The abutting arc surface 53 is used for pressing the abutting block 51 to compress the elastic piece 52 to generate nonlinear damping, namely friction damping, when the sliding block 44 slides along the abutting arc surface 53 in the sliding groove 42, so as to balance weight damping generated by gravity in the rotation process of the tablet computer. In this embodiment, the weight damping generated by the gravity of the loading frame and the tablet computer may determine a range value, determine a range of the non-linear damping generated by the sliding of the slider 44 in the abutting arc surface 53 and pressing the elastic member 52 according to the range value, and determine the radian of the abutting arc surface 53 according to the range of the non-linear damping. The length of the abutment arcs 53 are dimensioned to ensure the sliding distance of the slide 44 required for the carriage 20 from the closed position to the fully open position.

In one embodiment, the elastic member 52 is a plurality of coil springs, the plurality of coil springs are arranged at intervals, one end of each coil spring is connected to the connecting surface 54 of the abutting block 51, and the other end of each coil spring is used for being fixedly connected to the base 10. The plurality of helical springs are arranged at equal intervals, so that the moving stability of the abutting block 51 in the process of being abutted by external force can be ensured. In other embodiments, the elastic member 52 may be a rubber strip having elasticity; or a damper, which can assist the non-linear damping generated when the holding block 51 is pressed by the slider.

Referring to fig. 5 and 7, the positioning portion 50 is installed in the accommodating cavity 15, the other end of the elastic element 52 away from the abutting block 51 is fixedly connected to the cavity wall 151, one end of the abutting block 51 having the abutting arc 53 is exposed through the opening 152, a portion of the abutting block 51 connected to the first edge 531 protrudes out of the sliding slot 44, and the abutting arc 53 faces the sliding slot, wherein the portion of the abutting block 51 connected to the first edge 531 may be an end of the abutting block 51 or a region with a certain length in the length direction of the abutting block 51. The first edge 531 of the abutting arc surface 53 is located at the initial position and protrudes out of the surface of the slot sidewall 421, and the second edge 532 is connected to the slot sidewall on one side of the opening 152 and can also be located in the opening, which can be understood as that along the first direction X, the distance between the abutting arc surface 53 and the slot sidewall 421 opposite to the abutting arc surface is gradually increased, that is, the distance between the two opposite sides of the slider 44 and the abutting arc surface 53 and the slot sidewall 421 is gradually generated, and the abutting force of the slider 44 on the abutting block 51 is reduced in the sliding stroke of the slider 44.

In one embodiment, a guide groove (not shown) is disposed in the accommodating cavity 15, and the elastic member 52 is disposed in the guide groove of the accommodating cavity 15 and can extend and contract along the guide groove, so as to ensure the elasticity directionality of the elastic member 52 and the stability of the sliding direction of the abutting block 51. In other embodiments, a guide post is disposed on the connecting surface 54 of the abutting block 51, one end of the coil spring is fixed on the cavity wall 151, and the other end of the coil spring is sleeved on the guide post, and the coil spring stretches along the guide post when the abutting block 51 slides in the accommodating cavity 15, so as to ensure stability of the sliding direction of the abutting block 51.

With reference to fig. 7, when the loading frame 20 is in the closed state, the bracket 30 is accommodated in the second region of the sliding groove 42, the sliding block 44 is located in the first region of the sliding groove 42 and abuts against between the abutting arc surface 53 and one of the groove side walls 421, and the head end 441 of the sliding block 44, specifically, the side portion of the head end 411 abuts against the portion of the abutting arc surface 53 having the first edge, so that the loading frame can be positioned relative to the closed state of the base, the elastic member 52 is in the pre-compression state in the second direction, and the first direction is perpendicular to the second direction. In other embodiments, the head end 441 of the slider 44 abuts against the abutting arc surface 53, the plurality of elastic members 52 are in a free state, and a force for abutting against the abutting block 51 is generated during sliding, so that the bearing frame 20 is locked with the base 10 through the locking structure.

