Detailed Description
Referring to fig. 1, a supporting device according to the present invention includes a base 1, a first bracket 21, a second bracket 22, a third bracket 23, and a fourth bracket 24. The base 1 is flat box-shaped and forms a chamber 11 inside. The two sides of the chamber 11 near the side wall of the base 1 are respectively provided with a plurality of tooth blocks 12 arranged along a longitudinal direction.
On the upper surface, the first support 21 and the second support 22 are respectively formed into a frame shape, wherein the bottom end of the first support 21 is pivotally disposed at one side of the base 1 and can pivot with respect to the base 1, and the second support 22 is pivotally disposed to intersect with the first support 21 by a pivot 20. As shown in fig. 2, the bottom of the second bracket 22 has a positioning end 221, the positioning end 221 extends downward to form a protrusion 222 capable of positioning against the tooth block 12, and extends laterally to form a stop column 223. An inner flange 13 is disposed on the sidewall of the base 1 near the tooth block 12, and the blocking pillar 223 extends below the inner flange 13. Accordingly, the second support 22 can be positioned by the protrusion 222 abutting against one of the teeth 12, when the position of the second support 22 must be changed with the change of the elevation angle of the first support 21, the second support 22 can be moved by lifting the second support 22 to make the protrusion 222 away from the teeth 12, and the blocking column 223 is blocked by the inner flange 13, so that the second support 22 can be prevented from completely separating from the base 1 and overturning the whole structure.
The third frame 23 is pivotally connected to the top end of the first frame 21 at the bottom end thereof, the fourth frame 24 is pivotally connected to the top end of the second frame 22 at the bottom end thereof, and the third frame 23 and the fourth frame 24 are pivotally connected to each other at the top ends thereof. The fourth bracket 24 is provided with a connecting portion (not shown) for connecting to the supported object, and the structure of the connecting portion is not limited in the present invention, and various technologies known in the art can be selected. The connecting portion is connected to a rotatable or fixed back plate for mounting a supported object, such as a mobile electronic device (not shown). In the present embodiment, a rotatable backplate 3 is selected, and when the backplate 3 is rotated as shown in fig. 4, the mobile electronic device can be turned to facilitate browsing by the user.
Accordingly, the first support 21, the second support 22, the third support 23, the fourth support 24 and the back plate 3 form a four-bar linkage structure, and can synchronously generate linkage action; in other words, as shown in fig. 3, when the backboard 3 and the fourth support 24 are lifted or lowered, the first support 21, the second support 22 and the third support 23 will synchronously pivot and swing, and automatically move to the position where the backboard 3 and the fourth support 24 can be stably supported.
Furthermore, the elevation angle and height of the mobile electronic device can be adjusted simultaneously by the action of the four-bar linkage structure formed by the supports. In detail, as shown in fig. 3, when the elevation angle of the mobile electronic device is raised, it will simultaneously drive the first support 21, the second support 22, the third support 23, and the fourth support 24 to swing and be raised; conversely, when the elevation angle of the mobile electronic device is lowered, the height is also lowered. Accordingly, the elevation angle and the height of the mobile electronic device can be adjusted together, thereby simplifying the adjustment mode and saving the adjustment time.
Moreover, when the elevation angle and height of the mobile electronic device are minimized, as shown in fig. 5, the first support, the second support, the third support and the fourth support are pivotally and flatly arranged and then accommodated in the accommodating chamber of the base 1, so that the overall structure is greatly reduced to be as flat as the base 1, thereby facilitating the accommodation and being convenient for carrying and use.
The present invention further provides a second embodiment as shown in fig. 6. The structure of this embodiment is different from the structure of the first embodiment in that the fourth support is omitted, and the object 4 is supported by the first support 21, the second support 22, and the third support 23. In detail, the second frame 22 is pivoted to the supported object 4 at the top end, and the third frame 23 is pivoted to the supported object 4 at the top end, so that when the supported object 4 is lifted up, the first frame 21, the second frame 22 and the third frame 23 are driven to swing to be raised; conversely, when the elevation angle of the supported object 4 is lowered, the height is also lowered. Accordingly, the elevation angle and the height of the supported object 4 can be adjusted together, thereby simplifying the adjustment method and saving the adjustment time.
Similarly, when the elevation angle and height of the supported object 4 are minimized, the first support 21, the second support 22 and the third support 23 are pivotally and flatly laid out and then contained in the base 1, so that the overall structure is greatly reduced to be as flat as the base 1, thereby facilitating storage and being convenient for carrying about.
The present invention further provides a third embodiment as shown in fig. 7, which comprises a base 5, a movable bottom frame 6, a first support 71, a second support 72, a third support 73 and a fourth support 74. The base 5 is hollow, and the movable bottom frame 6 can movably penetrate through the base 5. The first support 71 is pivotally disposed at a bottom end of the base 5, and can swing relative to the base 5. The second bracket 72 is pivoted to the first bracket 71 by a pivot 70, and the bottom end is pivoted to one side of the movable bottom frame 6. The third frame 73 is pivotally mounted at the top end of the first frame 71 at the bottom end thereof, the fourth frame 74 is pivotally mounted at the top end of the second frame 72 at the bottom end thereof, and the third frame 73 and the fourth frame 74 are pivotally mounted at the top ends thereof. The fourth bracket 74 is connected to a rotatable or fixed back plate 75, and the back plate 75 can be connected to a supported object, such as a mobile electronic device (not shown).
Accordingly, the first bracket 71, the second bracket 72, the third bracket 73, the fourth bracket 74 and the back plate 75 form a four-bar linkage structure, when the first bracket 71 swings up relative to the base 5, the second bracket 72 is pulled and lifted up, and then the third bracket 73, the fourth bracket 74 and the back plate 75 are pushed and lifted up, so that the elevation angle and the height of the supported object can be adjusted at the same time. In addition, as shown in fig. 8, in the process that the second bracket 72 is lifted along with the pivotal swing of the first bracket 71 relative to the base 5, the movable chassis 6 is pulled by the second bracket 72 and pushed out of the base 5, thereby enlarging the area contacting with the ground and more stably supporting the supported object.
The supported object can be fixed after the elevation angle and the height of the supported object are set. Specifically, as shown in fig. 7, 9 and 10, a plurality of rows of tooth blocks 61 are disposed along the movable chassis 6, and the base 5 is disposed with a movable positioning member 8, which includes a button 81 and a spring 82, wherein the button 81 is disposed with a convex pillar 811, the spring 82 is positioned on a fixed pillar 51 of the base 5, one end 821 is abutted against the convex pillar 811, and the other end 822 is abutted against the tooth blocks 61, and the convex pillar 811 is normally clamped on one of the tooth blocks 61 by its elastic force, so as to fix the first bracket 71 and the second bracket 72. When the first bracket 71 and the second bracket 72 are to be unlocked, the convex post 811 can be separated from the tooth block 61 by pressing the button 81, and the second bracket 72 can drive the movable chassis 6 to move relative to the base 5, thereby setting the angle and height of the supported object.
The above description is the preferred embodiment of the present invention and the technical principle applied by the same, and for those skilled in the art, without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention all belong to the protection scope of the present invention.
