[0033] The utility model provides a notebook computer stand.

[0034] In the embodiment of the present utility model, Figures 1 to 6 As shown, the laptop computer stand includes a bottom plate 10 , a placement plate 20 and a support frame 30 .

[0035] The bottom plate 10 is provided with a first limiting structure 11 .

[0036] The placing plate 20 and the bottom plate 10 are stacked, and a second limiting structure 23 is provided on the side of the placing plate 20 facing the first limiting structure 11. The placing plate 20 has a first position and a second position. In the first position, the placing plate 20 is tilted relative to the bottom plate 10. In the second position, the placing plate 20 is parallel to the bottom plate 10, and the placing plate 20 is located above the bottom plate 10.

[0037] The support frame 30 includes a mounting bracket 31, a first supporting plate 32 and a second supporting plate 33. The mounting bracket 31 is arranged between the base plate 10 and the placement plate 20. One end of the mounting bracket 31 is rotatably connected to the base plate 10, and the other end is rotatably connected to the placement plate 20. The mounting bracket 31 has an installation space. The first supporting plate 32 and the second supporting plate 33 are both rotatably installed on the side wall of the installation space. The rotation axes of the first supporting plate 32 and the second supporting plate 33 are parallel to the rotation axis of the mounting bracket 31. The first supporting plate 32 and the second supporting plate 33 both have a storage state and an abutment state. In the storage state, the first supporting plate 32 and the second supporting plate 33 are both located in the installation space. In the abutment state, the first supporting plate 32 abuts and cooperates with the first limiting structure 11, and the second supporting plate 33 limits and cooperates with the second limiting structure 23 to limit the placement plate 20 to the second position; the first supporting plate 32 cooperates with the first limiting structure 11 to limit the placement plate 20 to the first position.

[0038] The base plate 10 has a first side and a second side opposite to each other, and the placement plate 20 has a first side and a second side opposite to the first side and the second side of the base plate 10, that is, the first side of the placement plate 20 is arranged opposite to the first side of the base plate 10, and the second side of the placement plate 20 is arranged opposite to the second side of the base plate 10, one end of the mounting bracket 30 is hinged to the first side of the base plate 10, and the other end of the mounting bracket 30 is hinged to the second side of the placement plate 20.

[0039] In this embodiment, when in the first position, the first support plate 32 is in abutment with the first limiting structure 11 on the bottom plate 10, and the first support plate 32 supports the mounting bracket 31, which is equivalent to supporting the placement plate 20 to which the mounting bracket 31 is rotatably connected, so as to limit the placement plate 20 to a state of being tilted relative to the bottom plate 10, so that when the laptop is placed on the placement plate 20, the angle of the laptop display screen can be adjusted to improve the viewing effect of the user. Optionally, the placement plate 20 is provided with a limiting structure to prevent the computer from sliding off the placement plate 20 when it is placed on the inclined surface of the placement plate 20. Specifically, the limiting structure can be an abutment block provided on the lower side of the placement plate 20 (the side close to the bottom plate 10 when in the tilted state), so as to abut the computer through the abutment block to prevent it from sliding off.

[0040] In the second position, the first support plate 32 abuts against the first limiting structure 11 on the bottom plate 10, and the second support plate 33 abuts against the second limiting structure 23. The first support plate 32 supports the mounting bracket 31 to prevent the mounting bracket 31 from moving toward the bottom plate 10 under the action of gravity. The second support plate 33 supports the placement plate 20 to prop up the inclined placement plate 20, that is, under the cooperation of the first support plate 32 and the second support plate 33, the placement plate 20 is limited to a state parallel to the bottom plate 10. This is equivalent to raising the placement plate 20, so that when the user places the laptop on the board surface of the placement plate 20, the laptop can be on a higher plane. In this way, when the user is tired from sitting for a long time and wants to operate the computer while standing, the placement plate 20 can be adjusted to the second position to raise the placement position of the laptop, so that there is no need to lift the laptop or bend over to operate the computer, so as to meet the different usage needs of users and help improve the user experience.

[0041] In the storage state, the first support plate 32 and the second support plate 33 can be stored in the installation space, which is equivalent to using the space of the installation bracket 31 to store the first support plate 32 and the second support plate 33, which is beneficial to reduce the occupied space and improve the structural compactness of the laptop computer bracket.

[0042] The technical solution of the utility model is to set a first limiting structure 11 on the bottom plate 10, stack the placement plate 20 and the bottom plate 10, and set a second limiting structure 23 on the side of the placement plate 20 facing the bottom plate 10. The placement plate 20 has a first position and a second position. In the first position, the placement plate 20 is inclined relative to the bottom plate 10. In the second position, the placement plate 20 and the bottom plate 10 are parallel to each other, and the placement plate 20 is located above the bottom plate 10. The mounting bracket 31 is rotatably installed between the bottom plate 10 and the placement plate 20, and The first support plate 32 and the second support plate 33 are both arranged in the installation space of the installation bracket 31, and are both rotatably connected to the installation bracket 31. The first support plate 32 and the second support plate 33 both have a storage state and an abutment state. In the abutment state, the first support plate 32 abuts and cooperates with the first limiting structure 11, and the second support plate 33 limits and cooperates with the second limiting structure 23 to limit the placement plate 20 to the second position; the first support plate 32 cooperates with the first limiting structure 11 to limit the placement plate 20 to the first position. In this way, when the user is sitting and using a laptop computer, the placement plate 20 can be limited to the first position by the first support plate 32 to tilt the placement plate 20. When the user is tired after sitting for a long time, the first support plate 32 can be abutted and cooperated with the first limiting structure 11, and the second support plate 33 can be abutted and cooperated with the second limiting structure 23 to limit the placement plate 20 to the second position, so that the placement plate 20 and the base plate 10 are parallel to each other. In this way, the user can adjust the placement plate 20 to the first position when sitting, and can adjust the placement plate 20 to the second position when standing, so as to meet the different usage needs of the user.

