Description

Technical Field

[0001] The present invention relates to a support for placing a mobile device, and particularly to a stand for a portable mobile device.

Background Art

[0002] With the popularization of mobile devices, when users view video content, conduct video calls, or operate applications, it is required to support the mobile device with a stand for the mobile device and maintain the mobile device at an appropriate position and angle. As such stands for mobile devices, various commercially available products such as desktop stands, clamping stands, and magnetic attraction stands are provided, which satisfy certain needs.

[0003] However, conventional stands for mobile devices have the following problems. (1) Many stand structures lack flexibility or have only a single rotation axis, so the adjustment angle of the mobile device is limited and it is difficult to adapt to different usage scenarios; (2) Some stands are large in volume or have a large thickness even after folding, so they are inferior in portability; (3) The fixing method is often limited to a single form. For example, it can only be installed on a flat surface or can only be clamped to an object, and the freedom of use is not sufficient.

[0004] In addition, in some conventional stands, although they have a multi-stage rotation structure, their structure is complex and their operability is poor, or sufficient stability cannot be obtained after adjustment, and there is a risk of angular deviation due to external force or vibration, which may affect the usability. Therefore, providing a stand for a mobile device that combines simplicity of structure and stability, has high portability and multi-angle adjustment capabilities, and is further applicable to multiple fixing methods has become an important issue to be solved in this technical field.

[0019] The following will be described in detail in conjunction with specific examples and drawings for an easy understanding of the embodiments of the present invention. When an element is referred to as being "attached or fixed to" another element, it can be understood that it may be directly present on the other element or there may be an element in the middle between them.

[0020] In the examples shown in this specification, directions such as "up", "down", "left", "right", "front", "rear", etc. are for explaining the relative positional relationships of the structures and movements of each member in the present application. When the members to be described are in the positions shown in the drawings, the descriptions of these directions are appropriate. However, when the absolute positions of the members to be described change, it is understood that the relative positional relationships also change accordingly.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in this specification are only for explaining specific examples and do not limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0022] As shown in FIGS. 1 and 2, each is a perspective view of the folded state and the deployed and used state in Embodiment 1 of the present invention. The stand for a portable mobile device according to the present invention mainly aims to solve the problems that in a conventional stand for a mobile device, it is difficult to fold and store, has poor portability, and has limitations in the adjustment angle and the fixing method.

[0023] The portable mobile device stand according to this invention includes a mounting unit 10, a first support unit 20, a second support unit 30, and a base unit 40. The mounting unit 10 is used to fix the mobile device, the first support unit 20 is pivotally attached to the mounting unit 10, the second support unit 30 is pivotally connected to the first support unit 20 and is rotatable around the same axis as the first support unit 20, and the second support unit 30 is pivotally attached to the base unit 40. Due to the above multi-axial rotation connection, the mobile device can be adjusted in multiple directions and angles, thereby significantly improving the adaptability of the mobile device stand to different usage scenarios.

[0024] Specifically, the mounting unit 10 has a protruding first pivot base 11, and the mounting unit 10 is rotatable relative to the first support unit 20 by pivoting the first support unit 20 to the first pivot base 11. The second support unit 30 is connected to the first support unit 20 so as to be rotatable around the same axis via a connecting surface between the two. The base unit 40 has a protruding second pivot base 41, and the base unit 40 is rotatable relative to the second support unit 30 by pivoting the second support unit 30 to the second pivot base 41.

[0025] In the folded state, the first support unit 20 and the second support unit 30 can be positioned between the first pivot base 11 and the second pivot base 41, and the mounting unit 10, the first support unit 20 and the second support unit 30, and the base unit 40 form a three-layer laminated structure. This effectively reduces the overall height and volume after folding, resulting in improved portability and storage efficiency, making it particularly suitable for outdoor activities and mobile use.

[0026] The base unit 40 is provided with a fixed clamping member 42, a movable clamping member 43, and at least one elastic member 44 at one end away from the second pivot base 41. As shown in Figure 4, the elastic member 44 is installed inside the base unit 40 and is configured to bias the movable clamping member 43 toward the fixed clamping member 42. The movable clamping member 43 is also provided with an operating ring 45, and by operating the operating ring 45, the user can move the movable clamping member 43 synchronously, forming another clamping and fixing means for the base unit 40.

