Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and more specifically, to a folding bracket and a protective case for electronic devices. Background Technology

[0002] A stand is a device specifically designed to support portable electronic devices, aiming to free up the user's hands by placing the device at an angle on a desktop.

[0003] Existing brackets generally include a mounting base and a support plate hinged to the mounting base. The mounting base is installed on the phone case or fixed to the back of the electronic device. When the electronic device needs to be tilted on the table, the support plate opens at a certain angle along the hinge axis to support the electronic device.

[0004] However, with the emergence of foldable screen devices, the size of portable electronic devices is constantly increasing. The hinge points between the support plate and the mounting base need to withstand greater torque. Even slight vibrations on the desktop can cause the device's center of gravity to shift, leading to loosening of the support plate, tilting of the device, or even the entire device tipping over. Especially when users operate the device (such as clicking the screen or swiping the interface), the applied external force will further exacerbate the shaking of the support structure, seriously affecting the safety and user experience.

[0012] In an optional embodiment, the resilient snap-fit ​​element includes a spring and a snap-fit ​​element; The snap-fit ​​component is movably disposed within the mounting slot and extends partially into the recess. The elastic snap-fit ​​element is disposed in the mounting groove and abuts against the snap-fit ​​element, configured to provide elastic force to the snap-fit ​​element in the direction of the cylindrical boss, so that the snap-fit ​​element is partially snapped between two adjacent protrusions; The connecting plate rotates relative to the fixed base, and the protruding teeth can push the snap-fit ​​piece out of the gap between the corresponding two protruding teeth. The restoring force of the spring can make the snap-fit ​​piece snap into the gap between the currently corresponding two protruding teeth.

[0013] In an optional embodiment, a thickened boss is provided on the side of the connecting plate away from the fixed base, and the groove extends into the thickened boss.

Detailed Implementation

[0020] Existing brackets generally include a mounting base and a support plate hinged to the mounting base. The mounting base is installed on the phone case or fixed to the back of the electronic device. When the electronic device needs to be tilted on the table, the support plate opens at a certain angle along the hinge axis to support the electronic device.

[0021] However, with the emergence of foldable screen devices, the size of existing portable electronic devices continues to increase. The hinge points between the support plate and the mounting base need to withstand greater torque. Even slight vibrations on the desktop can cause the device's center of gravity to shift, leading to loosening of the support plate, tilting of the device, or even the entire device tipping over. Especially when users operate the device (such as clicking the screen or swiping the interface), the applied external force will further exacerbate the shaking of the support structure, seriously affecting safety and user experience.

[0022] To address the aforementioned issues, this invention provides a foldable protective case for electronic devices that improves support stability, thereby mitigating instability during desktop vibrations or user operation.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0028] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0029] The following describes in detail the overall structure, working principle, and technical effects of the folding bracket and electronic device protective case provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 to 10 This embodiment provides a protective case 300 for an electronic device. The protective case 300 can be a mobile phone case 310, such as a candybar phone case 310 or a folding phone case 310. The protective case 300 can also be a tablet case 310 or a case 310 for other portable electronic devices. It can be fitted onto the back of the electronic device to provide protection and support.

[0031] Furthermore, the electronic device protective case 300 includes a protective case 310 and a folding bracket 100. The folding bracket 100 is mounted on the back of the protective case 310 to support the electronic device.

[0032] It should be noted that this embodiment does not limit the specific shape and structure of the protective shell 310, which can be adjusted according to the shape of the terminal electronic device.

[0033] Please refer to Figures 1 to 10 In this embodiment, the folding bracket 100 includes a fixing component 110, a hinge plate 150, and a support plate 170. The fixing component 110 is connected to the protective shell 310. One end of the hinge plate 150 is hinged to the fixing component 110, and the other end is hinged to the support plate 170. The folding bracket 100 has a stacked storage state with the fixing component 110, the hinge plate 150, and the support plate 170 stacked, a supported state with the hinge plate 150 rotating relative to the fixing component 110 by a preset angle, and a supported state with the support plate 170 rotating relative to the hinge plate 150 by a preset angle. In the supported state, the sidewall of the support plate 170 is used for supporting the plane abutment.

