An external helical gear is fitted tightly onto the shaft portion of the gear shaft. The system end bracket is equipped with support feet that slide vertically. The support feet have an internal helical gear structure, and the external helical gear meshes with the support feet.

[0010] A connecting bracket assembly is installed between the screen-side axis and the system-side axis. The screen-side axis and the system-side axis are rotatably connected to the connecting bracket assembly. The connecting bracket assembly is provided with a first driving slope and a second driving slope. The first driving slope and the second driving slope are located on both sides of the sliding component assembly of the movable sliding component. The sliding component assembly is provided with a first contact slope corresponding to the first driving slope and a second contact slope corresponding to the second driving slope.

[0011] During the 360-degree rotation of the computer screen relative to the computer system, the hinge assembly of the laptop lifting foot pad has a foot pad extension and rotation state and a foot pad retraction and rotation state. In the foot pad extension and rotation state, the first driving inclined surface pushes against the first contact inclined surface and causes the movable sliding member to slide forward relative to the system end bracket, and the supporting foot pad gradually extends downward. In the foot pad retraction and rotation state, the second driving inclined surface pushes against the second contact inclined surface and causes the movable sliding member to slide in the opposite direction relative to the system end bracket, and the supporting foot pad gradually retracts downward.

[0018] During the 360-degree rotation of the computer screen relative to the computer system, the hinge assembly of the laptop lift pad has three states: a foot pad extended and rotating, a foot pad held in rotation, and a foot pad retracted and rotating. When the hinge assembly is in the extended and rotating state, the system-side protrusion slides within the first straight groove of the straight groove post, one end of the moving wheel extends into the first groove of the screen-side switching wheel, and the other end of the moving wheel abuts against the circumferential surface of the system-side switching wheel. When the hinge assembly is in the extended and rotating state... While the foot pad is in a rotating state, one end of the moving wheel extends into the groove of the switching wheel on the system side, and the other end of the moving wheel abuts against the circumferential surface of the switching wheel on the screen side. The system side protrusion of the track post moves from the first straight groove of the straight groove post to the second straight groove. When the hinge assembly of the lifting laptop foot pad is in the foot pad retracted rotation state, the system side protrusion moves in the second straight groove of the straight groove post, one end of the moving wheel extends into the second groove of the switching wheel on the screen side, and the other end of the moving wheel abuts against the circumferential surface of the switching wheel on the system side.

[0019] The movable sliding member has a sliding member groove that opens toward the side of the system end bracket, and the edge of the system end bracket extends into the sliding member groove of the movable sliding member.

[0020] The system end bracket is provided with two bracket protrusions that extend downwards respectively. The two bracket protrusions are located on the two sides directly opposite the support foot pad. Each bracket protrusion is provided with a guide flange that protrudes towards the support foot pad and extends vertically.

Detailed Implementation

[0037] The present invention will now be described in conjunction with specific embodiments.

[0038] Example 1, as Figure 1 As shown, a hinge assembly for raising a laptop computer foot pad is provided. The laptop computer includes a computer screen end 1 and a computer system end 2. The rear end of the computer screen end 1 is connected to the rear end of the computer system end 2 through the hinge assembly.

[0039] Among them, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10 As shown, the hinge assembly includes a screen end bracket 31 fastened to the computer screen end 1, a system end bracket 41 fastened to the computer system end 2, a screen end side axis 32 fastened to the screen end bracket 31, and a system end side axis 42 fastened to the system end bracket 41. The screen end side axis 32 and the system end side axis 42 are arranged parallel to each other at intervals.

[0040] Furthermore, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 11 as well as Figure 12 As shown, the system end bracket 41 is equipped with a movable sliding member 51 that slides along the axis of the system end side shaft 42. The movable sliding member 51 includes a shaft sleeve part 511 and a drive rack 512 disposed on the shaft sleeve part 511. The shaft sleeve part 511 is rotatably fitted around the system end side shaft 42. The system end bracket 41 is equipped with a gear shaft 53 through a bearing 52. The gear part of the gear shaft 53 meshes with the drive rack 512. The shaft part of the gear shaft 53 is fitted with an external helical gear 54. The system end bracket 41 is equipped with a support foot pad 55 that slides vertically. The support foot pad 55 has an internal helical gear structure, and the external helical gear 54 meshes with the support foot pad 55.

