[0001] The present invention relates to the technical field of tablet computer supporting equipment, and in particular to a tablet computer support frame. Background Art

[0002] The supporting parts of the keyboard leather cover of the existing tablet computer are connected by the leather cover. Since the leather cover is soft, the keyboard leather cover has a poor supporting effect on the tablet computer. If the tablet part has a slight external collision with the keyboard part, it is easy to cause the tablet to fall over.

[0003] Moreover, when using it, the user needs to align the lower part of the tablet with the groove on the keyboard support, which is not very convenient to use. Summary of the invention

[0004] In view of the problems existing in the prior art, the main purpose of the present invention is to provide a tablet computer support stand, which has a better supporting effect and provides convenience for users to use the tablet computer and input keyboard.

[0005] To achieve the above-mentioned purpose, the tablet computer support frame proposed by the present invention is used to support the tablet computer and its matching input keyboard, and comprises:

[0006] A base, one side of which is bent upward to form a first bent portion;

[0007] A sliding plate for carrying the input keyboard, the sliding plate is slidably matched with the base, and a side of the sliding plate close to the first bending portion is bent upward to form a second bending portion;

[0008] A support plate for carrying a tablet computer, the lower end of which is pivotally connected to the second bending portion of the sliding plate;

[0009] And a connecting plate, one end of which is pivotally connected to the first bending portion of the base, and the other end of which is pivotally connected to the supporting plate.

[0010] When the support plate rotates in a first direction relative to the sliding plate, the lower end of the support plate rotates in a second direction with the pivot point between the connecting plate and the support plate as the rotation center, thereby driving the sliding plate to be folded into the base or extended from the base.

[0011] The first direction is opposite to the second direction.

[0012] Optionally, the lower surface of the sliding plate has a receiving groove, and a slide rail is arranged in the receiving groove.

[0013] The slide rail comprises a fixed plate and a movable plate which are slidably matched, the fixed plate is fixed on the base, and the movable plate is engaged in the accommodating groove.

[0014] Optionally, both sides of the movable plate are bent upward and then bent toward the center of the movable plate for a second time to form two oppositely arranged slots, and POM rubber strips are respectively arranged in the two slots, and the POM rubber strips have sliding grooves.

[0015] The fixed plate is bent upward and then bent outward for a second time relative to the center of the movable plate to form two plug-in parts arranged back to back, and the two plug-in parts are respectively plugged into the sliding grooves of the POM rubber strip.

[0016] Optionally, the fixing plate has a plurality of first screw holes, the base has second screw holes corresponding to the first screw holes one by one, and the fixing plate is fixed to the base by screws that penetrate the first screw holes and are inserted into the second screw holes.

[0017] Optionally, the base has two first positioning columns, and the fixing plate has first positioning holes corresponding to the first positioning columns.

[0018] Optionally, a portion of the movable plate corresponding to the first screw hole has an avoidance area, and a portion of the sliding plate corresponding to the avoidance area has an avoidance hole, so that the first screw hole is exposed outside the sliding plate.

[0019] Optionally, the movable plate has a plurality of third screw holes, the receiving groove has fourth screw holes corresponding to the third screw holes one by one, and the movable plate is fixed in the receiving groove by screws penetrating the third screw holes and inserted in the fourth screw holes.

[0020] Optionally, two second positioning posts are provided in the accommodating groove, and the movable plate has second positioning holes corresponding to the second positioning posts.

[0021] Optionally, the first bending portion of the base has a first convex portion, the lower end of the connecting plate has a first groove corresponding to the first convex portion, the first convex portion is inserted into the first groove, and is pivotally connected to the lower end of the connecting plate through an axis.

[0022] The second bending portion of the sliding plate has a second groove, the lower end of the support plate has a second convex portion corresponding to the second groove, the second convex portion is inserted into the second groove, and is pivotally connected to the second bending portion of the sliding plate through a shaft.

[0023] Optionally, the base, sliding plate, supporting plate and connecting plate are all made of steel plates.

[0024] The present invention arranges the sliding plate slidably on the base, pivots the support plate to the sliding plate, and uses the connecting plate to realize the pivot connection between the support plate and the base. Therefore, when the support plate is rotated in a first direction relative to the sliding plate by an external force, the supporting plate can be pulled by the connecting plate, so that the lower end of the supporting plate rotates in a second direction relative to the connecting plate, and the sliding plate is driven to be retracted into the base or extended from the base.

