Description

[Technical Field]

[0001] The present invention relates to a stand, and more particularly to a stand for a mobile device. [Background technology]

[0002] Currently, most stands for mobile devices on the market have a fixed tilt angle, and only a few products have the ability to adjust the tilt angle (see Figure 1).

[0003] 1 is a schematic diagram showing a commercially available mobile device holder 100. The foldable holder 100 has a plate 120 for attaching a mobile device 300, and a support member 140 connected to the upper edge of the plate 120 via a connecting portion 160. The support member 140 and the plate 120 form a foldable or unfoldable structure. In use, the support member 140 and the plate 120 are unfolded to a predetermined angle α, and the weight of the mobile device 300 is supported by the triangular structure formed by the bottom edge of the plate 120 or mobile device 300, the bottom edge of the support member 140, and the connecting portion 160. Summary of the Invention [Problem to be solved by the invention]

[0004] However, when using this foldable holder 100, the support member 140 must be perpendicular to the desk top 500; otherwise, the mobile device 300 cannot be stably supported. To provide a different tilt angle for the mobile device 300, the height H of the support member 140 must be adjusted. For example, in the product shown in FIG. 1 , the support member 140 itself is designed as a foldable plate, so to tilt the mobile device 300 further (i.e., to increase the angle α), the support member 140 must be folded to reduce the height H. Conversely, to decrease the angle α and place the mobile device 300 upright, the support member 140 must be unfolded to increase the height H.

[0005] In the design of FIG. 1 , the adjustable range of angle α of foldable holder 100 is limited by the variable height of support member 140. If the adjustable height range of support member 140 is too narrow, it is impossible to provide a larger or smaller angle α. Furthermore, because connector 160 does not have a function for fixing angle α, a stable angle must be maintained by the frictional force between the bottom of plate 120 or mobile device 300, and the bottom of support member 140 and the desk top 500. Therefore, support member 140 must remain perpendicular to desk top 500 and firmly support the mobile device. This design not only complicates the structure of support member 140, but also complicates the adjustment method. Furthermore, when folded by adhering it to plate 120, the overall thickness of stand 100 increases.

[0006] Therefore, the present inventors believed that the above drawbacks could be improved, and after extensive research, they came up with the present invention, which effectively improves the above issues through rational design.

[0007] The present invention has been made in view of the above circumstances, and aims to solve the above problems. That is, the object of the present invention is to provide a mobile device stand that has a simpler angle adjustment structure and adjustment method and also has a card clamp function. [Means for solving the problem]

[0008] To achieve the above object, one aspect of the present invention provides a mobile device stand comprising a card holder, a rotating shaft, and a plate base. The card holder has a card slot and a bottom edge corresponding to the card slot. A rotating shaft is installed at the bottom edge of the card holder. The plate base has a side edge connected to the rotating shaft, and the plate base and card holder are folded or unfolded via the rotating shaft. When the plate base and card holder are unfolded, the surface of the plate base is attached to a desk, forming an included angle between the card holder and the plate surface, and the angle of the included angle is adjusted and fixed by the rotating shaft.

[0009] According to one aspect of the present invention, the rotation axis is, for example, a torque hinge. The included angle between the card holder and the plate base has a specific angle range, and the rotation axis allows the card holder and the plate base to form a stable support structure within the specific angle range. The specific angle range is between 15° and 140°.

[0010] According to one aspect of the present invention, the included angle between the card holder and the plate base is selected from the range of 15° to 90° or 90° to 140°, specifically, 30°, 45°, 60°, 75°, 90°, 100°, 105°, 115°, 120°, 135°, or an angle range bounded by these angles.

[0011] According to one aspect of the present invention, when the included angle between the card holder and the plate base is less than 15°, the rotation axis accelerates the folding of the plate base and the card holder.

[0012] According to one aspect of the present invention, the card holder comprises a hard plate, a soft layer, and a magnetic material. The soft layer is smaller than the hard plate, and the edges of the soft layer are bonded to the edges of the hard plate, forming a card receiving space between the hard plate and the soft layer. The magnetic material and the soft layer are respectively installed on the front and back sides of the hard plate.

[0013] According to one aspect of the present invention, the soft layer has a cutout area, the shape and size of the cutout area are adapted to accommodate the plate base, and when the plate base and the card holder are folded together, the plate base is attached within the cutout area. [Effects of the Invention]

[0014] In summary, when the plate base and card holder of the stand of the present invention are unfolded, the angle between the card holder and the display surface can be adjusted and fixed by the rotation axis, and the card holder and plate base can form a stable support structure within a specific angle range.

[0015] At least the following points will become clear from the description and drawings to be described later. [Brief explanation of the drawings]

[0017] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. Furthermore, directional terms such as up, down, left, right, front, and rear used in the following examples are used merely to refer to the directions in the accompanying drawings. Therefore, these directional terms are used merely for explanation purposes and do not limit the present invention.

[0018] 2 is a schematic diagram of a mobile device stand according to an embodiment of the present invention, showing the rear structure when unfolded to stand on a desk. The stand 200 includes a card holder 220, a rotating shaft 240, and a plate base 260, and is suitable for placing a mobile device on it. The card holder 220 has a card insertion slot 221 and a base adjacent to the card insertion slot 221. The rotating shaft 240 is installed at the base and connected to one side of the plate base 260. The plate base 260 is folded or unfolded relative to the card holder 220 via the rotating shaft 240. When the plate base 260 and the card holder 220 are unfolded, the surface of the plate base 260 is attached to the desk top 500, and an included angle θ is formed between the card holder 220 and the surface. The included angle θ can be adjusted and fixed by the rotating shaft 240.