[0041] Furthermore, such as Figure 2 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9As shown, a connecting bracket assembly 6 is installed between the screen-side axis 32 and the system-side axis 42. The screen-side axis 32 and the system-side axis 42 are rotatably connected to the connecting bracket assembly 6. The connecting bracket assembly 6 is provided with a first driving inclined surface 61 and a second driving inclined surface 62. The first driving inclined surface 61 and the second driving inclined surface 62 are located on both sides of the sliding component assembly of the movable sliding component 51. The sliding component assembly is provided with a first contact inclined surface 5111 corresponding to the first driving inclined surface 61 and a second contact inclined surface 5112 corresponding to the second driving inclined surface 62.

[0042] In addition, during the process of the computer screen end 1 rotating 360 degrees relative to the computer system end 2, the hinge assembly of the lifting laptop foot pad has a foot pad extended rotation state and a foot pad retracted rotation state; in the foot pad extended rotation state, the first driving inclined surface 61 pushes the first contact inclined surface 5111 and causes the movable sliding member 51 to slide forward relative to the system end bracket 41, and the supporting foot pad 55 gradually extends downward; in the foot pad retracted rotation state, the second driving inclined surface 62 pushes the second contact inclined surface 5112 and causes the movable sliding member 51 to slide in the opposite direction relative to the system end bracket 41, and the supporting foot pad 55 gradually retracts downward.

[0043] It should be explained that, for the assembly consisting of the movable sliding member 51, bearing 52, gear shaft 53, external helical gear 54, and support foot pad 55, during operation, as the movable sliding member 51 is pushed forward or backward relative to the system end bracket 41 by the first driving inclined surface 61 or the second driving inclined surface 62, the driving rack 512 of the movable sliding member 51 drives the gear part of the gear shaft 53 to rotate, thereby causing the entire gear shaft 53 to rotate. The rotating gear shaft 53 drives the external helical gear 54 to rotate. Since the support foot pad 55 is an internal helical gear structure and this internal helical gear structure meshes with the external helical gear 54, that is, the rotating external helical gear 54 drives the support foot pad 55 to perform lifting and lowering actions relative to the system end bracket 41, thereby realizing the automatic lifting and lowering of the foot pad.

[0044] In summary, the hinge assembly of the laptop computer foot pad in this embodiment has the advantages of novel structural design and convenient use, and can automatically raise and lower the support foot pad 55 when the computer screen end 1 is flipped, thereby effectively improving the ease of use of the laptop computer.

[0045] Example 2, as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 as well as Figure 10As shown, the difference between this embodiment 2 and embodiment 1 is that the connecting bracket group 6 includes a first bracket 63, a second bracket 64, and a third bracket 65 arranged in sequence. One end of the first bracket 63, the second bracket 64, and the third bracket 65 are respectively rotatably fitted onto the screen end side axis 32, and the other end of the first bracket 63, the second bracket 64, and the third bracket 65 are respectively rotatably fitted onto the system end side axis 42.

[0046] The first driving inclined surface 61 is disposed on the first bracket 63.

[0047] In addition, the connecting bracket assembly 6 also includes a sleeve 66 that is rotatably fitted around the periphery of the system end side shaft 42. The sleeve 66 is inserted into the first bracket 63 and is anti-rotationally connected. The second driving inclined surface 62 is disposed on the sleeve 66. The sliding part of the movable sliding member 51 is rotatably fitted around the periphery of the sleeve 66.

[0048] Furthermore, the second bracket 64 is slidably mounted with a track post 71 that slides along the axial direction of the screen-side axis 32 and the system-side axis 42. The track post 71 is located between the screen-side axis 32 and the system-side axis 42. The track post 71 is provided with a screen-side protrusion 711 protruding towards the screen-side axis 32 and a system-side protrusion 712 protruding towards the system-side axis 42. The screen-side axis 32 is fitted between the first bracket 63 and the second bracket 64 and moves accordingly. The inclined groove column 72 rotates synchronously with the screen end side axis 32. The system end side axis 42 is fitted with a straight groove column 73 located between the first bracket 63 and the second bracket 64 and rotates synchronously with the system end side axis 42. The outer circumferential surface of the inclined groove column 72 is provided with a spiral inclined groove 721 extending spirally. The outer circumferential surface of the straight groove column 73 is provided with a first straight groove 731 and a second straight groove 732 that are interconnected and extend circumferentially. The screen end side protrusion 711 extends into the spiral inclined groove 721 of the inclined groove column 72.

