Description

Technical Field

[0001] This application relates to the field of brackets, and relates to an electronic device bracket. Background Art

[0002] With the popularization of electronic devices such as laptop computers, brackets for supporting these electronic devices such as laptop computers are widely used. On the one hand, the laptop computer bracket helps with the heat dissipation of the laptop computer. On the other hand, due to the adjustability of its structure, it helps to meet the usage needs of different users. The inclination angle of the bracket can be adjusted to meet the support needs at different angles.

[0003] However, for the computer brackets in the prior art, when folding, due to the limitation of their structure, the folding is not convenient. Especially for those brackets with multiple legs and support plates, each part needs to be folded in sequence, which is inconvenient to operate, time-consuming and laborious. Moreover, the volume of some brackets is still large after folding, which is not conducive to carrying and storing, bringing inconvenience to daily use. Utility Model Content

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0052] Embodiment 1

[0053] As Figure 1 shown, this embodiment provides an electronic device bracket, which includes a connecting frame and a plurality of supporting frames installed on the connecting frame. Among them, a first supporting frame 11 and a second supporting frame 12 are installed at one end of the connecting frame, and a bracket is installed at the other end of the connecting frame.

[0054] The bracket can be an independent supporting frame or two supporting frames like the first supporting frame 11 and the second supporting frame 12, such as a third supporting frame 13 and a fourth supporting frame 14. Among them, the first supporting frame 11 and the second supporting frame 12 are used to support the back of the electronic device, and the third supporting frame 13 and the fourth supporting frame 14 are used to support and hold the bottom of the electronic device to prevent the electronic device from falling.

[0055] The electronic device bracket provided in this embodiment can be used for supporting devices such as laptop computers, and of course can also be used for supporting other tablet devices.

[0056] In this embodiment, the first supporting frame 11, the second supporting frame 12, the third supporting frame 13, and the fourth supporting frame 14 of the electronic device bracket are respectively rotatably connected to the connecting frame. In this way, the first supporting frame 11, the second supporting frame 12, the third supporting frame 13, and the fourth supporting frame 14 can respectively rotate to approach the connecting frame to form a folded state, which is convenient for carrying.

[0057] Further, as Figure 9 shown, the connecting frame of this embodiment is composed of a first connecting frame 21 and a second connecting frame 22. The first connecting frame 21 and the second connecting frame 22 are connected by a hinge 23. The first connecting frame 21 and the second connecting frame 22 rotate through the hinge 23 to fold the connecting frame, further reducing the volume of the electronic device bracket and making it more convenient to carry. For the fully folded state of this embodiment, please refer to Figure 14 .

[0058] As Figure 9As shown in the figure, adjusting components are respectively provided on the first support frame 11 and the second support frame 12 of this embodiment; the adjusting component includes an adjusting leg 51, an adjusting plate 52, and a plurality of fixed baffles 53 provided on the surfaces of the first support frame 11 and the second support frame 12. One end of the adjusting leg 51 is connected to the first support frame 11 or the second support frame 12 through a rotating shaft, so that the adjusting leg 51 can rotate to one side of the first support frame 11 or the second support frame 12 to reach an unfolded state; one end of the adjusting plate 52 is connected to the adjusting leg 51 through a rotating shaft, and the other end of the adjusting plate 52 can be adjusted and abutted against different fixed baffles 53, so that different included angles are formed between the adjusting leg 51 and the first support frame 11 or the second support frame 12, thereby adjusting the distance between the end of the adjusting leg 51 and the first support frame 11 or the second support frame 12, so that the electronic device bracket can have different inclination angles when placed to meet different needs of users.

