Description

BACKGROUND OF THE INVENTION 1. Technical field of the invention

[0001] The present invention relates generally to the technical field of a stand for a mobile device and in particular a portable stand for mobile devices. 2. Description of the state of the art

[0002] With the widespread use of mobile devices, users often need stands to hold their devices in the correct position and angle when watching videos, making video calls, or working with applications. Currently, there are various types of mobile device stands on the market, including table stands, clamp stands, and magnetic stands, each designed to meet different usage needs.

[0003] However, existing stands for mobile devices often have the following disadvantages: Firstly, most stands have a fixed design or only a single axis of rotation, which limits the adjustment angle of the mobile device and makes it difficult to adapt to different usage scenarios; secondly, some stands are large or thick, even when folded, making them inconvenient to transport; thirdly, the mounting method is usually limited to a single mode, such as simply being placed on a flat surface or only being able to be clamped to an object, thus lacking flexibility in use.

[0004] Although some existing stands feature multi-segment, rotating designs, these are often complex and cumbersome to use, or their stability after alignment is insufficient and they are prone to angular shifts due to external forces or vibrations, resulting in a poor user experience. Therefore, a pressing problem in this engineering field is how to provide a stand for mobile devices that is highly portable, offers multiple angle adjustments, and is suitable for various setup types, while maintaining both structural simplicity and stability. SUMMARY OF THE INVENTION

[0005] The present invention aims to provide a portable stand for mobile devices. A multi-axis swiveling design allows for easy adjustment of the height, tilt angle, and orientation of the mounted mobile device to achieve the optimal viewing or working position. Furthermore, the foldable, three-layer, and stackable design effectively reduces the volume after folding, facilitating storage and transport. Combined with a base unit offering multiple mounting options, the present invention also improves usability and stability for the user, enhancing the stand's overall user comfort.

[0006] To solve the aforementioned problem, the following technical solution is provided in the present invention:

[0007] The present invention provides a portable stand for mobile devices, comprising: a mounting unit, a first mounting unit, a second mounting unit, and a base unit. The mounting unit is used to secure a mobile device; the first mounting unit is pivotally connected to a first pivot joint of the mounting unit, so that the mounting unit is pivotable relative to the first mounting unit. The second mounting unit is pivotally connected to the first mounting unit, so that the first and second mounting units are pivotable along the same axis.The base unit is pivotably connected to the second mounting unit, so that the base unit can pivot relative to the second mounting unit, with the mounting unit, the first mounting unit and the second mounting unit and the base unit forming a three-layer construction when folded.

[0008] In a preferred embodiment, the fastening unit has a projecting first pivot joint to which the first mounting unit is pivotably connected, allowing the fastening unit to pivot relative to the first mounting unit. The base unit has a projecting second pivot joint to which the second mounting unit is pivotably connected, allowing the base unit to pivot towards or away from the second mounting unit. In the folded state, the first mounting unit and the second mounting unit are arranged or accommodated between the first and second pivot joints, thus forming the three-layer structure consisting of the fastening unit, the first mounting unit, the second mounting unit, and the base unit.

[0009] In a preferred embodiment, the base unit comprises a fixed clamping element, a movable clamping element, and an elastic element. The movable clamping element is movable relative to the fixed clamping element, and the elastic element is located within the base unit and acts upon the movable clamping element, thereby pressing the movable clamping element toward the fixed clamping element without an external force, thus providing a clamping force.

[0010] In a preferred embodiment, the movable clamping element is further provided with a pull ring, wherein the movable clamping element moves away from the stationary clamping element when the pull ring is pulled.

[0011] In a preferred embodiment, the pull ring is pivotably connected to the movable clamping element, with the pivot position being located on the side opposite the stationary clamping element.

[0012] In a preferred embodiment, the pull ring is a ring structure that can be opened and closed, comprising a first arc-shaped element and a second arc-shaped element pivotably connected to the first arc-shaped element. A spring is provided at the pivot point, and a closed ring structure is formed when the first arc-shaped element and the second arc-shaped element rotate to abut each other. Pressing the second arc-shaped element opens the ring so that it can be attached to a backpack or other ring-shaped component, thus improving portability.

[0013] In a preferred embodiment, the movable clamping element is provided on the side on which the pull ring is located with a projecting limit seat, wherein the shape of the limit seat corresponds to the shape of the pull ring and the pull ring can be temporarily fixed to facilitate storage and save space when the pull ring is pivoted so that it is arranged around the limit seat.

[0014] In a preferred embodiment, the base unit further comprises a magnetic base attraction area located on the side of the base unit facing away from the second mounting unit, with several magnets embedded in the magnetic base attraction area.