[0049] In addition, a screen-side switching wheel 81 is also fitted on the screen-side axis 32, which is located between the second bracket 64 and the third bracket 65 and rotates synchronously with the screen-side axis 32. The system-side axis 42 is fitted with a system-side switching wheel 82, which is located between the second bracket 64 and the third bracket 65 and rotates synchronously with the system-side axis 42. The circumferential surface of the screen-side switching wheel 81 is provided with a first groove 811 and a second groove 812 arranged circumferentially. The circumferential surface of the system-side switching wheel 82 is provided with a switching wheel groove 821. The third bracket 65 is slidably mounted with a moving wheel 83 that slides radially along the screen-side axis 32 and the system-side axis 42. The moving wheel 83 is located between the screen-side switching wheel 81 and the system-side switching wheel 82.

[0050] It should be noted that during the 360-degree rotation of the computer screen end 1 relative to the computer system end 2, the hinge assembly of the laptop lifting foot pad has three states: foot pad extended and rotating, foot pad held and rotating, and foot pad retracted and rotating. When the hinge assembly of the laptop lifting foot pad is in the foot pad extended and rotating state, the system end side protrusion 712 slides in the first straight groove 731 of the straight groove post 73, one end of the moving wheel 83 extends into the first groove 811 of the screen end side switching wheel 81, and the other end of the moving wheel 83 abuts against the circumferential surface of the system end side switching wheel 82. When the hinge assembly of the laptop lifting foot pad is in the foot pad held and rotating state... In the first position, one end of the moving wheel 83 extends into the switching wheel groove 821 of the system-side switching wheel 82, and the other end of the moving wheel 83 abuts against the circumferential surface of the screen-side switching wheel 81. The system-side protrusion 712 of the track post 71 switches from the first straight groove 731 of the straight groove post 73 to the second straight groove 732. When the hinge assembly of the lifting laptop foot pad is in the foot pad retracted rotation state, the system-side protrusion 712 moves in the second straight groove 732 of the straight groove post 73, one end of the moving wheel 83 extends into the second groove 812 of the screen-side switching wheel 81, and the other end of the moving wheel 83 abuts against the circumferential surface of the system-side switching wheel 82.

[0051] The following is a detailed description of the hinge assembly for lifting the laptop feet in Embodiment 2, using specific action procedures as an example:

[0052] Step 1: Flip the computer screen end 1 relative to the computer system end 2, causing the hinge assembly of the laptop lifting foot pad to enter the foot pad extension and rotation state. During this process, the system end side protrusion 712 slides in the first straight groove 731 of the straight groove post 73, one end of the moving wheel 83 extends into the first groove 811 of the screen end side switching wheel 81, and the other end of the moving wheel 83 abuts against the circumferential surface of the system end side switching wheel 82. At this time, because the moving wheel 83 locks the screen end side switching wheel 81, the screen end side axis 32 cannot be connected to the bracket assembly 6. The system rotates, and the connecting bracket group 6 can rotate relative to the system end side axis 42. During this process, the first driving inclined surface 61 of the first bracket 63 contacts and abuts the first contact inclined surface 5111 of the movable sliding member 51, causing the movable sliding member 51 to slide forward relative to the system end bracket 41. The movable sliding member 51, which slides forward relative to the system end bracket 41, drives the gear shaft 53 to rotate through the driving rack 512, thereby causing the support foot pad 55 to gradually extend downward relative to the system end bracket 41, so as to make the support foot pad 55 raise the computer system end 2 too high.

[0053] When the foot pad is extended and rotated into position, the system end side protrusion 712 of the track column 71 slides to the end position of the first straight groove 731. Due to the limiting effect of the track column 71, the connecting bracket group 6 cannot continue to rotate relative to the system end side axis 42.