[0059] As a further improvement, in this embodiment, as Figure 9 shown, support plates 40 extending toward the side of the adjusting leg 51 are respectively provided on the first support frame 11 and the second support frame 12, and the extending length of the support plates 40 is less than the maximum distance between the end of the adjusting leg 51 and the first support frame 11 or the second support frame 12. Such a design enables the support plate 40 to contact the tabletop when the bracket is placed on the table before the adjusting leg 51 is unfolded, so that the bracket has an initial inclination angle. This inclination angle can not only meet the user's need for the bracket to be inclined at a small angle, but also reserve space at the bottom of the first support frame 11 or the second support frame 12 before the adjusting leg 51 is unfolded, thereby facilitating the fingers to reach in and contact the adjusting leg 51, and the adjusting leg 51 can be unfolded without lifting the entire bracket, which provides convenience for the unfolding adjustment of the adjusting leg 51.

[0060] It is worth mentioning that for the electronic device bracket of this embodiment, the first support frame 11 and the second support frame 12 are connected through a first gear assembly, so that the first support frame 11 and the second support frame 12 can rotate synchronously to achieve the effect of being unfolded or folded simultaneously.

[0061] Specifically, as Figure 1 and Figure 2 shown, an accommodation cavity is provided inside one end of the first connecting frame 21 of this embodiment, and a second cover plate 215 covering the accommodation cavity is provided on the surface of the first connecting frame 21. The first gear assembly is limited in the accommodation cavity and can rotate relative to the first connecting frame 21; the first support frame 11 and the second support frame 12 are respectively connected to the gear units in the first gear assembly to achieve the effect of synchronous rotation.

[0062] In this embodiment, the first support frame 11 and the second support frame 12 can be synchronously moved to a relatively open state or a relatively folded state through the first gear assembly; in the relatively open state, the first support frame 11 and the second support frame 12 are unfolded in a straight line, or the first support frame 11 and the second support frame 12 are unfolded to form a certain angle. At this time, the first support frame 11 and the second support frame 12 are respectively away from the connecting frame and form an angle with the connecting frame. This unfolded state is used to support the electronic device.

[0063] In the relatively folded state, the first support frame 11 and the second support frame 12 approach and converge towards the connecting frame. At this time, the first support frame 11, the second support frame 12, and the connecting frame are parallel to each other. This folded state has a smaller volume and is convenient for carrying and storing.

[0064] In the electronic device bracket of this embodiment, the first support frame 11 and the second support frame 12 of the electronic device are synchronously unfolded and folded through the first gear assembly, which greatly improves the opening and folding speed of the bracket, reduces the operation steps, and improves the convenience.

[0065] In one embodiment, as Figure 2 shown, the first gear assembly includes a first gear 31 and a second gear 32. The first gear 31 and the second gear 32 are meshed with each other, and the first gear 31 and the second gear 32 are respectively connected to the first support frame 11 and the second support frame 12 in a one-to-one correspondence. When the first support frame 11 moves, the first support frame 11 rotates to drive the first gear 31 to rotate, and the first gear 31 drives the second gear 32 to rotate, so that the second support frame 12 follows and rotates.

[0066] Due to the meshing relationship between the first gear 31 and the second gear 32, the first support frame 11 and the second support frame 12 have opposite movement directions, so as to adjust the angle between the first support frame 11 and the second support frame 12 and realize the synchronous unfolding or folding of the first support frame 11 and the second support frame 12.

[0067] Based on the same principle, in some embodiments, four or six gears can also be used, as long as it is limited that the first support frame 11 and the second support frame 12 can rotate synchronously and have opposite rotation directions. Therefore, the number of gears in the first gear set in this embodiment is not uniquely limited.

[0068] In this embodiment, certain improvements have been made to the self-structure and installation structure of the first gear 31 and the second gear 32.

[0069] As Figure 3 and Figure 4 shown, in this embodiment, the accommodating cavity includes two gear grooves 211 and two mounting holes 212. Among them, the first gear 31 and the second gear 32 respectively correspond to a gear groove 211 and a mounting hole 212 in a one-to-one correspondence.

[0070] The two gear slots 211 are connected to ensure that the first gear 31 and the second gear 32 in the two gear slots 211 can mesh. Of course, the two gear slots 211 can also be a large slot as long as it can accommodate two meshing gears.

[0071] The two mounting holes 212 are respectively arranged at the bottom of the two gear slots 211 to communicate the accommodation cavity with the outside of the connecting frame, so as to facilitate the connection of the first gear 31 and the second gear 32 with the corresponding first support frame 11 and second support frame 12.