As shown in fig. 8 and 9, fig. 8 is a side plan view of the carriage of the support device of fig. 3, shown slid at an angle, wherein the internal structural contours can be seen; fig. 9 is a sectional view of a part of the supporting device shown in fig. 8 in a supporting state. When the carrying frame 20 needs to be opened, a human hand pushes the carrying frame 20 to the first direction X to drive the sliding block 44 to slide from the initial position to the first direction X, the carrying frame 20 rotates relative to the sliding block 44 while the sliding block 44 slides, namely, rotates relative to the base 10, so that the position of the top frame 21 is opened relative to the surface 11 of the base 10 first and then pushes the support 30 to the first direction X, and the support 30 rotates relative to the carrying frame 20 and one end connected with the base 10 rotates out of the sliding groove 42; i.e. the carrier 20 and the stand 30 open in an inverted V-shape relative to the base 10. At the same time, the slider 44 slides along the abutting arc surface 53 and pushes the abutting block 51 to compress the elastic member 52 in the second direction (the direction perpendicular to the first direction). Along with the sliding and rotation of the bearing frame 20, the supporting angle of the bearing frame 20 is adjusted, after the supporting angle of the bearing frame 20 is determined, after the external force pushing the bearing frame 20 is removed, the resilience force of the elastic member 52 pushes against the abutting block 51, and further pushes against the sliding block 44 to enable the sliding block 44 to be in interference fit with the sliding groove 42, at this time, the sliding block 44 is positioned at a certain position and does not slide any more, the distance from the head end 441 of the sliding block 44 to the joint of the bracket 30 and the sliding groove 42 is fixed, and the bearing frame 20, the bracket 30 and the space between the bracket 30 and the head end 441 of the sliding block 44 form a triangular support, so that the supporting angle of the bearing frame 20 is adjusted and positioned, a user can watch and operate the tablet computer on the bearing frame 20, and after the bearing frame 20 is angularly supported, the keyboard 60 on the base 10 can also be exposed, so that the tablet computer can be operated through the keyboard, and the operation of the bearing frame is more convenient.

In the process of opening the bearing frame 20, since the slider 44 abuts against the abutting block 51 of the side wall 421 of the protruding groove when in the initial position, the slider 44 slides along the abutting arc surface 53 in the first direction X, the abutting block 51 is pushed into the accommodating cavity 15 and the elastic member 52 is compressed when sliding, and as the curvature of the abutting arc surface 53 becomes larger, the abutting force on the abutting block 51 during the sliding process of the slider 44 decreases gradually, and the elastic member 52 is compressed all the time and generates a reverse resilience force to push the abutting block 51 to abut against the slider 44 to generate friction damping; when the supporting angle of the loading frame 20 is close to 90 degrees, the interaction force between the sliding block 44 and the abutting arc surface 53 is minimum. The weight damping force is generated by the gravity of the bearing frame and the tablet computer in the rotating process, the difference between the weight damping force and the friction damping force is constant, and the damping change can not be sensed due to the constant damping force in the process of pushing the bearing frame by the external force of hands. In this embodiment, frictional damping is greater than the weight damping, guarantees that people's hand pushes the in-process and feels and obtains stable damping, can not produce the damping because of the unstability of hand thrust and feel. For example, the friction damping is explained, when the slider 44 slides in the sliding slot 42 along the first direction X, the abutting block 51 is pushed to extrude the elastic member 52, because the abutting block 51 protrudes out of the sliding slot just before the slider 44 slides, the resistance when the slider 44 starts sliding is the largest, for example, the displacement when starting sliding is the first section displacement, the damping generated by compressing the elastic member 52 in the first section displacement is 5N, the damping generated by compressing in the second section displacement is 3N, the damping generated by compressing in the third section is 1N, the compression amount of the three sections of displacement on the elastic member 52 is different, the elastic counterthrust generates different damping, so that the slider 44 and the abutting block 51 are in nonlinear contact, and the friction damping is generated. In other embodiments, the positioning portion 50 may be a damper, and the slider 44 cooperates with the damper during sliding, so that the non-linear damping is realized by the damper to balance with the damping generated by the sum of the weight of the tablet computer and the weight of the loading frame.

The supporting device 100 of the application is used for supporting the tablet computer, the loading frame 20 is opened and closed relative to the base 10 in a sliding mode, the loading frame 20 can be opened relative to the base 10 by pushing the side part of the loading frame 20 with a single hand or other external force, and the user experience is improved. And the friction damping and the weight damping generated in the sliding process of the bearing frame 20 are balanced, so that the damping is constant when the bearing frame is pushed by a hand, the bearing frame can be opened easily, the operation is convenient, and the use comfort level is improved. Further, the supporting angle of the loading frame 20 is adjusted already during the sliding process of the loading frame 20, and as long as the driving external force is removed, the positioning portion 50 located on the sliding track limits the distance between the loading frame 20 and the bracket 30 to angularly position the loading frame 20 and ensure the supporting stability, so that the overall supporting device 100 is more convenient to operate and achieves the purpose of multi-angle supporting.

In another embodiment, a motor is disposed between the end of the slider 44 and the first end 422 of the sliding slot 42, and an actuating button of the motor is configured on the base 10, and is pressed to be powered on, and is released to be powered off.
