Description

Technical Field

[0001] This utility model relates to the field of flat panel device technology, and in particular to a support frame for flat panel devices. Background Technology

[0002] Tablet devices are widely used in learning, working, and entertainment scenarios due to their portability and interactivity. As a supporting accessory, the angle adjustment capability, support stability, and structural compactness of tablet device stands directly affect the user experience.

[0003] Traditional tablet support stands are mainly divided into two categories. One type is a fixed-angle stand, which can only fix the tablet at a single preset angle and cannot flexibly adjust the viewing angle according to the usage scenario, resulting in poor adaptability. The other type is a stand that can adjust multiple fixed angles. Although it can provide a limited selection of angles, the angle switching relies on discrete structures such as buckles and gears, which cannot achieve continuous stepless adjustment and cannot meet the user's needs for precise viewing angle.

[0004] To achieve stepless adjustment within a certain angle range, some existing tablet support frames incorporate damping hinges (often used in laptop screen adjustment) to achieve stepless adjustment. However, damping hinges are typically large in size, complex in structure, and occupy a lot of space. Tablet support frames need to adapt to the thin and light characteristics of tablets, pursuing a lightweight and thin structural design. Existing damping hinges are difficult to accommodate this requirement—if they were used directly, it would result in an overall larger size and increased weight for the support frame, contradicting the core advantage of tablet portability.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation of the present invention and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present invention encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

[0022] It should be noted that, in order to clearly show the structural relationship of the internal key components of this utility model, some pipelines, lines, support brackets and other components of the actual product are omitted in the drawings. However, the specific design schemes of these omitted components are all easily implemented by those skilled in the art based on the technical solutions currently provided by this utility model and conventional design.

[0023] In the description of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0024] Example 1: like Figures 1-21 As shown, this utility model provides a flat panel device support frame for supporting flat panel device 1: The support frame 2 includes an upper support shell 21, a lower support shell 22, and a rotating mechanism 23. The rotating mechanism 23 includes a torque hinge 231 and a stop hinge 232. The torque hinge 231 includes an upper hinge 2311 and a lower hinge 2312. The bottom of the upper hinge 2311 is fixedly connected to the top of the lower hinge 2312. The upper hinge 2311 and the lower hinge 2312 can generate relative torsional deformation under force. When the rotating mechanism 23 is in the maximum rotation state, the torque hinge 231 is in the elastic deformation state. The stop hinge 232 includes an upper stop 2321 and a lower stop 2322 rotatably connected by a pivot 233. The bottom of the upper stop 2321 is provided with a first limiting structure 23211, and the top of the lower stop 2322 is provided with a second limiting structure 23221 that cooperates with the first limiting structure 23211 to limit the maximum rotation state of the rotating mechanism 23. The upper twist page 2311 and the upper stop page 2321 are connected to the upper support shell 21, and the lower twist page 2312 and the lower stop page 2322 are connected to the lower support shell 22. The upper support shell 21 is connected to the upper side of the back of the flat panel device 1, and the lower support shell 22 is rotated by the rotating mechanism 23 to provide support for the upright position of the flat panel device 1.

[0025] In specific implementation, the upper stop page 2321 and the lower stop page 2322 can be manufactured using powder metallurgy forming technology, and the main body thickness can be controlled between 0.8 and 1.2 mm. Powder metallurgy can ensure the dimensional accuracy and structural strength of the stop pages. The upper twist page 2311 and the lower twist page 2312 of the torsion page can be stamped using SUS304 material, and the main body thickness can be controlled between 0.5 and 0.8 mm. SUS304 material has excellent elasticity and corrosion resistance, and can maintain torsional deformation capacity for a long time.

[0026] The upper support shell 21 can be connected to the flat panel device 1 by adhesive bonding (applicable to flat panel devices 1 with factory-installed support frame 2), snap-fit, or magnetic connection: when adhesive bonding, epoxy resin adhesive can be used to ensure connection stability; snap-fit ​​can be achieved by setting buckles on the edge of the upper support shell 21 to snap-fit ​​with the slot or frame on the back of the flat panel device 1; magnetic connection can be achieved by using a magnet assembly to achieve adsorption and fixation.