[0072] In one embodiment, the mounting holes 212 can be used to mount the first gear 31 and the second gear 32 to ensure that the first gear 31 and the second gear 32 can rotate stably in the gear slots 211.

[0073] Alternatively, the mounting holes 212 are only used for the passage between the gear and the support frame.

[0074] As Figure 5 shown, the first gear 31 and the second gear 32 of this embodiment respectively include a gear body 311 and a mounting portion 312, and the mounting portion 312 is arranged on the side surface of the gear body 311. The mounting hole 212 is a circular hole or at least partially an arc surface, the mounting portion 312 is a circular boss or cylindrical structure with a certain thickness, and the outer circumferential wall of the mounting portion 312 is correspondingly mounted inside the circumferential wall of the mounting hole 212, so that the first gear 31 and the second gear 32 can rotate in the mounting hole 212.

[0075] Of course, in some embodiments, the shape of the inner wall of the gear slot 211 can also be limited, for example, it is a circular inner wall, so that the first gear 31 and the second gear 32 can rotate stably in the gear slot 211. The thickness of the gear slot 211 can also be further limited so that it is just slightly larger than the thickness of the gear body 311. In this way, the gear body 311 is limited in the gear slot 211 to prevent the first gear 31 and the second gear 32 from shaking or shifting.

[0076] In this embodiment, the mounting holes 212 and the mounting portions 312 respectively have a certain thickness to increase the contact area between the two and ensure the rotational stability of the first gear 31 and the second gear 32.

[0077] Preferably, the thickness of the mounting portion 312 can be greater than that of the mounting hole 212, so that the first gear 31 and the second gear 32 can extend out of the surface of the first connecting frame 21, thereby facilitating the connection with the first support frame 11 and the second support frame 12.

[0078] As Figure 6As shown, a plurality of connecting columns 313 are provided on the mounting portions 312 of the first gear 31 and the second gear 32. Correspondingly, connecting holes 111 are provided on the first support frame 11 and the second support frame 12. The connecting columns 313 can be inserted into the connecting holes 111 for connection, so that the first support frame 11 and the second support frame 12 are respectively fixedly connected to the corresponding first gear 31 or second gear 32.

[0079] A detachable first cover plate 112 is provided on the back of the first support frame 11 and the second support frame 12 corresponding to the connecting holes 111. By removing the first cover plate 112, it is convenient for the first support frame 11 and the second support frame 12 to be connected to the first gear 31 and the second gear 32.

[0080] Furthermore, as Figure 7 and Figure 8 shown, screw holes 114 are provided at corresponding positions on the first support frame 11 and the second support frame 12. The mounting portion 312 can be connected to the first support frame 11 and / or the second support frame 12 through screws 33 respectively to improve the connection strength between the support frame and the gear. Specifically, the screws 33 penetrate through the gear body 311 and the mounting hole 212 from one side of the gear body 311 and are connected to the first support frame 11 and the second support frame 12.

[0081] Of course, in order to simplify the structure, the connecting columns 313 and the connecting holes 111 can also be removed, and the first support frame 11 and the second support frame 12 can be directly connected to the first gear 31 and the second gear 32 through screws 33 as well.

[0082] In this application, the first gear 31, the second gear 32 and the support frame can be fixedly connected by screws 33. In this way, when the first support frame 11 is driven to rotate by force, the gear body 31 connected thereto can be driven to rotate, and the gear body 32 is driven by the meshing force to drive the second support frame 12 to rotate synchronously. In some other embodiments, the first gear 31, the second gear 32 and the support frame are movably connected by screws 33. In this way, the first gear 31 and the second gear 32 can rotate relative to the support frame around the screws 33. At this time, the gear bodies 311 are driven by the limiting columns 113 to mesh with each other to achieve synchronous transmission.