[0027] In use, the mobile device is fixed to the mounting unit 10 and directly mounted on a flat surface by the base unit 40, or is configured to be clamped to different fixed objects by the fixed clamping member 42 and the movable clamping member 43. The user can adjust the height, tilt, and orientation of the mobile device according to their actual needs through the relative rotational relationship of the first support unit 20, the second support unit 30, and the base unit 40, thereby achieving an optimal viewing or operating position and improving comfort and practicality of use.

[0028] The mounting unit 10 secures the mobile device using a magnetic attraction method and includes a device magnetic attraction area 12. At least one magnet 13 is embedded in the device magnetic attraction area 12, allowing the mobile device to be quickly and stably attracted to the mounting unit 10. The magnetic attraction fixing method not only reduces the time required to attach and detach the mobile device, but also avoids problems such as damage to the main body and limitations in size compatibility caused by conventional clamping structures. Furthermore, by providing a shielding material inside the mounting unit 10, the magnetic force is mainly concentrated on the side of the device magnetic attraction area 12, and the magnetic force on the back side is significantly reduced. This suppresses the influence of magnetic force on the rotation of the rear structure and improves the smoothness and stability of rotation adjustment.

[0029] As shown in Figure 3, a positioning structure and a connection structure are provided in the connection area between the first support unit 20 and the second support unit 30. The positioning structure includes a plurality of positioning protrusions 21 formed on the connection surface of the first support unit 20 and distributed at equal angles, and a plurality of positioning grooves 31 formed on the connection surface of the second support unit 30. When the first support unit 20 and the second support unit 30 are rotated to a specific angle, the positioning protrusions 21 are positioned within the positioning grooves 31, thereby temporarily positioning them and preventing angular displacement due to vibration or external force during use of the mobile device, thereby improving support stability.

[0030] The connection structure further includes a convex shaft 22 provided in the first support unit 20, a shaft hole 32 provided in the second support unit 30, a spring 33, and a bolt 34. When the convex shaft 22 is inserted into the shaft hole 32, the spring 33 is inserted from the other end of the second support unit 30 and fitted onto the outer circumference of the convex shaft 22, and fastened by the bolt 34. This configuration allows the first support unit 20 and the second support unit 30 to rotate around the same axis and to allow minute displacements in the axial direction, thereby achieving both smooth rotation and structural strength.

[0031] The second support unit 30 is pivotally attached to the base unit 40, and the pivot point is located away from the connection side between the second support unit 30 and the first support unit 20. The base unit 40 has a protruding second pivot base 41, and the second support unit 30 is pivotally attached to the second pivot base 41. The fixing clamping member 42 and the second pivot base 41 both protrude from the same side surface of the base unit 40 and are located at opposite ends.

[0032] As a result, in the folded state, the mounting unit 10, the first support unit 20, and the second support unit 30 can be positioned between the fixing clamping member 42 and the second pivot base 41, and a three-layer laminated structure is formed by the mounting unit 10, the first support unit 20, the second support unit 30, and the base unit 40. This effectively reduces the overall height after folding.

[0033] As shown in Figure 4, the base unit 40 is provided with the fixed clamping member 42, the movable clamping member 43, and at least one of the elastic members 44 at one end away from the second pivot base 41. The fixed clamping member 42 is erected on the surface of the base unit 40, and the movable clamping member 43 is L-shaped, with a portion extending into the interior of the base unit 40 and configured to be biased in a direction away from the fixed clamping member 42 along the linear direction. The elastic member 44 is, for example, a spring, installed inside the base unit 40, and in contact with the movable clamping member 43. When no external force is applied, the elastic member 44 biases the movable clamping member 43 toward the fixed clamping member 42, maintaining the fastening strength in the clamped state. The interior of the main body of the movable clamping member 43 is composed of an L-shaped metal piece 431. This L-shaped metal piece 431 not only improves the structural rigidity but also increases the weight of the base unit 40, thereby enhancing stability when placed on a desk.

[0034] In this embodiment, the operating ring 45 is pivotally attached to the movable clamping member 43, with the pivot point located on the opposite side of the movable clamping member 43 from the fixed clamping member 42. By operating the operating ring 45, the user can move the movable clamping member 43 away from the fixed clamping member 42, thereby clamping the object to be fixed by the fixed clamping member 42 and the movable clamping member 43. After the external force is removed, the movable clamping member 43 is biased toward the fixed clamping member 42 by the restoring force of the elastic member 44, thereby maintaining the normal clamping force.

