Description

Flat scaffolding structure

This invention relates to a flat stand structure, particularly a stand that is assembled on the back of a flat electronic device and can be opened or closed relative to the flat electronic device.

Currently, most common flat electronic devices such as tablet computers or AIO computers are supported by a support stand to allow the flat electronic device to stand. The support stand is further hinged with a pivot structure to perform a flipping action, so that the support stand can be opened or closed relative to the flat electronic device, and the standing angle of the tablet computer has a stepless or multi-stage adjustment and positioning function, so that the tablet computer can be stably positioned when lying flat or at different standing angles, so as to facilitate user touch operation.

The traditional hinge structure is installed between the flat electronic device and the supporting stand. It mainly generates rotational torque to resist the force and weight during operation. In order to generate sufficient rotational torque, each component in the pivot structure of the supporting stand must have sufficient thickness to maintain the minimum structural strength; or in order to make the flipping operation smooth, the structure of the component is complicated, which is not only not conducive to assembly, but also increases the overall size. However, in order to facilitate users to carry and operate, the thinning of flat electronic devices is one of the goals actively pursued by the industry.

Therefore, as shown in the patent case of "Tripod Structure" in announcement No. CN215215626U, a pair of guide rails are provided in the hollow groove of a base body, and the pair of guide rails are respectively connected to the two ends of the first axis, and the first axis is pushed and pulled through the first elastic member and the second elastic member; the intermediate rotating member includes a first rotating plate and a second rotating plate, and the first rotating plate and the second rotating plate are respectively rotated in an arc relative to the first side plate and the second side plate of the base body; the first lug and the second lug of the rotating bracket are respectively relative to The first rotating plate and the second rotating plate rotate in an arc shape, and the second axis between the first lug and the second lug has a long plane section, a first outer diameter portion and a second outer diameter portion extending in sequence, and the diameter of the second outer diameter portion is larger than the diameter of the first outer diameter portion; one end of at least one connecting rod of the torque member is sleeved on the first axis, and the second friction torque portion at the other end of at least one connecting rod is sleeved on the second axis, so as to reduce the number of components and effectively utilize the space inside the structure, thereby having the advantages of sufficient strength, thinness and convenient assembly. However, the patent case No. CN215215626U is about sleeve-connecting the torque piece on the circumference of the shaft of the second axis of the rotating bracket to generate a variable curvature, thereby forming a variable torque during the opening process; however, in the actual production process, it is found that the circumferential shape of the shaft is difficult to control, and it is often impossible to generate accurate and effective phased rotational friction torque.

By changing the variable torque to the rear of the torque rod assembly, the first shaft column can slide in a pair of guide rails without rotating.

Thus, as shown in FIG. 1 and FIG. 4, in the initial stage of opening the flat stand, when the user directly or indirectly pulls the toggle plate 53 to open the rotating member 5, there are two situations due to the manufacturing tolerance of the parts. The first situation is that the rotating member 5 and the adapter 6 are turned over at the same time, as shown in FIG. 4, the outer convex track 72 of the frame connecting member 7 moves in the inner guide groove 65 of the adapter 6 in an arc shape, and the second The first limiting portion 31 and the second limiting portion 34 of a shaft 3 slide relative to each other in the first long groove 26 and the second long groove 27 respectively, so that the rotating member 5 and the adapter 6 can be opened relative to the frame member 2 at the same time and positioned at a certain angle; at this time, since the left arc block 722 and the right arc block 723 of the frame connecting member 7 respectively stop the adapter 6, the rotating member 5 and the adapter 6 will no longer rotate relative to the frame member 2. The difference in the second case is that only the rotating member 5 turns over, and the first inner guide portion 513 and the second inner guide portion 523 of the rotating member 5 respectively move in an arc shape in the first outer guide portion 631 and the second outer guide portion 641 of the adapter 6 until they are respectively stopped by the first stop portion 632 and the second stop portion 642 of the adapter 6, so that the rotating member 5 continues to drive the adapter 6 to enter the second stage of relative rotation.

