the box base.

[0013] As a preferred embodiment of the present invention, the helix angle of the first groove is greater than that of the second groove.

[0014] The present invention has the following beneficial effects:

[0015] This invention utilizes two rotatable transmission columns connected within the housing. The circumferential surfaces of these transmission columns have first and second grooves. First guide columns at both ends of the handle engage with the first grooves of the two transmission columns, and second guide columns on the two push rods engage with the second grooves of the two transmission columns. This allows the transmission columns to rotate when the handle is pulled, driving the push rods to extend and push against the refrigerator body, thus providing assistance in opening the door. By employing transmission columns, the overall structure of the assisted handle is compact, requiring minimal space and allowing for installation on thinner doors, improving its overall adaptability.

[0016] Meanwhile, the overall transmission structure is simple and efficient, which makes the overall assembly process simple and production convenient, thus reducing the overall production difficulty and cost.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] Example 1

[0031] Please see Figures 1-3 As shown, the present invention is an assist handle structure, including a base 1, which is installed on the refrigerator door. The base 1 is provided with an installation groove, and a handle 2 is connected in the installation groove. Both ends of the installation groove are rotatably connected to a transmission column 3, and a push rod 4 is movably inserted.

[0032] Among them, such as Figure 3 and 5 As shown, connection holes 101 are provided on both sides of the upper and lower ends of the mounting trough. The end of the transmission column 3 is connected to a rotating shaft 303 that cooperates with the connection hole 101, so that the transmission column 3 is rotatably connected to the box base 1.

[0033] The circumferential surface of the transmission column 3 is provided with a first groove 301 and a second groove 302. The first groove 301 and the second groove 302 form a spiral groove structure, and the spiral directions of the first groove 301 and the second groove 302 are opposite.

[0034] An elastic element 5 is fixedly connected between the handle 2 and the inner wall of the mounting groove. The elastic element 5 is a spring. The end of the handle 2 is fixedly connected to a first guide post 203 that cooperates with the first slide groove 301. The handle 2 and the first guide post 203 are an integral structure.

[0035] like Figure 6 As shown, the push rod 4 has a second guide post 401 fixedly connected to its side, which cooperates with the second slide groove 302. The push rod 4 and the second guide post 401 are also an integral structure.

[0036] like Figure 7 As shown, when the refrigerator door needs to be opened, by pulling the handle 2, the handle 2 moves relative to the box seat 1, compressing the elastic element 5, and using the first guide post 203 to cooperate with the first slide groove 301, the transmission post 3 is driven to rotate. During the rotation of the transmission post 3, the second guide post 401 is driven to move through the second slide groove 302, so that the push rod 4 extends out of the box seat 1, and the end of the push rod 4 pushes against the refrigerator body, so that the door body is subjected to a reverse thrust, thereby realizing assisted opening of the door.

[0037] The helix angle of the first slide groove 301 is greater than that of the second slide groove 302. This makes it easier for the first guide post 203 to drive the transmission post 3 to rotate when the handle 2 is pulled, and the second slide groove 302 to drive the second guide post 401 to move, allowing the push rod 4 to extend out of the box seat 1, making the opening process more convenient and effortless. After the handle 2 is released, under the action of the elastic element 5, the handle 2 returns to its original position and drives the transmission post 3 to reverse, which in turn drives the push rod 4 to retract and return to its original position.

[0038] By utilizing the first and second slide grooves 301 and 302 on the transmission column 3 to achieve power transmission, the overall structure of the power-assist handle is compact, occupying little space, and can be installed on thinner door panels, improving its overall adaptability. At the same time, the simple and efficient overall transmission structure simplifies the assembly process, facilitates production, and helps reduce overall production difficulty and costs.

[0039] Example 2

[0040] like Figure 3 and 4 As shown, the box base 1 has a third sliding groove 103, and the handle 2 includes a first support plate 201 and a second support plate 202. The first support plate 201 and the second support plate 202 are an integral structure and form an L-shaped structure.

[0041] The first guide post 203 is connected to the end of the second support plate 202. The first support plate 201 and the third slide groove 103 are in sliding fit, which helps to improve the stability of the handle 2 when sliding. In addition, the second support plate 202 is fixedly connected to the side of the first positioning post 204, and the inner wall of the mounting groove is fixedly connected to the second positioning post 104 corresponding to the position of the first positioning post 204.

[0042] The two ends of the elastic element 5 are connected to the first positioning post 204 and the second positioning post 104 respectively. The elastic element 5 can be a spring, and the two ends of the spring are respectively sleeved on the first positioning post 204 and the second positioning post 104 to realize the installation of the elastic element 5.

[0043] Meanwhile, the box base 1 is provided with a fourth slide groove 102, and the push rod 4 slides in the fourth slide groove 102. The cooperation between the push rod 4 and the fourth slide groove 102 helps to improve the stability of the push rod 4 when it moves in extension and retraction, thereby improving the overall stability and reliability of use.
