Abstract
Description
Technical Field
[0001] This disclosure relates to the field of foot height adjustment technology for electronic devices, and more particularly to a lifting structure and electronic device for adjusting the height of foot pads. Background Technology
[0002] Modern laptop designs increasingly favor lightweight and thin designs, making overall height a crucial factor. Therefore, to reduce overall height, the height of the feet is often sacrificed, leading to other problems. For example, when a laptop is opened to a certain angle, the bottom edge of the display collides with the desktop, causing motion interference. Over time, this can result in paint chipping and discoloration on the bottom edge of the display. Current solutions involve developing more wear-resistant coatings or other surface treatments to mitigate friction marks caused by the display's contact with the desktop. However, this approach increases the complexity and requirements of the surface treatment process and does not fundamentally address the impact issue itself. Utility Model Content

[0015] In one possible implementation, the transmission link is constructed as a single piece;
[0016] Alternatively, the transmission link can be constructed as two separate segments spaced apart along the first direction. The two separate segments are respectively designated as a first transmission link segment and a second transmission link segment, wherein the first transmission link segment meshes with the gear set for transmission, and the second transmission link segment is linked with the foot pad movement assembly.

[0018] In one embodiment, the first end of the hinge shaft is fixedly connected to the display end and rotates with the display end, and the second end of the hinge shaft is connected to the system end through a second mounting groove;
[0019] The hinge shaft includes a shaft body and a spindle connected to one end of the shaft body. The first end of the shaft body is fixedly connected to the display end.

Compared with the existing solutions, the lifting structure of this application is more suitable for the ultra-thin design of laptops.

Detailed Implementation
[0037] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0038] According to one embodiment of this disclosure, such as Figure 1-6 As shown, this utility model provides a lifting structure 1 (hereinafter referred to as "lifting structure") for adjusting the height of a foot pad, including a linkage mechanism, which is used to drive the foot pad 2 to lift or lower; the linkage mechanism includes:
[0039] Gear set 3, which is used to link with the hinge shaft 4 of the electronic device;
[0040] The transmission link 5 has its first end meshing with the gear set 3, thereby reciprocating linearly along the first direction under the meshing transmission of the gear set;
[0041] The foot pad motion component 6 is linked to the second end of the transmission link 5 and the foot pad 2. The foot pad motion component 6 is configured to reciprocate linearly along the second direction under the drive of the reciprocating linear motion of the transmission link 5, thereby synchronously driving the foot pad 2 to rise or fall.
[0042] In this embodiment, the so-called first direction is Figure 1 The X direction shown is the second direction. Figure 1 The Z direction is shown in the diagram.
[0043] In this embodiment, the electronic device includes, but is not limited to, a laptop computer. Taking a laptop computer as an example, this application employs a linkage mechanism that can drive the feet to rise or fall. The gear set can be linked with the hinge shaft built into the laptop computer. When the laptop computer is opened or closed, the hinge shaft rotates, and the gear set rotates synchronously with the hinge shaft. This causes the transmission linkage meshing with the gear set to reciprocate linearly along a first direction, thereby driving the foot pad movement assembly to reciprocate linearly along a second direction, thus synchronously raising or lowering the feet. Therefore, the lifting structure of this application is simpler and more efficient, requiring fewer parts and fewer types of transmission parts, saving costs while the gear set arrangement saves space. Because the lifting structure of this application requires fewer parts and occupies less space in the overall machine, it does not require a large space on the rear side of the machine for the foot pad retraction structure, resulting in better overall integrity of the laptop computer and maintaining a unified appearance on the D-component when the machine is opened or closed.
[0044] When this lifting structure is applied to electronic devices, especially laptops, it effectively maintains the overall aesthetics of the laptop and solves the problem of motion interference during the opening and closing of the display. The lifting structure allows for adjustment of the feet height, thus adjusting the laptop's tilt angle for greater comfort and a better user experience. Furthermore, it allows for adjustment of the distance between the rear of the laptop's system panel and the desktop, improving bottom heat dissipation.
[0045] In addition, the present application has fewer exposed lifting structures and fewer telescopic structures, which reduces the structural failure rate and improves the reliability of the structure.
[0046] In some embodiments, such as Figure 7-12 As shown, the foot pad motion assembly 6 includes a first mounting groove 61 and a connecting rod pair 62. The first end of the connecting rod pair 62 is linked with the second end of the transmission connecting rod 5 and the first mounting groove 61, and the second end of the connecting rod pair 62 is linked with the foot pad 2.