[0025] In this way, the sliding plate can be pushed outward while the support plate is unfolded, providing convenience for the user to place the tablet computer and input keyboard.

[0026] Moreover, the sliding plate, the supporting plate and the connecting plate are bolted in pairs, wherein the connecting plate is indirectly bolted to the sliding plate through the base, which can provide good support for the supporting plate and enhance the supporting stability of the supporting plate.

[0027] Moreover, when the support plate is closed, the sliding plate can be synchronously driven to fold into the bottom 1, so as to provide convenience for users to carry.

[0028] Moreover, the bottom plate, the sliding plate, the supporting plate and the connecting plate can be stacked together to form a sandwich-like shape in a closed state, and are small in size and easy to store and carry.

[0029] In addition, the present invention can also be applied to tablet computers and input keyboards of various sizes, and has strong versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to provide a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please refer to the instruction manual Figure 1 In an embodiment of the present invention, a tablet computer support frame is proposed, which is used to support a tablet computer and a matching input keyboard. Specifically, the tablet computer support frame includes a base 1, a sliding plate 2, a support plate 3 and a connecting plate 4. The right side of the base 1 is bent upward to form a first bending portion 1a. The sliding plate 2 is slidably matched with the base 1, and its right side is bent upward to form a second bending portion 2a. The lower end of the support plate 3 is pivotally connected to the second bending portion 2a of the sliding plate 2. The lower end of the connecting plate 4 is pivotally connected to the first bending portion 1a of the base 1, and the upper end thereof is pivotally connected to the support plate 3.

[0039] like Figure 2-3 As shown, when the support plate 3 rotates to the right relative to the sliding plate 2, before the support plate 3 rotates to 90 degrees, the connecting plate 4 will rotate to the right along with the support plate 3 and pull the support plate 3, so that the lower end of the support plate 3 rotates to the left relative to the connecting plate 4, pushing the sliding plate 2 to move to the left and extend out of the base 1. After the support plate 3 rotates to 90 degrees, the connecting plate 4 will support the support plate 3 to rotate to the left, and the lower end of the support plate 3 continues to move to the left to push the sliding plate 2 to further extend out of the base 1, and drive the connecting plate 4 to rotate to the left, so that the connecting plate 4 and the support plate 3 form a support structure with a certain angle.

[0040] In this way, when the support plate 3 is opened, the sliding plate 2 can be pushed outward to facilitate the user to place a tablet computer and input keyboard (not shown). In addition, the sliding plate 2, the support plate 3, and the connecting plate 4 are bolted in pairs (wherein the connecting plate 4 is bolted to the sliding plate 2 indirectly through the base 1), which can provide good support for the support plate and enhance the support stability of the support plate.

[0041] When the support plate 3 rotates relatively to the left side of the sliding plate 2, the sliding plate 2 can be synchronously driven to be folded into the base 1, thereby facilitating the storage and carrying of the entire support frame.

[0042] In this embodiment, the height of the first bent portion 1a is greater than the height of the second bent portion 2a. In this way, when the sliding plate 2 is folded into the base 1, it can be completely sandwiched between the base 1 of the support plate 3, and the connecting plate 4 can cover the upper surface of the support plate 3 in parallel, so that the support frame forms a sandwich-like stacked structure in the closed state, reducing the volume of the support frame, so that it is more convenient for users to store and carry.

[0043] In this embodiment, a notch 2f is provided at the right end of the sliding plate 2, thereby providing convenience for the user to turn the supporting plate 3.

[0044] Alternatively, if Figure 1 , 4 As shown in Figures 7 and 8, in this embodiment, the first bent portion 1a of the base 1 has a first protruding portion 1b, and the lower end of the connecting plate 4 has a first groove (not shown). During assembly, the first groove of the connecting plate 4 is sleeved on the first protruding portion 1b of the first bent portion 1a, and is pivotally connected to the first bent portion 1a through a shaft.

[0045] The second bending portion 2a of the sliding plate 2 has a second groove 2b, and the lower end of the support plate 3 has a second convex portion (not shown). During assembly, the support plate 3 is inserted into the second groove 2b of the second bending portion 2a and is pivotally connected to the second bending portion 2a of the sliding plate 2 via a shaft.

[0046] By providing the grooves and the convex parts, the pivoting structures between the base 1 and the connecting plate 4 and between the sliding plate 2 and the supporting plate 3 can be made more compact, which is helpful to simplify the overall structural design of the supporting frame. Moreover, the structure is simple and convenient for manufacturing and production.