[0083] As Figure 5 shown, in one embodiment, at least part of the circumferential surface of the gear body 311 has an arc surface 3112 and teeth 3111 protruding from the arc surface 3112. It can be understood that on the first gear 31 and the second gear 32, there are parts where the teeth 3111 are not provided, and the parts where the teeth 3111 are not provided are arc surfaces. The first gear 31 and the second gear 32 have the same structure, and their teeth 3111 are meshed with each other. Such a design makes the first gear 31 and the second gear 32 can only rotate within an appropriate range.

[0084] Meanwhile, a gear limiting structure is formed at the edge of the gear groove 211 to block the tooth 3111, thereby limiting the rotation range of the first gear 31 and the second gear 32.

[0085] In this embodiment, the gear limiting structure may be a part of the gear groove 211. The shape of the gear groove 211 may be irregular. The gear limiting structure is a structure protruding from the inner surface of the gear groove 211 to limit the first gear 31 and the second gear 32. The gear limiting structure may also be a separate structure installed inside the gear groove 211. The gear limiting structure is detachably installed at a set position on the inner surface of the gear groove 211 to limit the first gear 31 and the second gear 32.

[0086] This set position corresponds to the maximum position where the first support frame 11 and the second support frame 12 are unfolded or the position where the first support frame 11 and the second support frame 12 are folded and brought together. That is, when the first support frame 11 and the second support frame 12 are unfolded to the maximum position, the gear limiting structure exactly blocks the edge tooth 3111. And when the first support frame 11 and the second support frame 12 are folded to the together position, the gear limiting structure exactly blocks the tooth 3111 on the other side, thereby limiting the rotation range of the first support frame 11 and the second support frame 12.

[0087] Specifically, as Figure 4 and Figure 7 shown, in one embodiment, the gear limiting structure may be an arc-shaped strip 214 installed on the inner side wall of the gear groove 211, or an arc-shaped strip 214 integrally formed with the gear groove 211. The two ends of the arc-shaped strip 214 are located on the moving path of the tooth 3111. By blocking the movement of the tooth 3111 with the two ends of the arc-shaped strip 214, the limiting effect is achieved.

[0088] In one embodiment, a clamping structure is provided between the arc-shaped strip 214 and the gear body 311. The gear body 311 can rotate to be clamped with the arc-shaped strip 214 through the clamping structure. The clamping of the clamping structure can provide a certain resistance when the first support frame 11 and the second support frame 12 rotate to the in-place position, prevent the first support frame 11 and the second support frame 12 from rotating easily, and can also play a certain feedback role when rotating to the in-place position to remind the user that the rotation of the support frame has reached the in-place position.

[0089] In one embodiment, the clamping structure may be a clamping block 3113 and a clamping groove 2142.

[0090] As Figure 4 shown, the arc-shaped strip 214 has an inner arc surface 2141 facing and approaching the arc surface 3112, and a clamping groove 2142 is provided on the inner arc surface 2141.

[0091] Correspondingly, as Figure 5As shown in the figure, a clamping block 3113 is provided on the arc surface 3112 of the gear body 311. The dimension that the clamping block 3113 protrudes from the arc surface 3112 is greater than the gap between the arc surface 3112 and the inner arc surface 2141. When the clamping block 3113 rotates with the gear body 311, the clamping block 3113 abuts against the inner arc surface 2141, and is clamped with the clamping groove 2142 when the tooth 3111 contacts the end of the arc-shaped strip 214.

[0092] Such a design is to enable the first support frame 11 and the second support frame 12 to have a certain clamping resistance when rotating to the target position, and can prevent the first support frame 11 and the second support frame 12 from being easily rotated in the target position state. Therefore, the positions of the clamping groove 2142 and the clamping block 3113 should be designed at the maximum unfolding position and the folding position of the first support frame 11 and the second support frame 12. Correspondingly, two clamping grooves 2142 should be provided on the arc-shaped strip 214, respectively corresponding to the maximum unfolding position and the folding position of the first support frame 11 and the second support frame 12.