[0047] In this embodiment, the connecting pair 62 has a simple structure. The first mounting groove 61 provides the basis for the linkage between the connecting pair 62 and the transmission link 5. When the transmission link moves linearly along the first direction, the connecting pair 62 can follow the movement of the transmission link. For example, taking the opening of a laptop as an example, when the hinge of the laptop rotates, it drives the gear set to rotate, causing the transmission link to move linearly towards the foot pad moving assembly 6, pushing the connecting pair, and causing the connecting pair to drive the foot pad 2 to fall. Thus, the foot pad moving assembly 6 of this application can initially realize the lifting or lowering of the foot pad by using the connecting pair and the first mounting groove. The structure is simple and occupies little space.
[0048] Furthermore, for example, the linkage 62 consists of a first link 621 and a second link 622 that are crossed and hinged;
[0049] The first end of the first connecting rod 621 is hinged to the second end of the transmission connecting rod 5, and the hinged position of the two is movably mounted on the first mounting groove 61; the second end of the first connecting rod 621 is hinged to the foot pad 2; the first end of the second connecting rod 622 is hinged to the first mounting groove 61, and the second end of the second connecting rod 622 is movably mounted on the foot pad 2.
[0050] like Figure 8-12 As shown, the first mounting groove 61 is generally a cuboid structure with its opening facing downwards, and a clearance opening 613 is provided on the first mounting groove 61. The second end of the transmission connecting rod 5 is movably inserted into the clearance opening 613, thereby hinged to the connecting rod pair 62.
[0051] Two sets of connecting rod pairs 62 are provided, each with the same structure. Taking one set of connecting rod pairs as an example, a long strip-shaped first mounting hole 611 is provided on the first mounting groove 61. The first end of the first connecting rod 621 and the second end of the transmission connecting rod 5 are respectively provided with first hinge shaft holes 51 at corresponding positions. The hinge shaft (not shown in the figure) is inserted into the first mounting hole 611 and the first hinge shaft hole 51, so that the first end of the first connecting rod 621 can be hinged with the second end of the transmission connecting rod 5, and the transmission connecting rod 5 can drive the first connecting rod 621 to reciprocate along the first mounting hole 611 of the first mounting groove. The second end of the first connecting rod 621 and the foot pad 2 are respectively provided with second hinge shaft holes 21 at corresponding positions, and the hinge shaft is inserted into the second hinge shaft hole 21 to realize the hinged connection between the second end of the first connecting rod 621 and the foot pad 2.
[0052] Similarly, referring to the first connecting rod, the first end of the second connecting rod 622 and the corresponding position of the first mounting groove 61 are respectively provided with third hinge shaft holes 612. A hinge shaft is inserted into the third hinge shaft hole 612 to achieve hinge connection between the first end of the second connecting rod 622 and the first mounting groove 61. A long strip-shaped second mounting hole 22 is provided on the foot pad 2 along its length direction, and a fourth hinge shaft hole 623 is provided at the second end of the second connecting rod 622. A hinge shaft is inserted into the second mounting hole and the fourth hinge shaft hole to achieve movable mounting of the second end of the second connecting rod 622 on the foot pad 2. Of course, the hinge positions of the two sets of connecting rod pairs 62 and the foot pad 2 can also share a single hinge shaft to save on the use of parts.
[0053] Therefore, when the transmission link 5 pushes the first link 621, the first end of the first link moves along the first mounting hole 611. Simultaneously, due to the hinge between the first and second links, the second end of the second link 622 moves along the second mounting hole 22 of the foot pad. The angle between the first and second links decreases, causing the foot pad to fall downwards. When the transmission link pulls the first link, the angle between the first and second links increases, causing the foot pad to rise.
[0054] Furthermore, such as Figure 8-12As shown, for example, the foot pad movement assembly 6 also includes an elastic element 63 with elastic restoring capability. The two ends of the elastic element 63 abut against the second end of the transmission link 5 and the first mounting groove 61, respectively. For example, the elastic element can be a spring, with its two ends abutting against the second end of the transmission link 5 and the inner wall of the first mounting groove 61 away from the transmission link. The elastic element 63 has elastic restoring capability, so that when the transmission link 5 pushes the connecting rod pair 62, the elastic element 63 is compressed, accumulating elastic force, at which point the foot pad 2 falls. When the transmission link 5 pulls the connecting rod pair, the elastic element releases the accumulated elastic force, assisting the transmission link 5 in pulling the connecting rod pair 62, thus lifting the foot pad 2.
[0055] Furthermore, for example, the foot pad motion assembly 6 also includes a rod 64, the first end of which is connected to the second end of the transmission link 5, and the rod 64 is movably inserted into the first mounting groove 61, with an elastic member 63 sleeved on the outside of the rod 64.