[0027] When the rotating mechanism 23 is in its initial state, the upper hinge 2311 and the lower hinge 2312 of the torque hinge 231 remain parallel (e.g., Figure 3 As shown), the upper stop page 2321 and the lower stop page 2322 of the stop hinge 232 are also in a parallel state (as shown). Figure 7 As shown), at this time, the torque hinge 231 does not undergo torsional deformation, and the entire rotating mechanism 23 is in its natural state, allowing the flat panel device 1 and the support frame 2 to be stored in a fitted state (as shown). Figure 17 , 18 (As shown), it is easy to carry.

[0028] When an external force is applied to the lower support shell 22, driving it to rotate around the pivot 233, the main body of the upper hinge 2311 remains fixed with the upper support shell 21, while the main body of the lower hinge 2312 rotates with the lower support shell 22, resulting in relative torsional deformation between the upper hinge 2311 and the lower hinge 2312 (e.g., ...). Figure 4 As shown). When the rotating mechanism 23 reaches its maximum rotation state (i.e., when the stop hinge 232 reaches its maximum rotation state, as shown). Figure 8 As shown), the torque hinge 231 remains in an elastic deformation state (this can be achieved by selecting a torque hinge 231 of different materials or adjusting its thickness), ensuring that the torque hinge 231 can return to its initial shape after the external force is removed, while avoiding adjustment failure caused by permanent deformation. The first limiting structure 23211 and the second limiting structure 23221 of the stop hinge 232 cooperate to achieve angle limiting.

[0029] This invention utilizes the elastic deformation of the torsion hinge 231 to achieve stepless adjustment from 0° to the maximum rotation angle (e.g., 40°, 50°, 60°, etc.), allowing users to flexibly adjust the viewing angle of the tablet device 1 according to their posture and usage scenario (writing, watching movies). The continuous deformation characteristic of the torsion hinge 231 replaces discrete structures such as buckles and stops, enabling precise adjustment of the viewing angle. The torsion hinge 231 and stop hinge 232, made of metal, can be kept to a relatively thin thickness, meeting the design requirements of a lightweight, compact, and portable support frame.

[0030] Example 2: Furthermore, the first limiting structure 23211 is a first annular structure, and the second limiting structure 23221 is a second annular structure. The first annular structure and the second annular structure are respectively sleeved on the rotating shaft 233. The sum of the annular start and stop angles of the first annular structure and the annular start and stop angles of the second annular structure is less than 360°. When the first mating surface 232111 of the first annular structure is mated with the second mating surface 232211 of the second annular structure, the rotating mechanism 23 is in the maximum rotation state.

[0031] In specific implementation, the start and end angles of the fan ring (e.g.) Figure 9 The design of θ1 and θ2 in the figure can be based on the maximum rotation angle (e.g., Figure 9 The angle θ3 in the equation is determined. For example, if a maximum rotation angle of 40° is required (i.e., θ3 = 40°), the starting and ending angles of the first annular structure can be set to 160° (i.e., θ1 = 160°), and the starting and ending angles of the second annular structure can be set to 160° (i.e., θ2 = 160°). The sum of the two is 320°, and the maximum rotation angle is 360° - 320° = 40°. When the upper support shell 21 is connected to the flat plate device 1, the rotating mechanism 23 rotates. The first annular structure remains stationary with the upper stop 2321, and the second annular structure rotates with the lower stop 2322. When the first mating surface 232111 (one end face of the first annular structure) and the second mating surface 232211 (one end face of the second annular structure) are in contact with each other, the two annular structures form a mechanical block, restricting the rotating mechanism 23 from continuing to rotate.

[0032] Example 3: Furthermore, the number of torque hinges 231 is at least three, and a stop hinge 232 is provided between any two adjacent torque hinges 231. All torque hinges 231 and stop hinges 232 are connected through the same pivot 233, and all torque hinges 231 are interference-fitted to the pivot 233.