[0054] Step 2: When the foot pad extends and reaches the rotated position, the switching wheel of the system-side switching wheel 82 is aligned with the moving wheel 83. At this time, the end of the moving wheel 83 enters the switching wheel groove 821 of the system-side switching wheel 82, and the moving wheel 83 exits the first groove 811 of the screen-side switching wheel 81. At this time, the limiting effect of the moving wheel 83 on the screen-side switching wheel 81 disappears, and the screen-side axis 32 can rotate relative to the connecting bracket assembly 6, i.e., it enters the foot pad and maintains the rotating state. During this process, one end of the moving wheel 83 extends into the system end... Inside the switching wheel groove 821 of the side switching wheel 82, the other end of the moving wheel 83 abuts against the circumferential surface of the screen-side switching wheel 81. Under the driving action of the spiral inclined groove 721 of the screen-side switching wheel 81 on the track column 71, the track column 71 moves relative to the second bracket 64 and the system end side protrusion 712 of the track column 71 slides from the end of the first straight groove 731 of the straight groove column 73 into the second straight groove 732. That is, the system end side protrusion 712 of the track column 71 switches from the first straight groove 731 of the straight groove column 73 to the second straight groove 732.

[0055] When the foot pad is in a rotating state, neither the first driving ramp 61 nor the second driving ramp 62 will act on the corresponding first contact ramp 5111 and second contact ramp 5112 of the movable sliding member 51, and the supporting foot pad 55 is maintained at the maximum support height.

[0056] Furthermore, when the foot pad is in the rotating state, the screen end protrusion 711 of the track column 71 reaches the end of the spiral groove 721 of the inclined groove column 72, and the second groove 812 of the screen end switching wheel 81 is aligned with the end of the moving wheel 83. At this time, the track column 71 limits the inclined groove column 72.

[0057] Step 3: After the foot pad is in the rotating position, it enters the foot pad retraction and rotation state. At this time, the system end side protrusion 712 moves in the second straight groove 732 of the straight groove post 73. One end of the moving wheel 83 extends into the second groove 812 of the screen end side switching wheel 81, and the other end of the moving wheel 83 abuts against the circumferential surface of the system end side switching wheel 82. During this process, the second driving inclined surface 62 of the sleeve 66 contacts and abuts against the second contact inclined surface 5112 of the movable sliding member 51, causing the movable sliding member 51 to slide in the opposite direction relative to the system end bracket 41. The movable sliding member 51 sliding in the opposite direction relative to the system end bracket 41 drives the gear shaft 53 to rotate through the driving rack 512, thereby causing the support foot pad 55 to gradually retract upward relative to the system end bracket 41, so as to realize the retraction of the support foot pad 55, so as to ensure that the support foot pad 55 will not interfere with the casing of the computer screen end 1 when the computer screen end 1 is rotated 360 degrees relative to the computer system end 2.

[0058] Example 3, as Figure 10As shown, the difference between this embodiment 3 and embodiment 1 is that the movable sliding member 51 has a sliding member groove 513 that opens toward the system end bracket 41, and the edge of the system end bracket 41 extends into the sliding member groove 513 of the movable sliding member 51.

[0059] By having the sliding groove 513 of the sliding member cooperate with the edge of the system end bracket 41, this embodiment 3 can ensure that the movable sliding member 51 can slide smoothly in the forward and reverse directions relative to the system end bracket 41.

[0060] Example 4, as Figure 5 and Figure 12 As shown, the difference between this embodiment 4 and embodiment 1 is that: the system end bracket 41 is provided with two bracket protrusions 411 that extend downwards respectively. The two bracket protrusions 411 are located on the two sides directly opposite the support foot pad 55. Each bracket protrusion 411 is provided with a guide flange 4111 that protrudes towards the support foot pad 55 and extends vertically respectively; the outer side wall of the support foot pad 55 is provided with a guide groove 551 corresponding to each guide flange 4111.

[0061] By cooperating with the guide flange 4111 and the guide groove 551, this embodiment four can effectively ensure that the support foot pad 55 can perform lifting and lowering actions.

[0062] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