[0093] As Figure 5 shown in the figure, an avoidance hole 3114 is provided at the position of the gear body 311 close to the clamping block 3113. The gear body 311 should be made of an elastic material, or at least the position of the clamping block 3113 has elasticity. In this way, when rotating, the clamping block 3113 can be squeezed by the inner arc surface 2141 and shrink towards the avoidance hole 3114 to ensure the normal operation of the gear.

[0094] Embodiment 2

[0095] This embodiment provides an electronic device bracket, which is the same as that mentioned in the above embodiment. The difference is that the above embodiment limits the gear by setting the arc-shaped strip 214 to resist the tooth 3111, while this embodiment provides another limiting method.

[0096] Of course, the limiting method of this embodiment can also be a supplementary solution to the above limiting structure, and can coexist with the above arc-shaped strip 214 to limit the gear.

[0097] As Figure 4 and Figure 5 shown in the figure, an arc-shaped limiting hole 213 extending along the rotation direction of the gear body 311 is provided on the surface of the first connecting frame 21. At the same time, a positioning hole 3115 is provided on the gear body 311. As Figure 8 shown in the figure, a first limiting post 113 is provided on the first support frame 11 or the second support frame 12.

[0098] Refer to Figure 7, the first support frame 11 or the second support frame 12 is connected to the positioning hole 3115 through the first limiting post 113 penetrating the arc-shaped limiting hole 213 to fixedly connect the gear body 311. The first limiting post 113 can rotate following the gear body 311. The arc-shaped limiting hole 213 is exactly the path for the first limiting post 113 to move. Both ends of the arc-shaped limiting hole 213 limit the rotation range of the first support frame 11 or the second support frame 12 by blocking the first limiting post 113.

[0099] As Figure 4 shown, considering the limited size of the gear, the arc-shaped limiting hole 213 can be communicated with the mounting hole 212, and the arc length of the arc-shaped limiting hole 213 defines the movable range of the gear.

[0100] In one embodiment, the arc-shaped strip 214 and the first limiting post 113 are used for joint limiting. The arc-shaped strip 214 can effectively limit the movement of the gear, and the first limiting post 113 can limit the movement of the support frame, so that the gear and the support frame are limited simultaneously, improving the structural strength of the support and avoiding damage to the support due to excessive force during rotation.

[0101] Embodiment 3

[0102] This embodiment provides an electronic device support. Based on the above embodiment, the movement structures of the third support frame 13 and the fourth support frame 14 are improved. In this embodiment, the first support frame 11 and the second support frame 12 can rotate synchronously, while the third support frame 13 and the fourth support frame 14 rotate independently.

[0103] As Figure 10 and Figure 11 shown, shaft holes 131 are respectively provided on the third support frame 13 and the fourth support frame 14, and two connecting shafts 221 are provided on the second connecting frame 22. The third support frame 13 and the fourth support frame 14 are rotationally connected to the second connecting frame 22 by sleeving the shaft holes 131 correspondingly on the connecting shafts 221.

[0104] Furthermore, arc-shaped limiting grooves 132 are respectively provided on the third support frame 13 and the fourth support frame 14, and a second limiting post 222 is provided on the second connecting frame 22. After the third support frame 13 and the fourth support frame 14 are connected to the second connecting frame 22, the second limiting post 222 is correspondingly located in the arc-shaped limiting grooves 132. The second limiting post 222 rotates following the third support frame 13 and the fourth support frame 14 and is blocked when reaching the end edge of the arc-shaped limiting grooves 132, thereby limiting the rotation range of the third support frame 13 and the fourth support frame 14.

[0105] As Figure 12 and Figure 13As shown (the arrows in the figure indicate the rotation direction), in this embodiment, the third support frame 13 and the fourth support frame 14 are respectively rotatably connected to the second connecting frame 22. The third support frame 13 and the fourth support frame 14 can be rotated to a relatively open state or a relatively folded state. In the relatively open state, the third support frame 13 and the fourth support frame 14 respectively form an angle with the second connecting frame 22. In the relatively folded state, the third support frame 13 and the fourth support frame 14 are close to the second connecting frame 22. The arc length of the arc-shaped limiting groove 132 is the rotation range of the third support frame 13 and the fourth support frame 14. For the design of the arc length of the arc-shaped limiting groove 132, it is only necessary to make its length satisfy the condition that when the second limiting post 222 contacts the end edge of the arc-shaped limiting groove 132, the third support frame 13 and the fourth support frame 14 are exactly in the relatively open state or the relatively folded state. The description of the third support frame 13 and the fourth support frame 14 rotating to the limiting state is the same as that of the first support frame 11 and the second support frame 12 in the above embodiment, and will not be elaborated here.