As shown in FIG. 1 , FIG. 5 and FIG. 6 , in the second stage, when the user continues to pull the paddle 53 to continue to open the rotating member 5, in the first case, the first inner guide portion 513 and the second inner guide portion 523 of the rotating member 5 are connected by the first outer guide portion 631 and the second outer guide portion 641 of the adapter 6 in a relatively arc-shaped rotation manner; and in the second case, the outer convex track 72 of the frame connecting member 7 moves in an arc in the inner guide groove 65 of the adapter 6. In both cases, the first limit portion 31 and the second limit portion 641 of the first shaft 3 are moved. The limiting portion 34 slides relatively in the first long groove 26 and the second long groove 27, respectively, so that one end of the rotating member 5 and the other end of the torque rod assembly 4 rotate relatively to each other to generate a rotational friction torque. At the same time, when the rotating member 5 rotates to an opening angle of about 110 degrees, a gradual or two-stage torque change is generated through the interference between the first sleeve portion 43, the second sleeve portion 44 of the torque rod assembly 4 and the first torque portion 32, the second torque portion 35 of the first shaft 3, so as to stop the rotating member 5 from rotating to achieve the maximum opening angle.

FIG. 7 is a second embodiment of the flat scaffold structure 1 of the present invention, which is different from the first embodiment in that the pair of guide rails 25 of the frame member 2 includes a first linear slide rail 251 and a second linear slide rail 252, wherein the first side plate 21 has the first linear slide rail 251 on its inner side surface, and the first linear slide rail 251 includes a first upper rib 253 and a first lower rib 254 spaced apart from each other, so as to move the first side plate 21 to the first side plate 21.

FIG8 is a third embodiment of the flat plate support structure 1 of the present invention, which is different from the first embodiment in that: the first limiting portion 31 and the second limiting portion 34 are two through holes in the axial direction of the first shaft 3; the pair of guide rails 25 include two parallel straight rods (257, 257'), one end of the two straight rods (257, 257') respectively penetrates and locks the connecting plate 22, and after the two straight rods (257, 257') respectively penetrate the first limiting portion 31 and the second limiting portion 34, the other ends of the two straight rods (257, 257') are respectively connected to a fixing seat 258 of the frame member 2.

FIG. 9 is a fourth embodiment of the flat-plate support structure 1 of the present invention, which is different from the first to third embodiments in that: the first torque portion 32 has a first convex portion 321 on the outer periphery of the first shaft 3, and the second torque portion 35 has a second convex portion 351 on the outer periphery of the first shaft 3; and the first sleeve portion 43 of the first torque rod 41 of the torque rod assembly 4 includes an inverted C-shaped covering hole 433, and the inverted C-shaped covering hole 433 The first torque rod 41 has a first concave portion 434, and the open end of the inverted C-shaped covering hole 433 is perpendicular to the long direction of the first torque rod 41 to connect to a third slot 435; and the second sleeve portion 44 of the second torque rod 42 includes another inverted C-shaped covering hole 443, and the other inverted C-shaped covering hole 443 has a second concave portion 444, and the open end of the other inverted C-shaped covering hole 443 is perpendicular to the long direction of the second torque rod 42 to connect to a fourth slot 445. Thus, the first concave portion 434 and the second concave portion 444 push the first convex portion 321 and the second convex portion 351 respectively, and a step-by-step torque change can also be generated.

In summary, this invention changes the main variable torque to the rear of the torque rod assembly, and provides long sections at both ends of the first shaft, so that the first shaft can slide in a pair of guide rails without rotating. At the same time, by adjusting the interference amount of the torque rod assembly clamping the first shaft, a gradual or two-stage torque change in the rotation process can be achieved. Therefore, it is convenient to control the circumferential shape of the left shaft, right shaft and first shaft of the rotating part, thereby simplifying the process and improving the quality of the product. Furthermore, the frame of this invention is a metal plate stamping, which can not only facilitate the molding of various shapes of a pair of guide rails, but also effectively simplify the structure and shape of each part to save manufacturing costs, facilitate assembly and maintain structural strength, and at the same time reduce the overall thickness to meet the requirements of thinness.