[0034] In this embodiment, the support frame is configured with a fixed component 110, a hinge plate 150, and a support plate 170 that are hinged sequentially. When the folding bracket 100 is in the supported state, the hinge plate 150 rotates a preset angle relative to the fixed component 110, and the support plate 170 rotates a preset angle relative to the hinge plate 150, forming an overall roughly "Z"-shaped support on the back of the electronic device. This significantly increases the contact area with the supporting surface, thereby improving the stability of the support and significantly mitigating the problem that slight vibrations of the desktop can cause the device's center of gravity to shift, leading to loosening of the support plate 170, tilting of the device, or even the entire device tipping over. It also provides sufficient support force when the user operates the device, reducing the problem of electronic device wobbling and thus improving the user experience. When in the storage state, the fixed component 110, hinge plate 150, and support plate 170 are stacked, which also saves space.

[0035] Of course, in some embodiments of this application, the folding bracket 100 can also be used alone. For example, the fixing component 110 can be directly attached to a suitable position on the back of the electronic device using double-sided adhesive. The electronic device can be a mobile phone, tablet, computer, handheld engineering device, etc.

[0036] Please refer to Figures 1 to 10 Furthermore, the folding bracket 100 also includes a first hinge 180, which has a first pivot 181. The support plate 170 is elongated and has a length direction and a width direction. The support plate 170 is connected to the hinge plate 150 via the first hinge 180, and the first pivot 181 is parallel to the width direction. When the folding bracket 100 is in the supported state, one sidewall of the support plate 170 in the width direction is used to abut against the support plane.

[0037] In this embodiment, through the above connection relationship, when the folding bracket 100 is in the supported state, one side wall of the support plate 170 in the width direction (the long side of the support plate 170) is used to abut against the support plane, so that the support effect and the stability of the support are better.

[0038] Furthermore, the four corners of the support plate 170 are all provided with rounded chamfers.

[0039] In this embodiment, the support plate 170 is provided with a receiving groove 171 for accommodating the hinge plate 150. When the folding bracket 100 is in the stored state, the hinge plate 150 is accommodated in the receiving groove 171 so that the support plate 170 abuts against the fixing component 110.

[0040] In this embodiment, by providing a receiving groove 171 in the support plate 170, the hinge plate 150 can be received in the receiving groove 171 when the folding bracket 100 is in the storage state, thereby forming a two-layer stacked structure of the fixing component 110, the hinge plate 150 and the support plate 170, so that the overall thickness of the folding bracket 100 is thinner when it is in the storage state.

[0041] Please refer to Figures 1 to 10 Furthermore, the thickness of the hinge plate 150 is the same as the thickness of the support plate 170. The receiving groove 171 extends through the support plate 170, and when the folding bracket 100 is in the stored state, the hinge plate 150 is embedded in the receiving groove 171. The shape of the receiving groove 171 matches the shape of the hinge plate 150, and is slightly larger than the hinge plate 150, thereby making it easier to receive the hinge plate 150 in the receiving groove 171.

[0042] Of course, in other embodiments of this application, the thicknesses of the hinge plate 150 and the support plate 170 may also be different. When the thickness of the hinge plate 150 is thinner than the thickness of the support plate 170, the receiving groove 171 may not be through, as long as it can accommodate the hinge plate 150 inside.

[0043] Please refer to Figures 1 to 10 Furthermore, after the support plate 170 rotates a certain angle relative to the hinge plate 150 at the first hinge 180, the support plate 170 can abut against the hinge plate 150 to limit the maximum rotation angle between them. The maximum rotation angle can be set according to requirements. In this embodiment, the maximum rotation angle between the support plate 170 and the hinge plate 150 is 130°. Of course, in other embodiments of this application, the maximum rotation angle can be changed by adjusting the setting position of the first hinge 180.