[0047] Alternatively, if Figure 4-5 As shown, in this embodiment, the lower surface of the sliding plate 2 has a receiving groove 2c, and the receiving groove 2c is provided with a slide rail 5, and the slide rail 5 includes a fixed plate 52 and a movable plate 51 that are slidably matched. Figure 6-7 As shown, the fixed plate 52 is fixed on the base 1, and the movable plate 51 is engaged in the receiving groove 2c.

[0048] When the support plate 3 is opened to drive the sliding plate 2 to extend out of the base 1, the sliding plate 2 moves relatively to the left, and when the right side wall of the accommodating groove 2c abuts against the right end of the fixed plate 52, it can limit the support plate 3, so that the support plate 3, the base 1 and the connecting plate 4 maintain a stable triangular structure, providing good support for the support plate 3.

[0049] As a further example, Figure 5 As shown, in this embodiment, the two sides of the movable plate 51 are bent upward and then bent toward the center of the movable plate 51 for a second time to form two oppositely arranged slots 51a, and POM rubber strips 53 made of POM material are respectively provided in the two slots 51a, and the POM rubber strips 53 have a slide groove 53a.

[0050] The fixed plate 52 is bent upward and then bent outward for a second time relative to the center of the movable plate 51 to form two plug-in portions 52 a disposed opposite to each other. The two plug-in portions 52 a are respectively plugged into the slide grooves 53 a of the POM rubber strip 53 .

[0051] In this embodiment, the movable plate 51 and the fixed plate 52 of the slide rail 5 are both made of metal. The friction between metal and metal will produce sharp noise, and the wear resistance is poor, it is easy to get stuck, and the user experience is poor. To solve this problem, the present invention sets a POM rubber strip 53 between the fixed plate 52 and the movable plate 51 of the slide rail 5. The POM material has good wear resistance and can ensure that there will be no obvious sliding gap after sliding 100,000 times, and can avoid the friction sound between metal and metal. The sliding is smooth, which can provide users with a better sliding experience.

[0052] Alternatively, if Figure 5 and Figure 7 As shown, in this embodiment, the middle of the fixing plate 52 has two first screw holes 52b, and the base 1 has second screw holes 1c corresponding to the two first screw holes 52b. Thus, the fixing plate 52 can be fixed to the base 1 by screws that penetrate the first screw holes 52b and are inserted into the second screw holes 1c.

[0053] As a further feature, two first positioning columns 1d are provided on the base 1, and a first positioning hole 52c corresponding to the first positioning columns 1d is provided in the middle of the fixing plate 52. Thus, the fixing plate 52 can be positioned and pre-fixed by the first positioning columns 1d and the first positioning holes 52c, so as to be subsequently fixed by screws.

[0054] Furthermore, the movable plate 51 has an escape area 51d, and the portion of the sliding plate 2 corresponding to the escape area 51d has an escape hole 2d. In this way, when the escape area on the movable plate 51 moves to the middle of the fixed plate 52, the first screw hole 52b and the first positioning hole 52c can be exposed outside the sliding plate 2, so as to facilitate the positioning pre-fixation and screw locking of the fixed plate 52.

[0055] Alternatively, if Figure 5-6 As shown, in this embodiment, two third screw holes 51b are respectively provided at both ends of the movable plate 51, and the receiving groove 2c has fourth screw holes 2d corresponding to the four third screw holes 51b. The movable plate 51 is fixed in the receiving groove 2c by screws penetrating the third screw holes 51b and inserted in the fourth screw holes 2d. By locking the movable plate 51 in the receiving groove by screws, the slide rail 5 and the sliding plate 2 can be more closely matched.

[0056] As preferably, Figure 6 As shown, two second positioning columns 2e are provided in the receiving groove 2c, and second positioning holes 51c corresponding to the second positioning columns 2e are provided on the movable plate 51. Thus, the movable plate 51 can be positioned and pre-fixed by the second positioning columns 2e and the second positioning holes 51c, so as to be fixed by screws later.

[0057] Optionally, in this embodiment, the base 1, the sliding plate 2, the support plate 3 and the connecting plate 4 are all made of steel plates. By using steel plates as the main structural members of the support frame, the structure has high strength, good supporting effect, is not easy to deform, and has a strong texture, which can provide users with a better visual experience.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to be construed as limiting the present invention. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present invention should be included in the protection scope of the technical solution of the present invention.