[0033] In practical implementation, for example, three torsion hinges 231 are set, and a stop hinge 232 is set between any two adjacent torsion hinges 231, forming an arrangement sequence of "torsion hinge 231-stop hinge 232-torsion hinge 231-stop hinge 232-torsion hinge 231". All torsion hinges 231 and stop hinges 232 are connected in series through the same rotating shaft 233. At this time, the three torsion hinges 231 can form a force-bearing whole through the interference fit with the same rotating shaft 233. When the rotating mechanism 23 rotates, the three upper torsion hinges 2311 are simultaneously fixed with the upper support shell 21, and the three lower torsion hinges 2312 rotate simultaneously with the lower support shell 22. Each torsion hinge 231 can bear similar torsional stress, avoiding deformation failure caused by excessive stress in a single torsion hinge 231.

[0034] More specifically, the interference fit between the torque hinge 231 and the rotating shaft 233 can be designed to be 0.05mm. For example, the diameter of the center hole of the torque hinge 231 is 2.95mm, and the diameter of the rotating shaft 233 is 3mm. During assembly, the rotating shaft 233 is pressed into the center hole of the torque hinge 231 using a press. The tight connection formed by the interference fit ensures that all torque hinges 231 can rotate synchronously with the rotating shaft 233.

[0035] Example 4: Furthermore, the upper support shell 21 is provided with a first positioning protrusion 211 and a second positioning protrusion 212, and the lower support shell 22 is provided with a third positioning protrusion 221 and a fourth positioning protrusion 222. The upper twist page 2311 is provided with a first positioning hole 23111 that is connected to the first positioning protrusion 211, and the lower twist page 2312 is provided with a second positioning hole 23121 that is connected to the third positioning protrusion 221. The top end page 2321 is provided with a third positioning hole 23212 that cooperates with the second positioning protrusion 212, and the bottom end page 2322 is provided with a fourth positioning hole 23222 that cooperates with the fourth positioning protrusion 222.

[0036] In practical implementation, the first positioning protrusion 211 and the second positioning protrusion 212 can be integrally molded with the upper support shell 21 using injection molding (the upper support shell 21 can be made of ABS plastic); the third positioning protrusion 221 and the fourth positioning protrusion 222 are the same size and can also be integrally molded with the lower support shell 22 using injection molding (the lower support shell 22 can be made of ABS plastic). During assembly, the first positioning protrusion 211 is inserted into the first positioning hole 23111, the second positioning protrusion 212 is inserted into the third positioning hole 23212, the third positioning protrusion 221 is inserted into the second positioning hole 23121, and the fourth positioning protrusion 222 is inserted into the fourth positioning hole 23222. This allows for the initial positioning of the torque hinge 231, the stop hinge 232, the upper support shell 21, and the lower support shell 22, ensuring the relative positional accuracy of each component.

[0037] Based on the initial positioning, epoxy resin adhesive can be used to bond and fix the torque hinge 231, the stop hinge 232 to the upper support shell 21, and the lower support shell 22. Specifically, epoxy resin adhesive with a shear strength ≥15MPa can be used to prevent the parts from falling off.

[0038] Example 5: Furthermore, a first deformation pad 234 and a second deformation pad 235 are connected between the upper support shell 21 and the lower support shell 22, and a rotating shaft 233 is disposed between the first deformation pad 234 and the second deformation pad 235.

[0039] In practice, both the first deformation pad 234 and the second deformation pad 235 can be made of PU material, which has good elasticity and wear resistance, as well as good aging resistance, and can provide good buffer protection for the key parts of the rotating mechanism 23, namely the rotating shaft 233 and its surrounding structures.