[0106] Further, as Figure 11 shown, the third support frame 13 and the fourth support frame 14 are respectively provided with silica gel pads 133. The silica gel pads 133 protrude from the surfaces of the third support frame 13 and the fourth support frame 14. The silica gel pads 133 can play a role in buffering and as foot pads when the third support frame 13 and the fourth support frame 14 contact the tabletop. At the same time, the silica gel pads 133 can abut against the second connecting frame 22 when the third support frame 13 and the fourth support frame 14 are close to the second connecting frame 22, which can prevent the third support frame 13 and the fourth support frame 14 from colliding with the second connecting frame 22. Based on such a design, the silica gel pads 133 also play a role in limiting the folding of the third support frame 13 and the fourth support frame 14. When the silica gel pads 133 contact the second connecting frame 22, the folding of the third support frame 13 and the fourth support frame 14 is completed.

[0107] As Figure 1 and Figure 11 shown, the third support frame 13 and the fourth support frame 14 are respectively provided with support legs 134. The support legs 134 are respectively rotatably connected to the third support frame 13 and the fourth support frame 14 through a damping structure. The support legs 134 can be rotated to the back sides of the third support frame 13 and the fourth support frame 14 relative to the silica gel pads 133. In this way, the support legs 134 can serve as the bottom supports of the inclined state brackets, and the laptop can be placed on the support legs 134 to prevent the laptop from falling.

[0108] The support legs 134 are rotatably connected to the third support frame 13 and the fourth support frame 14 through a damping structure, so that the rotation of the support legs 134 has a certain resistance, and this resistance is greater than the gravity of the laptop, which can prevent the gravity of the laptop from being too large to push the support legs 134 to rotate and prevent the laptop from falling.

[0109] In one embodiment, the support leg 134 can also be directly connected to the third support frame 13 and the fourth support frame 14 without using a damping structure, so as to simplify the bracket and reduce the cost. In one embodiment, the support leg 134 is integrally formed with the third support frame 13 and the fourth support frame 14 at an angle. Of course, it can also be detachably connected in a plug-in manner. Therefore, the connection method of the support leg 134 is not limited to one.

[0110] Embodiment 4

[0111] This embodiment provides an electronic device bracket, which further improves the movable structure of the third support frame 13 and the fourth support frame 14 on the basis of the above-mentioned Embodiment 1. In this embodiment, the third support frame 13 and the fourth support frame 14 adopt the same solution as the first support frame 11 and the second support frame 12, and the third support frame 13 and the fourth support frame 14 also rotate synchronously.

[0112] In this embodiment, a gear groove 211 is also opened at the end of the second connecting frame 22. The third support frame 13 and the fourth support frame 14 are connected by a second gear assembly. The structure and connection relationship of the second gear assembly are similar to those of the first gear assembly in the above-mentioned embodiment. The third support frame 13 and the fourth support frame 14 can be synchronously moved to a relatively open state or a relatively folded state through the second gear assembly. The connection solution of the third support frame 13 and the fourth support frame 14 through the second gear assembly is the same as that in the above-mentioned embodiment, and will not be elaborated in this embodiment.

[0113] The first support frame 11 and the second support frame 12 of the electronic device bracket in this embodiment can rotate synchronously, and the third support frame 13 and the fourth support frame 14 can also rotate synchronously. When opening or closing the bracket, only the first support frame 11 or the second support frame 12 needs to be rotated, and then the third support frame 13 and the fourth support frame 14 are rotated. The opening or closing of the bracket can be completed only through two simple rotation steps, which greatly improves the convenience of the bracket folding operation.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
