Examples

As shown in fig. 1, this embodiment provides an eccentric key device, which mainly comprises a pressing key 2, a driving key 3, and a lever member 4, and the arrangement of the eccentric key device on a housing 1 can allow the pressing key 2 and an electronic key 5 inside the housing 1 to have a shift in position, so as to improve the degree of freedom and flexibility of key layout, and consider the design requirements of appearance and the design requirements of stacking elements in industrial design.

As shown in fig. 4, in order to ensure normal operation performance and good triggering feeling of the key, the pressing key 2 must be aligned with the center of the electronic key 5, but this also greatly limits the freedom of arrangement of the pressing key 2 and the electronic key 5. In the industrial design of the product, the appearance of the product is an important reference factor, so the position and the triggering direction of the pressing key 2 need to be coordinated with the style of the whole product to meet the requirements of the aesthetic and brand image of the user. On the other hand, in particular in some electronic products, in order to save space and achieve integration of functions, a stacked design of keys is necessary, and the positions and layout of the electronic keys 5 need to be carefully designed to ensure the spacing and operability between the individual electronic keys 5. Due to the various requirements for pressing the keys 2 and the electronic keys 5, conventional key designs often meet the requirements of both design and stacking.

In order to solve the above-mentioned problems, the present utility model introduces a driving key 3 on the basis of the conventional key design, the driving key 3 being disposed on the side of the pressing key 2 facing the inside of the housing 1 and being connected to the pressing key 2 through a lever member 4. The transmission key 3 is aligned with the center of the electronic key 5 for triggering the electronic key 5 through the lever member 4, thereby realizing an eccentric arrangement of the pressing key 2 and the electronic key 5.

In order to ensure that good triggering handfeel and feedback touch feel are also achieved under eccentric arrangement, the pressing key 2 is designed to be made of plastic materials with proper elasticity and touch feel, so that comfortable and stable pressing handfeel is provided; the transmission key 3 is made of silica gel material with soft, elastic and durable characteristics, and the tactile feedback is improved by the elasticity of the silica gel; the lever member 4 is designed to be a metal or plastic material having sufficient strength and stability to enhance the sensitivity of key actuation.

In this embodiment, as shown in fig. 2-3, the pressing key 2, the lever member 4 and the transmission key 3 are disposed in a vertical direction on the housing 1, a circuit board 7 is disposed inside the housing 1, an electronic key 5 is disposed on the circuit board 7, and a triggering direction of the electronic key 5 is oriented horizontally. Wherein, a part of the pressing button 2 is embedded into the shell 1, one end of the lever member 4 is propped against the embedded part of the pressing button 2, and the other end is connected with the transmission button 3. The transmission button 3 is towards the bellied convex surface in casing 1, and the convex surface is laminated mutually with electronic button 5, presses button 2 and is provided with boss 6 in the corresponding department of convex surface, and lever member 4 is located boss 6 with the junction of transmission button 3.

When the key device of this embodiment is used, force is applied to the pressing key 2 from top to bottom, and since the pressing key 2 is made of elastic plastic material, the force can be applied to the lever member 4 by the pressing key, so that the lever member 4 can tilt on the boss 6 with the joint of the lever member and the driving key 3 as a fulcrum, thereby driving the convex surface to displace toward the inside of the housing 1, and since the convex surface is attached to the electronic key 5, the electronic key 5 is triggered, and signals are transmitted to corresponding electronic equipment or systems to perform predetermined functions or operations.

Because the whole of this embodiment sets up vertically, realized from top to bottom pressing the transmission that changes into the horizontal direction for circuit board 7 and electronic button 5 can set up in the bottom of product, have reserved enough stacking design space between pressing button 2 and electronic button 5.

Finally, it is to be understood that the above embodiments are merely exemplary embodiments employed for the purpose of illustrating the principles of the present utility model, however, the present utility model is not limited thereto. Various modifications and improvements may be made by those skilled in the art without departing from the principles and spirit of the utility model, and such modifications and improvements are also considered within the scope of the utility model.
