Motor elastic structure capable for allowing linear motor to vibrate along X or Z axis

Abstract

The invention belongs to the technical field of a linear motor, and particularly relates to a motor elastic structure capable of allowing a linear motor to vibrate along an X or Z axis. The motor elastic structure comprises a motor shell, a vibration mass block and curved elastic sheets, wherein the vibration mass block is arranged in the motor shell, the curved elastic sheets are arranged at a left side and a right side of the vibration mass block, each curved elastic sheet comprises an upper bending part and a lower bending part, the upper bending part is provided with an upper outer end, the upper outer end is connected with the vibration mass block, the lower bending part is connected with a lower outer end, the lower outer end is connected with the motor shell, the upper bending part and the lower bending part are connected by respective upper inner end and lower inner end, a plane where the curvature radius of the lower bending part is located is parallel to the Z axis, and an included angle between planes where the curvature radiuses of the upper bending part and the lower bending part are located is 5-175 degrees, preferably 60-120 degrees, and more preferably 90 degrees, so that vibration sensing can be respectively provided for the linear motor in an X-axis direction or a Z-axis direction, the number of the linear motors is reduced, the production cost is reduced, the internal space of a communication terminal is saved, and the weight is reduced.

Description

technical field [0001] The invention belongs to the technical field of linear motors, and in particular relates to a motor elastic structure capable of vibrating a linear motor along an X-axis or a Z-axis. Background technique [0002] Linear motors are mainly used in communication terminals such as mobile phones, tablet computers, and wearable devices, as well as game controllers, toys, and other devices. They are popular for their advantages such as fast response, high vibration, small size, and easy installation. However, as communication terminal devices such as mobile phones and tablet computers become thinner, smaller, and lighter in weight, the requirements for the space occupied by linear motors are getting higher and higher. Generally speaking, linear motors The smaller the volume, the better. However, the available linear motors on the market can only provide vibration in one direction, such as vibration along the X axis, such as figure 1 As shown, the vibrating ...

Problems solved by technology

However, the available linear motors on the market can only provide vibration in one direction, such as vibration along the X axis, such as figure 1 As shown, the vibrating mass 2 installed in the motor housing 1 can vibrate left and right along the X axis, but when the vibrating mass needs to vibrate along the Z axis so that the linear motor provides up and down vibration, the vibrating mass vibrates up and down under the action of the driving force , the fixed springs 4 arranged on the left and right sides will be subjected to a large torque in the Z-axis direction to limit the up and down vibration of the vibrating mass. On the one hand, the vibration feeling generated is not strong and impractical; Shorten the service life of the linear motor, so only one more linear motor can be installed to provide vibration in the Z-axis direction, but this not only increases the internal space of the mobile phone or tablet occupied by the linear motor, but also increases the production cost