[0019] In one embodiment, the rotation shaft 240 is equipped with a torque hinge, for example, made of metal. When a force is applied to the card holder 220 and the plate base 260 to unfold them, the torque hinge generates a rotational frictional force, which acts as a resistance force to fix the unfolded included angle θ at any angle. In other words, when the plate base 260 is placed on the desk 500, the card holder 220 can be fixed in any position without the need for a separate support device. When a mobile device (not shown in FIG. 2) is placed on the card holder 220, the resistance force provided by the rotation shaft 240 is converted into the supporting force of the card holder 220 against the mobile device, and the included angle θ between the card holder 220 and the plate base 260 is stably maintained within a specific angle range, for example, 15° to 140°, so that the card holder 220 will not automatically collapse or tip over due to the weight of the mobile device. In this way, after the stand 200 and the mobile device are combined, the stand 200 can be firmly placed on the desk 500.

[0020] When the included angle θ between the card holder 220 and the plate base 260 is less than 15°, the plate base 260 and the card holder 220 can be folded quickly by the rotating shaft 240, thereby improving the folding efficiency and convenience of the stand 200.

[0021] FIG. 3 shows the front structure of the stand 200 when it is unfolded and placed upright on a desk 500. FIG. 4 is a schematic diagram showing the side of the stand 200. In the example of FIG. 3, the card holder 220 includes a hard plate 222, a soft layer 224, and magnetic materials 225 and 227. The soft layer 224 is, for example, a fabric layer, and its edges are joined to the left, right, and bottom edges of the back surface of the hard plate 222, with the upper edge left unjoined, forming a card insertion slot 221. A card storage space (not numbered) is formed between the hard plate 222 and the soft layer 224. The size of the soft layer 224 may be smaller than the size of the hard plate 222. The magnetic materials 225 and 227 are located on the front surface of the hard plate 222. That is, the magnetic materials 225 and 227 and the soft layer 224 are located on both the front and back surfaces of the hard plate 222, respectively.

[0022] For mobile devices that have their own magnetic material (not shown), the shape of the magnetic material 225 and 227 of the stand 200 is designed to match the magnetic material (not shown) already included in the mobile device. For mobile devices that do not have built-in magnetic material, the stand 200 of the present invention can be combined with an additional magnetic plate (not shown). By first attaching the additional magnetic plate to the back of the mobile device, the magnetic material of the stand 200 and the mobile device can be attracted to each other and used securely.

[0023] 5 is a perspective view illustrating the stand 200 in use when it is opened and the mobile device 300 is placed thereon. As shown in FIG. 5, the soft layer 224 has a cutout area 224A, the shape and size of which are adapted to accommodate the plate base 260. 6A to 6C respectively show side views in which the stand 200 supports the mobile device in different ways when the included angle θ is at different angles, for example, less than 90° and more than 90°.

[0024] 6A shows the state in which the stand 200 is opened, the plate base 260 is attached to the desk, and the mobile device 300 is placed on it. In this case, the bottom edge of the mobile device 300, the rotation axis 240 of the stand 200, and the surface of the plate base 260 are simultaneously in contact with the desk, forming a solid support structure. Therefore, the included angle θ in this situation is within the range of 15° to less than 90°, such as 30°, 45°, 60°, 75°, or any angle range encompassing the above angles, all of which are within the applicable range.

[0025] 6B, the included angle θ of the stand 200 can be in the range of 90° to 140°, for example, 100°, 105°, 115°, 120°, 135°, or an angle range defined by these angles. If the included angle θ is greater than 90°, the card holder 220 is moved slightly upward on the back of the mobile device 300 and attached to the appropriate position. At this time, the rotation axis 240 of the stand 200 moves slightly upward and does not contact the desk 500; only the bottom edge of the mobile device 300 and the side edge of the plate base 260 opposite the rotation axis 240 contact the desk 500 to provide support.

[0026] As shown in FIG. 6C , the card holder 220 of the stand 200 does not need to be completely attached to the back of the mobile device 300. The mobile device 300 typically has a lens (not shown) for photography on its back, which is generally surrounded by a flange 320. When using the stand 200, only the upper edge of the card holder 220 abuts against the lower edge of the flange 320, and by setting an appropriate included angle θ, the stand 200 can be stably placed on a desk 500, as shown in FIG. 6C . In this case, the plate base 260 and the rotation shaft 240 of the stand 200 are attached to the desk 500, but the rotation shaft 240 and the bottom edge of the mobile device 300 are separated. In this way, the stand 200 of the present invention can stably place the mobile device 300 and adjust its tilt angle without relying on a magnetic material.

[0027] A folded perspective view is shown in Figure 7. When the plate base 260 and the card holder 220 are folded together, the plate base 260 is stuck together within the cutout area 224A, making the whole structure more compact and convenient for storage and portability.

[0028] In summary, the basic structure of the stand according to the present invention comprises at least a card holder, a rotating shaft, and a plate base. The rotating shaft is connected between the card holder and the plate base. The plate base and the card holder are folded or unfolded via the rotating shaft. When the plate base and the card holder are unfolded, the card holder and the display surface form an included angle, and the angle is adjusted and fixed by the rotating shaft. The included angle has a specific angle range between 15° and 140°, and the card holder and the plate base form a stable support structure within the specific angle range.

[0029] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the description of the scope of the utility model registration claims that such modifications and improvements can also be included in the technical scope of the present invention.