[0056] The first end of the insert rod 64 is fixedly connected to the second end of the transmission link 5. For example, the second end of the transmission link can have a receiving hole 54 for accommodating the insert rod and the spring. The first end of the spring abuts in the receiving hole, while the first end of the insert rod is fixedly inserted into the receiving hole. The second end of the insert rod is movably inserted into the first mounting groove. The insert rod 64 makes the compression of the elastic element (such as the spring) more stable. This ensures the stability of the transmission link 5 when compressing the spring, and thus ensures the smoothness of the movement of the foot pad driven by the link pair.
[0057] For example, such as Figure 8-9 As shown, the connection position between the connecting rod pair 62 and the foot pad 2 is set at the upper part of the foot pad 2. Since the lower part of the foot pad needs to be supported by a surface such as a table, in order to prevent the foot pad from slipping and colliding with the table when it falls, an anti-slip layer can be provided on the lower exterior of the foot pad. For example, a layer of anti-slip material such as rubber can be coated on the outer surface of the lower part of the foot pad.
[0058] In this application, the foot pad 2 can be raised or lowered simply by the cooperation of the foot pad motion component 6, gear set 3, and transmission linkage 5. The structure is simple, the transmission method is efficient, and the system complexity is low, which is beneficial to subsequent production and assembly.
[0059] In this application, the position of the feet is not specifically limited, and the transmission linkage structure can be adjusted according to design requirements. The lifting structure of this application occupies less space, meeting the design requirements of ultra-thin laptops. Furthermore, the lifting structure of this application occupies a small area on the exterior surface of the laptop's D-part casing, minimizing its impact on the overall appearance design of the casing.
[0060] In some embodiments, such as Figure 11As shown, the gear set 3 is composed of a starting gear 31, an intermediate gear 32 and a terminal gear 33 meshing in sequence; the starting gear 31 is fixedly connected to the hinge shaft 4 and is used to rotate following the rotation of the hinge shaft 4; the terminal gear 33 meshes with the first end of the transmission link 5.
[0061] The gear set 3 can be composed of a single gear or multiple gears. The gears can be full gears, special gears, or cams; there are no restrictions here. Of course, in this embodiment, the gear set is composed of three gears meshing in sequence. The staggered design of multiple gears can adapt to the internal space of the electronic device while ensuring the transmission effect.
[0062] In this embodiment, the first end surface of the transmission link 5 is formed with teeth for meshing with the terminal gear, and the terminal gear 33 and the starting gear 31 rotate in the same direction.
[0063] For example, such as Figure 7-12 As shown, in order to ensure the smooth operation of the gear set 3, the linkage mechanism of the lifting structure 1 of this application also includes a second mounting groove 7. The second mounting groove 7 is mounted on the hinge shaft 4, and the intermediate gear 32 and the terminal gear 33 are mounted on the second mounting groove 7.
[0064] A third mounting hole 71 is provided on the second mounting groove 7. The third mounting hole 71 is fitted onto the hinge shaft 4. When the hinge shaft rotates, the second mounting groove 7 does not rotate. Figure 11 As shown, the second mounting groove 7 is generally shaped like an inverted "π", and the intermediate gear 32 and the terminal gear 33 are rotatably mounted on the second mounting groove 7. The transmission connecting rod 5, which meshes with the terminal gear 33, is placed on the second mounting groove, with their surfaces in contact. The second mounting groove 7 provides support for the movement of the transmission connecting rod 5. Therefore, the length of the second mounting groove should be as long as possible so that when the transmission connecting rod pushes the connecting rod pair, the first end of the transmission connecting rod is also supported on the second mounting groove and will not fall off. In addition, the first mounting groove 61 also provides supporting force for the movement of the transmission connecting rod.
[0065] In some embodiments, such as Figure 7-9 As shown, the transmission connecting rod 5 is constructed as a single piece. This single-piece structure is simple and easy to manufacture.
[0066] Of course, such as Figure 10As shown, the transmission link 5 can also be constructed as two separate segments spaced apart along a first direction (X direction). These two segments are respectively designated as a first transmission link segment 52 and a second transmission link segment 53. The first transmission link segment 52 is meshed with a gear set for transmission, while the second transmission link segment 53 is linked with the foot pad movement assembly. The second transmission link segment 53 is supported by the first support groove and insert rod of the foot pad movement assembly, restricting its reciprocating movement to the clearance opening 613 of the first support groove. The first transmission link segment 52 is supported by the second support groove 7.