[0044] Secondly, the two connecting parts of the first hinge 180 are fixed to the inner sides of the support plate 170 and the hinge plate 150, respectively, so that the first hinge can be folded inside when in the storage state, thus making the whole more aesthetically pleasing.

[0045] Furthermore, both the inner surfaces of the hinge plate 150 and the support plate 170 are recessed with mounting grooves 172, and the mounting grooves 172 are recessed with locking platforms 174. The two hinge parts of the first hinge 180 are respectively installed in the mounting grooves 172 of the hinge plate 150 and the support plate 170, and are locked with the locking platforms 174. A decorative layer 173 is affixed to the outer side of the hinge part, which can cover the hinge part of the hinge, thereby improving the aesthetics.

[0046] Please refer to Figures 1 to 10 In this embodiment, the folding bracket 100 further includes a second hinge 190, through which the hinge plate 150 and the fixing assembly 110 are hinged. The second hinge 190 has a second pivot 191. The second pivot 191 is parallel to the first pivot 181.

[0047] In this embodiment, the hinge plate 150 and the fixing component 110 are connected by the second hinge 190, which is more conducive to rotational connection and support.

[0048] Furthermore, one end of the hinge plate 150 is hinged to one end of the fixing assembly 110 via a second hinge 190.

[0049] Specifically, after the hinge plate 150 rotates a certain angle relative to the fixed component 110 at the second hinge 190, the hinge plate 150 can abut against the fixed component 110 to limit the maximum rotation angle between them. The maximum rotation angle can be set according to requirements. In this embodiment, the maximum rotation angle between the fixed component 110 and the hinge plate 150 is 120°. Of course, in other embodiments of this application, the maximum rotation angle can be changed by adjusting the setting position of the second hinge 190 and changing the chamfers corresponding to the hinge plate 150 and the fixed component 110.

[0050] Please refer to Figures 1 to 10 Furthermore, one of the two connecting parts of the second hinge 190 is fixed to the outside of the fixing assembly 110, and the other is fixed to the inside of the hinge plate 150. This allows it to fold inwards when in storage, making the overall appearance more aesthetically pleasing. Secondly, the fixing method of the second hinge 190 is basically the same as the assembly method of the first hinge 180, and will not be described in detail here.

[0051] It should be noted that both the first hinge 180 and the second hinge 190 are hinges with damping. They can be hinges in the form of flat shafts or other existing forms. This embodiment does not limit the specific structure of the first hinge 180 and the second hinge 190. Furthermore, in some other embodiments of this application, the hinge between the hinge plate 150 and the support plate 170, as well as the hinge between the hinge plate 150 and the fixing assembly 110, can also be directly hinged using flat shafts.

[0052] Furthermore, the fixing assembly 110 includes a fixing base 111 and a connecting plate 112. The fixing base 111 is used to connect to an electronic device or a protective housing 310. The connecting plate 112 is rotatably connected to the fixing base 111, and a hinge plate 150 is hinged to the fixing base 111. When the folding bracket 100 is in the stored state, both the hinge plate 150 and the support plate 170 are stacked on the connecting plate 112.

[0053] In this embodiment, the fixed assembly 110 is provided with a rotatably connected fixed base 111 and connecting plate 112, and the hinge plate 150 is hinged to the connecting plate 112. This allows the connecting plate 112, hinge plate 150 and support plate 170 to rotate relative to the fixed base 111, thus adapting to different placement methods of electronic devices and providing a better user experience.

[0054] Please refer to Figures 1 to 10 Furthermore, the support plate 170 protrudes outward relative to the periphery of the connecting plate 112 to form a gripper.

[0055] In this embodiment, the support plate 170 protrudes outward relative to the periphery of the connecting plate 112, which forms a gripper groove 113 on the outer periphery of the connecting plate 112 in the height direction to form a gripper. This makes it easy for the user to hold the support plate 170 stably and open the folding bracket 100 from the storage state to the support state.