[0043] In some embodiments, the first limiting structure 11 includes a plurality of first limiting strips 111, which are arranged at intervals in a direction perpendicular to the axis of the mounting frame, and a limiting groove 113 is formed between two adjacent first limiting strips 111, and the first support plate 32 is plugged into one of the limiting grooves 113.

[0044] Specifically, there are at least three first limiting strips 111, that is, two limiting grooves 113 are formed between the three first limiting strips 111, and multiple first limiting strips 111 form multiple limiting grooves 113 on the bottom plate 10. When the first support plate 32 is plugged into the limiting groove 113 near the connection position of the mounting bracket 31 and the bottom plate 10, the placement plate 20 is at the maximum inclination angle. When the first support plate 32 is plugged into the limiting groove 113 away from the connection position of the mounting bracket 31 and the bottom plate 10, the inclination angle of the placement plate 20 is reduced. In this way, the user can adjust according to the use requirements during actual use, which is conducive to improving the user experience. Exemplarily, the number of first limiting strips 111 can be three, four, five, etc. Of course, the design of the present application is not limited to this. In other embodiments, multiple plug-in slots are dug on the bottom plate 10, and the multiple plug-in slots are spaced apart in a direction perpendicular to the mounting bracket 31, and the first support plate 32 selects a plug-in hole for plugging.

[0045] Furthermore, the second limiting structure 23 includes a plurality of second limiting bars, which are arranged at intervals in a direction perpendicular to the axis of the mounting frame, and a second limiting groove 113 is formed between two adjacent second limiting bars, and the second support plate 33 is plugged into one of the second limiting grooves 113 .

[0046] Specifically, there are at least three second limit bars, and two limit grooves 113 are formed between the three second limit bars. Multiple second limit bars form multiple limit grooves 113 on the placement plate 20. When the second support plate 33 is inserted into the limit groove 113 near the connection position between the mounting bracket 31 and the placement plate 20, the placement plate 20 is in the highest position. When the second support plate 33 is inserted into the limit groove 113 away from the connection position between the mounting bracket 31 and the placement plate 20, the distance between the placement plate 20 and the bottom plate 10 is the smallest, and the placement plate 20 is in the lowest position. In this way, the user can adjust according to the use requirements during actual use, which is conducive to improving the user experience. Exemplarily, the number of second limit bars can be three, four, five, and so on.

[0047] In some embodiments, the first limiting structure 11 further includes a mounting plate 112 , which is detachably mounted on the bottom plate 10 , and a plurality of first limiting strips 111 are mounted on the mounting plate 112 .

[0048] Specifically, during the assembly process, the plurality of first limiting strips 111 can be first installed on the mounting plate 112, and then the mounting plate 112 can be installed on the bottom plate 10. This arrangement is conducive to reducing the difficulty of assembly and the production cost. Of course, in other implementations, the plurality of first limiting strips 111 can also be directly installed on the bottom plate 10.

[0049] In some embodiments, the first support plate 32 is provided with avoidance holes 324 at positions corresponding to multiple first limit strips 111, and the placement plate 20 also has a third position. In the third position, the base plate 10, the support frame 30 and the placement plate 20 are stacked in sequence from bottom to top. In the third position, at least part of the first limit strips 111 are located in the avoidance holes 324.

[0050] Specifically, the third position of the placement plate 20 is the storage state of the laptop computer stand, and a avoidance hole 324 is set on the first support plate 32 corresponding to the first limit strip 111, so that when stored, the first limit strip 111 can be extended into the avoidance hole 324, which is equivalent to using the space of the first abutment plate to accommodate the first limit strip 111. Such a setting is conducive to reducing the occupied space of the laptop computer stand and improving the structural compactness of the laptop computer stand. Among them, at least part of at least one first limit strip 111 extends into the avoidance hole 324, and the other first limit strips 111 located outside the range of the first abutment plate are located on the outside of the first abutment plate, or in other words, all of the multiple first limit strips 111 extend into the avoidance hole 324. Of course, in other embodiments, the first abutment plate may not be provided with the avoidance hole 324.