[0015] In a preferred embodiment, the fastening unit has a magnetic attraction area that contains at least one magnet which magnetically holds the mobile device to the holder.

[0016] In a preferred embodiment, the fastening unit holds the mobile device in a clamping mode.

[0017] Compared to the prior art, the portable stand for mobile devices of the present invention achieves high portability, multiple angle adjustability, and stable mounting without increasing structural complexity through a multi-axis, pivoting support, a foldable, three-layer, stackable design, and a base unit configuration with multiple mounting options. The present invention effectively overcomes the shortcomings of existing stands for mobile devices with regard to portability and flexibility of use, representing a significant technological advancement and practical value.

[0019] The technical solutions of the present invention are described clearly and completely below in conjunction with the specific embodiments and the accompanying drawings. It should be noted that when an element is described as being "attached" or "fixed" to another element, this means that the element may be directly attached to the other element or that an intermediate element may be present. When an element is described as being "connected" to another element, this means that the element may be directly connected to the other element or that intermediate elements may be formed. In the illustrated embodiment, the directions up, down, left, right, front, and back, etc., are relative and are used to illustrate that the configurations and movements of the various components are relative in this case.These specifications are accurate if the components are in the positions shown in the figures. However, if the description of the element positions changes, it is assumed that these specifications will change accordingly.

[0020] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as they are generally understood by a person skilled in the art in the field of the present invention. The terminology used here serves only to describe certain embodiments and is not intended to limit the present invention. As used herein, the term "and / or" includes any and all combinations of one or more of the related elements listed.

[0021] Fig. 1 and Fig. Figure 2 shows perspective views of the first embodiment of the present invention in the folded and unfolded states. The present invention is a stand or mount for a portable mobile device and is primarily intended to solve the following problems, such as the difficulties in folding and storing, inconveniences in carrying, and limitations in angle adjustment and mounting methods of existing stands for mobile devices. The portable stand for a mobile device of the present invention comprises a mounting unit 10, a first mounting unit 20, a second mounting unit 30, and a base unit 40. The mounting unit 10 is used to attach, i.e., hold, a mobile device.The first mounting unit 20 is rotatably and pivotably connected to the mounting unit 10. The second mounting unit 30 is rotatably connected to the first mounting unit 20, allowing both the first and second mounting units 30 to rotate around the same axis. The second mounting unit 30 is rotatably and pivotally connected to the base unit 40. This multi-axis rotation allows the mobile device to be positioned in multiple directions and angles, significantly improving the stand's adaptability for mobile devices in various usage scenarios.

[0022] In particular, the fastening unit 10 is connected to a projecting first pivot joint 11, and the first mounting unit 20 is pivotally connected to the first pivot joint 11, so that the fastening unit 10 can rotate relative to the first mounting unit 20. The second mounting unit 30 is rotatably connected to the first mounting unit 20 along the same axis, so that the first mounting unit 20 and the second mounting unit 30 can be rotated along the same axis for connection. The base unit 40 is provided with a projecting second pivot joint 41, wherein the second mounting unit 30 is pivotally connected to the second pivot joint 41, so that the base unit 40 can rotate towards or away from the second mounting unit 30.

[0023] When folded, the first mounting unit 20 and the second mounting unit 30 are positioned between the first swivel joint 11 and the second swivel joint 41, forming a three-layer structure with the mounting unit 10, the first mounting unit 20, the second mounting unit 30, and the base unit 40. This effectively reduces the overall height and volume after folding, improving portability and storage efficiency, making the stand particularly suitable for outdoor activities or mobile use.

[0024] The base unit 40 exhibits, as in Fig. Figure 4 shows a fixed clamping element 42, a movable clamping element 43, and at least one elastic element 44 at the end furthest from the second pivot joint 41. The elastic element 44 is located inside the base unit 40 and provides the force that automatically moves the movable clamping element 43 towards the fixed clamping element 42. A pull ring 45 is also provided on the movable clamping element 43. Pulling the pull ring 45 simultaneously moves the movable clamping element 43, thus providing an additional clamping and fastening method for the base unit 40.

[0025] For use, the mobile device is attached to the mounting unit 10, placed directly on a flat surface using the base unit 40, or secured to various fixed objects using the fixed clamping element 42 and the movable clamping element 43. Users can adjust the height, tilt angle, and direction of the mobile device according to their needs by adjusting the relative rotation between the first mounting unit 20, the second mounting unit 30, and the base unit 40 to achieve the optimal viewing or working position, thus improving user comfort and practicality.

