Description

Technical Field

[0001] This invention relates to the field of door handle technology, and specifically to a thin, concealed power-assisted door handle. Background Technology

[0002] Currently, large single-door upright freezers are prone to negative pressure after cooling, causing difficulty in opening the door and a poor customer experience. To solve this problem, many manufacturers have designed and installed power handles for large refrigerators and upright freezers to meet customer needs.

[0003] Among them, there are various types of power-assisted handles, including external power-assisted handles and concealed power-assisted handles. Concealed power-assisted handles are mostly used on glass door products. Different handles provide different customer experiences. Power-assisted handles all achieve assistance through the lever principle, and different structures achieve different degrees of assistance.

[0004] The most commonly used type of power handle on the market is the external pull type. External pull handles are relatively expensive and take up product space. The power handle is mainly composed of handle bar, handle seat, torsion spring, handle cover and other components. Due to structural limitations and reliability factors, concealed power handles are mainly used on products with thicker door bodies such as glass doors, and cannot be used on thinner door bodies such as glass doors and steel plate doors. Summary of the Invention

[0005] The purpose of this invention is to provide a thin, concealed power-assisted handle to solve the problems mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions: A thin, concealed power-assisted handle includes a handle base with an inclined guide rail. A handle is slidably connected to the handle base at the inclined guide rail via a connecting shaft. The handle is connected to a lever via a connecting shaft and a second return spring, and is positioned by bends at both ends of the connecting shaft. The bends are movably connected to an oblong hole on the lever. The lever is connected to a stop plate, which is fixedly connected to the handle base by screws. The end of the lever away from the stop plate contacts a limit block. The limit block is connected to a push rod via a first return spring, and a shock-absorbing pad is provided on the push rod.

[0007] Preferably, both ends of the handle base are provided with handle covers, and the handle covers are detachable.

[0008] Preferably, the handle base is made of plastic, and the buckle is made of plastic.

[0009] Preferably, the shock-absorbing pad is made of rubber, and the side of the shock-absorbing pad away from the push rod is close to the housing on which this power handle is used.

[0010] Preferably, the handle is located away from the housing where the power-assisted handle is used.

[0011] Preferably, the connecting shaft moves linearly back and forth on an inclined guide rail on the handle seat through point contact with the handle seat.

[0012] The beneficial effects of this invention are as follows: By modularizing the assembly of the power-assist handle parts, component supply is successfully achieved, resulting in high manufacturing efficiency. The handle, in conjunction with the connecting shaft, increases the strength of the handle. The point contact of the connecting shaft on the inclined guide rail of the handle seat reduces friction, making the use of the power-assist handle smoother. Furthermore, since the handle seat, handle, lever, and push rod are all made of plastic, the injection molding process in existing technology can be used, thereby reducing the cost of parts. On this basis, the thickness of the power-assist handle can be further reduced without affecting the stability of use, thus meeting the requirements for use in thin doors in cabinets. The structure is ingenious and efficient, convenient and smooth to use, and has great application prospects. Attached Figure Description

[0016] 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.

[0017] Reference Figure 1-9 As shown, a thin, concealed power-assisted handle includes a handle base 1, on which an inclined guide rail 13 is provided. A handle 3 is slidably connected to the handle base 1 at the inclined guide rail 13 via a connecting shaft 12. The handle 3 is connected to a second return spring 11 via the connecting shaft 12 and to a lever 9 via bending at both ends of the connecting shaft 12. A stop plate 7 is connected to the lever 9 and is bent and movably connected to the waist-shaped hole on the lever 9. The stop plate 7 is fixedly connected to the handle base 1 via screws 10. The end of the lever 9 away from the stop plate 7 contacts a limit block 8. The limit block 8 is connected to a push rod 5 via a first return spring 6. A shock-absorbing pad 4 is provided on the push rod 5.

[0018] It should be noted that handle covers 2 are provided at both ends of handle base 1. Handle covers 2 are removable. The handle base 1 is made of plastic, the handle 3 is made of plastic, the lever 9 and the push rod 5 are also made of plastic, and the shock-absorbing pad 4 is made of rubber. The side of the shock-absorbing pad 4 away from the push rod 5 is close to the housing on which this power-assisted handle is used, while the handle 3 is away from the housing on which this power-assisted handle is used. This avoids friction between the handle 3 and the door body on the housing during the opening and closing process, making the operation of the handle 3 smoother and greatly extending the service life of the door body. The connecting shaft 12 moves back and forth linearly on the inclined guide rail 13 on the handle base 1 through point contact with the handle base 1.

[0019] By modularizing the components of this power handle, component supply is successfully achieved, resulting in high manufacturing efficiency. The handle 3, in conjunction with the connecting shaft 12, increases the strength of the handle. The connecting shaft 12 makes point contact on the inclined guide rail 13 of the handle seat 1, reducing friction and making the use of this power handle smoother. Furthermore, since the handle seat 1, handle 3, lever 9, and push rod 5 are all made of plastic, the existing injection molding process can be used, further reducing component costs. On this basis, the thickness of this power handle can be further reduced without affecting the stability of use, thus meeting the requirements for use in thin doors in cabinets. The structure is ingenious and efficient, convenient and smooth to use, and has great application prospects.

[0020] Working principle: When the door of the box equipped with the power-assisted handle disclosed in this invention is opened, the lever 9 is actuated by the shaft 12 connected to the handle 3. The lever 9 will rotate on the handle seat 1. Since the other end of the lever 9 contacts the limiting block 8, and the limiting block 8 is connected to the push rod 5 through the first return spring 6, the limiting block 8 moves forward along the guide groove on the handle seat under the force of the lever 9. This process is described in detail below. Figure 3 As shown, the limiting block 8 pushes the push rod 5, and because the shock-absorbing pad 4 is installed on the push rod 5, the shock-absorbing pad 4 touches the box body equipped with the power-assisted handle disclosed in this invention under the force of the push rod 5, and pushes open the door of the box body under the reaction force, successfully realizing simple and smooth power-assisted door opening. After the door opening action is completed, the handle 3 and the push rod 5, the limiting block 8 and the lever 9 are reset by the second reset spring 11 and the first reset spring 6 respectively.

[0021] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