[0056] Furthermore, the connecting plate 112 is elongated, and its dimensions in both the length and width directions are smaller than those of the support plate 170.

[0057] Please refer to Figures 1 to 10 Furthermore, the fixing assembly 110 also includes a resilient snap-fit ​​member 114. The fixing base 111 has a cylindrical boss 115 protruding towards the connecting plate 112, and a plurality of protruding teeth 116 are spaced apart on the outer periphery of the boss. The connecting plate 112 has a groove 117 and a mounting groove 118 communicating with the groove 117 on the side near the fixing base 111. The cylindrical boss 115 is rotatably mounted in the groove 117. The resilient snap-fit ​​member 114 is installed in the mounting groove 118 and extends into the groove 117 to snap between two adjacent protruding teeth 116. When the connecting plate 112 rotates relative to the fixing base 111, the protruding teeth 116 allow the resilient snap-fit ​​member 114 to deform and move out, snapping between the corresponding two protruding teeth 116.

[0058] This embodiment, by incorporating an elastic snap-fit ​​member 114, facilitates the relative fixation of the connecting plate 112 and the fixing seat 111 at different angles, thereby improving the stability of the support. A clicking sound will be heard when rotating.

[0059] It should be noted that the fixed base 111 is roughly gear-shaped, and a snap-fit ​​groove 119 is formed between any two adjacent protrusions 116, and the elastic snap-fit ​​member 114 snaps into one of the snap-fit ​​grooves 119.

[0060] In one embodiment of this application, the elastic snap-fit ​​member 114 includes a spring 120 and a snap-fit ​​member 121. The snap-fit ​​member 121 is movably disposed within a mounting groove 118 and partially extends into a recess 117. The spring 120 is disposed within the mounting groove 118 and abuts against the snap-fit ​​member 121 to provide a spring force to the snap-fit ​​member 121 in the direction of the cylindrical boss 115, so that the snap-fit ​​member 121 is partially engaged between two adjacent protrusions 116. When the connecting plate 112 rotates relative to the fixed base 111, the protrusions 116 can push the snap-fit ​​member 121 out of the gap between the corresponding two protrusions 116, and the restoring force of the spring 120 can cause the displaced snap-fit ​​member 121 to engage between the currently corresponding two protrusions 116.

[0061] In this embodiment, the snap-fit ​​component 121 is configured as a spring 120 and a snap-fit ​​component 121. The spring 120 provides the snap-fit ​​force, which makes the structure simple and easy to implement.

[0062] Please refer to Figures 1 to 10 In this embodiment, the mounting groove 118 includes a rectangular limiting groove 122 and a trapezoidal connecting groove 123. The small end of the trapezoidal connecting groove 123 connects to the recess 117, and the large end of the trapezoidal connecting groove 123 connects to the rectangular limiting groove 122. A blind hole 124 is provided on the bottom wall of the rectangular limiting groove 122. The snap-fit ​​member 121 is formed by bending a metal sheet or by injection molding plastic. The general shape of the snap-fit ​​member 121 includes a V-shaped snap-fit ​​portion 125 and limiting portions 126 connected to both sides of the top of the V-shape, with the limiting portions 126 extending outward to both sides. The snap-fit ​​member 121 is installed in the trapezoidal connecting groove, while the limiting portions 126 are located in the rectangular groove. A spring 120 is installed in the blind hole 124 and abuts against the snap-fit ​​member 121. Under the action of the spring 120, one end of the tip of the snap-fit ​​member 121 extends into the recess 117 and snaps into the snap-fit ​​groove 119 between the two protruding teeth 116. The rotation of the connecting plate 112 causes the locking member 121 and the spring 120 to rotate. The protruding teeth 116 act as guides, compressing the locking member 121 and causing it to move out of the locking groove 119 between the two protruding teeth 116. Under the action of the spring 120, it engages in the next locking groove 119 in the rotational direction, thus producing a clicking sound. The trapezoidal connecting groove 123 cooperates with the V-shaped locking part 125 to guide movement, while the limiting part 126 limits the length of the locking part 125 that extends into the groove.

