Detailed Description

In order to make those skilled in the art better understand the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments, not all embodiments, of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the embodiments of the present invention.

The terms "comprises," "comprising," and any other variation thereof in the description and claims of embodiments of the present invention and the above-described drawings are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1 to 5, an embodiment of the present invention provides a hinge cover 1, which can be applied to an electronic device including a first component unit 2 and a second component unit (not shown) connected by a hinge.

Specifically, as shown in fig. 1 to 3, the shaft cover 1 includes an outer frame 3 and an inner frame 4 made of different materials, the outer frame 3 covers the inner frame 4, the inner frame 4 provides an inner cavity for accommodating the shaft, and the inner frame 4 is provided with a buckle 5 for being buckled with the first component unit 2.

Different from the traditional rotating shaft cover 1 made of pure hardware or pure plastic materials, the rotating shaft cover 1 provided by the embodiment of the invention is made of two different materials, namely, the outer frame 3 and the inner frame 4 are respectively made of different materials, and the whole rotating shaft cover is of a composite material structure. Therefore, the complementary effect can be achieved, and the advantages of all materials (such as fine structure like good appearance quality and easy processing of the buckle 5) can be fully exerted, so as to overcome the defects of other materials.

In an alternative embodiment, the outer frame 3 can be made of a material with good appearance quality, such as hardware, ceramic, wood, glass or a super fiber material, so as to meet the high requirement of the electronic device on appearance beauty; simultaneously, the material of meticulous complex construction such as easy processing buckle 5 can be selected to use to inside casing 4 and is made, for example partial metal such as aluminium or plastic to reduce the processing degree of difficulty, promote machining efficiency when guaranteeing the equipment reliability. Therefore, the manufactured rotating shaft cover 1 can meet the requirement of good appearance quality, and can be simply and efficiently processed to obtain the structure of the buckle 5 which is buckled and connected with other units.

It will be appreciated that the material composition of the outer frame 3 and the inner frame 4 may take any number of forms, such as: the frame 3 of plastic material and the inside casing 4 combination of metal material, the frame 3 of ceramic material and the inside casing 4 combination of plastic material, the frame 3 of ceramic material and the inside casing 4 combination of metal material, the frame 3 of glass material and the inside casing 4 combination of plastic material. In practical application, the specific compounding mode can be determined by combining the performance advantages and disadvantages of various materials and the requirements under the current application scene.

At present, compared with the plastic material, the appearance quality of the metal material is generally better than that of the plastic material, and the processing difficulty and cost of the metal material are higher than those of the plastic material, so the embodiment of the invention can select the combination mode of the outer frame 3 made of the metal material and the inner frame 4 made of the plastic material. However, with the technical development in the material field, there may be advantages that a part of metal may also have processing difficulty and cost reduction in the future, or plastic may also exhibit good appearance quality, and therefore, the material compounding manner of the outer frame 3 and the inner frame 4 is not limited in the embodiment of the present invention.

The outer frame 3 and the inner frame 4 of the shaft cover 1 may be connected by bonding, and the outer surface of the inner frame 4 and/or the inner surface of the outer frame 3 are/is coated with adhesive, and then the outer frame 3 and the inner frame 4 are aligned and bonded. Of course, the bonding method is only a simple and low-cost implementation method, and other connection methods, such as a fastening method, may be actually adopted.

Because the inner chamber that the pivot lid 1 provided need be used for installing pivot, circuit etc. consequently for rationalizing the utilization space, the inner frame 4 is preferred to be consistent with the overall structure of outer frame 3, for example both are U type structure to avoid producing great space between the two, consume more installation space.

For example, as shown in fig. 4, the outer frame 3 and the inner frame 4 are both asymmetric U-shaped structures; and/or the same ridge line 7 is formed on the same single side position of the outer frame 3 and the inner frame 4 respectively in an extending way along the length direction of the rotating shaft. This asymmetric U type structural design and crest line 7 design have the function of preventing staying. When the inner frame 4 and the outer frame 3 are reversely assembled, the fool-proof design can prevent the inner frame 4 from being completely assembled into the outer frame 3, so that the production line operation is greatly facilitated, and the product yield is improved.

In order to avoid deformation and even damage of the outer frame 3/the inner frame 4 caused by mutual contact and extrusion of the outer frame 3 and the inner frame 4 in the assembling process and the using process, a certain mounting gap can be designed between the outer frame 3 and the inner frame 4 in the embodiment of the invention, for example, the mounting gap is 3mm, and the outer frame 3 and the inner frame 4 are well protected.

Meanwhile, the contact surface of the outer frame 3 with the first constituent unit 2 is provided with a chamfer such as a C-angle of 0.3. Therefore, in the practical production and use, the problem of hand scraping caused by the step difference caused by the deviation of the rotating shaft cover 1 can be avoided.

Referring to fig. 3, the number of the fasteners 5 on the inner frame 4 is designed to be plural, and the fasteners are sequentially arranged at intervals along the length direction of the rotating shaft, so as to ensure the connection reliability between the rotating shaft cover 1 and the first component unit 2 of the electronic device.

The inner frame 4 is further provided with a plurality of hollow structures 6 and positioning holes along the length direction of the rotating shaft, so that the buckling operation of the rotating shaft cover 1 and the first component unit 2 of the electronic equipment is facilitated. In the subsequent assembly process of the shaft cover 1 and the first assembly unit 2, the positioning hole is convenient for the binding jig to accurately position the shaft cover 1; and hollow out construction 6, can be convenient for bind the operation of tool, reduce and interfere.

Referring to fig. 5, an embodiment of the present invention further provides an electronic device, including a first component unit 2 and a second component unit rotatably connected via a rotating shaft, and further including the above rotating shaft cover 1, wherein the rotating shaft is installed in an inner cavity provided by the rotating shaft cover 1, and a buckle 5 on the rotating shaft cover 1 is buckled with a buckle position on the first component unit 2. Since the electronic device includes the above-mentioned shaft cover 1, the electronic device provided by the embodiment of the invention also has the same advantages as the above-mentioned shaft cover 1, and the details are not described here.

In order to further improve the appearance quality, the material of the outer frame 3 can be selected to be the same as the material of the shell of the first component unit 2, so that the consistency of the appearance effect of the shell of the electronic device can be ensured.

Specifically, the electronic device may be a notebook computer, and the first component unit 2 may be a display module and the second component unit may be a host module. In addition, the electronic device may also be any other device having two parts movably connected through a rotating shaft, which is not limited in the present invention.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