[0040] More specifically, the shape of the first deformable pad 234 can be designed to avoid the main body of the torque hinge 231 and the stop hinge 232, and the shape of the second deformable pad 235 can be designed to cover the torque hinge 231 and the stop hinge 232. Grooves adapted to the deformable pads can be provided on the inner sides of the upper support shell 21 and the lower support shell 22. The deformable pads are embedded in the grooves and bonded to the upper support shell 21 and the lower support shell 22 with adhesive backing. In specific assembly, firstly, the first deformable pad 234 is embedded in the grooves of the upper support shell 21 and the lower support shell 22. Then, the rotating shaft 233 and the torque hinge 231 and the stop hinge 232 are connected to the upper support shell 21 and the lower support shell 22 above the first deformable pad 234. Finally, the second deformable pad 235 is embedded in the grooves of the upper support shell 21 and the lower support shell 22 and covers the torque hinge 231 and the stop hinge 232.

[0041] Example 6: Furthermore, the upper support shell 21 is provided with at least two first embedding holes 213, and a first magnet 214 is embedded in each first embedding hole 213; The lower support shell 22 is provided with at least two second embedding holes 223, and a second magnet 224 is embedded in each second embedding hole 223; The sum of the magnetic attraction forces of all the first magnets 214 is greater than the sum of the magnetic attraction forces of all the second magnets 224.

[0042] In practical implementation, both the first magnet 214 and the second magnet 224 can be neodymium iron boron magnets, such as N52H neodymium iron boron magnets, with dimensions of 10×5×3mm (length×width×thickness), alternating N and S poles, a magnet embedding depth of 2.5mm (e.g., a 2.5mm embedding hole depth), and magnet dimensions slightly larger than the embedding hole dimensions, with an interference fit of 0.02mm. The magnetic attraction force can be adjusted by the number and arrangement of the magnets. The design that the sum of the magnetic attraction forces of all the first magnets 214 is greater than the sum of the magnetic attraction forces of all the second magnets 224 ensures a firm connection between the upper support shell 21 and the flat plate device 1 when the lower support shell 22 is flipped.

[0043] Example 7: Furthermore, the upper support shell 21 is provided with a first composite layer 215 on the side near the back of the flat device 1. The first composite layer 215 includes at least a first fiberglass plate 2151 and a first PU leather 2152. The lower support shell 22 has a second composite layer 225 on the side near the back of the flat panel device 1. The second composite layer 225 includes at least a second fiberglass plate 2251 and a second PU leather 2252.

[0044] In practice, the fiberglass plate can be first bonded to the side of the upper support shell 21 and the lower support shell 22 near the back of the flat panel device 1 with adhesive backing, ensuring that the fiberglass plate completely covers the components inside the support shell (the connection part of the first magnet 214, the second magnet 224, and the rotating mechanism 23); then the PU leather can be bonded to the outside of the fiberglass plate with adhesive backing, with the edge of the PU leather aligned with the edge of the upper support shell 21 and the lower support shell 22.

[0045] The fiberglass plate has high strength, which can prevent damage to the magnet and the connection parts of the rotating mechanism 23 caused by external impacts (such as drops). The soft surface of the PU leather can prevent scratches on the back of the tablet device 1 caused by direct friction between the support shell (upper support shell 21, lower support shell 22) material (such as ABS plastic) and the back of the tablet device 1. The anti-slip property of the PU leather can prevent the tablet device 1 from sliding on the support shell and improve the stability of the fixation. In addition, the flatness of the fiberglass plate can ensure that the PU leather fits flatly and closely to the back of the tablet device 1, avoiding uneven stress caused by local protrusions.

[0046] Example 8: Furthermore, the upper part of the upper support shell 21 is symmetrically provided with at least two third embedding holes 216 and a first through hole 217 communicating with the third embedding holes 216. Each third embedding hole 216 is embedded with a first rubber block 218, and the bottom of the first rubber block 218 protrudes from the first through hole 217. The bottom of the lower support shell 22 is symmetrically provided with at least two fourth embedding holes 226 and a second through hole 227 that communicates with the fourth embedding holes 226. A second rubber block 228 is embedded in each fourth embedding hole 226, and the bottom of the second rubber block 228 protrudes from the second through hole 227.