[0067] The first transmission link component 52 and the second transmission link component 53 are spaced apart along a first direction. Taking the opening of a laptop as an example, when the laptop opens counterclockwise, the hinge shaft 4 and the starting gear 31 and the ending gear 33 of the gear set 3 rotate counterclockwise, driving the first transmission link component 52 to move closer to the second transmission link component 53 until the laptop opens to a specific angle. At this point, the first transmission link component 52 and the second transmission link component 53 come into contact. Then, as the opening angle of the laptop increases, the first transmission link component 52 pushes the second transmission link component 53 to move together and compress the spring. The angle of the linkage gradually decreases, driving the foot pad 2 to fall. When the laptop closes, the hinge shaft 4 rotates clockwise. Under the transmission of the gear set 3, the first transmission link component 52 moves away from the second transmission link component 53. The first and second transmission link components separate, the spring releases its elastic force, and pushes the second transmission link component and the linkage back to their initial positions, simultaneously driving the foot pad to rise. Therefore, by setting the transmission linkage as a separate component, we can control the length of the transmission linkage, so that the foot pad movement component can only be driven to move after the laptop screen is opened to a set angle and the transmission linkage has moved to a set distance.
[0068] According to one embodiment of this disclosure, such as Figure 1-6 As shown, this utility model also provides an electronic device, including a system terminal 8, a display terminal 9, and a foot pad 2. The display terminal 9 and the system terminal 8 are linked by a hinge shaft 4, and the device also includes the lifting structure 1 for adjusting the height of the foot pad as described above.
[0069] The hinge shaft 4 has a first end fixedly connected to the display end 9 and rotates with the display end. The second end of the hinge shaft 4 is connected to the system end 8 through the second mounting groove 7 of the lifting structure 1. Specifically, the hinge shaft 4 includes a shaft body 41 and a spindle 42 connected to one end of the shaft body. The first end of the shaft body 41 is fixedly connected to the display end 9. The spindle 42 is equipped with the starting gear 31 of the gear set 3 and the second mounting groove 7, which is fixedly connected to the system end 8.
[0070] In this embodiment, the electronic device includes, but is not limited to, a laptop computer. Taking a laptop computer as an example, the display terminal 9 is rotatably connected to the system terminal 8 via a hinge shaft 4. The first end of the hinge shaft body 41 of the hinge shaft 4 is provided with a mounting plate 411, which is fixedly connected to the display terminal 9. The starting gear 31 has a shaft hole adapted to the spindle 42. The starting gear 31 is sleeved on the spindle 42 through the shaft hole and can rotate with the spindle. The second mounting groove 7 is sleeved on the spindle 42 of the hinge shaft through a third mounting hole 71. When the spindle rotates, the second mounting groove 7 does not rotate with the spindle, and the bottom of the second mounting groove 7 is fixedly connected to the system terminal. Furthermore, multiple friction plates, springs, and adjusting nuts (not shown in the figure) are also installed on the spindle 42 outside the second mounting groove 7 to generate damping in the hinge shaft. The assembly of these friction plates, springs, adjusting nuts, and other components is the conventional setting for damping in the hinge shaft of current laptop computers and will not be described further here.
[0071] In this embodiment, taking a laptop computer as an example, the lifting structure 1 of this application does not occupy additional space on the display end and can be fully shared with the current lightweight and thin design of laptops. The design principle and transmission structure of the lifting structure of this application are located at the system end, so there is no space occupation in the recessed area of the hinge, which can support the current recessed hinge design.
[0072] The lifting structure of this application has advantages in both transmission method and component requirements. Compared with the existing solutions, the lifting structure of this application is more suitable for the ultra-thin design of laptops.
[0073] Taking a laptop computer as an example, the transmission process between the lifting structure and the system and display ends when the lifting structure of this application is installed in a laptop computer is described in detail:
[0074] like Figure 1 , 7 As shown in Figure 9, when the laptop is opened, the display terminal 9 rotates counterclockwise, causing the hinge shaft 4 and the starting gear 31 of the gear set 3 to rotate counterclockwise. Since the starting gear 31 meshes with the intermediate gear 32 and the terminal gear 33, the terminal gear 33 also rotates counterclockwise, causing the transmission link 5 meshing with it to move linearly along the first direction, pushing the connecting rod pair 62 connected to it and compressing the elastic element 63 (spring). The angle between the first link 621 and the second link 622 of the connecting rod pair 62 gradually decreases, driving the foot pad 2 to fall along the second direction. As the opening angle of the display terminal increases, the foot pad protrudes downward, raising the height between the system terminal 8 and the desktop, preventing the bottom edge of the display terminal from contacting the desktop.
[0075] When the laptop closes, the display end 9 rotates clockwise, causing the hinge shaft 4 to rotate and the starting gear 31 of the gear set 3 to rotate clockwise. At the same time, the terminal gear 33 also rotates clockwise, causing the transmission link 5 meshing with it to return along the first direction. The transmission link 5 pulls the linkage pair 62, increasing the angle between the two links of the linkage pair. The linkage pair simultaneously drives the foot pad 2 to lift and retract towards the display end 9, gradually lowering the height of the system end 8 and the desktop. At the same time, the spring gradually releases its elasticity and returns to its original state. As the display end closes, the transmission link 5 and the linkage pair 62 return to their initial positions, waiting for the next time the laptop is opened.
