Description

BACKGROUND

[0001] The present disclosure relates to a connecting device and an electronic device with such a device, and in particular to a connecting device that can prevent material of its enclosing mechanism from producing creases or traces of manipulation when a curvature occurs.

[0002] Existing electronic devices, such as laptop computers and panel computers, are typically divided into two parts: the display and the host computer. The display can rotate freely around the host computer and remain in any position. It is usually connected to the host computer by a hinge. To maintain an aesthetically pleasing appearance, some electronic devices use encapsulating materials to shield the hinge point, thus protecting it, for example, the hinge connector, from damage and preventing it from affecting the overall appearance of the electronic device.

[0003] The encapsulating material used would rotate with the display during rotation, entering various states in which the material is unlikely to be perfectly tight at the pivot point. If the material is not properly seated at the pivot point, inward creases can occur, thus affecting the aesthetic appearance.

[0004] If, as in Fig. 1 and Fig. As shown in Figure 2, if existing electronic devices are closed, causing the display and keyboard to lie parallel to each other, creases would form in the casing material that encases the rotating mechanism on the inside. 2 appear. SUMMARY

[0005] The present disclosure provides a connecting device which overcomes the aforementioned defects according to the prior art by using the connecting device regardless of where the rotary mechanism is turned, wherein the covering mechanism comprising the outside of the rotary mechanism is attached to the rotary mechanism without any creases or traces of manipulation.

[0006] The technical solution for the connecting device according to the present disclosure is a connecting device for a rotating connection between a first body and a second body, wherein the connecting device comprises a rotating mechanism for a rotating connection of the first body and second body, wherein the connecting device further comprises a covering mechanism for covering at least a part of the rotating mechanism, wherein the covering mechanism is attached to the first body and second body and a degree of tightness of the covering mechanism varies with the rotation of the covering mechanism.

[0024] The following is a detailed introduction regarding the connecting device and the electronic device according to the embodiment of the present disclosure in conjunction with Fig. 3– Fig. 8.

[0025] Please note that in the disclosure, in all its embodiments, the word "envelop" or "enveloping" can be understood as "cover" or "covering." "Envelop" means "to cover and fit."

[0026] Fig. 3 and Fig. 4 show the electronic device 1 according to the present disclosure. From Fig. 3 and Fig. 4 it is clearly evident that when using the connecting device according to the present disclosure, when the first body5 and the second body 6 of the electronic device 1 The two parts are closed and opposite each other; the encasing mechanism forms no folds, while the rotating mechanism, enclosed by the encasing mechanism, rotates. The encasing mechanism always sits tightly against the rotating mechanism. 9 .

[0027] Fig. 3– Fig. Figure 6 shows a connecting device for a rotatable connection of a first body 5 and a second body 6 , wherein the connecting device has a rotary mechanism 9 for the rotating connection of the first body 5 and the second body 6 comprising, wherein the connecting device further comprises a covering mechanism for enclosing and covering the rotary mechanism, the covering mechanism being located on the first body 5 or second body 6It is attached, and the tightness of the wrapping mechanism varies with the rotation of the rotating mechanism. The wrapping mechanism comprises a first wrapping part. 3 , which is the first side of the rotating mechanism 9 enveloped, i.e., the left side of Fig. 4 and Fig. 5, and with a rotating rotary mechanism 9 The connecting device has a first state in which the first side of the rotary mechanism lies within the angle of intersection between the first body and the second body (in the first state the first body is located 5 and the second body 6 at any position, from the closed state, as in Fig. 3 shown, up to an open one with a cutting angle of 180°, as in Fig. 6 shown), and a second state in which the first side of the rotation mechanism lies outside the angle of intersection between the first body and the second body (in the second state the first body is located 5 and the second body 6 at any position, from opening with a cutting angle of 180°, as in Fig. 6 shown, downwards to the position where a maximum cutting angle is achieved by rotating the first body 5 and the second body 6 can be achieved).

[0028] When the connecting device is in the first state, the degree of tightness of the first encasing part is 3 looser than the tightness of the first wrapping part 3 , when the connecting device is in the second state, since, when the first enclosing part 3In its first state, its expansion range is small, so that it is always attached to the rotating mechanism, making its degree of tightness adjustable.

[0030] When the connecting device is in the first state, the second sheathing part has a third degree of tightness; when the connecting device is in the second state, the second sheathing part has a fourth degree of tightness, the third degree of tightness being due to the fact that when the second sheathing part 4 in the first state, its expansion range is larger so that it can always sit on the rotating mechanism, it is tighter than the fourth tightness level, making its tightness level adjustable.

[0031] To adapt to a different degree of tightness, the sheathing mechanism is pre-stretched before attachment to the first and second bodies, so that it has a preset degree of tightness, so that in the state that is in Fig. Figure 5 shows the first part of the casing. 3 would show no wrinkles or signs of manipulation.

[0032] The first and second encapsulation parts must be pre-stretched to a certain value during the assembly process, where the theoretical strain value is L = L1 – πR1; however, it is ensured that the actual strain value has its variation Δ according to different strain materials: πR2 < Δ < πR1. Where: R1 = Minimum radius; R2 = Maximum radius; L1 = the dimension of the material stretched to 180°; L = elongation value (see Fig. 5 and Fig. 6)

[0033] In general, the material for the encapsulation mechanism is silica gel, ensuring that the encapsulation mechanism is stretchable and has a certain degree of elasticity and flexibility.