[0063] Of course, in other embodiments of this application, the shape of the snap-fit ​​121 may also be U-shaped, triangular or other shapes.

[0064] Furthermore, a sealing plate 127 is also provided on the outside of the mounting groove 118. The sealing plate 127 can be fixed by adhesive and can seal the opening of the mounting groove 118 to prevent the snap fastener 121 and the spring 120 from falling out.

[0065] The number of flexible snap-fit ​​connectors 114 is one, but of course, two or more symmetrical ones can also be set.

[0066] Of course, in some embodiments of this application, the spring 120 and the snap-fit ​​121 are replaced by a spring sheet structure.

[0067] Furthermore, a thickened boss 128 is provided on the side of the connecting plate 112 away from the fixed base 111, and the groove 117 extends into the thickened boss 128. A clearance groove 151 is provided on the side of the hinge plate 150 that is stacked with the connecting plate 112, and the clearance groove 151 corresponds to the thickened boss 128. When the folding bracket 100 is in the storage state, the thickened boss 128 is located in the clearance groove 151.

[0068] In this embodiment, the thickened boss 128 and the clearance groove 151 can reduce the thickness of the connecting plate 112, and further reduce the thickness in the storage state.

[0069] Please refer to Figures 1 to 10 Furthermore, the fixing assembly 110 also includes a screw 129. The fixing seat 111 has a countersunk hole 130 on the side away from the cylindrical boss 115, concentrically corresponding to and penetrating the cylindrical boss 115. A fixing post 131 is provided at the center of the groove 117, and the fixing post 131 is inserted into the countersunk hole 130. The screw 129 is installed in the countersunk hole 130 and connected to the fixing post 131.

[0070] The connection method of the screw 129 described above can better achieve the rotational connection between the two.

[0071] Please refer to Figures 1 to 10 Furthermore, one of the top wall of the cylindrical boss 115 and the bottom wall of the groove 117 is provided with an arc-shaped groove 132, and the other is provided with a limiting post 133. The limiting post 133 is inserted into the arc-shaped groove 132. When the connecting plate 112 rotates relative to the fixed base 111, the limiting post 133 rotates along the arc-shaped groove 132. The side walls on both sides of the arc-shaped groove 132 in the length direction can abut against the limiting post 133, which can limit the angle of relative rotation between the two. Secondly, at least two positioning posts 134 are protruding on the side of the mounting base away from the boss. The protective shell 310 is provided with corresponding positioning holes. The positioning posts 134 are inserted into the positioning holes to limit the relative rotation between the two.

[0072] Specifically, the limiting post 133 protrudes from the bottom wall of the mounting groove 118, and the arc-shaped groove 132 is recessed into the top wall of the cylindrical boss 115. The rounded corners corresponding to the arc-shaped groove 132 can be set according to actual needs.

[0073] In summary, the support frame of this application comprises a fixed component 110, a hinge plate 150, and a support plate 170 that are hinged sequentially. When the folding bracket 100 is in the supported state, the hinge plate 150 rotates a preset angle relative to the fixed component 110, and the support plate 170 rotates a preset angle relative to the hinge plate 150, forming an approximate "Z" shape to support the back of the electronic device. This significantly increases the contact area with the desktop, thereby improving the stability of the support. It also addresses the issue that slight vibrations of the desktop can cause the device's center of gravity to shift, leading to loosening of the support plate 170, tilting of the device, or even the entire device tipping over. Furthermore, it provides sufficient support when the user operates the device (such as clicking the screen or swiping the interface), reducing the problem of electronic device wobbling and improving the user experience. When folded, the fixed component 110, hinge plate 150, and support plate 170 are stacked, saving space.

[0074] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
