In the following embodiments, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or sequence.

[0037] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0038] The present application provides a linkage mechanism for synchronous linear motion, including a driving unit 100, a first linear motion component 200, a second linear motion component 300, a first device, a second device, and a transmission component 400. The driving unit 100 is used to provide the driving force for linear motion. The first linear motion component 200 is connected to the first device, and the power output end of the driving unit 100 is connected to the first linear motion component 200. The driving unit 100 is used to drive the first linear motion component 200 to move, so as to drive the first device to perform linear reciprocating motion. One end of the transmission component 400 is connected to the first linear motion component 200, the second linear motion component 300 is connected to the second device, and the other end of the transmission component 400 is connected to the second linear motion component 300. Thus, the driving unit 100 drives the first linear motion component 200 to move, the first linear motion component 200 drives the first device to perform linear reciprocating motion, the first linear motion component 200 drives the second linear motion component 300 to move synchronously through the transmission component 400, the second linear motion component 300 drives the second device to perform linear reciprocating motion, and the motion paths of the first device and the second device are parallel and in the same or opposite directions.

[0039] Specifically, a driving force is provided by the same driving unit 100. First, the first linear motion assembly 200 is driven to move, and then the power is transmitted to the second linear motion assembly 300 through the transmission assembly 400, driving the second linear motion assembly 300 to move synchronously. This realizes the synchronous linear motion in the same or opposite directions of the first device arranged on the first linear motion assembly 200 and the second device arranged on the second linear motion assembly 300, achieving the function of driving two assemblies to move with a single drive, reducing the equipment cost, simplifying the equipment structure and control method, and solving the problems of complex motor electronic control solutions and high difficulty in achieving synchronous accuracy.

[0040] Furthermore, the first linear motion assembly 200 and the second linear motion assembly 300 can be set according to actual equipment requirements to make the first device and the second device move in the same direction or in the opposite direction. For example, in an X-ray imaging device, the X-ray tube and the detector need to be synchronously linked and move in the same direction to better obtain data such as the density of human tissues. In addition, for an automatic door, it needs to move synchronously in the opposite direction, and the combination form of the single drive and the transmission mechanism of the present application can be adopted to achieve this.