[0051] In some embodiments, the first support plate 32 includes a plate body 321, an annular frame 322 and a plurality of reinforcing ribs 323. The plate body 321 is rotatably mounted on the inner wall of the mounting bracket 31. The annular frame 322 is in the shape of a connecting ring extending along the periphery of the plate body 321. The plurality of reinforcing ribs 323 are located on the inner side of the annular frame 322. The plurality of reinforcing ribs 323 are connected to the surface of the plate body 321 and the annular frame 322. The plurality of reinforcing ribs 323 are criss-crossedly arranged.

[0052] Specifically, the annular frame 322 is connected to the periphery of the plate body 321 , and the plurality of reinforcing ribs 323 can effectively improve the structural strength of the first support plate 32 , which is beneficial to improving the supporting force of the first support plate 32 .

[0053] Furthermore, the plate body 321, the annular frame 322 and the plurality of reinforcing ribs 323 are integrally formed. As we know, the integral forming process has high production efficiency, high structural strength, and helps to reduce production costs. Of course, the design of the present application is not limited thereto. In other embodiments, the plate body 321, the annular frame 322 and the plurality of reinforcing ribs 323 can be connected to each other by means of clamping, fastening with fasteners, etc.

[0054] It is worth noting that the structure of the second support plate 33 is the same as that of the first support plate 32 , so the structure of the second support plate 33 will not be described in detail, and the details may refer to the above description of the structure of the first support plate 32 .

[0055] In some embodiments, the first support plate 32 and the second support plate 33 are both made of plastic material. It is understood that the structure made of plastic material can ensure structural strength while saving production costs. Of course, in other embodiments, the first support plate 32 and the second support plate 33 are made of metal material.

[0056] In some embodiments, the mounting bracket 31 includes two connecting plates, both of which are arranged between the base plate 10 and the placement plate 20. The two connecting plates are arranged opposite to each other, and the two connecting plates are spaced to form an installation space. The first support plate 32 and the second support plate 33 are both rotatably installed between the two connecting plates.

[0057] Specifically, one end of the two connecting plates is rotatably connected to the bottom plate 10, and the other end is rotatably connected to the placement plate 20. The two connecting plates are spaced apart from each other to form an installation space, that is, the first support plate 32 and the second support plate 33 are rotatably installed between the two connecting plates. In other words, the first support plate 32 and the second support plate 33 are rotatably installed at both ends of the two connecting plates. Such a configuration can facilitate the assembly of the support frame 30, and the structure is simple, which is conducive to reducing production costs.

[0058] In some embodiments, the placement plate 20 is provided with a plurality of heat dissipation holes 24, and the plurality of heat dissipation holes 24 all penetrate the placement plate 20. Specifically, there are at least two heat dissipation holes 24. When the laptop is in use, a large amount of heat is generated. By providing the heat dissipation holes 24 on the placement plate 20, when the laptop is placed on the placement plate 20, the heat generated by the laptop can be discharged from the heat dissipation holes 24, thereby improving the heat dissipation efficiency of the laptop. Exemplarily, the number of heat dissipation holes 24 can be, but not limited to, two, three, four, and the like. Of course, in other embodiments, the number of heat dissipation holes 24 can also be one, and one heat dissipation hole 24 is in the shape of a ring extending along the circumference of the placement plate 20.

[0059] Optionally, a heat dissipation fan is disposed on the lower surface of the placement plate 20, and the heat dissipation fan is disposed at the position of the heat dissipation hole 24, so that the heat dissipation fan drives the air flow to blow quickly toward the laptop computer; or the heat dissipation fan drives the hot air flow in the laptop computer to be quickly discharged.

[0060] In some embodiments, a plurality of anti-skid pads are provided on one side of the bottom plate 10 away from the first limiting structure 11, and the plurality of anti-skid pads are spaced apart along the circumference of the bottom plate 10. Specifically, the number of the anti-skid pads is at least two, and when the bottom plate 10 is placed on the desktop, the anti-skid pads can increase the friction between the bottom plate 10 and the desktop to prevent it from sliding. Exemplarily, the number of the anti-skid pads can be but not limited to two, three, four, etc. Of course, in other embodiments, the number of the anti-skid pad can also be one, and the anti-skid pad is in the shape of a ring extending along the circumference of the bottom plate 10.

[0061] In some embodiments, the bottom plate 10 is provided with a first fastening member 12 at a position corresponding to the hinged connection between the mounting bracket 31 and the placement plate 20. When in the third position, the first fastening member 12 is fastened to the hinged connection between the mounting bracket 31 and the placement plate 20. In this way, when the laptop stand is stored, the first fastening member 12 is fastened to the hinge, which can prevent the mounting bracket 31 and the placement plate 20 from rotating, so as to fix the position of the placement plate 20 and keep it in the stored state, which is conducive to improving the user experience.

[0062] Furthermore, the placement plate 20 is provided with a second fastening member 25 at the position where the mounting bracket 31 is electrically hinged. When in the third position, the second fastening member 25 is fastened to the rotating shaft hinged to the bottom plate 10. In this way, when the laptop stand is stored, the second fastening member 25 is engaged with the rotating shaft, which can prevent the mounting bracket 31 and the bottom plate 10 from rotating. That is, the cooperation between the second fastening member 25 and the first fastening member 12 can prevent the bottom plate 10 and the placement plate 20 from rotating, which is conducive to further improving the user experience.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