[0026] The mounting unit 10 uses a magnetic attraction mode to secure the mobile device and features a magnetic attraction area 12 with at least one magnet 13 embedded within the magnetic attraction area 12, enabling the mobile device to be quickly and securely attached to the mounting unit 10. This magnetic mounting mode significantly reduces the mounting and dismounting time of the mobile device, while also avoiding the problems of scratches on the device body or size compatibility limitations present in conventional designs.Furthermore, the fastening unit 10 contains a barrier material so that the magnetic force is mainly concentrated on the side where the magnetic attraction area 12 is located, while the magnetic force on the back part is significantly reduced, thus preventing the magnetic force from affecting the rotation of the rear components, thereby improving the smoothness and stability of adjusting the rotation.

[0027] As in Fig. As shown in Figure 3, the connection mechanism between the first mounting unit 20 and the second mounting unit 30 is provided with a positioning and coupling design. This design comprises several positioning projections 21 evenly distributed at angles on the connection surface of the first mounting unit 20, and several positioning grooves 31 on the connection surface of the second mounting unit 30. When the first mounting unit 20 and the second mounting unit 30 are rotated at a specific angle, the positioning projections 21 are positioned within the positioning grooves 31, thereby achieving a temporary position and preventing angular displacement of the mobile device due to vibration or external force during use, thus improving support stability.

[0028] The design further comprises a convex shaft 22 located in the first mounting unit 20, a shaft hole 32 located in the second mounting unit 30, a spring 33, and a bolt 34. When the convex shaft 22 is inserted into the shaft hole 32, the spring 33, from the other side of the second mounting unit 30, enters the sleeve on the outside of the convex shaft 22 to be locked with the bolt 34, so that the first mounting unit 20 and the second mounting unit 30 can rotate along the same axis and have the ability of a small axial displacement, thus creating a balance between frictionless rotation and overall structural strength.

[0029] The second mounting unit 30 is pivotally connected to the base unit 40, and its pivot position is outside the connection area of ​​the second mounting unit 30 and the first mounting unit 20. The base unit 40 rises with a second pivot joint 41, and the second mounting unit 30 is pivotally connected to the second pivot joint 41. The fixed clamping element 42 and the second pivot joint 41 rise together from the same side face of the base unit 40 and are arranged at opposite ends.In the folded state, the fastening unit 10, the first mounting unit 20 and the second mounting unit 30 can be accommodated between the fixed clamping element 42 and the second swivel joint 41, thus forming a three-layer construction with the fastening unit 10, the first mounting unit 20, the second mounting unit 30 and the base unit 40, thereby reducing the overall height after folding.

[0030] As in Fig. As shown in Figure 4, the base unit 40 comprises the fixed clamping element 42, the movable clamping element 43, and at least one elastic element 44 at the end furthest from the second pivot joint 41. The fixed clamping element 42 is erect on the surface of the base unit 40, and the movable clamping element 43 is L-shaped, with one section projecting into the interior of the base unit 40 and capable of linear movement away from the fixed clamping element 42. The elastic element 44, e.g., a spring, is located inside the base unit 40 and rests against the movable clamping element 43. When no external force is applied, the elastic element 44 pulls the movable clamping element 43 toward the fixed clamping element 42 to maintain the positive locking connection. The internal structural form of the main body of the movable clamping element 43 is an L-shaped sheet 431.The L-shaped design 431 only improves the structural rigidity, but also increases the weight of the base unit 40, making it more stable when placed on a work surface.

[0031] In the present embodiment, the pull ring 45 is pivotally connected to the movable clamping element 43, and the pivot position is on the side of the movable clamping element 43 facing away from the stationary clamping element 42. When the user pulls on the pull ring 45, the movable clamping element 43 moves away from the stationary clamping element 42, thus facilitating the clamping of both the stationary clamping element 42 and the movable clamping element 43 to the object to which they are to be attached. After the external force is released, the movable clamping element 43 moves closer to the stationary clamping element 42 using the restoring force of the elastic element 44, thereby maintaining the normal clamping force.

[0032] According to a second embodiment, the pull ring 45 is an open and closed design comprising: a first arc-shaped element 451 and a second arc-shaped element 452 pivotally connected to the first arc-shaped element 451, with a spring located at the pivot point. When the first arc-shaped element 451 and the second arc-shaped element 452 are pivoted so that they abut each other, the ring forms a closed configuration. The ring is opened by pressing the second arc-shaped element 452, allowing it to be attached to an annular component of a backpack or other device, thus improving portability.

