Description

Joint module

The present invention relates to a joint module, and more particularly to a joint module having a better joint strength.

At present, consumer electronics products tend to be thin and multi-directional. In terms of thin design, the thickness and size of the internal electronic components, mechanism structure and outer casing are usually reduced to reduce the thickness of the product. However, the problem that comes with it is that as the thickness of the product shrinks, the overall structural rigidity also declines, which not only affects the reliability of the product, but also reduces the strength and life of the product.

A common solution is to replace the plastic material with the structure or outer casing of the product by metal or carbon fiber to increase the rigidity, but the replacement material must face the problems of increased cost, heavy weight, and blocked antenna reception.

The multi-design is to design the original single-function product design into a multi-functional one. For example, when the tablet is connected to the keyboard, it can be used as a notebook computer. When the combination of thin and light design is adopted, a new problem is encountered in that the two shells cannot be accurately aligned when they are horizontally docked, and the deformation warpage is likely to occur due to insufficient strength at the joint.

The invention provides a joint module, which can effectively improve and strengthen the rigidity of the joint when the two shells are horizontally butted.

The invention provides a joint module comprising a first casing and a second casing. The first housing includes a first body, a receiving slot, a track and a Pushing pieces.

The track is connected to the accommodating groove, and the depth of the track along one axial direction is greater than the depth of the accommodating groove along the axial direction. The pushing member is fixed to the receiving groove. The second housing includes a second body, a linkage, a link and an engagement arm. The connecting rod is pivotally connected to the second body and the connecting rod includes a first end and a second end. The first end of the connecting rod is pivotally connected to the linking member, and the second end of the connecting rod is pivotally connected to the engaging arm. When a part of the second housing extends axially into the receiving groove of the first housing, the pushing member of the first housing pushes the linking member, and the connecting rod rotates correspondingly to drive the engaging arm into the first housing. Inside the track.

The above described features and advantages of the present invention will be more apparent from the following description.

Since the rotation angles of the first end 223a and the second end 223c are the same when the connecting rod 223 rotates, the distance between the pivoting portion 223e of the connecting rod 223 and the first end 223a and the second end 223c is the first end of the connecting rod 223. The main reason for the rotation path of 223a and second end 223c. That is, when the link 223 is rotated, the path length of the second end 223c is twice the path length of the first end 223a.

In this way, the length of the path taken by the engaging arm (not shown) by the connecting rod is greater than the length of the path taken by the linking member (not shown). The engagement arm can extend deeper into the first housing (not shown) to increase the joint strength. In addition, in order to enable the linkage to drive the link 223 and interlock the engagement arm, the shape of the opening 223d is longer than the opening 123d to provide a pivot for the engagement arm to be movable and rotated in the opening 223d, and due to the pivot portion 223e and The distance of the first end 223a of the link 223 is short, and the length of the opening 223b can be shortened with respect to the opening 123b.

Returning to the embodiment of FIG. 1A , after a portion of the second housing 120 and the engagement arm 124 are inserted into the first housing 110 , the second housing 120 is also required to be fixed to the first housing 110 .
