Description

Technical Field

[0001] The utility model relates to the field of door handles, in particular to an adjustable door handle. Background Art

[0002] A door handle is a device used to open and close doors, usually made of metal, plastic or other durable materials. Its design is not only functional, but also often matches the overall style of the door and the architectural environment. There are many types and styles of door handles, which can be classified according to their installation location, operation method and design style.

[0003] The choice of door handles should be based on the function of the door, the overall style of the building and personal preferences, but there are still some problems: 1) The internal structure strength of some door locks is relatively high, and a large force is required to turn the door handle when opening, which will result in a poor user experience; 2) For some young children and users with myasthenia-type physical diseases, the turning force of the door handle is more troublesome for these people; therefore, in view of the above situation, there is an urgent need to develop an adjustable door handle to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable door handle to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An adjustable door handle comprises a handle, a shell and a rotating shaft, wherein the rotating shaft is horizontally installed at the edge of the handle, one end of the rotating shaft is arranged through the middle position of the side wall of the shell and is rotatably connected to the shell, and a power assist component is installed on the inner wall of the shell;

[0007] The power assist assembly includes a motor, a gear box and an electronic control unit. The gear box is vertically embedded in the inner wall of the outer shell and fixedly connected to the outer shell by screws. The motor is horizontally installed on one side of the gear box. The gear box is drive-connected to the motor. The electronic control unit is vertically installed on the inner wall of the outer shell. The motor and the electronic control unit are electrically connected.

[0008] As a further solution of the utility model: a bevel gear A is nested and installed in the middle position of the rotating shaft, and a trigger rod arranged horizontally is welded to the end side wall of the rotating shaft.

[0009] As a further solution of the utility model: a horizontally arranged bevel gear B is provided at the bottom of the gear box, the bevel gear B is nested in the middle section of the rotating shaft and achieves a clearance fit with the rotating shaft, the bevel gear B is connected to the internal gear of the gear box, and the bevel gear B is used for transmission between the gear box and the bevel gear A.

[0010] As a further solution of the utility model: the bevel gear A is meshed with the bevel gear B, which plays a transmission effect between the power-assisting component and the rotating shaft.

[0011] As a further solution of the utility model: a contact sensor is installed at the bottom of the electronic control unit, and the top edge of the trigger rod is in contact with the contact sensor. The contact sensor can detect whether the trigger rod is displaced, and thus feedback a signal to the electronic control unit when it is displaced.

[0012] Beneficial effects: This type of adjustable door handle is equipped with a power-assisting component inside to assist the user in turning the door handle. When the door handle drives the rotating shaft to rotate, the electronic control unit is triggered, and then the motor and gear box are started to assist the rotating shaft, thereby reducing the force required to turn the door handle. This design will greatly enhance the user experience. At the same time, it can be of great help to some young children and users with myasthenia gravis-type physical diseases.

[0019] Example

[0020] See also Figures 1 to 5 In an embodiment of the utility model, an adjustable door handle comprises a handle 1, a shell 2 and a rotating shaft 3, wherein the rotating shaft 3 is horizontally installed at the edge of the handle 1, one end of the rotating shaft 3 is arranged through the middle position of the side wall of the shell 2 and is rotatably connected to the shell 2, and a power assist component 4 is installed on the inner wall of the shell 2;

[0021] The power assist assembly 4 includes a motor 41, a gear box 42 and an electronic control unit 43. The gear box 42 is vertically embedded in the inner wall of the outer shell 2 and fixedly connected to the outer shell 2 by screws. The motor 41 is horizontally installed on one side of the gear box 42. The gear box 42 is drive-connected to the motor 41. The electronic control unit 43 is vertically installed on the inner wall of the outer shell 2. The motor 41 and the electronic control unit 43 are electrically connected.

[0022] As a further solution of the utility model: a bevel gear A31 is nested and installed in the middle position of the rotating shaft 3, and a trigger rod 32 arranged horizontally is welded to the end side wall of the rotating shaft 3.

[0023] As a further solution of the utility model: a horizontally arranged bevel gear B421 is provided at the bottom of the gear box 42, the bevel gear B421 is nested in the middle section of the rotating shaft 3, and a clearance fit is achieved between the rotating shaft 3, the bevel gear B421 is connected to the internal gear transmission of the gear box 42, and the bevel gear B421 is used for transmission between the gear box 42 and the bevel gear A31.

[0024] As a further solution of the utility model: the bevel gear A31 is meshed with the bevel gear B421 to play a transmission effect between the power assist assembly 4 and the rotating shaft 3.

[0025] As a further solution of the utility model: a contact sensor 431 is installed at the bottom of the electronic control unit 43, and the top edge of the trigger rod 32 is in contact with the contact sensor 431. The contact sensor 431 can detect whether the trigger rod 32 is displaced, and thus feedback a signal to the electronic control unit 43 when it is displaced.

[0026] The working principle of the utility model is: when the adjustable door handle is in use, the user holds the handle 1 and turns it clockwise. When the handle 1 is slightly turned by a certain angle, the trigger rod 32 is driven by the rotating shaft 3 to trigger the contact sensor 431.