[0035] Furthermore, in this embodiment, the operating ring 45 has an annular structure that can be opened and closed, and includes a first arc-shaped member 451 and a second arc-shaped member 452 pivotally attached to the first arc-shaped member 451, with a torsion spring provided at the pivot point. The first arc-shaped member 451 and the second arc-shaped member 452 rotate until they connect to each other, forming a closed annular structure, and by pressing the second arc-shaped member 452 to open it, it can be attached to a ring on a backpack or other equipment, thereby improving portability.

[0036] A position limiting base 432 is provided on the movable clamping member 43 on the side of the operating ring 45, and the shape of the position limiting base 432 corresponds to the outer shape of the operating ring 45. The operating ring 45 is rotated and fitted onto the outer circumference of the position limiting base 432, thereby temporarily fixing it in that position, making it easy to store and saving space. When the operating ring 45 is pressed with an external force greater than a predetermined amount during use, the operating ring 45 is configured to protrude from the surface of the movable clamping member 43. In addition, a screw hole 433 is provided at an intermediate position of the position limiting base 432, and the screw hole 433 can be screwed into a fastening bolt provided in the center of the platform of the camera tripod. This provides an alternative form of use.

[0037] As shown in Figure 5, the base unit 40 further has a base magnetic attraction region 46, which is located on the opposite side of the base unit 40 from the second support unit 30, and a plurality of magnets 47 are embedded within the base magnetic attraction region 46. As a result, the base unit 40 can be attracted to a vertical metal surface. By providing a shielding material inside the base unit 40, the magnetic force is mainly concentrated on the base magnetic attraction region 46 side, and the magnetic force on the back side is significantly reduced. This suppresses the influence of magnetic force on the operation of the rear structure.

[0038] As a result, this invention can be installed on a horizontal surface, held between objects, or attached to a metal wall or machine surface, significantly improving the versatility of its usage scenarios and expanding the range of product applications. Furthermore, a soft pad 48 may be provided on the surface of the base magnetic attraction area 46, and the soft pad 48 can prevent scratches on the surface of the object without affecting the magnetic attraction force of the magnet 47.

[0039] The following describes several uses of the present invention.

[0040] As shown in Figure 6, the movable clamping member 43 and the fixed clamping member 42 clamp the flat object, and by adjusting the relative angles of the second support unit 30, the first support unit 20, and the mounting unit 10, the mobile device 70 is attracted to the magnetic attraction area 12 of the mounting unit 10. In this way, the user can view the video played on the mobile device 70.

[0041] As shown in Figure 7, the base magnetic attraction region 46 provided on the back surface of the base unit 40 allows it to be attracted to a metal wall surface, and by adjusting the relative positions of the second support unit 30, the first support unit 20, and the mounting unit 10, a different usage configuration can be formed.

[0042] As shown in Figures 8 and 9, the base unit 40 may be placed directly on a desk or a flat platform, and by adjusting the relative positions of the second support unit 30, the first support unit 20, and the mounting unit 10, the user can conveniently view the images displayed on the mobile device 70 on the desk. The above is only one of the uses of the present invention and does not limit the scope of application of the present invention.

[0043] As shown in Figures 10 and 11, Embodiment 2 of the present invention is shown. In this embodiment as well, the portable mobile device stand of the present invention includes the mounting unit 10, the first support unit 20, the second support unit 30, and the base unit 40, and its connection structure is the same as in the embodiment described above.

[0044] However, the mounting unit 10 is configured to clamp and secure the mobile device. In this embodiment, the mounting unit 10 includes a first clamping piece 14 and a movable second clamping piece 15, and a spring is provided inside the mounting unit 10 to bias the second clamping piece 15, thereby maintaining the fastening strength in the clamped state. When not in use, the first clamping piece 14 and the second clamping piece 15 can be positioned overlapping on the upper surface of the mounting unit 10 to reduce the volume when stored. As can be seen from the above, the fixing method of the mounting unit 10 can be designed as magnetic attraction, clamping, or other structures capable of securing the mobile device, depending on the needs.

[0045] As described above, the portable mobile device stand according to this invention employs a support structure that can rotate in multiple axes, a foldable three-layer laminated structure, and a base configuration that supports various fixing methods, thereby simultaneously achieving high portability, multi-angle adjustment capability, and stable fixing effect without complicating the structure. This reliably solves the problems related to portability and flexibility of use that were lacking in conventional mobile device stands, and possesses remarkable technological advancement and practical value.

Equivalent changes and modifications made based on the claims of the utility model registration of the present invention are all included within the scope of the claims of the present invention.