[0047] In practical implementation, the portion of the first rubber block 218 protruding from the first through hole 217 provides anti-slip and cushioning for the upper part of the upper support shell 21, and also protects components such as the rear camera mounted on the back of the tablet device 1. The portion of the second rubber block 228 protruding from the second through hole 227 can contact the desktop, increasing the friction between the support frame 2 and the desktop, preventing the support frame 2 from sliding, and improving support stability. During installation, the rubber blocks can be tightly inserted into the mounting holes using deformation, or the fixation can be enhanced through pads, adhesives, or other methods.

[0048] Example 9: Furthermore, the bottom of the lower support shell 22 is provided with a gripping groove 229.

[0049] In practical implementation, if the lower support shell 22 is made of metal (such as aluminum alloy), the gripping groove 229 can be formed by stamping; if the lower support shell 22 is made of plastic (such as ABS), the gripping groove 229 can be formed by injection molding. The design of the gripping groove 229 makes it easy for users to unfold the lower support shell 22 from the stored state: when the support frame 2 is in the stored state, the lower support shell 22 is close to the back of the tablet device 1, and the user can insert their fingertips into the gripping groove 229 to apply an outward pulling force, driving the lower support shell 22 to rotate around the rotating mechanism 23, unfolding it into the support state.

[0050] Example 10: Furthermore, when the support frame 2 supports the tablet device 1 on a horizontal surface and the rotating mechanism 23 is in its maximum rotation state, the angle between the plane where the screen 11 of the tablet device 1 is located and the normal to the horizontal plane is 15°~25°.

[0051] Preferably, when the support frame 2 supports the tablet device 1 on a horizontal surface and the rotating mechanism 23 is in its maximum rotation state, the angle between the plane where the screen 11 is located and the normal to the horizontal plane is 18°~22°.

[0052] More preferably, when the support frame 2 supports the tablet device 1 on a horizontal surface and the rotation mechanism 23 is in its maximum rotation state, the angle between the plane where the screen 11 is located and the normal to the horizontal plane is 20°.

[0053] In specific implementation, such as Figure 21 As shown, when the support frame 2 supports the tablet device 1 on a horizontal surface and the rotating mechanism 23 is in the maximum rotation state, the angle between the plane where the screen 11 of the tablet device 1 is located and the normal of the horizontal plane is controlled within a range of about 20°, so that the normal direction of the screen 11 is basically consistent with the user's line of sight, reducing the downward angle of the eyes and reducing visual fatigue.

[0054] Based on the above technical solutions of this utility model, the angle between the plane where the screen 11 is located and the normal to the horizontal plane can be accurately controlled by the rotation mechanism 23. For example, if the screen 11 of the tablet device 1 is parallel to the back body of the tablet device 1, and it is necessary to control the angle θ4 between the screen 11 and the normal to the horizontal plane to about 20°, a stop hinge 232 with a maximum rotation angle θ3 of 40° can be selected.

[0055] The assembly process of support frame 2 in the above technical solution can be referred to Figure 2 , 10 ~12, 15~16, for example: S1. (e.g.) Figure 2 (As shown) A first deformation pad 234 is bonded between the upper support shell 21 and the lower support shell 22; S2. (e.g.) Figure 10(As shown) A torque hinge 231 and a stop hinge 232 are installed between the upper support shell 21 and the lower support shell 22; S3. (e.g.) Figure 11 (As shown) A first magnet 214 is installed in the first mounting hole 213, and a second magnet 224 is installed in the second mounting hole 223; S4. (e.g.) Figure 12 (As shown) A second deformation pad 235 is bonded between the upper support shell 21 and the lower support shell 22; S5. (e.g.) Figure 15 (As shown) A first rubber block 218 is installed in the third embedding hole 216 and the first through hole 217, and a second rubber block 228 is installed in the fourth embedding hole 226 and the second through hole 227. S6. (e.g.) Figure 16 As shown, the first composite layer 215 and the second composite layer 225 are installed, and the first PU leather 2152 / second PU leather 2252 are bonded to the first fiberglass plate 2151 / second fiberglass plate 2251 by adhesive backing.

Various modifications and variations can be made to this utility model by those skilled in the art.