[0033] The movable clamping element 43 rises with a limit seat 432 on the side where the pull ring 45 is located, the shape of which corresponds to the shape of the pull ring 45. When the pull ring 45 is pivoted so that it is positioned around the limit seat 432, its position is temporarily fixed to allow for easy and space-saving storage. When a greater external force is applied to push the pull ring 45, it rises from the surface of the movable clamping element 43. Furthermore, a threaded bore 433 is provided in the center of the limit seat 432. The threaded bore 433 is used to fasten the locking bolt in the central part of the camera tripod platform, thus providing an additional usable configuration.

[0034] As in Fig. As shown in Figure 5, the base unit 40 also has a magnetic base attraction area 46 located on the side of the base unit 40 facing away from the second mounting unit 30. Several magnets 47 are embedded in the magnetic base attraction area 46, enabling the base unit 40 to be attracted to a vertical metal surface. The base unit 40 also has a barrier material (e.g., a yoke) inside, so that the magnetic force is concentrated mainly on the side of the magnetic base attraction area 46, while the magnetic force on the opposite side is significantly reduced, thus preventing the magnetic force from interfering with the use of the components behind it.Therefore, the present invention can be placed on a horizontal surface or clamped to an object, as well as attracted to a metal wall or the surface of a device, which significantly increases the variety of application scenarios and expands the product's application range. Furthermore, a soft pad 48 can be provided on the surface of the magnetic base attraction area 46, which does not impair the magnetic attraction of the magnets 47 and also prevents scratching of objects.

[0035] The following are some application scenarios of the present invention:

[0036] As in Fig. As shown in Figure 6, the movable clamping element 43 and the fixed clamping element 42 are used to attach a flat object. By adjusting the relative angles of the second mounting unit 30, the first mounting unit 20, and the fastening unit 10, the mobile device 70 is magnetically attached to the magnetic attraction area 12 of the fastening unit 10, allowing the user to view the images displayed by the mobile device 70.

[0037] As in Fig. As shown in Figure 7, the magnetic base attraction area 46 on the back of the base unit 40 is used for attachment to a metal wall. A different mode of use is achieved by adjusting the relative positions of the second mounting unit 30, the first mounting unit 20, and the fastening unit 10.

[0038] As in Fig. 8 and Fig. As shown in Figure 9, the base unit 40 can also be placed directly on a desk or flat platform. By adjusting the relative positions of the second mounting unit 30, the first mounting unit 20, and the fastening unit 10, the user can conveniently view the images displayed by the mobile device 70 on a desktop. The above description merely illustrates some uses of the present invention and is not intended to limit its scope.

[0039] Fig. 10 and Fig.Figure 11 shows a second embodiment of the present invention. According to this second embodiment, the stand for the mobile device comprises the following: the mounting unit 10, the first mounting unit 20, the second mounting unit 30, and the base unit 40. The design is the same as in the aforementioned embodiment, except that the mounting unit 10 holds the mobile device in a clamping position. In this embodiment, the mounting unit 10 has a first clamping element 14 and a movable second clamping element 15 and also includes a spring that moves the second clamping element 15 to maintain a secure, positive fit. When not in use, the first fixed clamping element 14 and the second fixed clamping element 15 can be attached to the top of the mounting unit 10 to reduce the overall storage volume.Therefore, the fastening unit 10 can be designed as a magnetic, clamping or other type of construction for fastening the mobile device, depending on requirements.

[0040] In summary, the portable stand for mobile devices according to the present invention achieves high portability, the ability to adjust to multiple angles, and a stable mounting effect without increasing structural complexity through the use of a multi-axis pivoting design, a foldable three-layer design, and a base unit configuration with multiple mounting devices. The present invention effectively overcomes the shortcomings of existing stands for mobile devices with regard to portability and flexibility of use, and represents a significant technological advancement and practical value.

[0041] Although the present invention has been described with reference to its preferred embodiments, it is apparent to the person skilled in the art that a multitude of modifications and changes can be made without departing from the scope of the present invention, which is to be expressed by the appended claims.

[0042] In summary, the present invention provides a portable stand for a mobile device 70, comprising: a mounting unit 10, a first mounting unit 20, a second mounting unit 30, and a base unit 40. The mounting unit 10 is used to attach a mobile device 70. The first mounting unit 20 is pivotally connected to a first pivot joint 11 of the mounting unit 10, allowing the mounting unit 10 to rotate relative to the first mounting unit 20. The second mounting unit 30 is rotatably connected to the first mounting unit 20, allowing the first and second mounting units 20, 30 to rotate along the same axis.The base unit 40 is pivotally connected to the second mounting unit 30, so that the base unit 40 can rotate relative to the second mounting unit 30, whereby in a folded state the mounting unit 10, the first mounting unit 20, the second mounting unit 30 and the base unit 40 form a three-layer construction shape, thereby achieving high portability, multi-angle adjustability and stable multiple fixing modes for various usage scenarios.
